The nutritional intervention was based on a commercial weight-loss program (PNK method®), as was described elsewhere [4]. Briefly, the intervention included an evaluation by the specialist physician conducting the study, an assessment by an expert dietician, and exercise recommendations. This method is based on high-biological-value protein preparations obtained from cow’s milk, soy, avian eggs, green peas, and cereals. Each protein preparation contained 15 g protein, 4 g carbohydrates, 3 g fat, and 50 mg docohexaenoic acid and provided 90–100 kcal.
Thankyou for the breakdown! I’m quite excited to get started. I’m a T1 newly diagnosed (6m) and the hospital educator had me eating 30gm Carbs per meal which saw me a) Nearly vomit every meal as it was too much food b) gain a ridiculous amount of weight! (never really been a big carb eater, but my issue was not eating frequently!) (15+kg gained!) so bring on 2019 with a better relationship with food and a better relationship with myself, knowing how and what works with for my body. blessings xx😘
An important strength of this study was the use of 3 different techniques for determining body composition in different settings, i.e., obesity and no ketosis, marked reduction in body weight with high ketosis, and finally, substantial reduction in body weight without ketosis. The tight control of adherence by daily measurement of B-OHB is another relevant strength of this work. A potential limitation of our study could be the sample size; however, because each subject underwent 4 evaluations, enabling each individual subject’s own results to be compared, this adds statistical power to the study and a real difference between the experimental points.
Yes, you'll lose weight but only because you're consuming fewer calories. There's no real magic to the keto diet. The weight-loss equation remains the same: You lose weight when you consume fewer calories than you use each day. You're not burning more fat than other diets, or at a faster rate. On the keto diet, you eat high-fat meals with protein, which keeps you feeling full for longer and cuts down on your overall eating throughout the day.
It’s estimated that over 50% of people are deficient in Vitamin D worldwide[*]. Although Vitamin D doesn’t play a major role in whether or not you are in ketosis, it is responsible for regulating immunity, inflammation, hormones and helping with electrolyte absorption[*][*] — all factors important for weight loss and overall health. Additionally, studies support the direct benefits of vitamin D for weight loss[*][*][*]. You can check your Vitamin D levels with a simple blood test and then supplement accordingly. When supplementing, choose Vitamin D3 as it is the form that’s best absorbed by your body[*][*].
When ketone bodies accumulate in the blood, this is called ketosis. Healthy individuals naturally experience mild ketosis during periods of fasting (e.g., sleeping overnight) and very strenuous exercise. Proponents of the ketogenic diet state that if the diet is carefully followed, blood levels of ketones should not reach a harmful level (known as “ketoacidosis”) as the brain will use ketones for fuel, and healthy individuals will typically produce enough insulin to prevent excessive ketones from forming. [2] How soon ketosis happens and the number of ketone bodies that accumulate in the blood is variable from person to person and depends on factors such as body fat percentage and resting metabolic rate. [3]
You’ve heard this proclamation even before starting keto diet: You need plenty of water each day for your health. That’s especially true with the keto diet. Without carbs, your body won’t store as much water. Anything you drink passes right through—you can expect to urinate frequently. “Starchy foods have more water retention,” Dr. Marvasti says. “When you avoid these types of foods, you need to make sure you are compensating by drinking enough water.” These 7 clever ways to stay hydrated can help.
One area where food tracking can be especially helpful, though, is ensuring that you're hitting the right ratios of macronutrients—protein, carbs, and fat. "The most researched version of the ketogenic diet derives 70 percent of calories from healthy fats, 20 percent from protein, and only 10 percent from carbs," explains Charles Passler, D.C., nutritionist, and founder of Pure Change. "In the ideal world, each keto meal and snack should have that same (70/20/10) ratio of macronutrients, but studies have shown that you'll still achieve great results even if each meal varies slightly from that ratio, just as long as you don't exceed 50 grams per day of carbs, or eat those carbs in one sitting," says Passler. In order to achieve these ratios without a preset meal plan from a dietitian or doctor, some food tracking is probably going to be necessary. But once you get the hang of things, you may not need it anymore.

