Some fruits may contain relatively high concentrations of sugar, most are largely water and not particularly calorie-dense. Thus, in absolute terms, even sweet fruits and berries do not represent a significant source of carbohydrates in their natural form, and also typically contain a good deal of fiber which attenuates the absorption of sugar in the gut.
“In my psychiatric practice, the high rate of obesity and metabolic disorders among my patients prompted me to develop an integrative therapeutic response, especially to address frequent patterns of impulsivity/compulsivity, low energy/lethargy, mood instability, mental fog, poor concentration and cognitive deterioration. A real-food, low-carb, healthy-fat, often ketogenic lifestyle, combined with intermittent fasting, stress management, rest, and movement — and appropriate pharmacotherapy as needed — results in improved general health, cognitive function, mood management, and quality of life. Diet Doctor, especially the new Spanish site, is a great tool for my patients.”
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.
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)!
Getting into ketosis is a critical component of the ketogenic diet. You can achieve ketosis by fasting, cutting carbs drastically (typically under 50 grams a day), and/or taking keto supplements, such as BHB (exogenous ketones) and MCT-based meal replacement shakes. After becoming fat-adapted, incorporating intermittent fasting (IF) can help boost weight loss or break weight loss plateaus. The most common method is 16:8 where you go 16 hours without eating, and consume all of your calories during an 8-hour eating window.
Rami co-founded Tasteaholics with Vicky at the start of 2015 to master the art of creating extremely delicious food while researching the truth behind nutrition, dieting and overall health. You can usually find him marketing, coding or coming up with the next crazy idea because he can’t sit still for too long. His favorite book is The 4-Hour Workweek and artist is Infected Mushroom.
There is a lot of information out there on the ketogenic diet, and sometimes that abundance of information can be confusing! Do you need to count macros? What are macros anyway?!? How many carbs can I eat on the Keto Diet? What is keto flu? How do you get enough electrolytes in your Keto Diet to avoid cramps and other keto flu symptoms? How much water should you drink? Is diet soda ok on keto? What foods are keto approved? Will I gain the weight back after keto? Is the Keto Diet safe?
Ketones are a very effective fuel for the brain—often a more efficient fuel than glucose. Your body is like a hybrid car when it comes to fuel. When you run out of carbohydrates to burn for fuel—say you’re fasting before a surgery or a religious holiday—your body seeks an alternative way to get more fuel. (If your body didn’t do this, you would die after a short fast.) So the body kicks into burning fat, which is the metabolic state of ketosis, or “keto.” Technically, your liver takes long-chain and medium-chain fatty acids from your fat tissue, and produces a major ketone called beta-hydroxybutyrate (BHB). BHB provides more energy per unit oxygen used than glucose, which benefits the brain.
During the 1920s and 1930s, when the only anticonvulsant drugs were the sedative bromides (discovered 1857) and phenobarbital (1912), the ketogenic diet was widely used and studied. This changed in 1938 when H. Houston Merritt, Jr. and Tracy Putnam discovered phenytoin (Dilantin), and the focus of research shifted to discovering new drugs. With the introduction of sodium valproate in the 1970s, drugs were available to neurologists that were effective across a broad range of epileptic syndromes and seizure types. The use of the ketogenic diet, by this time restricted to difficult cases such as Lennox–Gastaut syndrome, declined further.
I’ve been following the Keto diet for almost 4 months now. I have lost almost 25 pounds and feel good. I am an active daily walker and have also started doing some strength and conditioning 3-5 days week. I decided to have a physical since I’m being so healthy why not keep up with everything else. All my lab work came back good, and very good except for LDL cholesterol, very high over 200. Immediately the doctor wants to put me on a low dose of medicine. I know I’ve been consuming alot of saturated fats on this diet. I’m confused on what to do now 🙁
This is the first time I heard about Keto diet I need to lose weight because I am a diabetic 2 and high cholesterol and high blood pressure the doctor want me to do but bypass lot of people told me not to everybody was telling me about this new diet keep Keto I want to try it and I made it my goal my weight is 257 on 5 for messaging and I think this is going to be good for me I need a lot of help thank you
If you’re not sure after your initial test, explore other healthy diets such as clean eating and always have in mind that your number 1 goal should be to avoid overly processed foods (keeping this definition fairly broad of course, as we live in the 21st century and have to adapt to modern age as well, where hardly any of us have time to spend 12 hours a day evolving around food production, gathering and cooking).
