From celebrity-endorsed to science-backed, finding the best diet for your body and lifestyle can be an exercise in frustration—definitely not the kind of exercise you need right now! To make your search easier, we've pulled together the 10 most popular diets based on which ones have consistently ranked highest on the annual U.S. News & World Report rankings, WebMD, and other current diet lists. Just know this: It's not about finding out which diet is the most popular overall but which one fits your goals and lifestyle the best. After all, the best diet for you is the one you can stick with (and enjoy)!
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]

A short-lived increase in seizure frequency may occur during illness or if ketone levels fluctuate. The diet may be modified if seizure frequency remains high, or the child is losing weight.[18] Loss of seizure-control may come from unexpected sources. Even "sugar-free" food can contain carbohydrates such as maltodextrin, sorbitol, starch and fructose. The sorbitol content of suntan lotion and other skincare products may be high enough for some to be absorbed through the skin and thus negate ketosis.[30]


The Mediterranean diet isn’t a regimented plan, like South Beach, the Blood Type Diet or any others; it’s more a way of eating. After World War II, researchers began studying the eating patterns of 13,000 middle-aged men in the US, Japan, Italy, Greece (including Crete), the Netherlands, Finland and Yugoslavia. They noticed that those in countries whose diets had been restricted by the deprivations of the war had lower rates of heart disease compared to American men. Moreover, residents of Crete enjoyed the best cardiovascular health, leading scientists to conclude that their diet — fruits, vegetables, grains, legumes and fish — played a major role.
Now, I know what you are going to say, “I can take a break from the diet anytime.” What do you think happens when you take that “break”? As soon as you start consuming a normal amount of carbohydrates again, you immediately go out of ketosis or the fat burning state, and your body starts storing fat again immediately. In other words, you immediately start gaining weight. So whatever weight you lost on the diet, you gain back right away. How healthy do you think it is for your body to be in a starvation mode, then in a feeding frenzy, making up for lost time?
The best diet for losing weight is Weight Watchers, according to the experts who rated the diets below for U.S. News. Volumetrics came in second, and the Flexitarian Diet, Jenny Craig and the vegan diet were third on this overall weight loss ranking list, which takes into account short-term and long-term weight loss scores. Some other diets performed as well or better in our rankings for enabling fast weight loss, but long-term weight loss is more important for your health.
With this in mind, we’ve put together a list of 40 foods that have been proven to jumpstart weight loss and will help you get to your ideal physique. To jumpstart your weight loss, we’ve selected some nutritious eats, like salsa, that are lower-calorie substitutes for less healthy choices (we’re looking at you, ketchup). And others, such as watermelon, contain certain compounds that have been scientifically proven to reduce the size of your waist and help reduce body fat. Scroll down below for a list of a few dozen weight-loss wonders, and get even more health-conscious inspiration from this list of the 40 Things Healthy Cooks Always Have in Their Kitchen!
Yet it’s an incredibly well-rounded way to lose weight that ditches gimmicks and doesn’t require calorie or macronutrient counting as other diets do. And with the emphasis on healthy fat, it’s satisfying, too. That said, the 2019 U.S. News & World Report Best Diets ranked the Mediterranean diet as No. 1 for Best Diets Overall and it ranks 17 in their list of Best Weight-Loss Diets. (3) The reviewers note that it’s not a slam dunk, and all depends on how you eat. Even healthy diets like the Mediterranean aren’t free-for-all eating plans.
The low glycaemic index treatment (LGIT)[48] is an attempt to achieve the stable blood glucose levels seen in children on the classic ketogenic diet while using a much less restrictive regimen. The hypothesis is that stable blood glucose may be one of the mechanisms of action involved in the ketogenic diet,[9] which occurs because the absorption of the limited carbohydrates is slowed by the high fat content.[5] Although it is also a high-fat diet (with approximately 60% calories from fat),[5] the LGIT allows more carbohydrate than either the classic ketogenic diet or the modified Atkins diet, approximately 40–60 g per day.[3] However, the types of carbohydrates consumed are restricted to those that have a glycaemic index lower than 50. Like the modified Atkins diet, the LGIT is initiated and maintained at outpatient clinics and does not require precise weighing of food or intensive dietitian support. Both are offered at most centres that run ketogenic diet programmes, and in some centres they are often the primary dietary therapy for adolescents.[9]
DASH was first introduced at a meeting of the American Heart Association in 1996 and later published in the New England Journal of Medicine in 1997. [2] The DASH trial randomly assigned 456 people to different diets to test the effects of dietary patterns on lowering blood pressure. The authors surmised that eating a diet with many different foods with blood pressure-lowering nutrients would show a greater effect on blood pressure than eating single nutrients, such as found in supplements or in a limited diet. Three diets were tested: 1) a control diet, or a standard American diet, 2) a fruits and vegetables diet, similar to the control diet but providing more fruits and vegetables and less snacks and sweets, and 3) a combination diet rich in fruits, vegetables, nuts, and low-fat dairy foods with reduced amounts of saturated fat, total fat, and cholesterol. The last two diets were richer in nutrients associated with lower blood pressure, such as potassium, magnesium, calcium, fiber, and protein. All three diets provided about 3000 mg sodium, which is more than the recommended amount from the Dietary Guidelines for Americans but less than the average sodium intake for Americans. [3]