A Cochrane systematic review in 2018 found and analysed eleven randomized controlled trials of ketogenic diet in people with epilepsy for whom drugs failed to control their seizures.[2] Six of the trials compared a group assigned to a ketogenic diet with a group not assigned to one. The other trials compared types of diets or ways of introducing them to make them more tolerable.[2] In the largest trial of the ketogenic diet with a non-diet control[16], nearly 38% of the children and young people had half or fewer seizures with the diet compared 6% with the group not assigned to the diet. Two large trials of the Modified Atkins Diet compared to a non-diet control had similar results, with over 50% of children having half or fewer seizures with the diet compared to around 10% in the control group.[2]

Note that women with thyroid or adrenal dysregulation require more healthy carbs. In general, the optimal carbohydrate level for you can vary over the years, such as when you’re more active physically or breastfeeding or stressed. Chronically eating low carb may increase your risk of mood disorders, so I urge caution and that you work with your healthcare professional. To be safe, eat the most carbs that you can tolerate while staying in ketosis.
An extreme form of low-carbohydrate diet – the ketogenic diet – is established as a medical diet for treating epilepsy.[14] Through celebrity endorsement it has become a popular weight-loss fad diet, but there is no evidence of any distinctive benefit for this purpose, and it had a number of side effects.[14] The British Dietetic Association named it one of the "top 5 worst celeb diets to avoid in 2018".[14]
Although fat is the centerpiece of any keto diet, that doesn't mean you should be subsisting on butter-topped steaks, says Kristen Mancinelli, RD, author of The Ketogenic Diet. “A big misconception is that you should just put meat at the center of your plate and add more fat on top,” she says. You also shouldn't be relying on fatty meats to hit your fat quota, she adds.
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.

But your heart health might depend on what you actually eat. Research published in the New England Journal of Medicine suggests that low-carb diets based mostly on plant sources of fat and protein (like avocados or nuts) can lower heart disease risk by 30 percent. But those benefits didn’t hold for people who ate mostly animal-based proteins and fats. (Think: bacon, butter, and steak.)
During this study, the patients followed the different steps of the method until they reached the target weight or up to a maximum of 4 months of follow-up, although patients remained under medical supervision for the following months. Patients visited the research team every 15 ± 2 days to control adherence and evaluate potential side effects. Complete anthropometric, body composition, biochemical and phycological assessments were performed at four of the visits which were made according to the evolution of each patient through the steps of ketosis and weight loss: Visit 1 (baseline), visit 2 (maximum ketosis), visit 3 (reduced ketosis) and visit 4 (Endpoint).
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%.
“I recommend low-carbohydrate, high-fat (ketogenic) diets to almost all my patients to improve their quality of life. The LCHF diet reduces inflammation, promotes weight loss, and improves blood biomarkers without prescription agents. The result is improved sleep, sharper mental clarity, more energy throughout the day, and healthier relationships to food. Most patients suffer “fat phobia” but fat does not make you fat! Sugar does! We teach patients to eat lots of healthy fats and cycle in and out of ketosis. We refer everyone to Diet Doctor as a great resource, especially for the carb contents of various food and drinks.”
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.
If you think about it, one of the diets that follow these principles is the low-carb ketogenic diet. It focuses on highly-satiating foods like meat and low-carb vegetables while cutting out all processed, carb-ridden, and highly-palatable foods. By eating in this way, most people experience tremendous amounts of fat loss — not because insulin levels dropped or the body got a metabolic advantage from burning fat, but because keto dieters tend to eat significantly fewer calories than before without realizing it. 

Similar to our results, three studies noted that diabetes medications were reduced in some participants[6,8,9], although details were provided in only one study. We also discontinued diuretic medications during diet initiation because of concern for additional diuresis incurred by the diet. This concern was based on the theoretical effects of the diet [17], observed effects of the diet on body water by bioelectric impedance [18], and practical experience with the diet [19]. Until we learn more about using low carbohydrate diets, medical monitoring for hypoglycemia, dehydration, and electrolyte abnormalities is imperative in patients taking diabetes or diuretic medications.
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.
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? 

Thyroid health and longevity. Along with balancing sex hormones, a ketogenic lifestyle has a positive effect on thyroid hormones as well. A very low-carb diet tends to drive down T3, the main active thyroid hormone. Higher T3 levels make your cells use more energy (hyperthyroidism), which can increase free-radical production. Many scientists believe that lower levels of T3 actually increase lifespan by conserving energy and decreasing free-radical production. A ketogenic lifestyle is positively correlated with improved thyroid health and overall longevity [15].


