Your body needs a certain amount of essential vitamins and minerals to function properly. What happens when you don’t get enough of them? What happens when you eat too little food, or when the food you eat isn’t sufficiently nutritious? Perhaps our bodies catch on and reply by increasing hunger levels. After all – if we eat more, we increase the chances of consuming enough of whatever nutrient we are lacking.

The ketogenic diet achieved national media exposure in the US in October 1994, when NBC's Dateline television programme reported the case of Charlie Abrahams, son of Hollywood producer Jim Abrahams. The two-year-old suffered from epilepsy that had remained uncontrolled by mainstream and alternative therapies. Abrahams discovered a reference to the ketogenic diet in an epilepsy guide for parents and brought Charlie to John M. Freeman at Johns Hopkins Hospital, which had continued to offer the therapy. Under the diet, Charlie's epilepsy was rapidly controlled and his developmental progress resumed. This inspired Abrahams to create the Charlie Foundation to promote the diet and fund research.[10] A multicentre prospective study began in 1994, the results were presented to the American Epilepsy Society in 1996 and were published[17] in 1998. There followed an explosion of scientific interest in the diet. In 1997, Abrahams produced a TV movie, ...First Do No Harm, starring Meryl Streep, in which a young boy's intractable epilepsy is successfully treated by the ketogenic diet.[1]
The following measurements were made every other week: anthropometric and vital sign measurements; urine testing for ketones; and assessment for hypoglycemic episodes and other symptomatic side effects. Weight was measured on a standardized digital scale while the participant was wearing light clothes and shoes were removed. Skinfold thickness was measured at 4 sites – the average of 2 measurements at each site was entered into an equation to calculate percent body fat [12]. Waist circumference was measured at the midpoint between the inferior rib and the iliac crest using an inelastic tape; 2 measurements were averaged in the analysis. Blood pressure and heart rate were measured after the participant had been seated quietly without talking for 3 minutes. Certified laboratory technicians assessed urine ketones from a fresh specimen using the following semi-quantitative scale: none, trace (up to 0.9 mmol/L [5 mg/dL]), small (0.9–6.9 mmol/L [5–40 mg/dL]), moderate (6.9–13.8 mmol/L [40–80 mg/dL]), large80 (13.8–27.5 mmol/L [80–160 mg/dL]), large160 (>27.5 mmol/L [160 mg/dL]). Hypoglycemic episodes and symptomatic side effects were assessed by direct questioning of the participant and by self-administered questionnaires.
Flexibility. A flexible plan doesn't forbid certain foods or food groups, but instead includes a variety of foods from all the major food groups. A healthy diet includes vegetables and fruits, whole grains, low-fat dairy products, lean protein sources, and nuts and seeds. A flexible plan allows an occasional, reasonable indulgence if you like. It should feature foods you can find in your local grocery store and that you enjoy eating. However, the plan should limit alcohol, sugary drinks and high-sugar sweets because the calories in them don't provide enough nutrients.

Before starting, ask yourself what is really realistic for you, Mattinson suggests. Then get your doctor’s okay. You may also work with a local registered dietitian nutritionist to limit potential nutrient deficiencies and talk about vitamin supplementation, as you won’t be eating whole grains, dairy, or fruit, and will eliminate many veggies. “A diet that eliminates entire food groups is a red flag to me. This isn’t something to take lightly or dive into headfirst with no medical supervision,” she says.


Eat More Produce. Eating lots of low-calorie, high-volume fruits and vegetables crowds out other foods that are higher in fat and calories. Move the meat off the center of your plate and pile on the vegetables. Or try starting lunch or dinner with a vegetable salad or bowl of broth-based soup, suggests Barbara Rolls, PhD, author of The Volumetrics Eating Plan. The U.S. government's 2005 Dietary Guidelines suggest that adults get 7-13 cups of produce daily. Ward says that's not really so difficult: "Stock your kitchen with plenty of fruits and vegetables and at every meal and snack, include a few servings," she says. "Your diet will be enriched with vitamins, minerals, phytonutrients, fiber, and if you fill up on super-nutritious produce, you won't be reaching for the cookie jar."
It’s low in saturated fat. You’re not going to feel hungry eating this way, because you can build in a variety of healthy fats. But by limiting large amounts of red or processed meats and relying heavily on monounsaturated fatty acids, like avocado, nuts, or olive oil, you’ll keep saturated fat levels low. These fats don't lead to high cholesterol the same way saturated fats do. Healthful sources of fat include olive oil, fish oils, and nut-based oils, Cohen explains.
Following are two examples of menus from the book, The DASH Diet Weight Loss Solution. It features 28 days of meal plans, to help you visualize a variety of ways to put together the DASH diet. They are suggestions, and you are free to make substitutions with your favorite foods that have similar nutritional properties. This is part of the way that you will learn how to make the DASH diet into your own personal plan.

