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)!
You don’t have to nix all carbs, just make sure you’re eating the right ones. A recent study published in Plant Foods and Human Nutrition found that after 12 weeks, men who ate only whole grains lost about an inch and a half off of their belly, while those who ate only refined grains didn’t lose any. Toss the white bread and pasta and stock up on complex carbs instead.

As women age, weight creeps up too, with the average women gaining about one pound per year in their 40s and 50s, resulting in an added 10 to 15 pounds. The drop in estrogen levels during this time of perimenopause (the years leading up to menopause) contributes to weight gain and can change the way you distribute fat. You may gain weight in your belly more readily than you did in younger years.


You’re more likely to eat more—and eat more high-fat, high-calorie foods—when you eat out than when you eat at home. Restaurants today serve such large portions that many have switched to larger plates and tables to accommodate them. You’ll gasp when you see just how bad the unhealthiest restaurant meals in America are. Don’t miss these 9 ways your kitchen setup can help you lose weight.
Close the Kitchen at Night. Establish a time when you will stop eating so you won't give in to the late-night munchies or mindless snacking while watching television. "Have a cup of tea, suck on a piece of hard candy or enjoy a small bowl of light ice cream or frozen yogurt if you want something sweet after dinner, but then brush your teeth so you will be less likely to eat or drink anything else," suggests Elaine Magee, MPH, RD, WebMD's "Recipe Doctor" and the author of Comfort Food Makeovers.

You don’t have to go low-carb to ditch those extra pounds around your waist in a short period of time. In fact, opting for more whole grains might just get you there faster. Researchers at Tufts University have linked eating three or more daily servings of whole grains to as much as a 10 percent reduction in visceral body fat, the kind that ups your risk for chronic diseases, like diabetes, heart disease, and high blood pressure.
We’ve now arrived at tip number 16. If you’re still having trouble losing weight, despite following the 15 pieces of advice listed above, it might be a good idea to bring out the heavy artillery: optimal ketosis. Many people stalling at weight plateaus while on a low-carb diet have found optimal ketosis helpful. It’s what can melt the fat off once again.

