Why is the keto diet good for you? A keto diet is one that prioritizes fats and proteins over carbohydrates. It can help reduce body weight, acne, and the risk of cancer. Find out about the mechanisms through which it achieves these benefits and the research that supports it. This MNT Knowledge Center article also discusses the risks of the diet. Read now

During the 1920s and 1930s, when the only anticonvulsant drugs were the sedative bromides (discovered 1857) and phenobarbital (1912), the ketogenic diet was widely used and studied. This changed in 1938 when H. Houston Merritt, Jr. and Tracy Putnam discovered phenytoin (Dilantin), and the focus of research shifted to discovering new drugs. With the introduction of sodium valproate in the 1970s, drugs were available to neurologists that were effective across a broad range of epileptic syndromes and seizure types. The use of the ketogenic diet, by this time restricted to difficult cases such as Lennox–Gastaut syndrome, declined further.[10]
First, a little background: Eric Westman, MD, director of the Duke Lifestyle Medical Clinic, explained to Health in a previous interview that in order to successfully follow the keto diet, you need to eat moderate amounts of protein, reduce your carb intake, and increase fats. When you reduce your carb consumption, your body turns to stored fat as its new fuel source—a process called ketosis. To stay in ketosis, followers of the keto diet must limit their carbs to 50 grams a day, Dr. Westman says.

Case in point, Steve Richert has Type 1 Diabetes and his September 1, 2015 blog The Ketogenic Diet and Type 1 Diabetes: What I Eat. He gave it the good old college try and has fearlessly came back and showed us all his results. His cholesterol increased, which just like mine, was due genetic factors, but was exacerbated by the Ketogenic Diet. So, what’s the best part of Steve’s story? He’s coming close to being right in line with what I would recommend for him! Moderation and the mediterranean diet; he’s currently trying a modified ketogenic diet or really a modified mediterranean diet. Brilliant and exactly what we all should be doing!