After increasing water intake and replacing electrolytes, it should relieve most all symptoms of Keto Flu. For an average person that is starting a ketogenic diet, eating 20-30g of net carbs a day, the entire adaptation process will take about 4-5 days. My advice is to cut your carbs to fewer than 15g to ensure that you are well on your way into ketosis within one week. If you are experiencing any more keto flu symptoms, double check your electrolyte intake and adjust.
At 469 pounds I restricted myself to a daily calorie intake between 1k-1.5k a day. Often I would even go down to 800 (not advocating this!). Well, i'm still alive today, down a ton of weight and I restrict myself to about 1.5-2k per day now. As others said, calorie restriction is required to lose, but generally speaking I just go by how I feel. If im full of energy, feeling great and not hitting my calories it's not really a big deal to me.
A well-formulated ketogenic diet, besides limiting carbohydrates, also limits protein intake moderately to less than 1g/lb body weight, unless individuals are performing heavy exercise involving weight training when the protein intake can be increased to 1.5g/lb body weight. This is to prevent the endogenous production of glucose in the body via gluconeogenesis. However, it does not restrict fat or overall daily calories. People on a ketogenic diet initially experience rapid weight loss up to 10 lbs in 2 weeks or less. This diet has a diuretic effect, and some early weight loss is due to water weight loss followed by a fat loss. Interestingly with this diet plan, lean body muscle is largely spared. As a nutritional ketosis state sustains, hunger pangs subside, and an overall reduction in caloric intake helps to further weight loss.

A lot of veggies are carb-heavy—they can’t fit into an ultra-low-carb diet. These include potatoes of course, but also yams, corn, peas, and carrots. The best options for keto dieters include asparagus, bell peppers, Brussels sprouts, leafy greens, and zucchini. “What’s tough for many people to grasp when starting out on a ketogenic diet is that you can’t really eat a lot of [certain] vegetables,” Mancinelli says. “When you’re keeping carbs super low, you have to limit vegetables—which goes counter to everything you know about how to eat healthy and lose weight.”
The insulin theory of obesity, in short, declares that the primary cause of obesity is higher carbohydrate diets because these diets increase insulin secretion more than any other diet. When insulin levels are high, fat storage will increase significantly and “starve” muscles and organs of energy. This causes increased hunger and overeating that results in obesity.
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 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.
a) Why do I need to eat dietary fat during the keto diet if I have plenty of adipose tissue (as is currently the case) that can equally well be used as a source of energy? In your article you simply say that dietary fat is necessary for the keto diet to work, by I can’t see any explanation for that. Eating fat while I already have plenty of it available seems a bit counterintuitive.
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).
Health experts think that the first law is relevant to why we get fat because they say to themselves and then to us, as the The New York Times did, “Those who consume more calories than they expend in energy will gain weight.” This is true. It has to be. To get fatter and heavier, we have to overeat. We have to consume more calories than we expend. That’s a given. But thermodynamics tells us nothing about why this happens, why we consume more calories than we expend. It only says that if we do, we will get heavier, and if we get heavier, then we did.
The first modern study of fasting as a treatment for epilepsy was in France in 1911. Twenty epilepsy patients of all ages were "detoxified" by consuming a low-calorie vegetarian diet, combined with periods of fasting and purging. Two benefited enormously, but most failed to maintain compliance with the imposed restrictions. The diet improved the patients' mental capabilities, in contrast to their medication, potassium bromide, which dulled the mind.
Spices have carbs in them, so make sure you are adding them to your counts. Sea salt is preferred over table salt, as it is usually mixed with powdered dextrose. Most pre-made spice mixes will have sugars added to them, so make sure you read the nutrition label beforehand to make sure you know what’s inside. If you have the choice, never include added sugar into your spice blends or food.
