I can maintain 20g daily carbs and lose weight fast if I remain mostly sedentary. I get weak very fast when I try exercise and even though I get all the electrolytes I get muscle burn. I did this for 5 weeks..went from 248 to 217. Am starting a modified diet tomorrow with 1500 total cals/150 g protein/50 g carb. I hope to tolerate exercise better and the extra carbs will basically be burnt on exercise. If I still feel the carb level impedes my biking and walking will add 10 carbs until I feel comfortable exercising.
The keto diet also appears to help induce autophagy, which helps clear damaged cells from the body, including senescent cells that serve no functional purpose but still linger inside tissues and organs. In animal studies when rats are put on the ketogenic diet, autophagic pathways are created that reduce brain injury during and after seizures. (21)
There are theoretically no restrictions on where the ketogenic diet might be used, and it can cost less than modern anticonvulsants. However, fasting and dietary changes are affected by religious and cultural issues. A culture where food is often prepared by grandparents or hired help means more people must be educated about the diet. When families dine together, sharing the same meal, it can be difficult to separate the child's meal. In many countries, food labelling is not mandatory so calculating the proportions of fat, protein and carbohydrate is difficult. In some countries, it may be hard to find sugar-free forms of medicines and supplements, to purchase an accurate electronic scale, or to afford MCT oils.[54]

Check the nutrition labels on all your products to see if they’re high in carbs. There are hidden carbs in the unlikeliest of places (like ketchup and canned soups). Try to avoid buying products with dozens of incomprehensible ingredients. Less is usually healthier.Always check the serving sizes against the carb counts. Manufacturers can sometimes recommend inconceivably small serving sizes to seemingly reduce calorie and carb numbers.
A: The most common ways to track your carbs is through MyFitnessPal and their mobile app. You cannot track net carbs on the app, although you can track your total carb intake and your total fiber intake. To get your net carbs, just subtract your total fiber intake from your total carb intake. I have written an article on How to Track Carbs on MyFitnessPal.
I think you may be experiencing what I did on an ultra low carb diet. I did try to follow the "20 grams of carbs" approach but it didn't work for me. I felt sluggish, I was tired, and anxious (especially that anxiety!). Having said that, I have Hashimoto's (autoimmune hypothyroid condition) and I can't do very low-carb for that very reason. These days I eat 20-30 grams of net carbs, sometimes up to 50, especially after a workout when my body naturally craves carbs. Keep in mind that some people tend to overemphasise the importance of high ketones while it's not as simple and most people don't even need high ketones: The Ketone Craze - Who Really Benefits From High Ketone Levels? I hope this helps!
Some negative side effects of a long-term ketogenic diet have been suggested, including increased risk of kidney stones and osteoporosis, and increased blood levels of uric acid (a risk factor for gout). Possible nutrient deficiencies may arise if a variety of recommended foods on the ketogenic diet are not included. It is important to not solely focus on eating high-fat foods, but to include a daily variety of the allowed meats, fish, vegetables, fruits, nuts, and seeds to ensure adequate intakes of fiber, B vitamins, and minerals (iron, magnesium, zinc)—nutrients typically found in foods like whole grains that are restricted from the diet. Because whole food groups are excluded, assistance from a registered dietitian may be beneficial in creating a ketogenic diet that minimizes nutrient deficiencies.
Use fat as a lever.  We’ve been taught to fear fat, but don’t! Both keto and low carb are high fat diets. Fat is our source of energy as well as satiety. The key to understand, though, is that fat is a lever on a low carb or keto diet. Carbs and protein stay constant, and fat is the one you increase or decrease (push the lever up or down) to gain or lose weight, respectively. So if your goal is weight loss, eat enough fat to be satisfied, but there’s no need to “get your fats in” once you’re satisfied.
During the ketosis phase of the nutritional intervention, the IWQOL-Lite scores did not change for the sexual life, social anxiety, and work area domains (Table S1). A significant improvement was observed in the physical function and self-esteem scores during this phase. When comparing the visit of reduced ketosis and endpoint with baseline, a significant improvement was found in all domains, except for social anxiety, which did not change throughout the nutritional intervention.
“I follow and recommend a low-carb or keto lifestyle, with and without intermittent fasting, to all of my patients whether or not they have lifestyle-related chronic conditions. I do this because of the health benefits to anyone who follows them, but also because of the science behind them and the impressive clinical results I have seen in my patients. I have recommended the Diet Doctor website for the past 5-6 years as a first-stop to find completely trustworthy information, delicious recipes, great visuals and excellent videos.”