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.
When you eat foods high in carbohydrates and fat, your body naturally produces glucose. Carbohydrates are the easiest thing for the body to process, and therefore it will use them first – resulting in the excess fats to be stored immediately. In turn, this causes weight gain and health problems that are associated with high fat, high carbohydrate diets (NOT keto).
Many equate healthy eating, particularly lower-sodium eating such as DASH, with the idea that all meals have to be cooked from scratch. This is overwhelming for many (myself included), but there are plenty of tricks and tips to help you. First, understand that “whole foods” doesn’t exclusively mean fresh produce. Take advantage of time-saving, minimally processed foods like unseasoned frozen vegetables and no-salt-added canned veggies.
As Tammy points out, diets are diets, and many people nowadays think/feel that diets are a “time/value-based goal”. “If I just get my weight down, or if I just fix this, then I’ll be all set…” WRONG!!! There in lies the first problem. How long can it be maintained? Well that’s a good point. The real question is, how long is one committed to changing their life, and how strong is their desire to do it. ALL things that one wants to change in life, require a change in to the way their living and/or perceiving life. They require a life-style change. One could attempt a Mediterranean diet, and yet relapse back to “normal” eating after 3mos, 1yr, 3yrs, etc.. It doesn’t really matter if the change isn’t first on the mental and emotional level. Unfortunately, many first-world daily diets (namely American) incorporate many foods that are addictive which can cause cravings. And yes, the cravings are scientifically prove-able, and have been proved. We grow up thinking that it’s “normal” to have your cake (since its the carb of debate lol) and eat it too, because why?… Well because that’s how they were raised. Simply as that. Conditioned living if you will. There are many cultures on this planet that DO NOT grow up eating as many carbs and sweets as the American Diet, and do perfectly fine without all the sugars and carb cravings. And incidentally, they also lead healthier lives too… Go figure.
What the diet advocate says: ‘FODMAPS are either absorbed slowly from the small intestine or not absorbed at all,’ says Dr Gibson, a professor of gastroenterology at Monash University in Melbourne, Australia, and the brains behind the low-FODMAP diet. ‘When the FODMAPs move into the bowel, where they are fermented by bacteria, this produces gas and can also cause water to move into the bowel. This stretches the bowel wall, which stimulates the gut.’
The idea is that the fasting induces mild stress to the cells in your body, helping them become better at coping with such stress and possibly helping your body grow stronger. The verdict is still out regarding the diet’s long-term effectiveness with weight loss, according to a review of preliminary animal research published in January 2017 in Behavioral Sciences. (17)
Christian Wolfrum, one of the corresponding authors on the paper said 'Diabetes is one of the biggest health issues we face. Although ketogenic diets are known to be healthy, our findings indicate that there may be an increased risk of insulin resistance with this type of diet that may lead to Type 2 diabetes. The next step is to try to identify the mechanism for this effect and to address whether this is a physiological adaptation. Our hypothesis is that when fatty acids are metabolized, their products might have important signaling roles to play in the brain.'
Infants and patients fed via a gastrostomy tube can also be given a ketogenic diet. Parents make up a prescribed powdered formula, such as KetoCal, into a liquid feed.[18] Gastrostomy feeding avoids any issues with palatability, and bottle-fed infants readily accept the ketogenic formula.[30] Some studies have found this liquid feed to be more efficacious and associated with lower total cholesterol than a solid ketogenic diet.[3] KetoCal is a nutritionally complete food containing milk protein and is supplemented with amino acids, fat, carbohydrate, vitamins, minerals and trace elements. It is used to administer the 4:1 ratio classic ketogenic diet in children over one year. The formula is available in both 3:1 and 4:1 ratios, either unflavoured or in an artificially sweetened vanilla flavour and is suitable for tube or oral feeding.[50] Other formula products include KetoVolve[51] and Ketonia.[52] Alternatively, a liquid ketogenic diet may be produced by combining Ross Carbohydrate Free soy formula with Microlipid and Polycose.[52]
Blueberries are lousy with antioxidants, satiating fiber, potassium, and more, and according to researchers at the University of Michigan, the colorful fruits may also encourage weight loss. In a study of laboratory rats, scientists found that after 90 days the rats who received blueberry-enriched powder as 2 percent of their diet had less abdominal fat, lower triglycerides, lower cholesterol, and improved fasting glucose and insulin sensitivity, than the rats who weren’t given any blueberry-enriched powder.