“I am a physician with type 1 diabetes. I have been using a low-carb, ketogenic diet to treat my own diabetes for the past 16 years. Evidence shows that low-carb diets are safe and effective. With the potential to reverse type 2 diabetes, control type 1 diabetes and even stop, slow down, or reverse complications, a low-carb diet can be life changing. Diet Doctor provides the most accurate and relevant materials for a healthy, easy and fun low-carb experience.”
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.”
Keto diet saved me mentally, I thought I’d never get out of depression. Keto also saved me physically as well. I don’t have the extreme soreness or laziness. I would not go out for weeks, now I am out everyday. I was sick al the time but now I don’t feel like I am dying. I have so much HOPE now and look forward to everyday. It has affected me in a very positive way. Not to mention increasing my confidence. I am never hungry all the time. I love my way of eating and not having all the sugar and carbs in my body.

“As a reproductive endocrinologist, I have been studying nutrition and fertility for over 15 years. I advise all my patients, both women and men, to adopt a low-carb ketogenic diet both prior to pregnancy to improve their fertility and during pregnancy to improve fetal and maternal health. This way of eating has been shown repeatedly in my practice to improve all measures of health for women and men. We refer all our patients to Diet Doctor which in our opinion is the best online resource for our patients to find all the information, recipes and meal plans they need to be successful.”

Collagen is a type of protein that has been shown to suppress appetite[*], provide fullness compared to other proteins like whey, casein, or soy[*], help retain muscle mass[*] and even help to reduce the appearance of cellulite due to it’s ability to improve skin elasticity and thickness[*]. Refer to this article for more information on the benefits of collagen and the best way to supplement it in your diet.
In general, people on ketogenic diets tend to consume a lot of foods high in monounsaturated and saturated fats such as olive oil, butter (often butter from grass-fed cows is recommended), avocado, and cheeses. The high oleic types of safflower and sunflower oils (but not the regular forms of these oils) are also good choices, as they are high in monounsaturated fats and low in polyunsaturated fats.
The liquid diets involved with VLCDs often bring on ketosis, a condition that involves a buildup of ketone bodies in the blood as well as urine. Ketones are a byproduct that is created when your body has to switch to fat as an energy source. It means your store of glycogen, or carbohydrates, has been depleted. One of the consequences of ketosis is a loss of appetite, which helps make it easier to follow a VLCD. Ketosis also causes you to shed excessive amounts of sodium, potassium and water, which can cause dehydration, sluggishness, constipation and gas. However, your body can adjust to changes in your electrolytes.
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).

On a high-fat ketogenic diet, you can easily eat 3,000 calories or more daily with high-calorie foods like cheese and nuts. Sure, your body will shift into ketosis on a high-fat diet, but eating too many calories means your body will utilize dietary fat instead of body fat. A food journal can help you pinpoint high-calorie foods that might sabotage your weight loss. You don't need to be on an old Atkins diet plan to lose weight the keto way.


There are so many tricks, shortcuts, and gimmicks out there on achieving optimal ketosis – I’d suggest you don’t bother with any of that. Optimal ketosis can be accomplished through dietary nutrition alone (aka just eating food). You shouldn’t need a magic pill to do it. Just stay strict, remain vigilant, and be focused on recording what you eat (to make sure your carb and protein intake are correct).
Next month I celebrate one year since I started Keto. I don't even know who the person is in the yellow top. Feels like a lifetime ago. Love this journey I've been on and even though I'm not 100% Keto all the time, love the Keto way! #keto #ketoweightloss #ketosuccess #ketosis #ketofam #ketodiet #ketogenicdiet #ketogeniclife #ketogenicliving #weightloss #weightlossjourney #weightlosstransformation #weightlossinspo #ketogenicweightloss #lowcarb #lowcarbweightloss

There is nothing inherently difficult about following a ketogenic diet. We have many patients who do this very easily over many years. The metabolic benefits significantly outway any perceived challenges from limiting particular food types. Uptake would be far more widespread if nutrition professionals left their predujical opinions of SFA’s behind. Finally, given the expertise in Ketogenic Diets at Harvard, Dr David Ludwig, for one springs to mind, I am surprised the author did not avail themselves of the local expertise.
“I first began recommending a low-carbohydrate approach to diet and lifestyle in 2017 after discovering personal success with this way of eating. Since then, I’ve helped many patients adopt a LCHF diet and seen substantial clinical improvements — particularly with insulin resistance and diabetes — with this approach. Eating whole, nutritious food is good for everyone and results in the remission of disease and restoration of both physical and mental health.”

