U.S. News enlisted the help of a panel of food and health experts to rank 40 diets on a variety of measures, like how easy it is to follow, the diet’s ability to help a person lose weight in the short and long term, safety and more. The company then converted the expert’s rankings into scores that allowed them to determine the top diets. Beyond best overall diet, the experts also ranked the best diets for weight loss, healthy eating and more.
Eating too little can be extremely dangerous for your body. According to Medical News Today, having a Body Mass Index (BMI) of under 18.5 can lead to malnutrition, osteoporosis, developmental problems, a weakened immune system, anemia, and chronic fatigue. Healthline reports that the average woman needs about 2000 calories per day to maintain her weight and about 1500 calories to lose one pound of weight per week, though you should consult with your healthcare provider to see what's best for you.
If you follow food trends, you might think you have to fall in love with cauliflower and kale to reap all the rewards that veggies offer, but that isn’t the case. Be it broccoli, sweet potatoes, carrots, red peppers, cabbage, spinach, or any other vegetable, the idea is to eat a variety of them and find plenty of ways to enjoy their goodness. So if you just can’t stomach steamed Brussels sprouts, try them roasted, or give sautéed Brussels sprouts a try. If raw zucchini isn’t your thing, see if you like it spiralized into noodles or grilled on a grill pan.

For example, when it comes to hormones, ghrelin makes you hungry, leptin and other hormones keep you feeling full, Nadolsky says. Thyroid, cortisol, insulin, testosterone, and estrogen all influence how you metabolize and store energy. Meanwhile, genetics have a large influence on both basal metabolic rate (how many calories you burn just to live) and hormone health. While all of these things are impacted by our diet, they’re not only controlled by the way we eat. And, in fact, while sleep, stress management, and, when needed, medication can help regulate other hormone levels such as estrogen and thyroid, our hormones and other physiological processes are often out of our control. And by the way, being able to impact our hormone levels and metabolism with our diet doesn’t always work out in favor of weight loss. As a 2016 review notes, one of the reasons weight loss by way of caloric restriction isn’t efficacious is because “this strategy is countered by the body’s natural physiological response to negative energy balance.” In other words: The body fights back against caloric restriction.
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.

As you exercise, calories are burned and your body fat percentage decreases. So, exercising not only helps you lose belly fat, it also sheds fat from other areas. Running and walking are two of the best fat-burning exercises. Plus, the only equipment you need is a good pair of shoes. Between the two, running burns more calories, but walking really isn’t too far behind.

If you want to work late at night, think again. When your biorhythms are off, you end up eating more. When you're tired you produce more ghrelin, which triggers cravings for sugar and other fat-building foods. Losing sleep can also alter your hormone production, affecting your cortisol levels that cause insulin sensitivity, prime reasons for belly fat! Getting about 7 hours of sleep a night is one of the best things you can do for your body shaping goals.

The most important thing when it comes to weight-loss plans is to view them as a tool rather than a set of restrictions. If you don’t like one of the exercises or want to substitute one ingredient for another, go for it. As soon as a weight-loss plan becomes a weight around your neck, your motivation and dedication will take some serious knocks, so making sure the plan suits you is your best chance of success.