A review published in December 2015 in the journal Diabetes Therapy suggested ultra-low-carb diets were effective at managing blood sugar, decreasing weight, and managing cardiovascular risk in individuals with type 2 diabetes in the short term, but the benefits were not sustainable over the long term. When compared with higher-carb diets over a period of longer than about 12 weeks, the health results were similar.
Having tempting, unhealthy foods in your home is one of the biggest reasons for failure when starting any diet. To maximize your chances of success with the keto diet, you need to remove as many triggers as you can. This crucial step will help prevent moments of weakness from ruining all your hard work.If you aren’t living alone, make sure to discuss with your family or housemates before throwing anything out. If some items are simply not yours to throw out, try to compromise and agree on a special location so you can keep them out of sight.
There is research that supports the ketogenic diet for diabetes management, while other research seems to recommend opposing dietary treatments like a plant-based diet. Research from 2017 confirms that people with diabetes who followed a plant-based diet experienced significant improvements in blood sugars and A1c, cardiovascular disease risk factors, gut bacteria that is responsible for insulin sensitivity, and inflammatory markers like c-reactive protein.

More good news: Snacks are totally allowed (and I'm not just talking about carrot sticks). There are plenty of packaged options out there designed for keto fans. FATBAR is one of them. These snack bars have 200 calories, 16 grams of fat, and four grams of net carbs. They're also plant-based and are made with almond or cashew butter, cocoa butter, coconut, pea protein, sunflower seeds, and chia seeds.


In conclusion, these three meta-analyses indicate that low-carb isn’t a “miracle diet,” but it may be one of the best, if not the best diet, for the management of type 2 diabetes and reversal of the condition in some cases. When people with type 2 diabetes follow a low-carbohydrate ketogenic diet, their health improves, weight is lost, blood sugar and HbA1c levels drop, and other health parameters improve significantly. Even studies that put healthy individuals on a ketogenic diet found similar improvements.
Cold fried chicken breast (don’t eat the skin or coating). Hint: The chicken doesn’t have to be cold. This could be a fast-food lunch but only if you can choose whole chicken parts. (Definitely do not choose chicken tenders, patties, crispy chicken, or nuggets. They have too much breading for the amount of meat.) Most fried chicken places have coleslaw as a side. When you get back to your office, you can have the carrots and Jell‑O.

The DASH diet has sometimes even been described as an Americanized version of the famous Mediterranean diet, according to the official DASH diet website. But as healthy as the DASH diet is, it's certainly not restrictive. It includes an eating plan rich in fruits, vegetables, low-fat and nonfat dairy, lean meats, fish, poultry, nuts, beans, seeds, heart-healthy fats, and limited amounts of whole grains. These delicious and nutritious foods join forces together to help your overall health improve. An added perk? You can also shed some unwanted pounds on the DASH diet — especially if you follow the DASH Diet Weight-Loss Solution plan.

“A lot of people think the foundation of a paleo diet is high-fat meat, but I suggest that it’s vegetables,” says Hultin. The concept is to eat only foods — including meat, fish, poultry, eggs, fruits, and vegetables — that would have been available to our Paleolithic ancestors. This means grains, dairy, legumes, added sugar, and salt are all no-no’s.


Your body uses the carbohydrates you eat for energy, so if we restrict how many carbohydrates we eat, the body has to get its fuel source from fat. A byproduct of this fat burning state are ketones which are produced; this is called nutritional ketosis. You can determine if you are in this fat burning state by purchasing urine ketone testing strips from your local pharmacy.