In the early 1900s Frederick Madison Allen developed a highly restrictive short term regime which was described by Walter R. Steiner at the 1916 annual convention of the Connecticut State Medical Society as The Starvation Treatment of Diabetes Mellitus.:176–177 People showing very high urine glucose levels were confined to bed and restricted to an unlimited supply of water, coffee, tea, and clear meat broth until their urine was "sugar free"; this took two to four days but sometimes up to eight.:177 After the person's urine was sugar-free food was re-introduced; first only vegetables with less than 5g of carbohydrate per day, eventually adding fruits and grains to build up to 3g of carbohydrate per kilogram of body weight. Then eggs and meat were added, building up to 1g of protein/kg of body weight per day, then fat was added to the point where the person stopped losing weight or a maximum of 40 calories of fat per kilogram per day was reached. The process was halted if sugar appeared in the person's urine.:177–178 This diet was often administered in a hospital in order to better ensure compliance and safety.:179
It was recently reported that the consumption of diets with low percentages of carbohydrates over a long period of time (>25 years) are associated with higher mortality . This association was mitigated when the substitutions were plant-based . In the current study, patients were exposed to a low carbohydrate intake during less than 90 days and the source of carbohydrate was from vegetables. Moreover, the strong weight loss induced a decrease in the burden of obesity-related disease . Thus, the strength of the current study is reinforced with the consistence of the results with that of previous research, regardless of the strong dietary energy restrictions induced by a VLCK diet.
Can’t you take ketone supplements? No. While it is possible to elevate ketones by taking them, “without the low-carb stimulus, there is no net increase in ketone production, no decrease in insulin, and no net increase in fat oxidation,” says Volek. Don’t trust trainers or “body hackers” who say you can induce ketosis quickly without changing your diet.
“I discovered the ketogenic diet in 2017 and since then I have come to truly believe it is the metabolic and nutritional pathway to overall health. Hippocrates once stated, ‘All disease begins in the gut” and I now truly believe the right food can cure. I am now discouraging patients from undergoing bariatric surgery too soon and advising them to try the keto diet first. Diet Doctor gives people the knowledge they need. It is a place where everyone can go to learn and have fun with this nutritional approach.”
Although many hypotheses have been put forward to explain how the ketogenic diet works, it remains a mystery. Disproven hypotheses include systemic acidosis (high levels of acid in the blood), electrolyte changes and hypoglycaemia (low blood glucose). Although many biochemical changes are known to occur in the brain of a patient on the ketogenic diet, it is not known which of these has an anticonvulsant effect. The lack of understanding in this area is similar to the situation with many anticonvulsant drugs.
Carbohydrate-restricted diets are no more effective than a conventional healthy diet in preventing the onset of type 2 diabetes, but for people with type 2 diabetes they are a viable option for losing weight or helping with glycemic control. There is little evidence that low-carbohydrate dieting is helpful in managing type 1 diabetes. The American Diabetes Association recommends that people with diabetes should adopt a generally healthy diet, rather than a diet focused on carbohydrate or other macronutrients.
As your body breaks through the carb cycle and enters ketosis (where you rely on ketones, instead of carbs, for energy), you may experience fatigue, mental fogginess, even irritability. My "keto flu" only lasted a day, and once I passed it, I never experienced the symptoms again. I even ate a cookie one day during the diet to celebrate my birthday. I certainly came out of ketosis when I ate that treat, but I didn't experience any repercussions for it.
The concept of the glycemic index was developed in 1981 by David Jenkins to account for variances in speed of digestion of different types of carbohydrates. This concept classifies foods according to the rapidity of their effect on blood sugar levels – with fast-digesting simple carbohydrates causing a sharper increase and slower-digesting complex carbohydrates, such as whole grains, a slower one.
Several studies have investigated the potential of LCD or KD on weight loss. For example, Brinkworth et al. (2) compared one year of low-fat (LF) vs. LCD diet in adults with abdominal obesity. Subjects were randomly assigned and diets were isocaloric, with moderate energy restriction. Both groups realized significant weight loss, however, there was no significant difference between groups, suggesting that a LCD was equally effective as a LF diet.
Early studies reported high success rates; in one study in 1925, 60% of patients became seizure-free, and another 35% of patients had a 50% reduction in seizure frequency. These studies generally examined a cohort of patients recently treated by the physician (a retrospective study) and selected patients who had successfully maintained the dietary restrictions. However, these studies are difficult to compare to modern trials. One reason is that these older trials suffered from selection bias, as they excluded patients who were unable to start or maintain the diet and thereby selected from patients who would generate better results. In an attempt to control for this bias, modern study design prefers a prospective cohort (the patients in the study are chosen before therapy begins) in which the results are presented for all patients regardless of whether they started or completed the treatment (known as intent-to-treat analysis).