To prep his patients for success, Dr. Seltzer tells them to plan around a large evening meal by eating a lighter breakfast and lunch—NBD since most people who eat a meal before bed tend to wake up feeling relatively full, he says. Research suggests balanced bedtime meals may also promote steady next-day blood sugar levels, which also helps with appetite regulation.
Whereas many beverages can increase your waistline (see above), there is one that is guaranteed to trim your tummy: water. Drinking plain ol’ H2O works because staying fully hydrated tells your body it’s okay to release any extra water it’s retaining, decreasing the accompanying bloat. Plus, drinking water has been proven to reduce cravings for sweets, lower your appetite, and help you feel satiated faster. Here 9 more ways to bust belly fat in a single day!
Vegetables, preferably wild or organic and raw, should make up more than half of your plate. The majority of bulk should come from fresh green, leafy, vegetables such as kale, spinach, leaf lettuce, bok choy, collard greens, and other greens. Colorful vegetables are excellent, but limit starches, especially white potatoes and corn. Fresh veggies are best, but steamed, lightly cooked, frozen, and canned without preservatives or additives work, too.
Although fruit juice has some nutritional value, it's easy to drink large servings and take in a lot of excess calories. Juice is also missing the fiber of whole fruit, and fiber is what slows your digestion. It keeps you feeling full for longer and moderates the impact the sugar in the fruit has on your blood sugar. Most of the time, drink water or unsweetened tea instead of calorie-laden beverages..
Giancoli also recommends finding a diet that fits in with how you really live. She notes that if you enjoy going out to eat but try to commit to a diet that forbids you from ever going to a restaurant, you’re just going to cheat. “It’s not sustainable… You’re most likely going to have a healthier meal if you’re going to cook yourself, but you’re depriving yourself of that social interaction if you never go out.” To put it another way: Your eating practices shouldn’t isolate you or keep you from having fun.
The best diet is the one we can maintain for life and is only one piece of a healthy lifestyle. People should aim to eat high-quality, nutritious whole foods, mostly plants (fruits and veggies), and avoid flours, sugars, trans fats, and processed foods (anything in a box). Everyone should try to be physically active, aiming for about two and a half hours of vigorous activity per week. For many people, a healthy lifestyle also means better stress management, and perhaps even therapy to address emotional issues that can lead to unhealthy eating patterns.
Too many tough days at the office or ongoing arguments with family members can sabotage your weight-loss efforts, says Jeremy Shore, C.S.C.S., a group education director for Matrix Fitness. When your body is stressed, your cortisol levels rise, telling your body to store fat for protection, says Shore. While that might be helpful in the Amazon, it's not going to save you from your boss's emails. Shore recommends deep nasal breathing to relax. "This directs air into the lower lobes of the lungs where there are a greater number of parasympathetic nervous system receptors—stimulating repair and recovery while calming the mind," he says. Inhale and exhale deeply from the nose, spending five to eight seconds on each inhale and five to eight seconds on each exhale. 
More women perform cardio as a means to lose weight than men. This is not a stereotype—it’s reality. That’s not to say men aren’t equally guilty. (We spent part of an entire chapter in Engineering the Alpha busting the cardio-fat loss myth.) It's true cardio helps you burn calories… but so does eating. So that’s not the issue; you want to find the most efficient ways to burn calories and more importantly fat. And you want to build a body that makes it easier for you to enjoy the foods you love, right?
These may seem like exercises for guys, but not all squats are done with a barbell loaded with lots of weight. (Although women shouldn't fear heavier weights; they don’t make you bulky.) Variations of these exercises are timeless and extremely effective. Grab a pair of dumbbells and try Bulgarian split squats (Click here to see a how-to video.). Your legs and butt will thank you.
What can I eat on a no-carb diet? Many people reduce carbohydrate intake to help them lose weight. Carbohydrates are important macronutrients, but cutting them can help people to lose weight by making it possible to reduce calories and improve feelings of fullness. Alternatives to carbs can make it easier to stick to a low-carb diet. Learn more here. Read now

If you don’t have an established exercise routine, simply walking is the best first step toward weight loss. “Walking is a pretty good entry point for people,” says Gagliardi. This is particularly true if you have been out of the gym for a while and want to ease back into a workout routine. One small study published in The Journal of Exercise Nutrition & Biochemistry found that obese women who did a walking program for 50 to 70 minutes three days per week for 12 weeks significantly slashed their visceral fat compared to a sedentary control group.

Eating is for nutrition. This study analyzes weight loss, but not nutrition. I would be interested in which diet meant people had no vitamin or mineral deficiencies. Many people who eat low carbohydrate eat few vegetables and fruit because of their carbo content. I have a difficult time believing that is healthy. The extreme, of course, is the Ketogenic diet.
Watching that extra junk around your trunk turn your body into a full-blown Buddha belly puts you at an increased risk for heart disease, diabetes, and early death. Luckily, losing the weight doesn’t have to take forever; with these 22 belly fat-fighting tips, you can shave two inches off your waistline in as little as two weeks. Think your age will stand in the way of your weight loss? The 20 Ways to Lose Your Belly When You’re Older will help folks of any age get on track to their best body ever.
“One of the most under-appreciated magic fat-burning elixirs is water,” says Ajia Cherry, personal trainer and Founder at Functional Innovative Training. “As soon as you wake up in the morning, grab a glass. Every time you eat, drink a full glass of water before and during bites. The more water you drink, the fuller you will feel, the easier it is to cut back on unnecessary calories. That’s an essential element of weight and fat loss,” she explains. Other trainers concur. “Every chemical reaction in your body needs water,” celebrity trainer and creator of Methodology X Dan Roberts notes. “Even if you’re just mildly dehydrated, that could affect your fat metabolism and your performance in the gym.”
Sometimes, to whip your body into shape, you have to get a little nutty. While nuts are high in fat, it’s that very fat that makes them such powerful weapons in the war against a ballooning belly. In fact, research from Reina Sofia University Hospital reveals that study participants who consumed a diet rich in monounsaturated fats, like those in nuts, over a 28-day period gained less belly fat than their saturated fat-consuming counterparts while improving their insulin sensitivity.
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)
Other Exercises – Ab exercises will also help reduce belly fat and help you keep that tummy tone as you lose the weight. We are a huge fan of core and ab exercises here at Lose Weight by Eating, and consider them the best exercise to lose belly fat. Not only to they help you tone up fast, they also strengthen your back, fix your posture (which makes you look thinner!) and help you lose belly fat!
To prevent that from happening, says Jessica Crandall, RD, a spokesperson for the Academy of Nutrition and Dietetics and personal trainer, aim for between 20 and 30 grams first thing. She likes an egg scramble with veggies, cheese, and black beans or fills to-go coffee cups with a mix of Greek yogurt, chia seeds, nuts, and berries. Don’t miss these 13 things experts won’t tell you about weight loss.