Sorry keto -- the Mediterranean diet is king. Endurance athletes and celebrities like LeBron James and the Kardashians have raved about the high-fat, low-carb ketogenic diet -- which was among Google’s most-searched terms this year. But Dr. Louis Aronne, an endocrinologist at NewYork-Presbyterian and Weill Cornell Medicine who runs the Comprehensive Weight Control Center, noted that the Mediterranean diet “is the only diet that has been proven in trials to promote weight loss and reduce the risk of heart attack, stroke and other cardiovascular diseases.” This meal plan includes using olive oil rich in healthy omega-3 fatty acids as your main cooking oil, and loading your plate with fruits and vegetables, whole grains and lean protein like fish and chicken, with the occasional piece of red meat. The American Heart Association recommends a similar diet that emphasizes whole, unprocessed foods, particularly fruits, veggies and whole grains, as well as low-fat dairy products, nuts and legumes, and non-tropical vegetable oils, while reducing salt, sugar and trans fats.
We pulled the top 14 of the best commercial diets (marketed to the public for profit) and the top 12 of the best diets overall. We also threw five of the most popular diet apps into the mix. Since these are largely tracking devices that don’t espouse unique eating habits, they don’t appear to meet US News’ definition of diet, but are still potentially effective weight loss tools.
There’s also the impact fiber has on your gut health. By now you’ve likely heard of the microbiome—the trillions of bacteria that live in your digestive tract. It turns out that a predominance of certain strains of bacteria may encourage inflammation and weight gain, and eating fiber-rich foods can favorably shift this balance. While it’s too soon to say that changing your microbial makeup will prompt weight loss, it’s likely to send a “hey, stop gaining weight,” message.
“We try not to vilify any food, except sugar,” added Dr. Aronne. “Having it as a treat is what sugar is for; it’s not meant to be the main part of your meal.” Yet added sugars in the form of sweeteners and syrups to flavor processed foods sees the average adult eating 20 teaspoons of hidden added sugar every day, or an extra 320 calories, according to the USDA’s recent nationwide food consumption survey. And then there’s sugar-sweetened beverages like sodas, sports drinks, juices and flavored coffees and teas stirred with empty calories. “The typical glass of orange juice has three oranges in it; that’s the calories of three oranges. But it’s easy to drink a glass of orange juice and still eat a number of other things,” added Dr. Aronne. “You’re better off just eating a single orange and feeling full.”
As with many foods, there are healthy versions and ones that make promises they can’t deliver. Some bars that promise “pure protein” have the same nutritional value as a candy bar, so it’s important to research before purchasing. Rather than just counting calories, check out the actual ingredients; is it made up of real food? Skip protein bars for weight loss that include soy in favor of ones that use proteins that include leucine, valine and isoleucine. The protein, plus the fiber and fat, will be what plays a key role in keeping you full throughout the day.

Watch your drinks. It's amazing how many calories are in the sodas, juices, and other drinks that you take in every day. Simply cutting out a can of soda or one sports drink can save you 150 calories or more each day. Drink water or other sugar-free drinks to quench your thirst and stay away from sugary juices and sodas. Choosing nonfat or low-fat milk is also a good idea.

But just because belly fat comes off a bit more easily doesn’t make it less dangerous. In fact, it’s the exact opposite. “Belly fat is unfortunately the most dangerous location to store fat,” says Dr. Cheskin. Because belly fat—also known as visceral fat, or the deep abdominal fat that surrounds your organs—is more temporary, it’s more active in terms of circulating in the bloodstream. That means it’s likely to raise the amount of fat in your blood (known as blood lipid levels) and increase your blood sugar levels, which as a result raises your risk of heart disease and type 2 diabetes.
Noom: To help you figure out how to prioritize or limit food items, Noom offers color coding. Green means go for it — “green” foods include veggies and grains, and these should make up a solid 30% of your diet. “Yellow” foods include lean meats and starches, and these can account for a touch more — 45%. “Red” foods (red meats and sweets) should appear less than both green and yellow, around 25%. When you log meals, the app lets you know how well you’re aligning with these proportions.

The trick here is not only to avoid all obvious sources of carbohydrate (sweets, bread, spaghetti, rice, potatoes), but also to be careful with your protein intake. If you eat large amounts of meat, eggs and the like, the excess protein will be converted into glucose in your body. Large amounts of protein can also raise your insulin levels somewhat. This compromises optimal ketosis.
It is not that men don’t diet. They just do it differently. They tend to include more saturated fat in their diet, while women tend to completely avoid them. Nutritionists explain, as long as they keep their intake lower than 15 per cent of their total daily fat intake, saturated fat isn’t harmful. In fact, small doses of saturated fat can help them avoid testosterone depletion.