Several recent studies indicate that a low-carbohydrate diet is effective at improving glycemia. A few studies have shown that in non-diabetic individuals, low-carbohydrate diets were more effective than higher carbohydrate diets at improving fasting serum glucose [13,14] and insulin [6,14-16], and at improving insulin sensitivity as measured by the homeostasis model . One of these studies also included diabetic patients and noted a comparative improvement in hemoglobin A1c after 6 months (low fat diet: 0.0 ± 1.0%; low carbohydrate diet: -0.6 ± 1.2%, p = 0.06)  and 12 months (low fat diet: -0.1 ± 1.6%; low carbohydrate diet: -0.7 ± 1.0%, p = 0.019) duration . In a 5-week crossover feeding study, 8 men with type 2 diabetes had greater improvement in fasting glucose, 24-hour glucose area-under-the-curve (AUC), 24-hour insulin AUC, and glycohemoglobin while on the low-carbohydrate diet than when on a eucaloric low-fat diet . In a 14-day inpatient feeding study, 10 participants with type 2 diabetes experienced improvements in hemoglobin A1c and insulin sensitivity as measured by the euglycemic hyperinsulinemic clamp method . Hemoglobin A1c also improved in an outpatient study of 16 participants who followed a 20% carbohydrate diet for 24 weeks .
Blanket statement: It’s always best to check with your doctor before starting on this regimen. With that said, “the keto diet isn’t recommended for those with liver or kidney disease, or someone with a medical condition, such as a gastrointestinal issue, who can’t metabolize high amounts of dietary fat,” says Sarah Jadin, a Los-Angeles based registered dietitian and founder of Keto Consulting, LLC. If you’ve had your gallbladder removed, the keto diet may be a no-go. Women who are pregnant or breastfeeding and people with certain rare genetic disorders shouldn’t try this diet.
There is little doubt that one key to maintaining a healthy weight is exercise. Cardiovascular workouts burn off energy and improve musculature so the body works more efficiently. However, it can be hard to reduce body fat. This is where a ketogenic diet may help. By reducing daily carbohydrates, the body must look for other sources of energy, and it is forced to use fat reserves. Loading up on carbohydrates right before exercise provides energy when you need it.
As keto grows in popularity, I see more women struggle with it. My anecdotal observation in my medical office and working with people online is that younger men seem to perform best, and better than women of all ages in nutritional ketosis. My female patients, myself included, may have more problems on keto, with their stress hormones (i.e. producing too much cortisol), thyroid function, and may even develop menstrual irregularities. Some women do fine, others may feel worse, suffer from mood issues, and can even gain weight. We are still learning more about why men fare better than women (it may be related to their higher muscle mass). Additionally, there are at least ten genes that may make a person less likely to benefit from keto.
These are all keto related questions that a person looking into the ketogenic diet for the first time will have, and I’ve put together a comprehensive list of answers to these questions and more in my 3 Day Keto Kickstart Plan & Keto frequently asked questions linked to below. If you’re new to keto I recommend starting there, and if you use that Keto Kickstart meal plan as written, I am confident that you will get into ketosis and be losing weight within 3 days of starting. I’m excited for you!!!!
“I have been recommending a low-carbohydrate lifestyle as the foundation of treatment for many medical conditions ever since 1999, when I first became associated with the Atkins’ Center for Complementary Medicine and then became the center’s medical director. I founded my own Center for Balanced health in 2003 to further provide patients with expertise in both traditional and complementary medicine, featuring low-carbohydrate nutrition. The Diet Doctor website is an excellent resource for individuals seeking to adopt a low-carbohydrate lifestyle.”
