The modern obesity epidemic appears to be an unprecedented phenomenon, and it coincides with an ever-increased focus on counting calories. Correlation is not causation, so it would obviously be wrong to say that obesity is caused by counting calories. However, counting calories appears to be, at best, an imperfect aid to weight control. So what is really going on?

The popular belief that high-fat diets cause obesity and several other diseases such as coronary heart disease, diabetes, and cancer has not been observed in recent epidemiological studies. Studies carried out in animals that were fed high-fat diets did not show a specific causal relationship between dietary fat and obesity. On the contrary, very-low-carbohydrate and high-fat diets such as the ketogenic diet have shown to beneficial to weight loss.
Food craving refers to an intense desire to consume a specific food. The food cravings questionnaires (FCQs) [24] assess food cravings on a trait and a state level and on a specific food item. The FCQ-trait was derived from a total of 88 statements that were generated using 10 theoretical dimensions of trait food cravings. Participants were asked to indicate how frequently each statement “would be true for you in general” using a 6-point scale that ranged from “Never” or “Not Applicable” to “Always”. The FCQ-state was derived from a total of 60 statements representing seven dimensions of state food cravings. Participants were asked to indicate the extent to which they agreed with each statement “right now, at this very moment” using a Likert scale that ranged from “Strongly Agree” to “Strongly Disagree”.
Because the ketogenic diet alters the body's metabolism, it is a first-line therapy in children with certain congenital metabolic diseases such as pyruvate dehydrogenase (E1) deficiency and glucose transporter 1 deficiency syndrome,[35] which prevent the body from using carbohydrates as fuel, leading to a dependency on ketone bodies. The ketogenic diet is beneficial in treating the seizures and some other symptoms in these diseases and is an absolute indication.[36] However, it is absolutely contraindicated in the treatment of other diseases such as pyruvate carboxylase deficiency, porphyria, and other rare genetic disorders of fat metabolism.[9] Persons with a disorder of fatty acid oxidation are unable to metabolise fatty acids, which replace carbohydrates as the major energy source on the diet. On the ketogenic diet, their bodies would consume their own protein stores for fuel, leading to ketoacidosis, and eventually coma and death.[37]

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]
I am a stage four kidney disease patient. I am also a type one diabetic. I have had diabetes for 37 years. My Internist suggested the Keto diet for me, but there are so many if the foods on the Keto diet that I’m not able to eat because of my kidneys functioning at 22%. How do I reconcile this diet plan to work with my kidney disease? I’m not allowed any dairy, because of my high potassium. Is almond milk ok to drink? I’m not allowed avocados, mushrooms, spinach, tomatoes, greens, (beet or chard). No bacon, or pork. No melons, bananas, oranges, peaches, pears, some apples, pineapple. I can have berries of all kinds. will this still work for me?

Therefore, when you’re following a ketogenic diet plan for beginners, your body is burning fat for energy rather than carbohydrates, so in the process most people lose weight and excess body fat rapidly, even when consuming lots of fat and adequate calories through their daily food intake. Another major benefit of the keto diet is that there’s no need to count calories, feel hungry or attempt to burn loads of calories through hours of intense exercise.


