Low-carbohydrate diets are associated with increased mortality, and they can miss out on the health benefits afforded by high-quality carbohydrate such as is found in legumes including grain legumes or pulses, and fruit and vegetables.[3][4] Disadvantages of the diet might include halitosis, headache and constipation, and in general the potential adverse effects of the diet are under-researched, particularly for more serious possible risks such as for bone health and cancer incidence.[5]
Keto can promote fat loss—in the right person. For people who are sugar burners and can’t kick their sugar cravings, keto can be very helpful, because the increased fat is satisfying and curbs sugar cravings, and people eat less overall compared to their baseline diet. So, I occasionally prescribe it for weight (fat) loss, and for help with specific hormone imbalances involving insulin and stubborn fat gain because it improves insulin sensitivity. This includes patients struggling with: obesity, weight-loss resistance (assuming the thyroid is healthy), and PCOS with insulin resistance and weight gain.
Drink lots of water. This is especially crucial on a low carb or keto diet. Why? When you eat carbohydrates, your body stores the extra as glycogen in the liver, where they are bound to water molecules. Eating low carb depletes this glycogen, which allows you to burn fat – but it also means you are storing less water, making it easier to get dehydrated. Instead of the traditional recommendation of 8 cups of water per day, aim for 16 cups when following a low carb lifestyle.
A ketogenic diet changes this. When you go keto, your body goes into ketosis, a glycogen-deprived state from the low carb intake. Instead, fat is oxidized to produce energy, resulting in ketones. Unlike glucose, which provides quick bursts of energy, the energy from fat burns slower. As a result, you may avoid sugar crashes right after a high-carb meal being on a keto diet.

