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)!


Eating less does more for weight loss than exercising more. Consider putting the money you’d spend on a gym membership toward healthy groceries, instead. “Trying to exercise your way out of your weight problem is very difficult (because) it’s very hard to exercise that much,” explained Dr. Aronne. Burning about 3,500 calories equals one pound; someone weighing 150 pounds walking for an hour would burn around 250 calories. “You really need to cut down on calorie intake to lose the weight. Exercise is better at preventing weight gain.” The recommended daily diet is around 2,000 calories, but if you want to lose weight, Dr. Avigdor Arad, the director of the Mount Sinai Physiolab, suggests that women consume between 1,200 to 1,500 calories a day on average, and men between 1,500 and 1,800 calories. But visit your doctor to see how your own metabolism, family history and any medications you’re taking could be influencing how easily you gain and lose weight, and what your nutritional needs are. “There is a lot of variation,” he said.
Fighting belly fat is 80% healthy diet. Reduce calories by filling yourself up with protein, vegetables, whole grains, and replacing bad habit snacks with good ones. For example, if you have a sugar craving, replace your calorie laden latte with a Muscle Milk lite, one of my favorites, because it has zero sugar and a ton of protein that will satiate while also torching my sugar craving! Another great trick is a sprinkle of cinnamon in your morning coffee or oatmeal- the spice has been shown to help stabilize blood sugar. It also slows the rate at which food exits the stomach, which helps you feel fuller longer.
Lifting weights is essential for gaining and preserving muscle mass. Research on individuals with fatty liver diseases and type 2 diabetes has revealed that resistance training assists in the loss of belly fat. One study carried out on obese teenagers resulted in the highest decrease in visceral fat after a combination of weight lifting and cardio.
"When you're stressed out or tired, it's very easy to forget when your hand goes into the cookie jar," says Marisa Sherry, RD, a registered dietitian in private practice in New York City. "Are you being honest with yourself about taking just one handful here and there? When you have a cup, are you really having one cup? Most drinking glasses hold about three cups. By the end of the day, it all adds up."
Whole foods include fruits, vegetables, beans, nuts, seeds, whole grains, eggs, seafood, chicken and so on. Food philosophies may differ around which of these foods to emphasize, but that’s okay, since the evidence shows that there isn’t a single best way to lose weight. The goal is to select an approach that feels sustainable to you. If you can easily live without pasta, perhaps a low-carb method centered around veggies and quality proteins, like seafood, chicken, and lean beef would be a good fit. Vegans and vegetarians can lose weight by choosing fruits, vegetables, whole grains and plant proteins. Nut lovers may do well shedding pounds with a Mediterranean-style menu. Whatever diet appeals to your appetite and way of life, focusing on whole foods is something that all plans promote.
You know you're supposed to eat more protein to lose weight, but you might not know exactly why. Well, it actually has to do with how your body handles insulin. "Your body starts to produce more insulin as you age, since your muscle and fat cells aren't responding to it properly," explains Louis Aronne, M.D., director of the obesity clinic at Cornell University.
“The alkaline diet often has a focus on eating lots of fresh produce and unprocessed foods, which could be a good thing,” says Hultin. “However, keep in mind that this is not an evidence-based therapeutic diet. When people take it too far — for instance, drinking baking soda — or become too restrictive or obsessive over food choices, it can definitely turn negative.”

At any given time, there are dozens of weight-loss hypes in the marketplace that claim to take off 10 pounds in 10 days, or whatever. Desperation can tempt us to try anything — from "clean eating" to cutting out food groups entirely. Keep in mind: Just because an avocado-walnut-"crunchy"-kale-salad dripping in coconut oil is deemed "clean" by a so-called "expert" on your Instagram feed does not make it an unlimited food. Moral of the story? Avoid fads, eat real food, watch some Netflix, and unwind (perhaps with a glass of wine in hand). Now that's my kind of detox.