"Obese. That's what the doc said. He said if I didn't change I'd be Morbidly Obese. So stopped eating big macs and started out by walking. But it wasn't really enough to undo the damage. Then I found on Shark Tank. So I found it online and ordered it. I figured, it was worth a shot. I'm glad I did. It jumpstarted my weight loss! I started shedding the weight. I'm down 60 pounds after just 9 months! Thank you - you really saved my life!"
Note: Are you a vegetarian or vegan and want to go on a ketogenic diet? It’s still possible! Just keep in mind that the dietary restrictions can sometimes be a little bit intense. Make sure to plan ahead and prepare to aid your success. To help out, we’ve published articles (with 7 day meal plans included) for both the vegetarian ketogenic diet and the vegan ketogenic diet.
Throughout the study, the patients completed a maximum of 10 visits with the research team (every 15 ± 2 days), of which 4 were for a complete physical, anthropometric, and biochemical assessment; the remaining visits were to manage adherence and evaluation of potential side effects. These 4 visits were made according to the evolution of each patient through the steps of ketosis as follows: visit C-1 (baseline), normal level of ketone bodies; visit C-2, maximum ketosis; visit C-3, reduction of ketotic approach because of partial reintroduction of normal nutrition; visit C-4, no ketosis (Supplemental Fig. 1). The total ketosis state lasted for 60 to 90 days only. In all of the visits, patients received dietary instructions, individual supportive counsel, and encouragement to exercise on a regular basis using a formal exercise program. Additionally, a program of telephone reinforcement calls was instituted, and a phone number was provided to all participants to address any concerns.
Wondering what fits into a keto diet — and what doesn’t? “It’s so important to know what foods you’ll be eating before you start, and how to incorporate more fats into your diet,” says Kristen Mancinelli, RD, author of The Ketogenic Diet: A Scientifically Proven Approach to Fast, Healthy Weight Loss, who is based in New York City. We asked her for some guidelines.

In theory, a ketogenic diet that increases carbohydrate loads for cardio exercise seems perfect. However, the side effects of a ketogenic diet can include dehydration, malnutrition and constipation. According to the Mayo Clinic website, ketogenic plans also can lead to kidney stones. In addition, the ketogenic diet does not give you the nutrition you need to be healthy. Instead, try cutting portion sizes and counting calories; this also can force your body to burn fat while still providing you with balanced nutrition, including proteins, carbohydrates, fiber and fat. As with any diet, you should discuss a ketogenic diet with your doctor.
Carrying out a very low-calorie diet plan is one of the quickest and best methods to lose sizable weight. Its principle is founded on decades-long research that proves how a diet that lessens or removes carbohydrates, prioritizes lean proteins and leafy vegetables and allows a tiny amount of good fat can change the way the body's energy system operates. The diet causes ketosis, from where the body is driven by ketones instead of glucose. Through following a menu of a cautious selection of recommended food items, a very low-calorie diet kills food cravings and enables you to feel sufficiently full without excessive food intake.
The only issue with keto, is really that I’m afraid that it might be hard to up my calories to a maintenance weight now that I’ve gotten a taste preference for the rich assortment of foods with no carbs in them. I’m satisfied with less calories than I will need after my excess fat is burned off… but , maybe I bet my body will send more hunger signs once there isn’t anymore body fat in the cupboard to use instead of what goes down my throat.
After reading the FAQ (which is really great, btw), one of the things I'm wondering about is whether the low calorie approach works well in conjunction with Keto. I like the general idea, but with my weight, I'm thinking I would like to try to keep my overall calorie intake low, in addition to cutting carbs, refined sugars, etc. out of my diet. It doesn't seem to be expressly forbidden, but it doesn't seem to be what many people do, based on what i've read so far. Basically, I think in addition to this approach to nutrition, I'd also like to keep my calorie deficient high. I think both would go a long way towards helping me be healthier.
People suffering from diabetes and taking insulin or oral hypoglycemic agents suffer severe hypoglycemia if the medications are not appropriately adjusted before initiating this diet. The ketogenic diet is contraindicated in patients with pancreatitis, liver failure, disorders of fat metabolism, primary carnitine deficiency, carnitine palmitoyltransferase deficiency, carnitine translocase deficiency, porphyrias, or pyruvate kinase deficiency. People on a ketogenic diet rarely can have a false positive breath alcohol test. Due to ketonemia, acetone in the body can sometimes be reduced to isopropanol by hepatic alcohol dehydrogenase which can give a false positive alcohol breath test result. 
But what about body fat? Hall and Guo investigated 20 controlled feeding studies that reported changes in body fatness on equal-calorie diets differing in fat and carbohydrate content. They found that each diet has similar effects on body fatness, which makes sense when you consider the finding that neither diet provides a significant metabolic advantage.   (Yet higher-carbohydrate diets seem to cause a slightly more substantial loss of body fat per calorie — a 16 gram per day difference.)