Bulk buy and cook. If you’re someone who doesn’t like to spend a lot of time in the kitchen, this is the best of both worlds. Buying your food at bulk (specifically from wholesalers) can reduce the cost per pound tremendously. Plus, you can make ahead food (bulk cook chicken thighs for pre-made meat, or cook entire meals) that are used as leftovers, so you spend less time cooking.
The fatal flaw in this reasoning is that we don’t have the same energy expenditure as our fat mass increases. I just want to point out that the calories in/calories out system don’t claim to predict exact energy expenditure, weight gain, or weight loss. It’s just a system that shows how energy intake and expenditure are linked with energy storage and energy loss for the average person.
The data are presented as mean (standard deviation). All statistical analyses were carried out using Stata statistical software, version 12.0 (Stata, College Station, TX). A P < 0.05 was considered statistically significant. Changes in the different variables of interest from baseline and throughout the study visits were analyzed following a repeated measures design. A repeated measures analysis of variance test was used to evaluate differences between different measurement times, followed by post hoc analysis with Tukey’s adjustment for multiple comparisons. In addition, linear regression analyses were used to evaluate the accuracy of MF-BIA and ADP in comparison with DXA, because DXA is considered the reference technique in the estimation of body composition in clinical research (26). Finally, the Bland-Altman approach was also used to assess the accuracy of MF-BIA and ADP against DXA in the estimation of FM%.
First, a little background: Eric Westman, MD, director of the Duke Lifestyle Medical Clinic, explained to Health in a previous interview that in order to successfully follow the keto diet, you need to eat moderate amounts of protein, reduce your carb intake, and increase fats. When you reduce your carb consumption, your body turns to stored fat as its new fuel source—a process called ketosis. To stay in ketosis, followers of the keto diet must limit their carbs to 50 grams a day, Dr. Westman says.
Many unhealthy foods easily meet keto’s low-carb, high-fat criteria. However, that doesn’t mean you can or should eat them freely. “A huge benefit to following the keto diet is that the vast majority of processed food is removed with the removal of grains,” Santo says. “Unfortunately, poor-quality dairy, meat, and veggies may fill the gap.” Look for healthier sources of protein and fat, such as grass-fed meats, and limit processed dairy (think cheese singles) as much as possible.
I’ve been trying this keto diet that my dr.and daughter recommended, it’s been close to a week. I’ve changed my food intake, no bad carbs that I know of, was a huge chip addict stopped all that with no cravings. I’m not seeing any results I’m getting discouraged and everything sounds so complicated watching this, measuring that, I don’t have a clue what I’m doing. just that I stopped bread,pasta,poratoes,rice all those kind of carbs.I’m drinking more water eating green vegetables and trying to increase my fat intake. I don’t feel motivated to exercise which probably doesn’t help and have 100-130 to lose. I need help I don’t understand or have the time create a lot of meals and measure my fat,protein and carb intake.
Hi Martina thanks for sharing. I've been in keto for a good 2 years now. From 138lbs my weight is now at 118-120lbs and I am 5'4 ft 38 years old. I never felt better in my life since i decided to do keto. I really like that i can enjoy eating "Lechon" without the guilt. On the weekends i could do Cheatdays by drinking beer. Ketodiet is still new here in the Philippines, and alot of my friends are very skeptical about the diet. I will be sharing your blog and your story and hope that i could shed some enlightenment to my peers.
10 pound weight loss , chicken broth works to relieve . But have to be careful of salt intake . I retain fluid, Dr gave script for dieuretic before I even started Keto . I have had the retention problem for a long time , when I took the dieuretic on a normal high carb diet ( I would drop 4 lbs ) but would make me really tired , afraid if I take it now on Keto I will pass out. Any idea what I should try other than the chicken broth
The likely reason they were able to keep the weight off, researchers say, is their resting metabolic rate (RMR) was maintained, and they retained their lean muscle mass. RMR is a measure of metabolism (meaning how your body uses energy), while immobile, and it plays an important role in sustaining weight loss, according to other research, published in August 2016 in the journal Obesity.
In terms of weight loss, you may be interested in trying the ketogenic diet because you’ve heard that it can make a big impact right away. And that’s true. “Ketogenic diets will cause you to lose weight within the first week,” says Mattinson. She explains that your body will first use up all of its glycogen stores (the storage form of carbohydrate). With depleted glycogen, you’ll drop water weight. While it can be motivating to see the number on the scale go down (often dramatically), do keep in mind that most of this is water loss initially.
Ketosis suppresses ghrelin–a hormone that increases hunger,18 while high levels of the ketone beta-hydroxybutyrate may act directly as a satiety signal.19 Exogenous ketosis induced by HVMN Ketone, a ketone ester drink, also decreases appetite and ghrelin.20 If you're looking for a fasting aid, HVMN Ketone is the perfect tool. Our flagship product puts you into nearly immediate ketosis without the need to diet or fast for weeks–try it here.
I have been on a low carb keto diet for more than a year. As T2DM my A1C dropped from 9% to 5.4% & I discontinued meds. All my lipids improved even with ample healthy saturated fat. More than a year now so I wonder why this would be a short term improvement when its obvious that I will not go back to a high A1C and taking 3 diabetes medications including sulphonylureas. It is clear from this article that you lack the necessary experience that would be gained from wholeheartedly trying the diet or monitoring patients doing it properly like me. I would be probably be facing my first amputation if I believed the negativity in your article. So for people with diabetes who may be dissuaded by your article. Ignore it and take back your health by restricting carbs (<25 g a day) or as low as you reasonably can below 130g while being satisfied that you are getting adequate nutrition.
The goal of the ketogenic diet is to put your body into ketosis — a state where your body burns fat instead of carbs for fuel. The diet consists of mostly fat (75% of your daily calories, in fact), with moderate consumption of protein (20%) and very few carbs (<5%).  Without access to glucose from carbs, your body doesn’t have all the highs and lows that lead to hunger pangs, energy crashes, and cravings.  The liver instead must convert fatty acids from your diet into ketones for the body and brain to use as fuel. This keeps blood sugar levels stable. Your body also sheds excess weight — fast. But that doesn’t mean it’s unhealthy or unsustainable — provided you do it the right way.
Cholesterol serves a number of important roles in the body. First of all, cholesterol is a critical structural element in certain tissues such as our brain and nervous system. In fact, it is estimated that around 25% of our cholesterol can be found in the brain. Just to highlight our failed fat philosophy over the years, higher saturated fat intake and high cholesterol levels are associated with better mental function in old age (1)!
The original therapeutic diet for paediatric epilepsy provides just enough protein for body growth and repair, and sufficient calories[Note 1] to maintain the correct weight for age and height. The classic therapeutic ketogenic diet was developed for treatment of paediatric epilepsy in the 1920s and was widely used into the next decade, but its popularity waned with the introduction of effective anticonvulsant medications. This classic ketogenic diet contains a 4:1 ratio by weight of fat to combined protein and carbohydrate. This is achieved by excluding high-carbohydrate foods such as starchy fruits and vegetables, bread, pasta, grains, and sugar, while increasing the consumption of foods high in fat such as nuts, cream, and butter.[1] Most dietary fat is made of molecules called long-chain triglycerides (LCTs). However, medium-chain triglycerides (MCTs)—made from fatty acids with shorter carbon chains than LCTs—are more ketogenic. A variant of the classic diet known as the MCT ketogenic diet uses a form of coconut oil, which is rich in MCTs, to provide around half the calories. As less overall fat is needed in this variant of the diet, a greater proportion of carbohydrate and protein can be consumed, allowing a greater variety of food choices.[4][5]
.. it can be heavy on red meat and other fatty, processed, and salty foods that are notoriously unhealthy. What is unhealthy about red meat. We should know that acrilamides, pyrroles in burnt meat (and veges) from BBQ and over-heated cooking inflames the colon. According to Clark H R, PhD ND an inflamed part allows easy entry for the cancer nucleus and cancer complex, to start and fuel a malignancy at that location.
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]
You’ll need to focus on titrating your insulin. Given the low amount of carbs in the Keto diet, I suggest you take detailed notes on how your blood sugar reacts to protein and fats. That way you can determine how much insulin to take with food. As for your basal, if you consistently go high/low without any bolus on board it might be a good idea to revisit your basal rates