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."
Before you scarf down meal number one, get moving: Working out first thing in the morning can help you lose 20 percent more fat than exercising after breakfast, according to a 2013 study in the British Journal of Nutrition. For a quick sweat session, try this fat-burning HIIT workout that includes challenging moves like squat jumps and lunges, but can still be done in the comfort of your living room. The best part? It takes just 10 minutes to complete.
The MIND diet, or Mediterranean-DASH Intervention for Neurodegenerative Delay, is a sort of hybrid between the DASH diet and the Mediterranean diet. It features foods meant to slow the progression or development of Alzheimer’s disease, the most common form of dementia and an incurable neurodegenerative condition that more than 5 million Americans are living with, according to the Alzheimer’s Association. (12) Some research backs up this notion, including a study published in September 2016 in Alzheimer’s Dementia that found a link between following the MIND Diet and a reduced risk of the disease. (13)

When you've got a lot of weight to lose, deciding where to begin can be super-overwhelming—but we've got a good place for you to start. We've talked to dozens of women who completely transformed their bodies—we're talking shedding 50-plus pounds—and pulled together a list of the eight simple changes they made that had the biggest impact on the scale. Their tried-and-true tips might be exactly what you need to get on the path to serious results. But don't just take our word for it: These women's results speak for themselves.
For years, research has supported the fact that Weight Watchers is one of the best weight-loss diets. Thanks to its flexibility, easy-to-understand food tracking system, and group support, Weight Watchers consistently ranks number one for "best weight loss diet" and "best commercial diet" in the U.S. News & World Report rankings. (Oprah's endorsement probably didn't hurt either!) They recently revamped their program and changed their name to WW to signify a focus on overall wellness—not just weight-loss—so that users who aren't focusing on weight can also use the program to eat better, work out more, or develop a more body-positive mindset.

This is hardly surprising when you consider just how successful (or not) quick-fix diet solutions have proven to be. Research indicates that not only do nearly 70% of fad diets fail due to people neglecting to couple them an appropriate exercise regime, but 65% of people who successfully complete a fad diet will end up gaining all of their weight back within a matter of months.
The fad military diet consists of low-calorie, odd food pairings such as bun-less hot dogs with banana, carrots, and broccoli. “Any diet like the military diet that severely limits the amount of calories you consume or eliminates one or more entire food groups puts any individual at risk for nutrient deficiencies,” says Kyle. “This can be more harmful than holding onto those 10 extra lb you’re trying to lose.” (32)

Weight Watchers has been around for over five decades, and they have recently revamped their diet program to include a stronger emphasis on physical activity as well. The modern-day Weight Watchers is more of a lifestyle overhaul than a strict diet plan, and that’s what makes it so successful. People looking to change their lifestyles permanently benefit from the extensive resources and the support of a large online community.
A common misconception amongst many female fitness enthusiasts is that steady-state cardio in the "fat burning zone" is ideal for weight loss. Spending two hours on the treadmill may seem like it'll get you bikini-worthy bod—more minutes, more calories, right? However, while steady-state cardio has many benefits, it isn't the most effective way to reduce body fat.[1]
Very low levels of thyroid hormone usually indicate an autoimmune reaction to the thyroid gland itself. This means you’ll have to take thyroid hormone supplements orally, usually the stable form T4 (Levaxin), which your doctor can prescribe for you. Your body will transform this into the active T3 hormone when necessary. The supplement dose should be adjusted so that you reach normal hormone levels (TSH, T3, T4) and sufficiently alleviate symptoms – though a few people feel best when keeping TSH slightly below normal.
These are very convenient if you don't have the time, energy or ability to plan for and prepare meals. A prepackaged food program gives you a no-hassle, no-brainer approach to dieting, but the best come at a cost. Even the least expensive prepackaged plans cost more than just buying your own food, and it can be difficult to find out the true cost until you actually commit. Still, if you can afford it, you get a nutritionally balanced, calorie-controlled eating plan with lots of support and no additional tools needed -- except a microwave oven, which are covered in a separate report.
A 2018 study among more than 600 adults who were tracked for a year concluded that while there are different paths to weight loss, the advice to limit added sugars and refined grains, add more veggies to your plate, and eat more whole foods — in other words, focusing on the quality of your diet — is the way to go. People who followed this advice lost weight without worrying about calories.
“When a client comes to me looking to go down a size or lose fat around their midsection, I’ll often suggest that they do more cardio,” says Cherry. “Many assume that they need to increase their number of abdominal exercises, but the reality is cardio is the most effective strategy—and it doesn’t all have to take place in the gym. Walk more, take the stairs, get up every hour at work. All this extra movement will help to strip away the layers of fat covering your abdominal muscles.”
Also, the natural sugar in fruit does affect your carbohydrate intake — especially if you eat a lot of fruit. This may temporarily raise your blood sugar or certain blood fats. However, this effect is lessened if you are losing weight. If you have diabetes or any other health conditions or concerns, work with your doctor to adjust the Mayo Clinic Diet for your situation. For example, people with diabetes should aim for more vegetables than fruits, if possible. It's a good idea to snack on vegetables, rather than snacking only on fruit.
Foods that have thermogenic properties burn your calories as you eat them. Protein is highly thermogenic. Animal proteins are more thermogenic than vegetable proteins. Thus, lean meats are the best calorie burning food. When you eat lean meat, you burn about 30 percent of the calories it contains within it just by digesting the food. So, if you eat a 300 calorie chicken breast, you will use about 90 calories to digest it. It’s wise to include some protein in each of your meal. This can be lean chicken, beef, or pork, especially in dinner so that you burn most of the consumed calories through digestion at a time when your body’s metabolism is slower. Just remember, do not fry your lean meat!