Participants completed take-home food records (4 consecutive days, including a weekend) collected at baseline and at weeks 2, 8, and 16 during the study. Participants were given handouts with examples of how to complete the records. A registered dietician analyzed the food records using a nutrition software program (Food Processor SQL, ESHA Research, Inc., Salem, OR).
Hi Sam, it won’t work. You will be incredibly hungry and you won’t have any energy. The idea of the keto diet is to get your body used to use fat to burn energy not carbs. Since you won’t be eating carbs energy has to come from “something” and it can’t be protein. I can’t recall what happens when you have too much protein when doing Keto but it was something scary. In general, I do not recommend the Keto diet without some sort of supervision by your doctor or nutritionist that can watch your process and progress.

The ketogenic diet is not a benign, holistic, or natural treatment for epilepsy; as with any serious medical therapy, complications may result.[28] These are generally less severe and less frequent than with anticonvulsant medication or surgery.[28] Common but easily treatable short-term side effects include constipation, low-grade acidosis, and hypoglycaemia if an initial fast is undertaken. Raised levels of lipids in the blood affect up to 60% of children[38] and cholesterol levels may increase by around 30%.[28] This can be treated by changes to the fat content of the diet, such as from saturated fats towards polyunsaturated fats, and if persistent, by lowering the ketogenic ratio.[38] Supplements are necessary to counter the dietary deficiency of many micronutrients.[18]


There are theoretically no restrictions on where the ketogenic diet might be used, and it can cost less than modern anticonvulsants. However, fasting and dietary changes are affected by religious and cultural issues. A culture where food is often prepared by grandparents or hired help means more people must be educated about the diet. When families dine together, sharing the same meal, it can be difficult to separate the child's meal.

In some countries, it may be hard to find sugar-free forms of medicines and supplements, to purchase an accurate electronic scale, or to afford MCT oils.[54]
The keto diet works for such a high percentage of people because it targets several key, underlying causes of weight gain — including hormonal imbalances, especially insulin resistance coupled with high blood sugar levels, and the cycle of restricting and “binging” on empty calories due to hunger that so many dieters struggle with. In fact, these are some of the direct benefits of the keto diet.
In general, you want to eat the minimum amount of protein to preserve lean body mass and not overtax your kidneys. If you eat too much protein, the excess converts to glucose through a process called gluconeogenesis. You don’t want that to occur in ketosis. Instead, eat anti-inflammatory protein—at the minimum amount to preserve or build lean body mass. My favorite sources are wild-caught fish, grass-fed and -finished beef and wild meats (elk, bison, etc.), pasture-raised poultry, nuts, and seeds. Make sure fish has more selenium (which helps protect the brain) than mercury, to mitigate heavy metal toxicity. Good sources that have a safe selenium/mercury ratio include: tuna, opah, wahoo, spearfish, swordfish.
You may also want to try a cyclical keto diet, or carb cycling. You follow the standard keto diet for 6 days of the week, when you eat less than 50 grams of net carbs a day. But on one day of the week, you increase your carb intake to roughly 150 grams of net carbs. Doing this satisfies any carb cravings you might have, making it easier to sustain keto in the long-run. Learn more about the benefits of carb cycling and weight loss here.

Hi Kim, there are several factors for developing autoimmune diseases, including Hashimoto's. I believe that in my case it was a combination of high-carb & low-calorie dieting that have contributed to it. I found out by accident because I went for allergy testing where they discovered I had thyroid antibodies. You should definitely avoid following a low-calorie diet (1000 kcal is not enough). Have a look at this tool: KetoDiet Buddy - Easy Macro Calculator for the Ketogenic Diet
Ketosis means that your body is in a state where it doesn't have enough glucose available to use as energy, so it switches into a state where molecules called ketones are generated during fat metabolism. Ketones can be used for energy. A special property of ketones is that they can be used instead of glucose for most of the energy needed in the brain, where fatty acids can't be used. Also, some tissues of the body prefer using ketones, in that they will use them when available (for example, the heart muscle will use one ketone in particular for fuel when possible).
The VLCK diet was used because of its ability to produce a rapid and well-tolerated weight loss with a ketogenic phase that lasts 60-90 days and a final result of 20 kg of weight reduction at 4 months. The rapid reduction in weight is the probable explanation of the positive effects of this dieting approach, which are evident 1 and 2 years later (12, 13). Four different stages occurred with the VLCK diet used: a basal stage with obese body weight and no ketosis, a second stage with extreme ketosis and marked body weight loss, a third stage with body weight loss and declining ketosis, and a fourth stage with weight loss and no ketosis. Body composition was studied with the 3 techniques at each of these stages.

