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?
The beauty of The 3-Week Ketogenic Diet is that it's completely opposite of the majority of "lose-weight quick" weight loss scams. The 3-Week Ketogenic Diet focuses on FAT LOSS, not weight loss (the difference is explained in the Program Guide). You'll be eating anti-inflammatory foods that promote a healthy, a fast metabolism, and stimulates fat-burning hormones. You'll lose a lot of weight and inches in a short period of time and this time...you'll keep it off.
A ketogenic diet may be an option for some people who have had difficulty losing weight with other methods.  The exact ratio of fat, carbohydrate, and protein that is needed to achieve health benefits will vary among individuals due to their genetic makeup and body composition. Therefore, if one chooses to start a ketogenic diet, it is recommended to consult with one’s physician and a dietitian to closely monitor any biochemical changes after starting the regimen, and to create a meal plan that is tailored to one’s existing health conditions and to prevent nutritional deficiencies or other health complications. A dietitian may also provide guidance on reintroducing carbohydrates once weight loss is achieved.
“I recommend low-carb nutrition for the majority of my patients and clients. And I send them all to Diet Doctor for the best recipes, instructional videos and written guides for everything someone needs to get started and to thrive on a low-carb lifestyle. Diet Doctor doesn’t have anything to sell you; its only goal is to provide you with the highest quality, evidence-based information to help you improve your life. That is hard to find in today’s ad-driven and product-driven internet. In fact, I loved Diet Doctor so much, I decide to work for them hosting their podcast!”

The ketogenic diet is not a benign, holistic, or natural treatment for epilepsy; as with any serious medical therapy, complications may result.[28] These are generally less severe and less frequent than with anticonvulsant medication or surgery.[28] Common but easily treatable short-term side effects include constipation, low-grade acidosis, and hypoglycaemia if an initial fast is undertaken. Raised levels of lipids in the blood affect up to 60% of children[38] and cholesterol levels may increase by around 30%.[28] This can be treated by changes to the fat content of the diet, such as from saturated fats towards polyunsaturated fats, and if persistent, by lowering the ketogenic ratio.[38] Supplements are necessary to counter the dietary deficiency of many micronutrients.[18]

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.

We in Broxtowe constituency have to put up with this undemocratic politician daily. To call her duplicitous is a huge understatement. ..... And try getting a reply from her over other issues. All you get is a cut and paste general reply. She's clearly far too busy doing the rounds of radio, TV and other interviews for which she presumably takes fees rather than doing the job she's paid for as an MP.
Metabolic flexibility: The ketogenic diet is not metabolically flexible. On the diet, your body adapts to using fats for fuel, which, in turn, means it is no longer adapted to using carbs efficiently. People have the tendency to follow the diet strictly for a few months, get the results they want, and then switch right back to a carb-happy diet.  If you introduce a lot of carbs when your body isn’t adjusted to handling them, you may gain back all of the fat you lost, if not more. It's often the case that many people gain fat after reintroducing carbs because their calories inadvertently go up or they get nutrient timing wrong. When transitioning out of keto, re-introduce carbs carefully to ensure your suffering wasn’t all for nought.
Total body composition was first measured by iDXA (GE Healthcare Lunar, Madison, WI). Daily quality control scans were acquired during the study period. No hardware or software changes were made during the course of the trial. Subjects were scanned using standard imaging and positioning protocols, while wearing only light clothing. For the current study, bone mineral density, lean body mass, and FM values, which are directly measured by the GE Lunar Body Composition Software (GE Healthcare), were used. Some derivative values, such as bone mineral content, regional lean mass, ALM, FFM, and FM percentage (FM%), as well as android and gynoid fat (%), were also calculated. The android/gynoid ratio was automatically generated and analyzed using enCORE software, version 13.6 (GE Healthcare). For measuring android fat, a region of interest was automatically defined as the caudal limit placed at the top of the iliac crest, and its high was set to 20% of the distance from the top of the iliac crest to the base of the skull to define the cephalic limit of abdominal subcutaneous adipose tissue. The scanner was calibrated daily against the calibration block supplied by the manufacturer.

“A lower-carbohydrate diet and lifestyle has not only changed my personal health for the better, but also the health of my family and my patients. The low-carb ketogenic lifestyle has also transformed my medical practice from a traditional sick-care office to an Integrative Wellness practice that focuses on improving people’s health and preventing illness. I enjoy going into work every day as I now feel I am truly preventing chronic diseases from taking root via proper nutritional counseling. I send virtually all my patients to Diet Doctor for help getting started on their own low-carb journey.”
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.
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.