Others consider the keto diet a short-term solution for weight loss. Tyler Drew, a 34-year-old real estate broker from Los Angeles, first read about the diet on Reddit and used it to lose 45 pounds in six months before returning to a traditional diet. While on the keto diet, Drew’s cholesterol levels improved, even though a typical day of eating involved bacon at both breakfast and dinner.
Try to replace all soda and juice consumption with something that has no sugar or only trace amounts of sugar. Switch out fruit juices for low-carb smoothies and tea. Tea comes in a variety of flavors that can help you get through the day if you get tired of water. There are a variety of different smoothies you can make for a meal replacement or as a quick snack as well.
On the other hand, the types of foods you’ll avoid eating on the keto, low-carb food plan are likely the same ones you are, or previously were, accustomed to getting lots of your daily calories from before starting this way of eating. This includes items like fruit, processed foods or drinks high in sugar, those made with any grains or white/wheat flour, conventional dairy products, desserts, and many other high-carb foods (especially those that are sources of “empty calories”).
“As a bariatric surgeon and as a researcher studying the liver for two decades, my research has shown that it is the toxicity of chronic excessive carbohydrate consumption that is the primary cause of obesity and obesity-related co-morbidities. As an obese doctor myself, I was able to lose 90 pounds once I recognized that I had a carbohydrate addiction and so eliminated carbohydrates from my diet. While I have performed more than 8,000 bariatric surgeries, I firmly believe that surgery is only a tool. Obesity and diabetes are not treated by surgery, but rather by the journey to become carbohydrate-free.”

Sleep quality was evaluated by determining sleep propensity and quality by means of the PSS and PSQI, respectively. Overall, participants showed a poor sleep condition with a total score >5 au (Table S1). Thus, a significant improvement in sleepiness (PSS) was observed when comparing the visit of reduced ketosis with baseline, a point that coincided with maximum loss of fat mass (Figure 3B). By contrast, no statistically significant effect was observed on sleep quality and duration (PSQI; Figure 3B). Accordingly, plasma levels of dopamine showed no statistically significant changes (data not shown).


As someone who has hypothyroidism (Hashimoto's), I can confirm that a low-carb, whole foods based diet has not made my condition worse. In fact, it had the opposite effect and my thyroid function has improved. Although I still have to take levothyroxine, I feel better and my antibody values went down. I'm not saying that LCHF eating can reverse hypothyroidism but I'm willing to try and see if it improves my condition even further.
Although the KD has shown promise as an alternative dietary strategy for weight management, it should be approached with caution. Acutely, the KD causes physiological changes which may manifest as the “keto flu,” a set of symptoms which commonly includes headache, nausea, gastrointestinal upset and fatigue. A recent study by Urbain et al. (22) illustrates this point, as they state, “Consistent with other studies, our subjects complained about headache, gastrointestinal symptoms, and general weakness mainly during the 1-week metabolic adaptation phase to a KD.” While these symptoms typically resolve within the first one to two weeks, this may present an unpleasant barrier for many individuals to overcome.
Carbohydrate: Most of what determines how ketogenic a diet is will depend on how much carbohydrate is eaten, as well the individual's metabolism and activity level. A diet of less than 50 or 60 grams of net (effective) carbohydrate per day is generally ketogenic. Some sources say to consume no more than 20 grams of carbohydrates per day, while others cite up to 50 grams, and many recommend no more than 5 percent of calories from carbs. However, athletes and people with healthy metabolisms may be able to eat 100 or more grams of net carbohydrate in a day and maintain a desired level of ketosis. At the same time, an older sedentary person with Type 2 diabetes may have to eat less than 30 net grams to achieve the same level.