If you do try the diet outside of medical supervision, Kizer says it’s important to test your urine with urinalysis ketone test strips to ensure your ketone levels don’t become dangerously high. Ketone urine test strips are also used by people with diabetes to determine if they’re at risk for ketoacidosis (DKA), a life-threatening complication that occurs when an individual doesn’t have enough insulin in their body. (Healthy ketosis is considered 0.5 to 3.0 mM blood ketones.)
“As a physician I was frustrated and distressed by patients’ worsening health and by the spiraling health care costs caused by diabetes, obesity and other chronic conditions, all linked to the food we eat. We help our patients improve their health and optimize their weight with prescribed lifestyle modification, teaching them the link between unhealthy, refined and processed foods and chronic illness. Our growing database of patients who have lost weight and improved cardio-metabolic markers demonstrates the benefits of low-carbohydrate, whole-food diets. In short, reducing the carbohydrate content of our meals controls hunger, promotes weight loss, and improves health.”
Wilder's colleague, paediatrician Mynie Gustav Peterman, later formulated the classic diet, with a ratio of one gram of protein per kilogram of body weight in children, 10–15 g of carbohydrate per day, and the remainder of calories from fat. Peterman's work in the 1920s established the techniques for induction and maintenance of the diet. Peterman documented positive effects (improved alertness, behaviour, and sleep) and adverse effects (nausea and vomiting due to excess ketosis). The diet proved to be very successful in children: Peterman reported in 1925 that 95% of 37 young patients had improved seizure control on the diet and 60% became seizure-free. By 1930, the diet had also been studied in 100 teenagers and adults. Clifford Joseph Barborka, Sr., also from the Mayo Clinic, reported that 56% of those older patients improved on the diet and 12% became seizure-free. Although the adult results are similar to modern studies of children, they did not compare as well to contemporary studies. Barborka concluded that adults were least likely to benefit from the diet, and the use of the ketogenic diet in adults was not studied again until 1999.[10][14]
According to one hypothesis, low-carb diets have a distinct “metabolic advantage” over diets with higher carbohydrate content when the amount of calories consumed are the same.3 This metabolic advantage is essentially an increase in the expenditure of energy (calories) on the low-carb diet. Factors that may account for this higher rate of calorie burning include:
Great information and questions! I finish eating before 6 and don’t have anything until noon or sometimes later, the next day! I do drink water and plain herbal tea. I take Omega 3’s, 2 Tbsps. of cold pressed virgin olive oil with lemon in water, in the morning! Around noon I have my BP coffee with butter and coconut cream. Primarily eggs, avocado, chicken, stir fry’s, nuts (mostly almonds), etc.
“As a family doctor, I not only lost weight and improved my own health with the low-carb diet, I also inspired colleagues and patients alike to follow this lifestyle and reap its benefits. It has now become a powerful tool I use in my daily practice to help treat and reverse obesity, diabetes, fatty liver, PCOS, and chronic pain. I refer all my English-speaking patients to the Diet Doctor website and I also use it during visits as a counseling tool. Inspired by Diet Doctor, I have created my own website to cater to French-speaking patients!”

People use a ketogenic diet most often to lose weight, but it can help manage certain medical conditions, like epilepsy, too. It also may help people with heart disease, certain brain diseases, and even acne, but there needs to be more research in those areas. Talk with your doctor first to find out if it’s safe for you to try a ketogenic diet, especially if you have type 1 diabetes.
The good news, however, is that following a well-formulated ketogenic diet should help increase HDL while lowering triglyceride levels. LDL will likely remain the same or potentially increase in order to efficiently transport triglycerides to cells to metabolize for energy. Again, LDL will likely become more of the pattern A type which is a highly beneficial shift.
d) Or does the entire question revert back to a classic calorie counting exercise? In this case, I’ll eat the minimum amount of protein that is needed to prevent my muscles from being cannibalized (for energy) and for the rest, I’ll limit my dietary fat intake per day to a level, where its energy + energy currently obtained from adipose tissue match my total energy need? (I’ll leave gluconeogenesis out of this equation for simplicity.) If this is the case, I’ll lose adipose tissue, i.e. lose weight, but the interesting question still remains: How much energy can my body extract from the adipose tissue at its best? How can I maximize the share of energy coming from adipose tissue instead of dietary fat?
The ketogenic diet reduces seizure frequency by more than 50% in half of the patients who try it and by more than 90% in a third of patients.[18] Three-quarters of children who respond do so within two weeks, though experts recommend a trial of at least three months before assuming it has been ineffective.[9] Children with refractory epilepsy are more likely to benefit from the ketogenic diet than from trying another anticonvulsant drug.[1] Some evidence indicates that adolescents and adults may also benefit from the diet.[9]

A meta-analysis of 13 randomized controlled trials following overweight and obese participants for 1-2 years on either low-fat diets or very-low-carbohydrate ketogenic diets found that the ketogenic diet produced a small but significantly greater reduction in weight, triglycerides, and blood pressure, and a greater increase in HDL and LDL cholesterol compared with the low-fat diet at one year. [10] The authors acknowledged the small weight loss difference between the two diets of about 2 pounds, and that compliance to the ketogenic diet declined over time, which may have explained the more significant difference at one year but not at two years (the authors did not provide additional data on this).