If you want to lose weight, you’d better avoid special “low-carb” products that are full of carbs. This should be obvious, but creative marketers are doing all they can to fool you (and get your money). They will tell you that you can eat cookies, pasta, ice cream, bread and plenty of chocolate on a low-carb diet, as long as you buy their brand. They’re full of carbohydrates. Don’t be fooled.
The Ketogenic Diet is a low carbohydrate diet, consisting initially of less than 20 carbohydrates per day. Not per meal, yes, you heard me correctly, per day. It is not for the faint of heart and yes I am writing from experience. Of course I have tried it! Hasn’t everybody in America at some point who has wanted to lose weight? Does it work you ask? Of course it does! The problem is how long can you keep it up?

A study published in the journal Nutrition & Metabolism discouraged the Atkins diet for anyone with diabetes because the plan doesn’t limit fat, but noted the approach may be a safe way for people without the disease to lose weight effectively. According to a study published in the Journal of the American Medical Association, Dr. Atkins helped women lose weight better than other low-carb diets, such as the Zone diet, the Ornish diet, and the LEARN diet after 12 months.
"The keto diet is primarily used to help reduce the frequency of epileptic seizures in children. While it also has been tried for weight loss, only short-term results have been studied, and the results have been mixed. We don't know if it works in the long term, nor whether it's safe," warns registered dietitian Kathy McManus, director of the Department of Nutrition at Harvard-affiliated Brigham and Women's Hospital.

About 20% of children on the ketogenic diet achieve freedom from seizures, and many are able to reduce the use of anticonvulsant drugs or eliminate them altogether.[3] Commonly, at around two years on the diet, or after six months of being seizure-free, the diet may be gradually discontinued over two or three months. This is done by lowering the ketogenic ratio until urinary ketosis is no longer detected, and then lifting all calorie restrictions.[45] This timing and method of discontinuation mimics that of anticonvulsant drug therapy in children, where the child has become seizure free. When the diet is required to treat certain metabolic diseases, the duration will be longer. The total diet duration is up to the treating ketogenic diet team and parents; durations up to 12 years have been studied and found beneficial.[9]

The Mediterranean diet might help you lose weight. While some people fear that eating a diet like the Mediterranean diet that is relatively rich in fats (think olive oil, olives, avocado and some cheese) will keep them fat, more and more research is suggesting the opposite is true. Of course, it depends on which aspects you adopt and how it compares to your current diet. If, for instance, you build a "calorie deficit" into your plan – eating fewer calories than your daily recommended max or burning off extra by exercising – you should shed some pounds. How quickly and whether you keep them off is up to you.

Wouldn’t it be great if life came with a magic remote control that made the bad parts speed up and the good parts slow down? You could hit FF at the beginning of every workday, and RWD at the end of awesome date. All the vacations, holidays and parties could move at the pace of a Kenny G song, and all the endless conference calls could spin by faster than Nicki Minaj’s hairstyles.


What the diet advocate says: 'The classic keto diet was very strict and nowadays what’s become more popular even to use from a clinical scenario is called the Modified Keto diet which is more liberal in protein. And that’s generally what people are following for weight loss and energy. That would be roughly 65-70% fat, 20-30% protein with a very small carb amount 5-10%,’ says Dr Dominic D’agostino, professor of neuropharmacology at the University of South Florida.

Cons: Eating this way perpetuates the outdated idea that dietary fat is the enemy of body fat. And it isn’t necessarily better than other diets: One study in the American Journal of Clinical Nutrition compared high-protein, normal protein, high-fat, and low-fat diets, and found no significant difference in fat loss among the groups at six months or two years (though all did result in some fat loss). What’s more, while the low-fat group was supposed to keep its intake of the macro at 20%, actual intake was closer to 26-28%, suggesting that sticking to a strict low-fat diet is rather difficult and potentially unrealistic for most.