Voted the "Best Diet Overall" for the past eight years in a row by U.S. News & World Report, the DASH diet can help you meet and maintain your health goals. The original intention of the DASH Diet (Dietary Approaches to Stop Hypertension) was to help lower high blood pressure (or hypertension), which research shows it does well. But even if you don't have high blood pressure, you might benefit from trying the DASH Diet, as research also shows it promotes weight loss and combats diabetes, all while being easy to follow and nutritious.
How can you lower your A1C levels? A1C blood tests measure how well the body is maintaining blood glucose levels. They can help diagnose diabetes and monitor diabetes treatment plans. Study results show that lowering A1C levels can reduce the risk and severity of diabetes complications. In this article, we explain how people can lower their A1C levels. Read now
The popular low-carb diets (such as Atkins or Paleo) modify a true keto diet. But they come with the same risks if you overdo it on fats and proteins and lay off the carbs. So why do people follow the diets? "They're everywhere, and people hear anecdotally that they work," McManus says. Theories about short-term low-carb diet success include lower appetite because fat burns slower than carbs. "But again, we don't know about the long term," she says. "And eating a restrictive diet, no matter what the plan, is difficult to sustain. Once you resume a normal diet, the weight will likely return."

I can’t tell you how often through the years I have been asked the question, “If I lose 20 pounds, will I no longer have diabetes?” Let me answer this very clearly, there is currently no cure for diabetes. Once you have been diagnosed, you have it for life. Every day, our most brilliant researchers are busy searching for a cure though. There is good news however; you can manage your diabetes, get it under control, prevent all the complications of diabetes and live a normal, healthy life.