A study in the journal Metabolism found that eating half a grapefruit before meals may help reduce visceral fat and lower cholesterol levels. Participants in the 6-week study who ate a Rio Red grapefruit fifteen minutes before each meal saw their waists shrink by up to an inch, and LDL levels drop by 18 points. Though researchers don’t exactly know what makes grapefruit so good at burning fat, they attribute the effects to a combination of phytochemicals and vitamin C found in the tart treat.
MEME WAS TALKING ABOUT DIETS. I GOT THE BOOK ON THE DASH DIET AND I RLY LIKE IT. IT'S A DIET, YEAH, BUT IT'S ALL FOCUSED ON FEEDING YOURSELF GOOD THINGS, FOCUSING ON HITTING TARGETS FOR GETTING THE NUTRITION YOU NEED (A CERTAIN AMOUNT OF SERVINGS OF VEGGIES, FRUIT, LOW-FAT DAIRY, WHOLE GRAINS, ETC.) INSTEAD OF ON CALORIES. BUT CALORIES ARE STILL PART OF THE EQUATION, SO IT'S ALL SO FUCKING REASONABLE. IL IT.
In 1993 Oldways created the Mediterranean Diet Pyramid – in partnership with the Harvard School of Public Health and the WHO – as a healthier alternative to the USDA’s original food pyramid. Today, the Mediterranean Diet is more popular than ever, with new research every month documenting its benefits, and chefs and home cooks alike embracing Mediterranean ingredients and flavors. Starting at the base of the pyramid, you’ll find:
Hello Marylin, Yes, the Mediterranean diet has been shown to be effective for weight loss. However, you dip need to consume the right amounts of food (calories) to lose weight as that varies depending on age, gender activity level etc. Here is a link to the Greek Nutrition Guidelines that includes servings https://www.olivetomato.com/eat-like-greek-greek-dietary-guidelines-a-better-choice/
It seems strange that a diet that calls for more fat can raise “good” cholesterol and lower “bad” cholesterol, but ketogenic diets are linked to just that. It may be because the lower levels of insulin that result from these diets can stop your body from making more cholesterol. That means you’re less likely to have high blood pressure, hardened arteries, heart failure, and other heart conditions. 
The 2019 rankings include 41 of today’s most popular diets. New to the list this year is the Nordic Diet, a plant-heavy eating plan that incorporates Scandinavian traditions and ranked 9th best overall. Here’s how the rest of the rankings shook out this year, and what experts have to say about the good, the bad, and the trendy. (Here’s a hint: They’re still not crazy about keto.)
The ketogenic diet is a mainstream dietary therapy that was developed to reproduce the success and remove the limitations of the non-mainstream use of fasting to treat epilepsy.[Note 2] Although popular in the 1920s and 30s, it was largely abandoned in favour of new anticonvulsant drugs.[1] Most individuals with epilepsy can successfully control their seizures with medication. However, 20–30% fail to achieve such control despite trying a number of different drugs.[9] For this group, and for children in particular, the diet has once again found a role in epilepsy management.[1][10]
DASH stands for "dietary approach to stop hypertension" and was created by the National Institutes of Health (NIH) as a way to help reverse national trends of obesity and heart disease. Scientists combed through decades of research to come up with an expert-backed list of diet tips, along with a prescription for exercise. And it worked: The DASH diet has topped nearly every diet list for nearly a decade. Doctors particularly recommend it for people looking to lower high blood pressure, reverse diabetes, and lower their risk of heart disease. (Here's the basic list of DASH diet-approved foods.)
The herbs and spices associated with the Mediterranean diet shine at dinner. Meal options include fish like grilled salmon or pan-seared trout, seasoned with lemon and dill; chicken baked with a little olive oil and rosemary; grilled lamb chops with mint; mussels cooked in a tomato, garlic and wine broth; chili made with ground turkey, kidney beans and cayenne, or vegetarian-style with a mix of beans; and scallops sauteed with mushrooms and leeks. Have a 4-ounce serving of protein, and fill the rest of your plate with cooked veggies, like cauliflower, broccoli, brussels sprouts, or green beans.
Roussell explains that when we get too hungry, our bodies secrete a hormone called, ghrelin, which controls our hunger and appetite. If too much ghrelin is released, we get hangry and will grab pretty much anything. Before bed, however, Roussell says going to sleep a bit hungry can actually be beneficial. “Going to be hungry may actually help you sleep better as ghrelin makes your body more responsive to compounds in your brain that aid in sleep.”
Kefir is a yogurt-like substance, but it actually contains less sugar and more protein than conventional yogurt while remaining packed with gut-friendly probiotics that can help you lose weight by aiding digestion. In one study, kefir displayed weight loss properties similar to those of milk and other dairy-rich products. Other probiotic-rich foods include kombucha, bone broth, and fermented items such as sauerkraut and kimchi.
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.

One aspect that is not often mentioned is carb cravings. Before I started a keto diet, every day I would have serious starchy- or sweet- carb cravings that were uncontrollable and HAD TO BE satisfied. The high-fat keto diet has pretty much eliminated those carb cravings. It is wonderful to not be under the control of those cravings anymore. I think the high success rate of keto diets is that you are not hungry and have no cravings.

I LOVE your recipes and entire program! You simplify eating healthfully and your recipes look delicious. I have arthritis and must eat a restricted diet that is anti-inflamatory. I can easily see ways to adapt some of your recipes. The diet forbids grains, beans, wheat, chick peas, potatoes, pasta, or any fruits or vegetables with seeds, etc. I was skeptical about this diet at first but if I stick to the diet, I really do experience less pain. I would so wish to have your recipes adapted for the home cook with substitutions of allowed foods for the forbidden. For instance, I am going to try to make your phyllo recipe using almond flour, and in other recipes using only pasture grazed dairy such as goat and sheeps milk cheeses, yogurts, eggs etc. Thank your for your inspiration and I would be so grateful if you would turn your gifted cooking attention to helping those of us in pain to adapt your delicious and healthful diet to include anti-inflamation recipes. There is a huge and eager market for this.
The scale is not necessarily your friend. You may want to lose fat – but the scale measures muscles, bone and internal organs as well. Gaining muscle is a good thing. Thus weight or BMI are imperfect ways to measure your progress. This is especially true if you’re just coming off a long period of semi-starvation (calorie counting), as your body may want to restore lost muscles etc. Starting weight training and gaining muscle can also hide your fat loss.
As far as the the Ketogenic Diet goes, it is a very personal decision between you and hopefully your physician. I would just recommend working closely with your physician for all the recommended lab tests to make sure you remain healthy while on the diet. That’s really the goal of any “diet” anyway, right? To get healthy? This is why we normally always recommend moderation with everything…moderation in the foods you eat along with moderate amounts of exercise equals a healthy lifestyle that will prevent diabetes or help you control your diabetes if you already have it.
If you’re not drinking green tea with your workouts, you might be wasting your time at that barre class. A study published in The Journal of Nutrition found that after just two weeks, exercisers who sipped four to five cups of green tea each day and logged 25-minutes at the gym lost more belly fat than their non-tea-drinking counterparts. What makes the drink so powerful? It contains catechins, an antioxidant that hinders the storage of belly fat and aids rapid weight loss. And that’s not the only weight loss elixir out there: Discover more details and drop two sizes with these 4 Teas That Melt Fat Fast.