Variations on the Johns Hopkins protocol are common. The initiation can be performed using outpatient clinics rather than requiring a stay in hospital. Often, no initial fast is used (fasting increases the risk of acidosis, hypoglycaemia, and weight loss). Rather than increasing meal sizes over the three-day initiation, some institutions maintain meal size, but alter the ketogenic ratio from 2:1 to 4:1.[9]
(Note that ketosis should not be confused with diabetic ketoacidosis, a dangerous state that occurs primarily in Type 1 and sometimes in Type 2 diabetics, when high levels of ketones build up because there’s not enough insulin to metabolize blood glucose—so the diabetes becomes out of control. This is sometimes due to an infection or other severe stress. But for healthy individuals without Type 1 diabetes, ketones are used as an alternative energy source and rarely poison or acidify the body.)
Initially, 23 participants were recruited into the study, but 3 dropped out voluntarily during the first week of the intervention for reasons unrelated to diet, and therefore were excluded from analysis. The 20 patients who completed the study exhibited the following baseline characteristics: mean age, 47.2 ± 10.2 years; BMI, 35.5 ± 4.4; and waist circumference, 109.4 ± 12.8 cm; 12 (60%) were women (Supplemental Table 1). Other baseline characteristics and their corresponding changes during the study are presented in Table 1.
The keto diet (also known as ketogenic diet, low carb diet and LCHF diet) is a low carbohydrate, high fat diet. Maintaining this diet is a great tool for weight loss. More importantly though, according to an increasing number of studies, it helps reduce risk factors for diabetes, heart diseases, stroke, Alzheimer’s, epilepsy, and more1-6.On the keto diet, your body enters a metabolic state called ketosis. While in ketosis your body is using ketone bodies for energy instead of glucose. Ketone bodies are derived from fat and are a much more stable, steady source of energy than glucose, which is derived from carbohydrates.
“I have been a supporter of a low-carb lifestyle that includes intermittent fasting for myself and my patients for years. I am part of our health systems Medicine Residency program. I teach physicians-in-training and medical staff to utilize low-carb and keto dieting to improve the health of their patients and reduce their need for medications. Diet Doctor is an excellent resource for patients and physicians to help patients help themselves to promote a healthy lifestyle.”
The BHB contained in has been under study for over a decade now. It provides an effective natural remedy to the problem of weight loss and comes at an affordable price. However, some classes of individuals could experience potential negative effects, for example pregnant women. Check with your doctor to get a go ahead before deciding to use the product. To lose weight quickly with , you must use it at the correct intervals and in the appropriate amounts.
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.
The premise of the ketogenic diet for weight loss is that if you deprive the body of glucose—the main source of energy for all cells in the body, which is obtained by eating carbohydrate foods—an alternative fuel called ketones is produced from stored fat (thus, the term “keto”-genic). The brain demands the most glucose in a steady supply, about 120 grams daily, because it cannot store glucose. During fasting, or when very little carbohydrate is eaten, the body first pulls stored glucose from the liver and temporarily breaks down muscle to release glucose. If this continues for 3-4 days and stored glucose is fully depleted, blood levels of a hormone called insulin decrease, and the body begins to use fat as its primary fuel. The liver produces ketone bodies from fat, which can be used in the absence of glucose. [1]
To figure out how many fat grams specifically you want, you would take the total number of calories it takes to maintain your body weight (normally around 14-16 calories per pound of body weight). Subtract your protein calories from that number and then divide by 9 (number of calories per gram of fat). This should give you how many total fat grams you need to eat per day.
Reduced hunger. Many people experience a marked reduction in hunger on a keto diet. This may be caused by an increased ability of the body to be fueled by its fat stores. Many people feel great when they eat just once or twice a day, and may automatically end up doing a form of intermittent fasting. This saves time and money, while also speeding up weight loss.
The most common and relatively minor short-term side effects of ketogenic diet include a collection of symptoms like nausea, vomiting, headache, fatigue, dizziness, insomnia, difficulty in exercise tolerance, and constipation, sometimes referred to as keto flu. These symptoms resolve in a few days to few weeks. Ensuring adequate fluid and electrolyte intake can help counter some of these symptoms. Long-term adverse effects include hepatic steatosis, hypoproteinemia, kidney stones, and vitamin and mineral deficiencies.
“I’ve studied LCHF nutrition for over 20 years for personal health benefits. In my medical practice, it has become integral to reversing many of modern society’s worst medical concerns including metabolic syndrome, obesity, and diabetes. It can be applied safely and effectively for nearly all of my patients and often results in dramatic restoration of good health.”
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.)
As the popularity of the Keto Diet has exploded in recent years the true nature of Ketogenic weight loss has gotten blurred. So what is Keto? Very simply Keto refers to Ketosis, the state into which your body enters when it shifts to burning fat for energy instead of carbohydrates. As carbohydrates and sugar intake is restricted, your body begins to break down its fat stores to use as a source of energy. Therefore, the very basics of a Ketogenic Diet are:
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?

While it may be new to you, the keto diet has actually been around since the 1920’s, when the Mayo Clinic reported its effectiveness for helping epilepsy (that is still the case). Since then, there’s strong evidence that the keto diet helps with weight loss as well as type 2 diabetes, prediabetes, and metabolic syndrome, says Jeff Volek, Ph.D., RD, professor in the department of Human Sciences at The Ohio State University in Columbus, Ohio and co-author of The Art and Science of Low Carbohydrate Living.