That sour cherry is pretty sweet when it comes to your health. The results of a study conducted at the University of Michigan found that rats given high-fat foods along with tart cherries ditched nine percent more body fat than those in a control group over just 12 weeks. Cherries are also a good source of antioxidant pigment resveratrol, which has been linked to reductions in belly fat, dementia risk, and lower rates of macular degeneration among the elderly.

Diet To Go combines online support with healthy, fresh, delivered meals to help you lose weight. It’s dishes are designed by chefs, cooked freshly and delivered weekly, so all you need to do is choose, reheat and eat the meals that most appeal to you. There are three main meal plans to choose from: traditional vegetarian low carbohydrate. Traditional is simply a diverse range...
Avoid sweetened drinks. Drinks that are sweetened, whether artificially or naturally, will have little nutritional value and add lots of empty calories to your diet. Do not drink fruit juice or other sweetened drinks. Even natural sugars will increase your daily calorie intake and prevent weight loss. If you chose to drink juice, do not exceed 4 oz per day (1/2 cup). Instead of drinking sweetened beverages throughout your day, drink unsweetened, calorie-free beverages. Some beverages to avoid include:
The "all meat all the time" low-carb approach or strict veganism can be great options for people who thrive on clear diet rules (and those two are actually the most popular diets out there) but these extremes are not for everyone. If you prefer more of a moderate approach, the Flexitarian diet is the clear winner. The "flexible vegetarian" mindset allows you a healthy balance of plant-based foods, responsibly sourced meats, and quality fats. The best part? It's not super restrictive, so you have plenty of nutritious food options. (Start here: How to Adopt a Flexitarian Diet)
“My dad is like a food-pushing wizard, he’s always pulling stuff out of his pockets or showing up with delicious food,” says Mary Mock. While the family tradition of surprise sweets was fun, when it came time to lose weight, she knew she had to put a stop to all that temptation. “At first, he seemed hurt when I kept saying no but when I explained it was for my health, he got on board. Sometimes I still have to remind him though!” she says.
If figuring out what to put into your body is too overwhelming, start with how much you're serving yourself. The easiest way to do this? Swap out your plates for smaller ones, like mother of two Jeanenne Darden did. With the help of this trick, she managed to lose an amazing 22 percent of her body weight, going from 187 pounds to 146 pounds. "I ate normally," she says. "I just ate less of everything." Pro tip: This trick is even easier with some cute portion-control dishware.
Have you ever decided to skip a meal to cut back on your daily calorie count? Despite saving a few calories in the moment, this strategy almost always backfires. When you skip breakfast, or any meal, you'll begin to experience excessive hunger that can lead to craving unhealthy foods—and lots of them. You may also eat faster than you normally do after skipping a meal, causing you to miss the warning signs that you're full and resulting in overeating.

Carbohydrates are considered to be the body's main source of energy and are quickly utilized by the brain and muscles. Carbs come in two forms: simple & complex. Processed and refined sugars are simple carbs, which are digested and absorbed quickly. Complex carbs pack in more nutrients and are digested more slowly, which helps stabilize blood sugar levels.


Your phone, tablet, and television may be affecting your waist size in more ways that one. Obviously if you’re sitting on electronics then you’re not moving around and burning calories. But the effects go beyond just energy. Blue light from electronic screens can disrupt your circadian rhythms; so our addiction to electronics is reducing our sleep as people favor Netflix-bingeing to bed. Both of these effects have been linked to higher levels of belly fat. These 21 other terrible habits will make your belly fat worse.