According to the official DASH Diet Weight Loss Solution page, this eating plan actually turbocharges the original DASH diet by further reducing added sugars, refined grains, and heavily-processed foods. It also includes some specific guidelines for weight loss, such as making colorful vegetables the center of your meals and adding fresh fruits to your plate whenever you get a craving for sweets.
After 32 weeks, those in the keto diet group lowered their HbA1c more than those in the plate group with more than 50% achieving a reduction to less than 6.5%, basically reversing their diabetes. None in the plate group did this well. As for weight loss, those in the keto low-carb group lost on average of 28 pounds, while those in the plate group lost an average of 6.6 pounds.1

Obviously, it’s still possible to lose weight on any diet – just eat fewer calories than you burn, right? The problem with this simplistic advice is that it ignores the elephant in the room: Hunger. Most people don’t like to “just eat less”, i.e. being hungry forever. That’s dieting for masochists. Sooner or later, a normal person will give up and eat, hence the prevalence of “yo-yo dieting”.

Milk is limited. There are no long-term risks to eating Mediterranean, says Cohen. But you may be put off if you’re big on eating a lot of milk and rely on it to get all the calcium you need. You’ll get to eat cheese and yogurt, but in smaller amounts. "To get enough calcium in the diet without milk, one would need to eat enough yogurt and cheese, or seek nondairy calcium sources," says Cohen. If needed, drink skim milk. Otherwise, nondairy calcium sources include fortified almond milk, sardines, kale, and tofu made with calcium sulfate. (30)
What the expert says: ‘There is a large amount of evidence to suggest that following the MD reduces your risk of cardiovascular disease,’ says registered Dietitian and British Dietetic Association spokesperson Kirsty Barrett. ‘Significantly, a meta-analysis of randomised-control trials in 2011 found that the MD was effective for weight loss, though results were better when the diet was combined with energy restriction and physical activity. It has also been found to reduce LDL (bad cholesterol) more than low fat and low carb diets.’
And while the diet wasn't designed with weight loss as a primary goal, it's no secret that many of the nutritional factors that influence blood pressure also influence weight, she says. Think: processed foods, trans fats, and excess sugar. According to one DASH study, adults who who followed the diet lost more weight in a span of eight to 24 weeks than those adhering to other low-calorie diets.

Tammy, just because someone follows a keto diet doesn’t mean they can’t have their sweet treats. There are dozens of websites with hundreds of keto sweet treats and “fat bombs” made with stevia or other natural non-caloric sweeteners which will not raise blood sugars. One of my favorites is Keto Mocha Mousse https://www.ruled.me/keto-mocha-mousse/ which has 5 g net carbs per servings. We don’t have to be deprived on keto.
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.
What the expert says: ‘Like with atkins, you will lose weight quickly. The ketogenic diet is used in medicine, but under strict supervision and for set periods of time, so with appropriate support it can be safe in the short to medium term. The brain does use glucose as its fuel of choice, so ‘brain fog’ lethargy are common side effects. You’ll known when your body is running off ketones by your breath – it’s known as ‘keto breath’, and it’s bad. It also can affect your ability to exercise by due to a lack of quickly accessible energy.