Without peer-reviewed clinical trials, many of the benefits remain anecdotal. For instance, Weiss himself has been on a low-carb high-fat (though not strictly ketogenic) diet for more than six months, and claims he does feel much better. But he’s clear about what he knows and what he doesn’t. He’s lost weight and his borderline pre-diabetes is gone.  
The keto diet isn’t new, and it’s been around for nearly a century. It was originally developed to treat people with epilepsy. In the 1920s, researchers found that raised levels of ketones in the blood led to fewer epileptic seizures in patients. The keto diet is still used today to treat children with epilepsy who don’t respond well to anti-epileptic drugs.[2]
The subjects had a mean BMI of 42.2, mean age of 56 years, and were of either African-American or Caucasian descent. In their intervention, subjects consumed a LCKD diet with the goal of eating less than 20 grams of carbohydrates per day while reducing dosages of diabetes medication. Subjects also received nutritional counseling and medication adjustment every two weeks.

Keto decreases inflammation and improves brain function — so much so that Alzheimer’s patients who switch to a keto diet actually begin to recover their brain function, which up until now was unheard of.[20][21][22][23][24] So there’s that. (Dale Bredesen and Mark Hyman have discussed these on the Bulletproof Radio podcast. Check out Dale’s episode here, and Mark’s here.)  

Normal dietary fat contains mostly long-chain triglycerides (LCT). Medium-chain triglycerides are more ketogenic than LCTs because they generate more ketones per unit of energy when metabolised. Their use allows for a diet with a lower proportion of fat and a greater proportion of protein and carbohydrate,[3] leading to more food choices and larger portion sizes.[4] The original MCT diet developed by Peter Huttenlocher in the 1970s derived 60% of its calories from MCT oil.[15] Consuming that quantity of MCT oil caused abdominal cramps, diarrhoea and vomiting in some children. A figure of 45% is regarded as a balance between achieving good ketosis and minimising gastrointestinal complaints. The classical and modified MCT ketogenic diets are equally effective and differences in tolerability are not statistically significant.[9] The MCT diet is less popular in the United States; MCT oil is more expensive than other dietary fats and is not covered by insurance companies.[3]


It’s only dangerous to not get enough carbs at each meal if one is taking too much meds or insulin for the amount of carbs they are eating! Restricting carbohydrates doesn’t lead to hypoglycemia unawareness, but having lots of lows and lots of highs will (and decreasing insulin and carbs leads to way fewer highs and fewer lows, or at least it can). On the other hand, being in ketosis does make low blood sugars less negative as an experience. I still feel my lows just fine, but they are less of an emergency because my brain still works (feeding on ketones) and by body doesn’t freak out and release tons of adrenaline that then makes me want to eat a house. Mind you, I still wake up and know immediately if I’m low, I know from experience and how it feels in my head and body but without the crazy shakes. This is not unawareness but it is less reactive.
The keto diet is intriguing because it appears to run counter to the prevailing wisdom about the importance of lowering fat intake to prevent diabetes and heart disease, says a co-author of the new study, Gerald Grandl, PhD, a postdoctoral researcher at the Institute for Diabetes and Obesity at the Helmholtz Center in Munich. ETH Zurich conducted the study with University Children's Hospital Zurich.
"The eating plan focuses on reducing sodium intake and eating more fruits and vegetables," says Amy Gorin, MS, RDN, owner of Amy Gorin Nutrition in the New York City area. "It also emphasizes eating whole foods — such as fruits, vegetables, whole grains, fish, poultry, beans, nuts, and vegetable oils — and limits foods high in saturated fat. That includes fatty meats, full-fat dairy, and tropical oils like palm kernel oil, palm oil, and coconut oil. It also limits sugar-sweetened beverages and foods."
Although some studies have indicated that a ketogenic diet is associated with dyslipidemia (cholesterol and triglyceride perturbations), many of these results were obtained from studies on rodents and did not always agree with what the data show in human studies. A recent review summarized the controversy, highlighting the discrepancies in the literature. In part, the discordance is likely due to the exact composition of the diet, specific study design, as well as the metabolic differences between rodents and humans.
There is a lack of scientific research when it comes to the long-term effects of the keto diet. When it comes to healthy eating and weight loss, creating sustainable, lifelong changes will result in the best outcomes. Most importantly, think about how this restrictive eating plan will fit into your lifestyle, and if you are willing to give up what may be some of your favorite foods. It’s important to make time for yourself to prepare meals at home and get regular exercise. Strive for progress, not perfection.
I hate reading, but this book is laid out so you can use it in whatever way you want. It has recipes in one section, or example meal plans in another. I skipped a lot of the actual reading, and used it for all the resources it contained, This helped save me time, so I could get down to business. After the first week I was down 8 lbs. I look forward to continuing my journey. Btw the index is your friend.