“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.”


Hi Cyn, The numbers are general guidelines but will vary depending on many factors, such as activity level, insulin resistance, weight and more. There is no single magic number, just conventional recommendations that are a good starting point. I will have a macro calculator coming soon that will help determine what is best for each person, but even then it’s an approximation. The only way to know for sure is to test. If keto is your goal, it’s usually best to start lower and then see if you can stay in ketosis when increasing.

The average daily goal for keto is 20 grams of net carbs. Net carbs are the total carbs in a given serving of food, minus the carbohydrates that are supplied by fiber. You’ll find carb grams quickly add up, even when you’re choosing the best low-carb foods, like spinach and avocado. Keeping your body in a quasi-keto state can be hard on you, warns Santo: “This will leave you feeling sluggish, foggy, and discouraged,” he says. “It will most likely cause a weight plateau, and maybe even weight gain.” Here’s what it’s really like to be on a keto diet.

Anecdotally speaking, people do lose weight on the keto diet. Heather Wharton, a 35-year-old business relationship manager from Tampa, Florida, lost 140 pounds since starting the keto diet in January 2016: “I plan on being on the keto diet for the rest of my life,” says Wharton. “My husband and I consider ourselves to be food addicts, and the keto diet is what we use as a form of abstinence from trigger foods that have sugar and other carbohydrates." A typical day of eating for Wharton includes coffee with a protein supplement, a cup of unsweetened cashew milk, cauliflower rice with ground turkey and liquid aminos (a carb-free substitute for soy sauce), spinach, six slices of turkey bacon, six eggs, and a little salsa.
“As a nephrologist, I have seen many patients with end-stage kidney failure resulting from diabetes and obesity. I decided to switch my career towards wellness, integrative medicine and obesity management. I now provide guidance for ketogenic and low-carb diets along with fasting to all patients in my clinic and via telehealth consultations. It is very rewarding to see their health improve and their medications reduced or eliminated. I refer all my patients to Diet Doctor on the first visit and I teach them also to use the recipes on the site. Thank you for providing an unbiased educational platform!”

Eliminating several food groups and the potential for unpleasant symptoms may make compliance difficult. An emphasis on foods high in saturated fat also counters recommendations from the Dietary Guidelines for Americans and the American Heart Association and may have adverse effects on blood LDL cholesterol. However, it is possible to modify the diet to emphasize foods low in saturated fat such as olive oil, avocado, nuts, seeds, and fatty fish.

While in ketosis, your body effectively uses fat for fuel. In general, the daily intake of net carbs required to enter ketosis could vary from 20 to 100 grams per day. Most people, who have experienced ketosis, claim to have reached that state at about 20-50 grams of net carbs per day. I'd suggest you start at 20-30 grams and see how you can adjust it for your needs.
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.
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).
Katherine Arvesen, RDN, who in private practice in Plano, Texas, also notes that the study was not randomized and controlled, which is the gold standard for medical research to minimize error and bias. In this study, the patients were their own controls, meaning their results were compared with their own baseline (starting) measurements, not with the results of a control group.
This work demonstrates that a VLCK diet following the PNK method induces a severe body weight reduction concomitantly with a decrease in food craving and improvements in psychological well-being measured by physical activity, sleep quality, female sexual function, and quality of life scores. The effect in food craving and psychological well-being could be relevant factors to guarantee the success of this kind of nutritional treatment. Moreover, this effect is added to the beneficial effects previously observed regarding body composition, energy metabolism, and biochemical parameters [4,7,18,35].
“As a physician who developed type 1 diabetes in 1998 at the age of 38, I struggled to manage my blood sugar with conventional medical advice. I met Dr. Andreas Eenfeldt at a medical meeting in 2012 and have used Diet Doctor as an excellent source of information for both myself and my patients ever since. The low-carb diet resulted in a marked improvement in my blood sugar control and my entire outlook on life. I provide online coaching to people with diabetes who need individualized attention.”

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?


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.
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.
Basically, carbohydrates are the primary source of energy production in body tissues. When the body is deprived of carbohydrates due to reducing intake to less than 50g per day, insulin secretion is significantly reduced and the body enters a catabolic state. Glycogen stores deplete, forcing the body to go through certain metabolic changes. Two metabolic processes come into action when there is low carbohydrate availability in body tissues: gluconeogenesis and ketogenesis.[4][5]
“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!”

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).