If you want to lose body fat, going low carb – or even ketogenic – can help you program your body to burn fat for its main fuel. By reducing calorie consumption after becoming fat-adapted, you can focus on fueling with fibrous vegetables and protein, reduce fat intake, and your body will use stored body fat for energy. With consistency and dedication, this can result in rapid fat loss.


Although fruit juice has some nutritional value, it's easy to drink large servings and take in a lot of excess calories. Juice is also missing the fiber of whole fruit, and fiber is what slows your digestion. It keeps you feeling full for longer and moderates the impact the sugar in the fruit has on your blood sugar.

A relatively new offering, the Nutritarian diet is based on maximizing the amount of healthy vitamins, minerals, and trace nutrients in your food, balancing your hormones, and avoiding toxins. The plan—created by Joel Fuhrman, M.D., author of The End of Dieting—is nutrient-dense, plant-rich, and includes anti-cancer superfoods to help you not just lose weight but live a long, disease-free life. (P.S. Follow these guidelines to make sure you're absorbing all the nutrients from your food.)
Any weight loss that occurs because of these programs is almost always connected to a dramatic reduction in calories, not magical properties of the program itself. However, sudden and dramatic dietary changes can cause losses in muscle mass and general fatigue, as well as more serious complications such as disrupted gut bacteria, deficiencies in vital micronutrients, and even organ damage.[12]
If you feel guilty about your eating habits and ashamed of your body, you will always feel deprived. If you love and respect your body, it will not feel like a chore to research restaurant entrees before you go out to eat or to read nutrition labels in the grocery store or to cook for yourself and your family. Instead, it will be a privilege to take care of yourself by making smart, healthy food choices. Ardolino adds that body shape and size changes throughout our lives—and that’s OK. “If you’re consistently exercising, eating a wide range of fruits, vegetables, lean proteins, whole grains, and healthy fats, sleeping properly and managing your stress, you’re doing the best you can,” she says. “Try not to get too caught up in achieving your ‘ideal’ body; try instead to care for it—it’s the only one you’ve got.” 

"No matter how bad off you are when you start, you can still be successful," says Dawn Sabourin, 50. "Don't look at how far you have to go because you will become overwhelmed and quit." And playing the long game can help you feel more in control. "Accept where you are starting and take one step at a time in the right direction. They will build, as will your confidence and success."

I built this protocol for people who simply won’t take my advice to be patient and eat the Bulletproof Diet while using Bulletproof Intermittent Fasting. It uses biohacking techniques I pioneered on myself to reduce – but not eliminate – the risks of rapid fat loss. It prevents the metabolic harm and brain fog that come with very low-calorie diets (or multiple day fasts), and it does everything I can think of to maintain health in the face of additional toxins.  This is also not intended for people who are already fairly lean (10-14% body fat).  It is designed for obese and severely overweight people who want to lose fat as fast as possible.