“As a psychiatrist who practices traditional and holistic (integrative) psychiatry, I find my patients are always looking for non-pharmacological ways to improve both their psychological and physical health. Diet Doctor has proven to be an excellent and reliable resource to help my patients develop and maintain healthy lifestyle choices with low-carb and ketogenic diets. My patients are thrilled with the extensive variety of recipe options that are easy to prepare as well as the informative videos on relevant health issues. I am equally thrilled with the positive benefits in my patients’ mood, anxiety, and cognitive clarity.”
When you’re on a ketogenic diet, fatty acids are released from your body fat and insulin levels decrease. When insulin levels decrease, your kidneys will excrete more water (you’ll notice an increase in the frequency of trips to the bathroom), sodium and potassium. As a result, your blood pressure can plummet. Dizziness, fatigue and sudden weakness are symptoms of low blood pressure. Leg cramps may also occur from dehydration.
Determining the diet that best suits you is a very individual choice, so it's hard to make a general recommendation for one type of diet. You can lose weight through a variety of eating styles, whether you choose a low-carb, low-fat, keto or Mediterranean diet, or another one. But in general, eating lots of fruits and vegetables, lean proteins and whole grains is going to help you lose weight and achieve a healthy lifestyle.
Infants and patients fed via a gastrostomy tube can also be given a ketogenic diet. Parents make up a prescribed powdered formula, such as KetoCal, into a liquid feed.[19] Gastrostomy feeding avoids any issues with palatability, and bottle-fed infants readily accept the ketogenic formula.[31] Some studies have found this liquid feed to be more efficacious and associated with lower total cholesterol than a solid ketogenic diet.[18] KetoCal is a nutritionally complete food containing milk protein and is supplemented with amino acids, fat, carbohydrate, vitamins, minerals and trace elements. It is used to administer the 4:1 ratio classic ketogenic diet in children over one year. The formula is available in both 3:1 and 4:1 ratios, either unflavoured or in an artificially sweetened vanilla flavour and is suitable for tube or oral feeding.[51] Other formula products include KetoVolve[52] and Ketonia.[53] Alternatively, a liquid ketogenic diet may be produced by combining Ross Carbohydrate Free soy formula with Microlipid and Polycose.[53]
Take a multivitamin. “Because you are removing grains, the majority of fruit, some vegetables, and a significant amount of dairy from your menu, a multivitamin is good insurance against any micronutrient deficiencies,” says Jadin. Depending on what your individual overall diet looks like, Jadin says you might also need to add a calcium, vitamin D, and potassium supplement.
Nurse practitioners (NP) are advanced practice registered nurses that manage acute and chronic medical conditions, both physical and mental, through history and physical exam and the ordering of diagnostic tests and medical treatments. NPs are qualified to diagnose medical problems, order treatments, perform advanced procedures, prescribe medications, and make referrals for a wide range of acute and chronic medical conditions within their scope of practice. Their education includes a Bachelor of Science in Nursing (BSN) or other undergraduate degree, and requires a license as a registered nurse (RN) and experience as an RN in a health care setting. They must graduate from an accredited graduate (MSN) or doctoral (DNP) program and achieve a board certification.
A ketogenic diet also has been shown to improve blood sugar control for patients with type 2 diabetes, at least in the short term. There is even more controversy when we consider the effect on cholesterol levels. A few studies show some patients have increase in cholesterol levels in the beginning, only to see cholesterol fall a few months later. However, there is no long-term research analyzing its effects over time on diabetes and high cholesterol.
The low glycaemic index treatment (LGIT)[49] is an attempt to achieve the stable blood glucose levels seen in children on the classic ketogenic diet while using a much less restrictive regimen. The hypothesis is that stable blood glucose may be one of the mechanisms of action involved in the ketogenic diet,[9] which occurs because the absorption of the limited carbohydrates is slowed by the high fat content.[5] Although it is also a high-fat diet (with approximately 60% calories from fat),[5] the LGIT allows more carbohydrate than either the classic ketogenic diet or the modified Atkins diet, approximately 40–60 g per day.[18] However, the types of carbohydrates consumed are restricted to those that have a glycaemic index lower than 50. Like the modified Atkins diet, the LGIT is initiated and maintained at outpatient clinics and does not require precise weighing of food or intensive dietitian support. Both are offered at most centres that run ketogenic diet programmes, and in some centres they are often the primary dietary therapy for adolescents.[9]
A cyclic ketogenic diet (or carb-cycling) is a low-carbohydrate diet with intermittent periods of high or moderate carbohydrate consumption. This is a form of the general ketogenic diet that is used as a way to maximize fat loss while maintaining the ability to perform high-intensity exercise. A ketogenic diet limits the number of grams of carbohydrate the dieter may eat, which may be anywhere between 0 and 50g per day. The remainder of the caloric intake must come primarily from fat sources and protein sources in order to maintain ketosis (the condition in which the body burns fats and uses ketones instead of glucose for fuel).