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.
But it has its share of critics as well. The keto diet is sometimes referred to as “the bacon and butter diet” because it calls for 75% of daily calories to come from fat. Keto followers are gobbling up bacon, steak, sausage, and chicken (skin and all). They’re adding butter to their morning coffee. They’re drowning their salads with ranch dressing.
Long-term use of the ketogenic diet in children increases the risk of slowed or stunted growth, bone fractures, and kidney stones.[18] The diet reduces levels of insulin-like growth factor 1, which is important for childhood growth. Like many anticonvulsant drugs, the ketogenic diet has an adverse effect on bone health. Many factors may be involved such as acidosis and suppressed growth hormone.[38] About one in 20 children on the ketogenic diet develop kidney stones (compared with one in several thousand for the general population). A class of anticonvulsants known as carbonic anhydrase inhibitors (topiramate, zonisamide) are known to increase the risk of kidney stones, but the combination of these anticonvulsants and the ketogenic diet does not appear to elevate the risk above that of the diet alone.[39] The stones are treatable and do not justify discontinuation of the diet.[39] Johns Hopkins Hospital now gives oral potassium citrate supplements to all ketogenic diet patients, resulting in one-seventh of the incidence of kidney stones.[40] However, this empiric usage has not been tested in a prospective controlled trial.[9] Kidney stone formation (nephrolithiasis) is associated with the diet for four reasons:[39]

The inclusion criteria were age 18 to 65 years, body mass index (BMI) ≥ 30 kg/m2, stable body weight in the previous 3 months, a desire to lose weight, and a history of failed dietary efforts. The main exclusion criteria were thyroid alteration, diabetes mellitus, obesity induced by other endocrine disorders or by drugs, and participation in any active weight-loss program in the previous 3 months. In addition, those patients with previous bariatric surgery, known or suspected abuse of narcotics or alcohol, severe depression or any other psychiatric disease, severe hepatic insufficiency, any type of renal insufficiency or gouts episodes, nephrolithiasis, neoplasia, previous events of cardiovascular or cerebrovascular disease, uncontrolled hypertension, orthostatic hypotension, and hydroelectrolytic or electrocardiographic alterations were excluded. Females who were pregnant, breastfeeding, or intending to become pregnant and those with child-bearing potential and not using adequate contraceptive methods were also excluded. Apart from obesity and metabolic syndrome, participants were generally healthy individuals. Under these conditions, 20 obese patients were included in this study.
Dr. Stephen Phinney, who has been doing research on ketogenic diets since the 1980s, has observed that people don't do as well when they are consuming a lot of these oils (mayonnaise and salad dressings are a common source). This could be because omega-6 fats can be inflammatory, especially in large amounts, or some other factor. In his studies, people didn't feel as well or perform as well athletically.
I’ve used the Atkins diet for almost 3 months now. Averaging 3/4 pounds a week loss. Never hungry and sometimes replace a meal with an Atkins shake (I make my own: One shake over ice, add 1/4 cup of heavy cream, one Splenda pack, stir and enjoy. Tastes like a milkshake! Carbs, 1 or 2. SECRET TO THE ATKINs DIET- YOU MUST drink your water! I also trim most of the fat off my meat and seldom eat bacon. Dairy – low/0 carb cheeses, mayo, some sour cream. I make wonderful veggie quiche (no crust) and a bread pudding quiche that everyone steals! Salad dressing is a breeze with mayo, mustard and Splenda. Zero carb (maybe 1/2 gram) & tastes like honey mustard. And, boy, if you could have one of my egg-batter, ham & cheese sandwiches. . .it’s to die for! I keep a bowl of steamed veggies in the fridge. Dipping in dressing makes a great snack. Atkin’s bars are a delicious way to get your sweets.I cut them up and nibble during the day. They also sell low carb breads now, very expensive, but the cost makes up for what I’m NOT buying to eat. Weight keeps dropping off, I feel great AND, every time I think of having a bowl of ice cream, I run to the closet and look at all the pretty clothes that soon I can wear again. Then I ‘strip’ and look in the mirror! Yikes! YOU TELL ME WHAT’S BETTER: being ‘fat’ or looking great? I was a model before gaining weight (due mostly to illness) and every pound I lose is totally worth it. I DON’T CARE WHAT ‘THEY’ SAY . . . ‘fat’ isn’t pretty, or acceptable. It’s your road to an early death and every organ in your body is suffering and struggling everyday. Lastly –