The improvement in glycemic control occurred while medications for diabetes were discontinued or reduced in most participants (Table ​(Table5).5). During the study, hypertension and hyperlipidemia medication doses were not increased from baseline nor were new agents added, except in 3 individuals. No serious adverse effects related to the diet occurred. One participant had a hypoglycemic episode requiring assistance from emergency services after he skipped a meal but the episode was aborted without need for transportation to the emergency room or hospitalization.

What a great post. I thought i would add about the selection of food you eat on keto and that everyone is different. Some food gives you energy and some doesnt, this varies person to person. I started and quit keto 3 times before i managed to find my balance. The first few times it made be poorly, from the shock of diet change. However, you can wean yourself into the diet which i did the last time when i had the most success.
WOW. I guess I must be a very special, highly motivated patient then. I, of course, would never have said that about myself. My high motivation is trying to get over the hatred of food that being Diabetic gave me. I don’t feel that way anymore, and am finally happy cooking, again. (My doctor DID tell me exactly that, BTW. Even to the extent of telling me to not include the tsp of agave that I was having in my coffee once a day because sugar is sugar.)
Hi Sara. It’s meant to be a guide, as each person’s (calorie) needs varies depending on age, gender activity level etc. However, the link to the Greek Nutrition Guidelines that I have also included at the end of the post provides serving sizes. Adding the link here too: https://www.olivetomato.com/eat-like-greek-greek-dietary-guidelines-a-better-choice/

In recent years, the ketogenic diet has been attracting a lot of attention for the management of numerous health conditions, as well as for weight loss. Some controversy still exists about its safety and efficacy, largely stemming from a lack of longitudinal and mechanistic studies, inconsistencies in diet composition in different cohorts, and disagreement in conclusions between research conducted on animal vs. human populations.


Like a marathoner stretching before the big run, eating half a grapefruit before a meal can enhance your body’s fat-burning performance. A study published in the journal Metabolism found that this “warm-up” tactic can help whittle your middle—by up to an inch—in just six weeks! The scientists attribute the powerful effects to the grapefruits’ fat-zapping phytochemicals. The fruit can interact negatively with certain medications, so as long as you get the green-light from your M.D, plan to have half of a grapefruit before your morning meal and add a few segments your starter salads to reap the benefits.
The more doctors test it, the more they find that eating Mediterranean is the absolute best way to lose weight. Based on the cooking and eating styles of Italy, France, Greece, Spain, and other Mediterranean countries, the plan features olive oil, fruits and vegetables, nuts, legumes, fish and poultry, whole grains and, yes, wine! It's high in heart-healthy fats and, unlike other diets, doesn't forbid any food group. "It's hard to stay on extreme diets," says Harvard nutrition expert Walter Willett, MD, PhD, whose book Eat, Drink, and Be Healthy popularized the approach in the United States. "This diet has lots of variety and wonderful flavors so people stick with it."
As mentioned earlier, the ketogenic diet focuses on weight loss. The human body requires more effort to turn fat into energy whereas it takes less time to turn carbohydrates into energy. This is the reason; ketogenic diet helps in a quick weight loss. Since, the ketogenic diet includes some amount of protein as well; it keeps you full for a longer time. Therefore, you tend to shed those extra pounds.
Ketoacidosis (KA) is a life-threatening condition in which your body doesn’t make enough insulin. This causes you to have dangerously high levels of ketones (substances occurring when the body uses fat stores for energy) and blood sugar. The combination of both makes your blood incredibly acidic, and this can, in turn, change the normal functioning of your internal organs such as your liver and kidneys. Patients suffering from ketoacidosis must get treatment immediately or they could slip into a coma and even die.