There are three instances where there’s research to back up a ketogenic diet, including to help control type 2 diabetes, as part of epilepsy treatment, or for weight loss, says Mattinson. “In terms of diabetes, there is some promising research showing that the ketogenic diet may improve glycemic control. It may cause a reduction in A1C — a key test for diabetes that measures a person’s average blood sugar control over two to three months — something that may help you reduce medication use,” she says.
The ketogenic diet is not a benign, holistic, or natural treatment for epilepsy; as with any serious medical therapy, complications may result.[28] These are generally less severe and less frequent than with anticonvulsant medication or surgery.[28] Common but easily treatable short-term side effects include constipation, low-grade acidosis, and hypoglycaemia if an initial fast is undertaken. Raised levels of lipids in the blood affect up to 60% of children[38] and cholesterol levels may increase by around 30%.[28] This can be treated by changes to the fat content of the diet, such as from saturated fats towards polyunsaturated fats, and if persistent, by lowering the ketogenic ratio.[38] Supplements are necessary to counter the dietary deficiency of many micronutrients.[18]
1st Tippy Tale is now live!📚My 31-Day Keto Diet Transformation! (Link in bio) Truth: The last few months of 2017 was rough for me. With so many life changes happening, I found myself at the corner of mental and physical exhaustion. Bottling so much inside, I let my stress take the best of me. I started to neglect my health in ways I haven’t done in years. I desperately needed positive change. I desperately needed myself back... . . I talk about the horrible side effects that happened to me during those 3 months of neglect and my 31-day Keto diet journey to reset my lifestyle. You can watch my YouTube video (link in bio) or read my blog post on my website (tippytales.com) for details on the Keto diet, how I went about doing it, my honest opinion, my results, my current status 2 months post my reset and if I am making it a lifestyle.🤔☺️ . . Putting yourself out there and showing a before and after picture is scary for a lot of people. I am no different to this thought but I needed to share this. Why? Quite frankly because I am proud and I know how hard I worked to get myself back. Although my aesthetics did change, I know the bigger change is within. I can full heartedly say I love my body and the woman I’ve become from this fight to get myself back. If this inspires one person to believe in themselves a little more today than yesterday then these series of awkward poses served its purpose.😜 . . We are all human and some times we have setbacks in life. I believe setbacks are there for a reason..to test us. To test how bad we truly and deeply want it. Besides, what’s a good story without a killer comeback?! Not a good one in my humble opinion.😉 #TippyTales 📚

A randomized control study in 2017 examined the effects of a ketogenic diet combined with Crossfit training on body composition and performance. Results from this study concluded that subjects following a low-carbohydrate ketogenic diet (LCKD) significantly decreased body weight, body fat percentage and fat mass compared to those in the control group[*].
Ketosis was determined by measuring ketone bodies, specifically β-hydroxy-butyrate (β-OHB), in capillary blood by using a portable meter (GlucoMen LX Sensor, A. Menarini Diagnostics, Neuss, Germany; sensitivity <0.2 mmol/L). As with anthropometric assessments, all the determinations of capillary ketonemia were made after an overnight fast of 8 to 10 h. These measurements were performed daily by each patient during the entire VLCK diet, and the corresponding values were reviewed on the machine memory by the research team to control adherence. Additionally, β-OHB levels were determined at each visit by the physician in charge of the patient. Glucose, insulin, HbA1C were performed using an automated chemistry analyzer (Dimension EXL with LM Integrated Chemistry System, Siemens Medical Solutions Inc. (Tarrytown, NY, USA). Thyroid-stimulating hormone (TSH), free thyroxine (FT4), and free triiodothyronine (FT3) were measured by chemiluminescence using ADVIA Centaur (Bayer Diagnostics, Tarrytown, NY, USA). The overnight fasting plasma levels of ghrelin and leptin were measured using commercially available ELISA kits (Millipore, Burlington, MA, USA). The fasting plasma levels of dopamine was tested by high pressure liquid chromatography (HPLC; Reference Laboratory, Barcelona, Spain).
Patients were invited to complete a battery of psychological tests to assess performance in the domains of food cravings, quality of life (QoL), daytime sleepiness and sleep quality, sexual functioning, and physical activity through the course of the nutritional intervention. The psychological tests were selected for availability of multiple test versions, well-stablished psychometric properties, and accepted clinical use.
Once your body adapts to using fat for fuel (can take anywhere from a couple of weeks to over a month) you'll find your apetite changes and it's very easy to eat very low calorie - you won't feel hungry as often and you'll have an easier time recognizing when you should stop eating. A lot of people on keto naturally fall in to some sort of intermittent fasting (eating only 1, 4, 6 or 8 hours of the day and fasting the rest) because they just aren't hungry.
“We know that when we have fats in our diet like MUFAs, they not only fill us up but keep cholesterol levels lower,” says Keatley. Olive oil is great for light sauteing, using in dressings, or drizzling over cooked meats or vegetables as a finishing oil. One tablespoon (tbsp) offers 119 calories and 13.5 g of fat, only 2 g of which are saturated fat, according to the USDA.
My husband is doing this diet and I was making him bean soup with sausage for dinner, but I’m reading beans are a food to avoid, even being a high fiber food is that really true? Beans were always a good I was encouraged to eat in many other diets. I’m new to keto and don’t want to hinder his process. Would appreciate your advice because I’ve already got the beans cooking. Oh they are the dry beans, not canned.