“I have been working as an internal medicine doctor and diabetologist for over 20 years, focusing on gestational diabetes mellitus (GDM), and also teaching future doctors and nutritionists. In 2016, we corrected our official dietary guidelines for GDM, removing the minimum recommended intake of carbohydrates and setting a maximum at 200 grams a day, with low-carbohydrate diets as an option. I would like to thank GDM dietitian Lily Nichols, Dr. Andreas Eenfeldt at Diet Doctor and the entire LCHF community for improving outcomes of Czech women with GDM and other patients with type 1 and type 2 diabetes or metabolic syndrome.”
I have been on a keto diet for over a year. I lost 60 pounds and got off five different meds and a shot in the stomach for the last 25 years. Fasting sugar under 150 was considered good control. A1C was usually around 7. Now sugars are rarely over 80 and A1C is 5.4. THEN I PLATEAUED AND EVEN GAINED BACK 10 pounds. Little did I know I have been shooting myself in the foot. It didn't help that I quit a job that required seven miles of vigorous walking each day, but I begin my day with a big glass of half and half. I didn't realize I was adding 16-20g hidden carbs over my 25g allotment. I am switching to making my own with heavy whip cream and almond milk. That drops carb count to 6.4g per cup.
A typical keto diet is comprised of 80 percent fat, 15 percent protein, and a mere 5 percent of calories from carbohydrates. If you consume 2,000 calories a day, that means just 100 of them are coming from carbs—including healthy carbs like fruits and vegetables. When you eat this way, it triggers ketosis, which means your body has burned through all its carbs and needs to begin burning fat for energy.
Loading up on fat lowers your levels of insulin. Insulin is a hormone that tells your body to store energy, either as fat or glucose.[4][5] The more insulin your body releases, the more fat that gets stored. Insulin also blocks leptin, the hormone that sends a signal to your brain when you’ve eaten enough to meet your energy needs.[6] That means when you eat carb-heavy foods, you’re at risk of overeating and won’t get that full feeling before reaching for a second helping of potatoes.
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?
You're using it for a particular, short-term period.The meal substitute diet can function so quick and so well that you might decide to keep on following it for a longer while. You've acquired the flavor and habit of consuming the yummy meal substitute products that you think you'll stick to the program for a vague period. However, you need to understand that enduring high-calorie deficit in your system may not be good on an extended basis. Take advantage of the diet only as a boost to significant weight reduction or to be a procedure for a huge occasion arriving soon or under strict doctors monitoring.
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).

Previous studies have shown that ketogenic diets preferably reduce the total FM in obese patients (10–13). However, the precise distribution of these losses has not been determined. In this study we confirmed that the diet reduces total FM and specifically visceral adipose tissue, which has a greater impact in predicting cardiometabolic complications associated with obesity than does the total volume of body adiposity (2, 31).


Despite continuous advances in the medical world, obesity continues to remain a major worldwide health hazard with adult mortality as high as 2.8 million per year. The majority of chronic diseases like diabetes, hypertension, and heart disease are largely related to obesity which is usually a product of unhealthy lifestyle and poor dietary habits. Appropriately tailored diet regimens for weight reduction can help manage the obesity epidemic to some extent. One diet regimen that has proven to be very effective for rapid weight loss is a very-low-carbohydrate and high-fat ketogenic diet.[1][2][3]
The severe reduction in body weight was mainly a result of FM reduction, as assessed by DXA scan; the −20.2 kg of weight reduction at the end of the study was in large part due to the −16.5 kg reduction in FM. When the FM compartment was assessed by MF-BIA, the result was very similar (−18.2 kg) and was further corroborated by the ADP analysis [−17.7 kg; Fig. 2(A)], without statistical differences among the results. It was remarkable that 3 methods of evaluating body composition, which operate through different principles, yielded such similar results. FM loss represents nearly 85% of the total weight loss achieved across the study.
There are plant based healthy oils that have been in the food chain for thousands of years, including high-fat foods such as all nuts and seeds, avocados, extra virgin olive oil, sesame seed oil, black cumin seed oil (popular in the Middle East), palm oil sourced from sustainable producers, and the healthiest plant based fat of them all, coconut oil.
“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.”
Food reward regions in the brain programmed much of this physical dependence on processed foods and refined starches. But the body can reverse it. Acute bouts of aerobic exercise have been shown to significantly suppress appetite and hunger while increasing satiety and fullness.6 Exercise in the form of resistance (weight) training can enhance insulin sensitivity,7 which results in reduced insulin secretion.8 Less insulin helps bodies favor fat burning over fat storage.

But what does the science say? Results are mixed. In one Spanish study of 20 obese adults, participants were put on a low-calorie keto diet and lost an average of 40 pounds over four months. Another small experiment had a similar outcome. In a six-month Experimental & Clinical Cardiology study of 83 obese adults, those on the keto diet lost an average of 33 pounds, while lowering their bad (LDL) cholesterol levels and increasing their good (HDL) cholesterol.


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.
