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]
Health Impact News has reported on many of the disease reversing results of the ketogenic (high fat-moderate protein-low carb) diet. Now, a new study is looking at the positive effects of gut bacteria among those following a ketogenic diet for epilepsy. Even though Johns Hopkins used a ketogenic diet for curing epilepsy over 80 years ago, when medical drugs did not help epilepsy effectively, mainstream medicine continues to rely on new and expensive toxic drugs for epileptic children. The “cocktail” combinations of pharmaceutical drugs prescribed often worsens childhood epilepsy. Health Impact News previously published a report on how a four year old child with refractory epilepsy (not treatable with pharmaceutical medications), was treated at the Rochester, Minnesota Mayo Clinic using a ketogenic diet. At first, the child was also kept on pharmaceuticals. The results were poor until he was taken off the medications; then he began healing completely. A new Chinese study on pediatric epileptic cases may even draw the attention of mainstream medical professionals, due to the results seen in children's gut microbiota structure when following a high-fat ketogenic diet.
Leftovers will be another thing we will take into consideration. Not only is it easier on you, but why put yourself through the hassle to cook the same food more than once? Breakfast is something I normally do leftover style, where I don’t have to worry about it in the morning and I certainly don’t have to stress about it. Grab some food out the fridge, pre-made for me, and head out the door. It doesn’t get much easier than that, does it?
Dieters and healthy eaters are programmed to get vegetables at every meal in order to reach their daily plant quota, but Mancinelli says the cumulative total can blow through your daily net carbs. “They have vegetables in their breakfast omelet, big salads, snack on celery and carrot sticks, and have big sides of leafy greens in place of rice at dinner,” she says. “The carbs in all those vegetables add up. A few carbs here and there with cheese, nuts, and seeds, and you can really miss the mark for ketosis.” Start smart by cooking with these low-carb vegetables.
Taken together, these results demonstrate a positive effect of LCD/KD on body composition. While KD may not be superior to other dietary strategies aimed at weight reduction, the evidence does suggest that it may be equally effective. Nevertheless, the International Society of Sports Nutritionists, in their Position Stand on the effects of diets on body composition, suggest the KD holds little benefit over higher CHO diets, with one notable exception; KD may enhance appetite control (1).

There is evidence that the quality, rather than the quantity, of carbohydrate in a diet is important for health, and that high-fiber slow-digesting carbohydrate-rich foods are healthful while highly-refined and sugary foods are less so.[4] People choosing diet for health conditions should have their diet tailored to their individual requirements.[19] For people with metabolic conditions, in general a diet with approximately 40-50% high-quality carbohydrate is compatible with what is scientifically established to be a healthy diet.[19]


Research indicates that diets that are high in fat, like the keto diet, do not have a negative impact on cholesterol and triglycerides as long as the carbohydrate intake remains very low. In fact, your cholesterol and triglycerides might actually improve, if you're focusing on eating healthy fats like avocado, olive oil and nuts, not loading up on bacon and burgers.

Wondering how many carb foods you can eat and still be “in ketosis”? The traditional ketogenic diet, created for those with epilepsy consisted of getting about 75 percent of calories from sources of fat (such as oils or fattier cuts of meat), 5 percent from carbohydrates and 20 percent from protein. For most people a less strict version (what I call a “modified keto diet”) can still help promote weight loss in a safe, and often very fast, way.
Ketosis improves certain forms of cellular healing, including mitochondrial biogenesis (the making of new, bigger, and higher energy-producing mitochondria), so that your cells are stronger and have more stamina, particularly when it comes to exercise. For example, some endurance and ultra-endurance athletes believe that their performance improves in nutritional ketosis compared to sugar burning, when they have more fat than carb reserves. But because of the limited data, and available data suggesting that athletes may actually perform worse on nutritional ketosis, I do not currently recommend it for elite athletes.

Available research on the ketogenic diet for weight loss is still limited. Most of the studies so far have had a small number of participants, were short-term (12 weeks or less), and did not include control groups. A ketogenic diet has been shown to provide short-term benefits in some people including weight loss and improvements in total cholesterol, blood sugar, and blood pressure. However, these effects after one year when compared with the effects of conventional weight loss diets are not significantly different. [10]
“As an ophthalmologist, I use a low-carb, high-fat diet approach with intermittent fasting to treat and prevent vision loss associated with diabetic retinopathy in my patients. In addition to my ophthalmology practice, I also treat patients with obesity and metabolic diseases with positive results. I recommend the Diet Doctor website to all my patients so that they get a deep understanding of the low-carb, high-fat approach. It has all the valuable resources they need for a successful ketogenic lifestyle.”
“I’m a family physician and obesity medicine specialist who has been tailoring ketogenic diets for my patients since 2004. I love and live the ketogenic lifestyle. My staff and I have helped reverse hundreds of cases of diabetes and metabolic syndrome over the last 15 years with this simple, effective, long-term lifestyle change. Diet Doctor has been a “go-to” website for thousands of my patients over the years as my patients and I have made this life-saving and health-changing journey.”
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
Boosts energy levels. The sluggishness and lethargy you feel after a heavy carb-filled meal is due to the insulin spike and reactive sharp drop in blood sugars. Eating a high-fat diet provides steady energy and helps you avoid crashes that are associated with eating a high-carb diet. Additionally, since ketones are the brain’s preferred source of energy, a ketogenic diet leaves you feeling more alert and mentally energized without having to supply a steady stream of caloric intake [13].
I have great respect for Harvard Medical School. I notice that they support their readers posting comments and I am most appreciative of the article and all the many thoughtful comments by the readers. The readers seem to have the most expertise here and I hope that the doctor who wrote the article will think long and hard about the comments by readers. After 35 years of clinical practice in mental health, I notice that all issues of emotion involve medical issues, nutrition, and the gut bacteria. I would say that these issues and all of the executive brain functions seem to improve with ketogenic principles. For those that apply it in a flexible and smart manner, it appears to improve every area of their lives. I strongly encourage the author of the article to take one class via The Institute for Functional Medicine. If he is open to more learning he can take more classes and get certified. I’m sure a fine doctor, he will be an even better doctor and personally healthier, if he gets more training. Are we all open to new learning(especially us healthcare providers)?
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.
The opposing viewpoint maintains that calories still count, but the type of food consumed has a trickle-down effect on the amount of energy expended, and what foods the body craves. It takes way more energy to process and store protein than it does carbohydrate or fat–this is called the thermic effect of food. Essentially, one burns more energy digesting protein because it requires more energy for the body to process. In one study, twice as much energy was expended after meals on a high-protein diet versus a high carbohydrate, low-fat diet.1
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.
PATIENTS AND METHODS: Randomized cross-over trial with placebo. The study had no. 2 dietary treatment (DT), conducted in two arms: (1) VLCKD1 in which 50% of protein intake is replaced with synthetic amino acids; (2) VLCKD2 with placebo. The VLCKDs (<800 kcal day-1) were different in term of protein content and quality each arm lasted three weeks (wks). Between the two arms a 3-wks washout period was performed to avoid additive effects on DT to follow. At the baseline, at start and end of each arm, all the subjects were evaluated for their health and nutritional status, by anthropometric analysis, body composition (Dual X-ray Absorptiometry (DXA), Bioimpedentiometry, biochemical evaluation, and Peroxisome Proliferator-Activated Receptor γ (PPAR) γ expression by transcriptomic analysis.
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).