The classic ketogenic, or “keto,” diet calls for consuming a low amount of carbs, a high amount of fat, and a moderate amount of protein. But in the current study, participants induced ketosis by getting the majority of their calories from protein, a small amount from fat, and a low amount from carbs. One of the side effects of very low-calorie diets is loss of lean muscle mass, but on the adjusted keto diet in the study, participants preserved lean muscle mass. Researchers attributed the preservation of lean muscle mass to participants’ sustained RMR, and their results support those of a prior study, published in February 2017 in the Journal of Clinical Endocrinology and Metabolism.

I’m discouraged to see that nowhere in the article nor in the comments is there a mention of a diet’s best fit to genetics. Consider if someone is an APOE E2 carrier and/or has certain polymorphisms of the APO5 gene. These are quite rare in Okinawa but much more prevalent in the USA (12% of the population). According to a number of well-designed studies, these genetic characteristics point to a higher fat, lower carbohydrate diet as beneficial and even a “moderate” carb diet as problematic.
Melinda – I’m afraid there’s no getting around the fact that one of the Keto requirements is to *calculate your macros,* based on the amount of calories you need to consume each day, in order to (a) maintain your current weight level, or (b) lose weight. Go to an online Keto macro calculator – there’s one linked to a good one on this site, further up the thread. They are generally very easy to use. Then stick to your calculated results, with trust and patience. It may be slow, but you will absolutely see results. I did – and I’ve tried absolutely everything. I barely have time to exercise, but I still lost at least a couple of dress sizes, and I feel absolutely amazing – no more brain fog, tons of energy – maybe too much energy! And best of all, I’m no longer miserable about food, because on Keto, everything is delicious! One final thing in the interest of full disclosure – I am an uber-clean-Keto advocate. I put in the work to eat only healthy fats and carbs from healthy sources. I’m pescatarian – no meats except seafood. I also carefully limit my saturated fat intake to 10% of total calories (the recommended daily allowance), to keep my genetically problematic cholesterol level from skyrocketing, as it did when I first began. This is all working well for me so far – I was able to cut 40 points from my abnormally high LDL (bad cholesterol) level within three months, And hope to get it down to normal levels in three more months. You do want to make sure you get your regular physical exams and monitor your blood work whenever you change your nutritional lifestyle. I wish you the best!

Unfortunately, there’s no long-term data on ketogenic diets versus other diets. In a 2015 Italian study, those on a ketosis diet lost 26 pounds in three months. About half of the participants stayed on the diet for a year but lost little additional weight in the next nine months. People in a 2014 Spanish study who followed a very-low-calorie ketogenic diet lost an average of 44 pounds in a year—but a third of them dropped out, possibly because it was too hard to maintain.
If you want to try a ketogenic diet, be aware that you'll have to adjust it for your individual metabolism and experiment with the right balance of carbs and calories. While some low-carbohydrate dieters find they are able to break stalls in their weight loss, others find that it is more difficult for them to stay in this state. You may want to consult a registered dietitian to build keto-friendly menus for you that will meet your nutritional needs. Be sure to keep your health care provider informed when you start a new diet, especially if you have ongoing health conditions.

In 1863, William Banting, a formerly obese English undertaker and coffin maker, published "Letter on Corpulence Addressed to the Public", in which he described a diet for weight control giving up bread, butter, milk, sugar, beer, and potatoes.[46] His booklet was widely read, so much so that some people used the term "Banting" for the activity usually called "dieting".[47]
Lazy keto diet: Last but not least, the Lazy keto diet often gets confused with dirty keto … but they’re different, as the “lazy” refers to simply not carefully tracking the fat and protein macros (or calories, for that matter). Meanwhile, the one aspect that remains strict? Not eating over 20 net carb grams per day. Some people find this version less intimidating to start with or end with … but I will caution that your results will be less impressive.
Thank you, Dr. Jockers. I really appreciate your reply. I was wondering if insulin resistance would make my cholesterol go up on the ketogenic diet from a total of 220 before I went on it to 378 after being on it for six months. I have always been in a healthy weight range for my height, but I have always been extremely hungry most of the time. I really got on the ketogenic diet hoping that this would be regulated after being on it for some time, but it hasn’t helped that much. Would this signify that insulin resistance may be the culprit for my sudden rise in cholesterol even though I am following the ketogenic diet perfectly?