A 2010 study in Diabetes, Obesity and Metabolism assigned 259 overweight diabetics to one of three diets: a low-carb Mediterranean diet, a traditional Mediterranean diet or a diet based on recommendations from the American Diabetes Association. All groups were told to exercise 30 to 45 minutes at least three times per week. After a year, all groups lost weight; the traditional group lost an average of about 16 pounds while the ADA group dropped 17 pounds and the low-carb group lost 22 pounds.
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.)
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]
The nerve impulse is characterised by a great influx of sodium ions through channels in the neuron's cell membrane followed by an efflux of potassium ions through other channels. The neuron is unable to fire again for a short time (known as the refractory period), which is mediated by another potassium channel. The flow through these ion channels is governed by a "gate" which is opened by either a voltage change or a chemical messenger known as a ligand (such as a neurotransmitter). These channels are another target for anticonvulsant drugs.[7]
HCG, or Human Chorionic Gonadotropin, is a hormone produced during pregnancy by the placenta after implantation, and doctors sometimes prescribe it for fertility issues. But this hormone has also gained popularity as a weight-loss supplement — and using it as such can be dangerous. In fact, the U.S. Food and Drug Administration (FDA) warns against purchasing over-the-counter hCG, as these supplement products are illegal. (34)
Pros: Technically a subtype of low-carb diet, the keto diet is unique: By depriving your body of carbohydrates, you not only force your body to become fat-adapted, but also, if you keep protein low as well, elevate your levels of ketone bodies, which is basically a sign your body is running on fat. The keto diet puts you in a unique metabolic state called ketosis wherein your brain burns ketones instead of glucose—and, in doing so, supposedly leads to clearer thinking. Physically, eating such a high amount of fat significantly increases your body’s ability to burn body fat, according to the study analysis. Research also shows keto athletes have a higher VO2 max, and are able to lose fat without losing strength or power.
If you are pregnant or are nursing, you should not follow a Ketogenic diet. You will not receive enough of the recommended carbohydrates, vitamins and nutrients necessary for yourself and your growing baby on this diet. Your obstetrician will recommend how many carbohydrates you should consume per meal and for snacks during each phase of your pregnancy. They will likely refer you to a Certified Diabetes Educator for nutritional counseling as well. Please check out The Diabetes Council’s FAQ’ About Gestational Diabetes for all your gestational diabetes related questions.
For the ketogenic eating plan, participants were instructed to reduce non-fiber-containing carbohydrates to between 20 and 50 grams a day, with no calorie restriction. The group following the plate method were told to eat their meals on a nine-inch plate, filling half of it with non-starchy vegetables (eg, greens, peppers, broccoli, carrots), ¼ of the plate with whole grains (eg, brown rice, sweet potatoes, whole wheat bread) and adding lean protein (eg, skinless chicken, turkey, fish, and seafood) to the last quarter of the plate.1
In 1921, Rollin Turner Woodyatt reviewed the research on diet and diabetes. He reported that three water-soluble compounds, β-hydroxybutyrate, acetoacetate and acetone (known collectively as ketone bodies), were produced by the liver in otherwise healthy people when they were starved or if they consumed a very low-carbohydrate, high-fat diet.[10] Dr. Russell Morse Wilder, at the Mayo Clinic, built on this research and coined the term ketogenic diet to describe a diet that produced a high level of ketone bodies in the blood (ketonemia) through an excess of fat and lack of carbohydrate. Wilder hoped to obtain the benefits of fasting in a dietary therapy that could be maintained indefinitely. His trial on a few epilepsy patients in 1921 was the first use of the ketogenic diet as a treatment for epilepsy.[10]
Either there are very few participants in the studies, they don’t have an even number of males vs. females, or they don’t last but a few months. One study only looked at 28 people; only 21 completed the study and 20 of these participants were men. On top of this, they were only followed for 16 weeks. Okay, so we see that 20 men can limit their carbohydrates severely for 4 months and lose weight which automatically makes their A1c come down. Great! So, the real question is, how long can these 20 men stay on this diet for the rest of their lives? How long would you like to go without eating any fresh fruit? I’m craving some now, so I’m taking a break to go grab a snack now!
The keto diet has been shown to help people lose weight in the short term; however, the long-term benefits of the diet aren't as clear, according to the Mayo Clinic. The diet is named for ketosis, which is the condition the body goes into when following the plan. In ketosis, the body uses ketone bodies, or water-soluble molecules produced by the liver and the breakdown of fatty tissue for cellular energy as opposed to sugars from ingested carbohydrates. And in some people, this results in weight-loss.
I, too, am finding the keto diet to be beneficial. My weight is moving down. My recent A1c was 5.7. I am consistently below 90 each morning when I check my blood. I am learning to adapt my cooking to the needs of maintaining this way of eating. I have incorporated walking because now I FEEL like it. I don’t feel deprived. I feel empowered. No medications for diabetes!
At your favorite Greek restaurant, order lamb souvlaki. Have a bar-of-soap-size amount of lamb (or chicken if you prefer) and a baseball-size amount of couscous or rice. Go ahead and eat all of the vegetables that come with your order, and if there is a salad, top it with 1 tablespoon of dressing. Package up the remaining lamb and rice or couscous for Sunday's lunch. Serve with 1/2 glass (2 ounces) of wine.
The first meta-analysis worth noting collected the data from 10 randomized trials comprising 1376 participants in total. [14] After analyzing the research, a key relationship emerged between dietary carbs and blood sugar levels. In short, the researchers described their finding thus: “the greater the carbohydrate restriction, the greater glucose lowering…” [14]
1. Lasting weight loss. How can a diet that features nuts, oils, pasta, bread, and wine help you lose weight? Because it makes you feel full and therefore holds hunger at bay. The healthy fats and protein in the Mediterranean diet keep your glucose (blood sugar) level on an even keel, which means you'll be less apt to hunt down chips, cookies, or fast food to get through the day.
2- Eat more vegetables, fruits, grains, and legumes. The base of the Mediterranean diet pyramid should make up the base of every meal. When you can, opt for vegetarian entrees like this Cauliflower and Chickpea Stew;  Spicy Spinach and Lentil Soup; or Spanakopita (Greek Spinach Pie). Rely more on satisfying, flavor-packed salads to make up a good portion of your plate. Some ideas: Kindey Bean Salad; Mediterranean Chickpea Salad; Greek Salad; Bean and Lentil Salad.
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.
This diet plan will be especially important for people with metabolic syndrome, prediabetes, or diabetes. Post menopausal women will find that this plans helps them lose that extra midlife weight that is so troublesome. It will reduce your body's demand for insulin, and reduce the tendency to deposit fat in your midsection. Yes, that's right - this plan will reduce your waist size, which is an important indicator of health risks.
A keto diet has shown to improve triglyceride levels and cholesterol levels most associated with arterial buildup. More specifically low-carb, high-fat diets show a dramatic increase in HDL and decrease in LDL particle concentration compared to low-fat diets.3A study in the long-term effects of a ketogenic diet shows a significant reduction in cholesterol levels, body weight, and blood glucose. Read more on keto and cholesterol >

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.