–These easy low carb blender pancakes will brighten your morning with the sunny taste of lemons and mixed berries. A fabulous gluten-free breakfast treat. My kids all seem to have one track minds, just like their old mum. Turns out that they dream about food as much as I do. Maybe it's a hereditary trait, passed on through the genes of food-obsessed people. Or maybe it's taught when they are really young and impressionable, watching as their mother thinks and schemes and daydreams about her next meal. However it's passed on, my kids all surely have caught that bug.All Day I Dream About Food
I also asked a friend to join me as an accountability partner. She had tried the keto diet before with good success, so having a guide for my myriad questions was a big help. It was also nice to have someone to message at 10 p.m. when I really wanted a cookie so she could commiserate with me. (We agreed the cookie would be delicious, and then ate a cheese stick.)
So I have tried many things to loose weight and nothing worked, including this. This was a while ago. Then I decided I was not going to eat breakfast anymore, because in order to loose weight, you need to be a little bit hungry. So anyways, I have been doing intermittent fasting (eating at noon and dinner 6-8) and the first day was hard for me but I stuck to it with the help of some lemon water. The next 3 days became easier and easier. Today, I realized I was not at all hungry for dinner and was a little scared, because I didn’t want my metabolism to slow down (I’ve had problems in the past) so I googled up what this means. I saw that it was ketosis and was so excited. When I went to check the ketosis strips, it was actually working and I was so so happy. The fact that I was trying so hard with all of these fancy recipes and eating 3 meals a day frustrated me. I do not count my calories or anything else. I do some excercise for about 30 minutes everyday. For those who are struggling, please please please! Try intermittent fasting if the ketogenic diet isn’t working for you.
Lunch: pat dry chicken and cut into cubes. Lightly (!) salt and pepper. Heat a skillet over medium heat, once hot add coconut oil and fry chicken cubes until brown from all sides. Remove chicken, and add crushed garlic, curry paste and fish sauce to pan. Stir until fragrant and remaining oil in pan and curry paste are well combined. Then add coconut milk and whisk until well combined. Simmer and reduce sauce until desired consistency (1-3 minutes). Pour sauce over chicken and sprinkle with sesame seeds. Serve with baby spinach.
In 2017, Drs. Kevin Hall and Juen Guo published what may be the first meta-analysis of controlled feeding studies that compared diets of equal calorie and protein content but differing in carbohydrate and fat content . They made sure only to include studies in which all of the food was provided by the researchers. With these criteria, Drs. Kevin Hall and Juen Guo were able to ensure that confounding variables like the thermic effect of protein and subjects self-reporting their calorie intake wouldn’t muddle up the findings.
Physicians of ancient Greece treated diseases, including epilepsy, by altering their patients' diet. An early treatise in the Hippocratic Corpus, On the Sacred Disease, covers the disease; it dates from c. 400 BC. Its author argued against the prevailing view that epilepsy was supernatural in origin and cure, and proposed that dietary therapy had a rational and physical basis.[Note 3] In the same collection, the author of Epidemics describes the case of a man whose epilepsy is cured as quickly as it had appeared, through complete abstinence of food and drink.[Note 4] The royal physician Erasistratus declared, "One inclining to epilepsy should be made to fast without mercy and be put on short rations."[Note 5] Galen believed an "attenuating diet"[Note 6] might afford a cure in mild cases and be helpful in others.
Urine ketone data were missing in a median of 4 participants (range 0–8) at any given visit. The proportion of participants with a urine ketone reading greater than trace was 1 of 17 participants at baseline, 5 of 17 participants at week 2, and similar frequencies at subsequent visits until week 14 when 2 of 18 participants had readings greater than trace and week 16 when 2 of 21 participants had readings greater than trace. During the study, only 27 of 151 urine ketone measurements were greater than trace, with one participant accounting for all 7 occurrences of the highest urine ketone reading (large160).
Still, there are limitations to the keto diet. The first few weeks on the diet can be rough, and cause what’s known as the keto flu. And some people may experience side effects like thyroid or hormone imbalance, adrenal fatigue, poor sleep quality, and extremely dry eyes. It’s also true that permanent ketosis may not suit everyone. However, there is a way to build a sustainable keto diet which utilizes intermittent, cyclical ketosis as opposed to long-term ketosis…
In part, keto diet weight loss is a real thing because high-fat, low-carb diets can both help diminish hunger and boost weight loss through their hormonal effects. As described above, when we eat very little foods that supply us with carbohydrates, we release less insulin. With lower insulin levels, the body doesn’t store extra energy in the form of fat for later use, and instead is able to reach into existing fat stores for energy.