When trying to shift from a high carb diet to a ketogenic diet, cravings can definitely get strong. It’s always best to try to clean house before you start so that you don’t have food around you that can lead to cravings. We recommend that when switching to keto, you restrict using sweeteners completely for the first 30 days. It normally leads to breaking sugar addiction and ultimately not having cravings.

You can have a completely smooth transition into ketosis, or…not. While your body is adapting to using ketones as your new fuel source, you may experience a range of uncomfortable short-term symptoms. These symptoms are referred to as “the keto flu.” Low-sodium levels are often to blame for symptoms keto flu, since the kidneys secrete more sodium when you’re in ketosis, says Volek. A few side effects:

Some people on a keto or low carb diet choose to count total carbs instead of net carbs. This makes it more difficult to fit in more leafy greens and low carb vegetables (which are filled with fiber), so you should only try that if you don’t get results with a net carb method. And, start with reducing sugar alcohols and low carb treats before deciding to do a “total carbs” method.


Transformation Tuesday::: I wore shorts once last year, i felt good because they were a size 16 I think, down from a size 20. My size 2 shorts in the after picture are now too big. About a year between these pictures and at least 100lbs. I was working out, but @coach_jmo had just had the food conversation with me. It was vacation time and I was sad about not being beach ready in a little over 3 months. 😂 I was still making bad choices to help me cope with my weight gain from Postpartum depression and anxiety. I was still eating horribly, with cheat weekends and lots of pizza. 😂 I still thought exercising was enough to help me reach my goals. Working out 7 days a week with my trainer and a Ketogenic diet have changed my life. Down from a size 18/20 to a Size 0/2, over 130 pounds, and over 115 inches. 🎉🙌🎊
The ADA say low-carbohydrate diets can be useful to help people with type 2 diabetes lose weight, but that these diets were poorly defined, difficult to sustain, unsuitable for certain groups of people and that, for diet composition in general, "no single approach has been proven to be consistently superior".[13] Overall, the ADA recommend people with diabetes should be "developing healthy eating patterns rather than focusing on individual macronutrients, micronutrients, or single foods". They recommended that the carbohydrate in a diet should come from "vegetables, legumes, fruits, dairy (milk and yogurt), and whole grains"; highly-refined foods and sugary drinks should be avoided.[13]
Certain studies suggest that keto diets may “starve” cancer cells. A highly processed, pro-inflammatory, low-nutrient foods can feed cancer cells causing them to proliferate. What’s the connection between high-sugar consumption and cancer? The regular cells found in our bodies are able to use fat for energy, but it’s believed that cancer cells cannot metabolically shift to use fat rather than glucose.

“I have been a UK family doctor since 1990, and discovered the low-carb and keto ways of life in 2014. Until then, I had never seen a way of eating that resulted in normal weight and improvements in other health problems like diabetes, epilepsy, arthritis, and asthma. When I discovered Diet Doctor I was very impressed, and loved the recipes. I now run low-carb courses for the public and health care professionals.”


May cause irregularity. Dramatically increasing your fat intake while drastically cutting your carb intake may cause gastrointestinal issues, ranging from constipation to diarrhea. This is something that should resolve itself when your body gets fat-adapted [5]. There is also the potential for nausea, particularly when switching from a low-fat diet to the ketogenic diet. It can take a while for the gall bladder, pancreas, and liver to adapt to digesting high amounts of fat [17].

The classic ketogenic diet is not a balanced diet and only contains tiny portions of fresh fruit and vegetables, fortified cereals, and calcium-rich foods. In particular, the B vitamins, calcium, and vitamin D must be artificially supplemented. This is achieved by taking two sugar-free supplements designed for the patient's age: a multivitamin with minerals and calcium with vitamin D.[18] A typical day of food for a child on a 4:1 ratio, 1,500 kcal (6,300 kJ) ketogenic diet comprises three small meals and three small snacks:[28]
Short-term results for the LGIT indicate that at one month approximately half of the patients experience a greater than 50% reduction in seizure frequency, with overall figures approaching that of the ketogenic diet. The data (coming from one centre's experience with 76 children up to the year 2009) also indicate fewer side effects than the ketogenic diet and that it is better tolerated, with more palatable meals.[18][50]
I was a Corpsman (not a corpse-man as some recent somewhat fanatical president would say), and I can tell you many stories of Marines and Sailors who maintained restrictive diets (aka picky eaters). Most obvious was lack of sustaining energy (hypoglycemia) at mile 15 (with 80lbs of gear including a 6.5lb rifle and 200 rnds of ammo, etc.) and depletion of essential vitamins, electrolyte imbalance. They were always the first to collapse and have to hear me scold “see I told you so.” An IV of D5W usually does the trick (D is for dextrose, OMG!)