Sure, there's your one friend who swears by the Taco Cleanse. And that other friend who ate nothing but broccoli soup for a month and dropped 20 pounds, found the love of her life, and got promoted at work. But before you start blending 80 stalks of broccoli into a cup or crunching your way through a crate of tacos, check out which diets are backed by science. Because don't you want to try one that will do the trick for you?
I’m in favor of any program that promotes whole foods over hyper-processed fare, and this is one thing the popular diet plans can agree on. Overly processed foods have been linked to weight gain, perhaps because many unhealthy packaged foods (think: potato chips, ice cream, frozen pizza, cookies and the like) lack the fiber found in many whole foods, including vegetables. Fiber helps fill us up, and research suggests that by simply adding more fiber to your menu, you can lose weight nearly as well as a more complicated approach. Consistently choosing whole foods is one way to do this.

While it’s often assumed that bread is off-limits when you’re trying to lose belly fat, the right bread may actually expedite the process. Switching to sprouted bread can help out carb-lovers eager to get their fix without going up a belt size, thanks to the inulin content of sprouted grains. The results of a study published in Nutrition & Metabolism reveal that found that pre-diabetic study subjects whose diets were supplemented with inulin shaved off more belly fat and total weight than those whose meal plans didn’t pack this healthy prebiotic fiber.


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)
For example, there are many photos of marathon runners without a trace of abs (google them). Even though they are under the magical 10% body fat. In similar way if you have good abs development, it will show much before you reach the 10% zone. You can see my six pack even when I am at a medium-high level of 16%-18% body fat. The leaner I go, the more it shows, but it’s visible and you judge for yourself.

Continuing weight loss may deteriorate into wasting, a vaguely defined condition called cachexia.[31] Cachexia differs from starvation in part because it involves a systemic inflammatory response.[31] It is associated with poorer outcomes.[26][31][32] In the advanced stages of progressive disease, metabolism can change so that they lose weight even when they are getting what is normally regarded as adequate nutrition and the body cannot compensate. This leads to a condition called anorexia cachexia syndrome (ACS) and additional nutrition or supplementation is unlikely to help.[28] Symptoms of weight loss from ACS include severe weight loss from muscle rather than body fat, loss of appetite and feeling full after eating small amounts, nausea, anemia, weakness and fatigue.[28]

What happens if you fast for a day? What happens if you don't eat for a day? While most people will feel hungry and possibly tired, there is also a range of other effects. In this article, learn about how the body starts to burn fat for energy and whether fasting for 24 hours can be a good weight loss tool. We also investigate the possible risks. Read now

Almonds with the content of healthy fats such as monounsaturated as well as polyunsaturated fats could help prevent people from overeating. It has well proven that consuming almonds will help suppress the hunger, defeats against heart diseases. Thanks to the rich content of magnesium, almonds help build the muscles, meaning that burning more stomach fat.
Ease into running. You might get discouraged if you attempt a jog without building up that type of strength—and this could put a damper on your motivation. "I started walking, and before long, I was running," says Cipriana Cuevas, who lost 60 pounds and eventually completed a half marathon. "Getting lighter made running easier, and, in turn, more fun."

It's not just what you eat that can make you pack on pounds—it's also how much. Before dropping 102 pounds, DeGennaro did not have a grip on proper serving sizes. "Sitting down to dinner with my husband and three kids, I'd scarf down mounds of pasta and endless rolls," she says. "Adjusting to smaller portions was tricky at first; I'd round out meals with extra veggies to keep from getting hungry."
If you drink regular, go to 2%. If you already drink 2%, go down another notch to 1% or skim milk. Each step downward cuts the calories by about 20 percent. Once you train your taste buds to enjoy skim milk, you’ll have cut the calories in the whole milk by about half and trimmed the fat by more than 95 percent. One disclaimer: There are times when fat-free dairy isn’t the best option.
It's normal to feel a few hunger pangs when you cut your calorie intake, but you don't want to feel ravenous. Filling your diet with low energy-density foods -- ones that have a low calorie count per gram -- allows you to fill up on larger portions while controlling your calorie intake. Many of these foods also supply water and fiber, which can make you feel full, to help with weight loss.