Recently, four studies have re-examined the effect of carbohydrate restriction on type 2 diabetes. One outpatient study enrolled 54 participants with type 2 diabetes (out of 132 total participants) and found that hemoglobin A1c improved to a greater degree over one year with a low-carbohydrate diet compared with a low-fat, calorie-restricted diet [5,6]. Another study enrolled 8 men with type 2 diabetes in a 5-week crossover outpatient feeding study that tested similar diets [7]. The participants had greater improvement in glycohemoglobin while on the low-carbohydrate diet than when on a eucaloric low-fat diet. The third study was an inpatient feeding study in 10 participants with type 2 diabetes [8]. After only 14 days, hemoglobin A1c improved from 7.3% to 6.8%. In the fourth study, 16 participants with type 2 diabetes who followed a 20% carbohydrate diet had improvement of hemoglobin A1c from 8.0% to 6.6% over 24 weeks [9]. Only these latter three studies targeted glycemic control as a goal, and two of these were intensely-monitored efficacy studies in which all food was provided to participants for the duration of the study [7,8]. Three of the studies [6,8,9] mentioned that diabetic medications were adjusted but only one of them provided detailed information regarding these adjustments [9]. This information is critical for patients on medication for diabetes who initiate a low-carbohydrate diet because of the potential for adverse effects resulting from hypoglycemia.
For breakfast, we are going to change it up a bit. Here’s where we introduce ketoproof coffee. Now, don’t get me wrong – I know some of you won’t like it. If you’re not a fan of coffee, then try it with tea. If you’re not a fan of the taste (which is very rare), then try making a mixture of the ingredients by themselves and eating it like that. So, why ketoproof coffee?
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.
Essentially, the keto diet for beginners works by “tricking” the body into acting as if its fasting (while reaping intermittent fasting benefits), through a strict elimination of glucose that is found in carbohydrate foods. Today the standard keto diet goes by several different names, including the “low-carbohydrate” or “very-low-carbohydrate ketogenic diet”(LCKD or VLCKD for short).
High levels of triglycerides in the blood are thought to be a sign of poor metabolism. Poor metabolism, or metabolic disorders, are associated with obesity, diabetes, heart disease and cancer. Often times, elevated triglycerides are a byproduct of insulin resistance. In these cases, a ketogenic diet is an excellent strategy to improve those numbers.
Excessive ketone bodies can produce a dangerously toxic level of acid in the blood, called ketoacidosis. During ketoacidosis, the kidneys begin to excrete ketone bodies along with body water in the urine, causing some fluid-related weight loss. Ketoacidosis most often occurs in individuals with type 1 diabetes because they do not produce insulin, a hormone that prevents the overproduction of ketones. However in a few rare cases, ketoacidosis has been reported to occur in nondiabetic individuals following a prolonged very low carbohydrate diet. [4,5]
“As a physician, I see daily the tremendous impact that our pandemic of chronic nutritional disease is having on people and the health care system, despite our best conventional efforts over the last 40 years. I now focus my time and energy on counseling, supporting and guiding patients on the power of real food as medicine. Using the core principles of low-carb, high-fat eating and intermittent fasting, we see great improvements in diabetes, obesity, metabolic syndrome, polycystic ovary syndrome, NAFLD and many more chronic diseases. Diet Doctor is a great resource for my patients to help them in their journey.”
We would like to thank A. Menarini Diagnostics Spain for providing, free of charge, the portable ketone meters for all the patients. We acknowledge the PronoKal Group® for providing the diet for all the patients free of charge and for support of the study. The funding source was not involved in the study design, recruitment of patients, study interventions, data collection, or interpretation of the results. The Pronokal personnel (I.S.) revised the final version of the manuscript, without intervention in the analysis of data, statistical evaluation and final interpretation of the results of this study.

“I recommend the low-carb diet and other lifestyle changes to reverse obesity, diabetes, hypertension and PCOS at our health wellness centre. The prevalence of food and lifestyle-related diseases in a developing country like Tanzania is increasing at an alarming rate. Evidence-based scientific approaches combined with low carb have been my basic tools to reverse diabetes, hypertension, obesity and many other metabolic diseases.”
One of the primary culprits of chronic inflammation in our society is a poor diet full of sugars and processed vegetable oils. In fact, blood sugar and measurements of insulin resistance are a much more accurate predictor of heart disease risk. I often look at values such as fasting glucose, HbA1c, and fasting insulin as a means of determining the inflammatory state of someone’s body.
At the core of the classic keto diet is severely restricting intake of all or most foods with sugar and starch (carbohydrates). These foods are broken down into sugar (insulin and glucose) in our blood once we eat them, and if these levels become too high, extra calories are much more easily stored as body fat and results in unwanted weight gain. However, when glucose levels are cut off due to low-carb intake, the body starts to burn fat instead and produces ketones that can be measured in the blood (using urine strips, for example).
“One of the best meal planning tips I’ve ever received is to structure breakfast and lunch so that you don’t have to think too much about it,” says Emily Bartlett, co-founder of Real Plans. “If you’re OK with repetition, it’s ideal to have a simple selection of recipes for breakfast—including some that can be taken on the go. For lunch, go ahead and use your leftovers with a fresh green salad, and be sure to include a dressing that you really love.” Before you make your keto diet menu, check out the 13 things doctors want you to know about the keto diet.
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…
White sugar, honey, and most traditional sugars are out when you’re eating keto because of the high carb counts. While many artificial sweeteners deliver sweetness sans a single carb, that doesn’t mean you should eat them, Crandall says. “We have demonized sugar—rightly so—for causing unneeded insulin spikes,” Crandall says, but “many artificial sweeteners do the exact same thing.” One study found that eating artificial sweeteners may increase cravings—especially for sweet things. This can stymie your weight-loss intentions. Discover how one woman totally kicked her sugar habit by trying the keto diet.