Say cheese! Adding some extra calcium to your diet could be the key to getting that flat stomach you’ve been dreaming about. Over just 12 months, researchers at the University of Tennessee, Knoxville found that obese female study subjects who upped their calcium intake shed 11 pounds of body fat without other major dietary modifications. To keep your calcium choices healthy, try mixing it up between dairy sources, calcium-rich leafy greens, fatty fish, nuts, and seeds.
When Johns Hopkins researchers compared the effects on the heart of losing weight through a low-carbohydrate diet versus a low-fat diet for six months—each containing the same amount of calories—those on a low-carb diet lost an average of 10 pounds more than those on a low-fat diet—28.9 pounds versus 18.7 pounds. An extra benefit of the low-carb diet is that it produced a higher quality of weight loss, Stewart says. With weight loss, fat is reduced, but there is also often a loss of lean tissue (muscle), which is not desirable. On both diets, there was a loss of about 2 to 3 pounds of good lean tissue along with the fat, which means that the fat loss percentage was much higher on the low-carb diet.

Forget old low-carb diet plans that focused on processed protein bars and shakes. This year, the keto diet got high marks for low carb. Keto, short for "ketogenic," is all about training the body to burn fat for fuel. How? By eating fat—and lots of it. Most keto diets recommend getting at least 70 percent of your daily calories from fat and the rest from protein. The goal is to eat as few carbohydrates as possible. Proponents say it helps them drop weight fast with little or no hunger in addition to perks like more energy and mental clarity. (Interested? Here's everything you need to know about the keto diet.)

Trying to lose weight? Having trouble? Women often find it harder than men to shed excess pounds. In part that's because women's bodies have a tendency to "hold on" to a certain amount of fat. But in some cases the problem can be traced directly to certain habits and lifestyle traps - including many that can easily be remedied. Here are 10 weight-loss traps to watch out for:
The South Beach Diet started as a book that was originally published in 2003, The South Beach Diet: The Delicious, Doctor-Designed, Foolproof Plan for Fast and Healthy Weight Loss (Est. $9). The book is still considered to be the best way to get information on the basic diet, but there are also many follow up books and cookbooks to supplement the original, as well as South Beach compliant recipes available around the Internet. The official South Beach Diet website is mostly fee-based.
I have been on a low crab high protein diet for last six months or so and I lost up to 12 kilos, with that diet plane I was able to lose my body fat only and as for as I think so it was really helpful for me not to lose body muscles also. I want to shair that diet plane so that other can also get there desired body shape and be happy when they look them self in mirror!

There is at least one area where women have the edge, weight-wise. When men deposit fat, it most often goes to their middles, while women's excess weight tends to settle below the belt and in the middle. And it turns out that the "pear-shaped" body has a health advantage over the "apple": Those who carry extra fat mostly around their middles are at higher risk of developing heart disease than those who are bottom-heavy.
Swapping out unhealthy foods for nutritious ones gives you benefits beyond just losing weight. "I cleaned up my diet, swapping deli sandwiches with high-sodium meat and mayo for Tupperware containers or big butter-lettuce salads topped with carrots, walnuts, feta, and homemade dressing," says Jennifer Lasher, who lost 75 pounds. "I found that ditching processed foods left me with more energy, a clear head, and better skin, too."
All workouts are created equal. Should you be focusing on high intensity interval training (HIIT), training for a marathon or getting on the bodyweight bandwagon to torch the most calories and fat? “The best exercise is one that you enjoy, and one that you will actually do,” said Lieutenant Commander Katrina Piercy of the U. S. Public Health Service Commissioned Corps, and the federal lead for the 2018 Physical Activity Guidelines for Americans. Dr. John Jakicic, who chairs the American College of Sports Medicine Obesity interest group, agreed. “There is no perfect exercise,” he said. “They all count, and they all contribute in different ways. You might get something with HIIT that you might not get with yoga, and you get some benefits from yoga that you might not get with HIIT. It’s about moving, and it’s about burning calories.” So find what you can stick with in your life for weeks, months and years -- not just the first week of January. But don’t become one of the 67% of gym membership holders who never go; at around $60 a month on average, that’s wasting $720 a year.