First, I want to thank you for all of your dedication and work in providing this site. The difficulty of maintaining a healthy weight is a big problem for so many people. My personal question & issue in staying on Keto is my craving for fresh fruit. This a.m I had a large fresh peach along with my “Bullet Proof” coffee. Have I now sabotaged today’s Keto eating?
Eating out while going keto can be tricky. Planning ahead helps you know where your next snacks and meals will come from, so you aren’t tempted to reach for an easy—high-carb—fix, like fast food. Each week, plan out everything from meals to snacks and if you’re using an app, go ahead and fill in your estimated macronutrients ahead of time. This will help you get an idea of your overall intake, so you can make adjustments to reach your daily goals more easily. Get started by planning to make these 10 keto recipes so good you’ll never know you’re on a diet.
The weight loss program has 5 steps (Supplemental Fig. 1) and adheres to the most recent (2015) European Food Safety Authority guidelines on total carbohydrate intake (17). The first 3 steps consist of a VLCK diet (600 to 800 kcal/d), which is low in carbohydrates [< 50 g (26 to 30 g) per day from vegetables] and lipids (only 10 g of olive oil per day). The amount of high-biological-value proteins range from 0.8 to 1.2 g per kg of ideal body weight to ensure minimal body requirements are met and to prevent the loss of lean mass. In step 1, the patients consumed high-biological-value protein preparations 5 times per day, and vegetables with low glycemic indexes. In step 2, 1 of the protein servings was replaced by a natural protein (e.g., meat or fish) either at lunch or at dinner. In step 3, a second serving of low-fat natural protein replaced the second serving of biological protein. Throughout the ketogenic phases, supplements of vitamins and minerals, such as K, Na, Mg, Ca, and omega-3 fatty acids, were provided in accordance with international recommendations (18). These first 3 steps were maintained until the patient lost the target amount of weight, ideally 80%. Hence, the ketogenic steps were variable in time, depending on the individual and the weight loss target.
Although many proponents recommend this high fat version of Keto for weight loss, it first gained notoriety as a treatment method for Epilepsy. Going as far back as the 1920’s, medical professionals have recommended high fat Keto Diets as a treatment method for difficult to control seizure disorders. However, a diet that includes a high percentage of fats as part of its eating program increases the daily caloric intake. More calories means slower fat loss. Therefore, the higher calorie count is why this Ketogenic Diet type is considered a slower weight loss model for dieters and is why the Ideal Protein Protocol is a more effective Keto Diet for weight loss.
The popular low-carb diets (such as Atkins or Paleo) modify a true keto diet. But they come with the same risks if you overdo it on fats and proteins and lay off the carbs. So why do people follow the diets? "They're everywhere, and people hear anecdotally that they work," McManus says. Theories about short-term low-carb diet success include lower appetite because fat burns slower than carbs. "But again, we don't know about the long term," she says. "And eating a restrictive diet, no matter what the plan, is difficult to sustain. Once you resume a normal diet, the weight will likely return."
The primary outcome was the change from baseline to week 16 in hemoglobin A1c. Changes in all variables were analyzed by the paired t-test or Wilcoxon signed-ranks test, as appropriate. Linear regression analysis was used to examine predictors of change in hemoglobin A1c. A p value of 0.05 or less was considered statistically significant. Statistical analysis was performed using SAS version 8.02 (SAS Institute, Cary, NC).
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.
“I am determined to shatter the chiding “eat less, exercise more” obesity medicine paradigm. Obesity is not a personal failure, but a chronic health condition unfolding in our country and around the world. It is a result of the “carboholic” society we live in. Through a holistic approach, I arm patients with knowledge, tools, and skills to manage their weight as well as their overall health.”

Typically you want to stay away from any brands that use filler ingredients like maltodextrin and dextrose, or high glycemic sweeteners like maltitol. Many low-carb products that claim low net carbs usually use these sugar alcohols. Many candies that are “sugar-free” also use these sweeteners. Avoid them where possible. These specific sweeteners respond in our body in a similar way sugar does.


Though technically a fruit, avocados offer a rich source of heart-healthy monounsaturated fatty acids (MUFAs). They're also packed with fiber to bolster digestive health. One-half of an avocado contains 161 calories, 2 grams (g) of protein, 15 g of fat, 9 g of total carbs, and 7 g of fiber (bringing it to 2 g of net carbs), notes the U.S. Department of Agriculture (USDA).

When the craving for alcohol was evaluated, no statistically significant changes were observed in the MACS scores through the nutritional intervention, taking all patients together (Table S1). However, when the analysis was performed considering the gender of participants in the study, men experienced a significant decrease in the total score through the study (p = 0.047). This decrease was more notable in the maximum ketosis phase as compared with baseline (−15.14; p = 0.047). Moreover, a statistically significant reduction was observed in the lack of inhibition item (−27.19; p = 0.042).