The Keto diet versus Plate Method study triggered some challenges and a bit of criticism. In an editorial, Andrew Reynolds, PhD, a postdoctoral research fellow at the University of Otago, New Zealand, suggests that the much better results in those on the ketogenic diet may be due not to the diet itself but to the lifestyle changes and ongoing support that keto diet group received.5

Susan answered, “White bread is so refined that the nutrients are stripped down, again it’s a simple carbohydrate where when a diabetic eats something, there blood sugar will rise and you get a boost of energy. This is the difference between a whole grain and a white-refined bread, once you consume that bread your blood sugar will rise for a little while and you’ll feel energized but the whole grain has better effect on your blood sugar, sustaining that energy over a longer period of time, avoiding the ‘crash and burn’ some feel when eating white bread. Keep in mind that in white bread all of the nutrients have been processed out of the food.” The other difference, you can literally, “Taste the difference when you eat one over the other.”
To encourage ketone production, the amount of insulin in your bloodstream must be low. The lower your insulin, the higher your ketone production. And when you have a well-controlled, sufficiently large amount of ketones in your blood, it’s basically proof that your insulin is very low – and therefore, that you’re enjoying the maximum effect of your low-carbohydrate diet. That’s what’s called optimal ketosis.

Keep up electrolytes. The major electrolytes in our bodies are sodium, potassium and magnesium. Because a low carb diet (especially a keto diet!) reduces the amount of water you store, this can flush out electrolytes and make you feel sick (called “keto flu”). This is temporary, but you can avoid or eliminate it by salting your food liberally, drinking broth (especially bone broth), and eating pickled vegetables. Some people also choose to take supplements for electrolytes, but it’s best to first consult a doctor that understands and supports keto/low carb lifestyles.

I agree!! I too..have /had Diabetes II..at age 66 and retired RN, we were taught for so long the WRONG way to eat and I taught that way, the high carb, grains, etc, way to eat. KETO saved me. Dropped my A1C and I feel great. The author of this page is wrong when saying 5-10 percent of our diet, carb eating, should be root veggies like ‘carrots”…so wrong. For goodness sakes, get KETO right by educating yourself, Tammy Shiflet~ Horribly wrong! There are so many studies and physicians, brain scientists, etc out here who understand what this diet is about. Read, and educate yourself….Please! Diabetes is a symptom of the Government’s education mistakes. Sugar, Wheat, Grains…horrible for us. Get with it, we live in 2018 and the information is out there; if you need a list, just ask.
It appears that a ketogenic diet is generally safe when implemented correctly. One must be careful to obtain all the necessary nutrients by eating a variety of foods, such as non-starchy vegetables, seeds, and nuts, and also consume adequate protein and essential fatty acids. Provided that the need for vitamins, minerals, amino acids and fatty acids is met, there is no reason to suspect that the ketogenic diet is unsafe.
“For any individual considering a ketogenic diet, there are laboratory values that a knowledgeable physician should check prior to starting and throughout the course of the diet,” she says. “The best approach is to work with a registered dietitian that is knowledgeable in ketogenic diet therapies and can educate you on ways to make healthier choices on this plan than what dieters would randomly select on their own, along with appropriate supplements that are absolutely necessary on this type of diet.”
“Regardless of how solid they are, your diet and exercise plans won’t work if you aren’t sticking to them. You’ve made a commitment to yourself, so come through with it,” Roussell says. As you plan your meals or snacks, Roussell suggests putting an X over it on your menu map. If you skip a meal or eat something that isn't in your plan, circle that meal. At the end of each week, count the number of meals you ate according to your meal plan and divide that number by the total number of meals, snacks, and post-workout smoothies you had planned, then multiply it by 100.
There’s been no poultry or red meat so far in the menu, so plan for two dinners a week incorporating these animal foods instead of fish. Eat with family or friends, whenever possible, and listen to music instead of watching TV. Enjoy a glass of red wine with your meal; a moderate intake gives you polyphenols -- natural compounds in grapes -- that may protect you from heart disease, cognitive problems and even cancer.
Over 8–10 mmol/l: It’s normally impossible to get to this level just by eating a keto diet. It means that something is wrong. The most common cause by far is type 1 diabetes, with severe lack of insulin. Symptoms include feeling very sick with nausea, vomiting, abdominal pain and confusion. The possible end result, ketoacidosis, may be fatal and requires immediate medical care. Learn more