Mastering Diabetes: Studies conducted in tens of thousands of people over 5+ years indicate that low-carbohydrate diets increase your risk for cardiovascular disease, hemorrhagic stroke, hypertension, atherosclerosis, diabetes mortality, obesity, cancer, and all-cause mortality (premature death). No matter how you slice it, low-carbohydrate diets trick patients and doctors into believing that ketosis is an excellent long-term dietary strategy, when in reality the consequences can be disastrous.
In this single-arm, 4-month diet intervention, an LCKD resulted in significant improvement of glycemia, as measured by fasting glucose and hemoglobin A1c, in patients with type 2 diabetes. More importantly, this improvement was observed while diabetes medications were reduced or discontinued in 17 of the 21 participants, and were not changed in the remaining 4 participants. Participants also experienced reductions in body weight, waist circumference, and percent body fat but these improvements were moderate and did not predict the change in hemoglobin A1c in regression analyses.
For even more impressive effects on body composition: aim for exercise forms which elicit a positive hormonal response. This means lifting really heavy things (strength training), or interval training. Such exercise increases levels of the sex hormone testosterone (primarily in men) as well as growth hormone. Not only do greater levels of these hormones increase your muscle mass, but they also decrease your visceral fat (belly fat) in the long term.
If not managed correctly, high blood sugar in diabetics can damage blood vessels and lead to a variety of illnesses. Unmanaged diabetes doubles the risk of cardiovascular diseases such as coronary artery diseases and stroke. [3, 4] Diabetes can damage small vessels in the eyes, kidneys, and nerves and lead to complications such as blindness and kidney disease. [4]
As I wrote in op-eds for the Wall Street Journal61 and Medscape,62 the Lancet Public Health study is based on very thin data. The questionnaire underlying the report left out questions regarding popular foods, such as pizza and energy bars, and did not consider alcohol consumption. Moreover, the “low-carb” diet group in this study included people eating up to 37% of calories as carbohydrates—not low-carb according to the latest science. Ultimately, this is the kind of data that can show association but not establish causation, which means it is the kind of data one can use to generate hypotheses but not prove them. This kind of data would never be considered sufficient to approve a drug, for instance. The same standards should be applied to diet. Quite a few researchers, including myself, had our critiques published in Lancet Public Health.63 The authors replied but did not respond to most of the criticisms.
Why was the DASH diet been ranked as the best diet, the healthiest diet, and the best diet for diabetes, 8 years in a row? The expert panel of physicians assembled by US New & World Reports chose DASH because it is proven to improve health, has a balance of healthy food groups, and it actually works. And now the Mediterranean diet has jumped out in front. So delicious and heart healthy. DASH has been proven to lower blood pressure and cholesterol, and is associated with lower risk of several types of cancer, heart disease, stroke, heart failure, kidney stones, reduced risk of developing diabetes, can slow the progression of kidney disease, and now is associated with reduced risk of depression.
What the doctors never tell you is that you could also just eat completely different and take none of this crap. So that’s what I did. I stopped all of them all at once. Sure I don’t recommend that, but this damn disease and my disgusting visceral fat filled stomach ruined every aspect of my life-professional, relationships, sexual, mental. I am now 41 living back at home having to start from the bottom. I don’t want what the book recommends. I want every disgusting piece of fat off this body so I can excel again. If staying in ketosis every moment for the rest of my life will get me there then that’s what I’m going to do.
At the end of this 12 week study, scientists observed similar loss in body fat and overall body weight in all three diets. However, they noted that the VLCARB ketogenic diet was “more effective in improving tracylglycerols, HDL cholesterol, fasting and post-meal glucose and insulin concentrations. More specifically, triacylglycerols decreased by 39.9% in VLCARB subjects, 4.0% in VLF subjects, and 9.6% in HUF subjects. [11]

In 2008, researchers conducted a 24-week study to determine the effects of a low-carbohydrate diet on people with type 2 diabetes and obesity. At the end of the study, participants who followed the ketogenic diet saw greater improvements in glycemic control and medication reduction compared to those who followed a low-glycemic diet. A study from 2017 found the ketogenic diet outperformed a conventional, low-fat diabetes diet over 32 weeks in regards to weight loss and A1c. A 2013 review reports again that a ketogenic diet can lead to more significant improvements in blood sugar control, A1c, weight loss, and discontinued insulin requirements than other diets.


People claiming huge benefits of these supplements – despite the lack of solid scientific support – may sometimes have a financial reason to believe in the supplements. Some of these products are sold under a multi-level marketing arrangement, where sales people are paid based on commission. For example, the company Prüvit sells drinkable ketones, called KETO//OS with a multi-level marketing structure.