Intermittent fasting—limiting your eating hours to just eight, say between 10:30 and 6:30—has gained popularity as a way to shake up your metabolism, and it just might work. “There is a lot more research that needs to be done but it does seem to benefit some people, particularly men,” says Angel Planells, RD, a spokesperson for the Academy of Nutrition and Dietetics based in Seattle. Another approach is to fast—or eat next to no calories (500-600 calories total)—two non-consecutive days a week. (You can eat normally the other five days.) The tactic seems to increase fat burning. “When your body isn’t getting fuel, it will start burning fat,” Planells says. Read about this woman’s experience with intermittent fasting.
And at the gym, that difference just gets exacerbated. Women, worried about bulking up, tend to lift lighter weights and focus more on cardiovascular fitness, while men tend to gravitate toward the kind of heavy lifting that boosts muscle composition and metabolic rate, says Jim White, a Virginia Beach-based nutrition expert and certified personal trainer.
And as people get older they tend to become less active, which means you burn fewer calories all day long. Plus, you naturally lose muscle mass due to hormonal changes, which further drops your daily calorie-burn rate. Muscle tissue burns more calories than fat tissue, so a body with less lean tissue has a lower metabolism and is prone to weight gain.
●Personalize your portions. If you’re a woman eating with a man, customize your portions to suit your body’s needs, says Sass. That might mean more veggies and smaller servings of protein and foods with starch and fat. For example, on burrito night, skip the tortilla in favor of a bed of greens, and stick to a piece of lean protein the size of a smartphone, a small scoop of a healthful starch such as brown rice and a dollop of guacamole.
When you’re cutting calories, it can be tough to make sure you’re still getting enough of all the good stuff your body runs on. “Nutrient deficiencies can stall or halt weight loss,” says Crandall. She sees lots of patients with low levels of vitamin D, for example, a nutrient that is critical to parathyroid hormone function—it helps with weight regulation. If you’re not eating a well-balanced diet, a multivitamin can be a good way to bridge those nutritional gaps and make sure you’re not missing anything that could impede weight loss or muscle building, such as calcium or iron.

Sleep quality matters as much as quantity, according to Gillespie. In general, an uninterrupted seven hours is better than 12 hours of tossing and turning. Of course, for new moms or others for whom sleep is hard to come by, naps are better than nothing. But if it’s possible to get your nightly sleep done in a solid block, that’s your best bet, she says.
There's no way around the fact that, when it comes to burning more fat, you have to work at it. There is no magic exercise, workout, or pill that will do the job for you. The good news is that it doesn't take much activity to push the body into that fat burning mode. Try incorporating some type of activity every day, even if it's just a quick walk, and build on that over time as it becomes more of a routine. Do that and you're on the way to burning more fat.

Yes, you read that right! “Get rid of your low-fat and fat-free yogurts, milk, and cheeses. Full-fat dairy (and many of these 20 Best Full-Fat Foods for Weight Loss) contains anti-inflammatory fatty acids, like butyrate and conjugated linolenic acid (CLA), that can support healthy metabolic function and fat-burning, says Minchen. “Additionally, full-fat dairy contains vitamins A and K, two vitamins that need fats to be absorbed and metabolized.” However, fair warning: full-fat products do carry more calories, so be sure to cut back elsewhere so you don’t up your total calorie count.