Make sure that everything you're eating is whole — as in nothing processed or packaged. Since salt is a preservative, these are the foods that are highest in sodium — something to keep in mind when planning your meals. Plan on making sure that all items you choose are fresh. That means filling up on fresh fruits and veggies, whole grains, low-fat dairy, and lean protein.
Watch your drinks. It's amazing how many calories are in the sodas, juices, and other drinks that you take in every day. Simply cutting out a can of soda or one sports drink can save you 150 calories or more each day. Drink water or other sugar-free drinks to quench your thirst and stay away from sugary juices and sodas. Choosing nonfat or low-fat milk is also a good idea.
There’s a phenomenon I’ve see happen again and again. A husband and wife realize they’ve been enjoying their after-dinner snacks a bit too much and are seeing the numbers on the scale rise. They decide to embark on a healthy diet to shed those excess pounds and, ideally, lose weight fast. Two months later, the husband’s shed serious pounds and is looking trim, while the wife struggles to get the scale to budge, even after a diet full of kale salads and grilled chicken breast.
Use a calorie-needs calculator like LIVESTRONG.COM’s MyPlate app to figure out your daily calorie needs, then subtract calories to create your energy deficit. With an app like MyPlate, you can factor in your weight-loss goal, and it will tell you the exact number of calories (as well has how much fat, protein and carbohydrates) you need to reach that goal.
Frozen meals are super-convenient. They’re cheap, easy to throw in your bag as you’re running out the door, and take just three minutes to cook. While your 300-calorie Lean Cuisine may seem like a waist-friendly option, it’s not. Most frozen meals are loaded with sodium—as much as you should eat over a full day, not just in one meal—and lots of other synthetic additives. Sodium packs on water weight, as the body needs to maintain a balance in the body, and when you’re thirsty, you could reach for a sugary beverage, which adds hundreds of more calories. Salt also makes food taste better, prompting you to shovel more of it in your mouth. Another problem with frozen meals is they frequently lack sufficient fiber to keep you full, so you’re likely to find yourself sneaking back into the kitchen shortly after you’ve eaten. If you must eat a frozen meal, consider adding a serving or two of frozen vegetables to boost the fiber and fullness quotient and dilute the sodium.

Proponents of the Paleo diet say it's a much healthier way to eat than the standard American diet, which is often heavy on added sugars and processed foods. Critics say it's too restrictive, banning dairy, wheat and legumes -- food groups that many nutritionists feel should be part of a healthy diet. However, as we noted earlier in this section, veganism and vegetarianism also ban entire food groups and do not come under the same cloud of criticism.
Both men and women are prone to an all-or-nothing approach to weight loss (for example, after a binge, figuring, “Well, I blew it. I might as well go all out!”). But Sass says she sees more women take extreme measures to get back on track, with tactics such as juice cleanses, skipping meals or extreme dieting — not the most sustainable methods. “Most but not all men tend to just try to get back on track with the original plan, or build in a little more exercise,” she says. That is, they take a more balanced approach to getting back on track, just trying to regroup and get back on the diet, or build in a little more exercise.

“This is a great way of eating that I highly recommend to many clients, and I even model in my own life,” says Elizabeth Shaw, RDN, who is in private practice in San Diego and is the co-author of Fertility Foods Cookbook. “Since the premise of the diet is designed to help people who have high blood pressure, low-sodium foods are recommended. But considering that most Americans exceed their daily sodium levels anyway, it’s not surprising that dietitians recommend this style of eating for treating many different conditions, such as heart disease and obesity.”

Everyone is different. How quickly you burn calories when you are not physically active can be very different from other people based on your specific genes, biology, and past. While scientists know that there are 3,500 calories in one pound, simply eating 500 fewer calories every day for a week (or 3,500 fewer calories in a week) does not always end in losing exactly one pound.
