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)!
HIIT elicits the same health benefits as steady-state cardio, but can lead to even greater improvements in body composition, glucose metabolism, blood pressure, and cholesterol levels.[1-3] And you definitely burn more calories when you do it! Additionally, the release of hormones like epinephrine increases with high-intensity exercise, which can help your body use more fat for fuel.[1]
Not much of a coffee drinker? Tea is also a natural diuretic, and types of herbal tea such as dandelion or fennel root can also lend a hand. In fact: When a recent study compared the metabolic effect of green tea (in extract) with that of a placebo, researchers found that the green-tea drinkers burned about 70 additional calories in a 24-hour period.
Creatine, a potent muscle-builder, may also help you burn fat. The muscle added during creatine use increases your resting metabolic rate, stoking your fat-burning furnace. This is critical during a fat-loss phase, when low calorie intake can compromise your muscle mass and lower your metabolic rate. Begin with a five-day loading phase: 15-20g daily, divided into 3-4 equal doses. After that, take 3-5g of creatine per day with a meal post-exercise.
Once you’ve completed your weight-loss plan comes the hardest part of all – maintaining your weight. Hopefully, during the course of your weight-loss plan, you’ve not only acquired some useful diet tools and exercise ideas, but you’ve also met with other people trying to achieve similar goals. Use those tools and support group to help you keep the pounds from piling back on.
Regardless of how it happens, the direct benefits of weight loss are numerous. Even relatively modest amounts of weight loss can result in positive health benefits. According to a review study by D.J. Goldstein at Indiana University School of Medicine, even if you only lose less than 10% of your body weight, you can see a substantial improvement in markers associated with chronic disease (6).
Tip #3: Limit your portions. Practice portion control with every meal and snack. When you learn to fill up on less (eating until you’re 80% full, for example), weight loss follows for most people. Going Wild and becoming fat-adapted comes with a natural suppression in your appetite. Recent research shows that eating less (and intermittent fasting – see below) can provide anti-aging and longevity benefits, as well.
The Biggest Loser program has come under attack with recent revelations that its amazing, as-seen-on-TV results are both pharmaceutically assisted and likely to reverse. Living proof that the medical community’s understanding of weight loss is still evolving: The diet still stands in third place on US News’ & World Report’s list for Best Fast Weight Loss.

Other factors that can influence your decision include the program’s overall cost and your budget, whether you prefer pre-packaged options or the flexibility to eat out and cook your own meals, and finally, the degree of community interaction. Multiple studies have found that weight loss and diet control are most successful when there’s a degree of accountability and peer support. Most diet plan programs have a wide range of interactive, community-building features that can also help you gage customer satisfaction with the diet plan.
While any diet that reduces your intake of fat, sugar, and carbohydrates will help you lose weight, a weight-loss plan can offer you much more and give you a much better chance of long-term success. As weight-loss plans have been developed by dietitians, fitness coaches and nutritionists, they are designed to help you lose weight safely and progressively, while altering your attitude to food and encouraging you to adopt healthier habits.
This popular diet program is fairly restrictive — and for the first 30 days, dieters must cut out grains, legumes, most dairy, added sugar, and alcohol without any slip-ups, according to the Whole30 website. (29) The aim is to “reset” your body and to adopt dietary habits resulting in weight loss. Cutting out added sugar and alcohol has merit, but all the restrictions prove challenging and could lead to nutrient deficiencies and disordered eating.

Your weight-loss goals, personality and lifestyle al impact on your potential to lose weight, so selecting a plan that fits in with all these criteria gives you the best chance of success. Avoiding fad diets and fast-track options is important as these are rarely sustainable. When choosing a weight-loss plan, it’s important to consider the following points:


Women’s challenge with weight loss also comes down to nature. Nature wants to preserve a woman’s ability to bear children. When you’re in a calorie deficit, it can interfere with your fertility, so your body fights weight loss to prevent jeopardizing your reproductive capacity. So don’t cut more than 1,000 calories a day or eat fewer than 1,200 calories daily.
Social conditions such as poverty, social isolation and inability to get or prepare preferred foods can cause unintentional weight loss, and this may be particularly common in older people.[43] Nutrient intake can also be affected by culture, family and belief systems.[28] Ill-fitting dentures and other dental or oral health problems can also affect adequacy of nutrition.[28]

There’s mounting evidence that our body’s natural internal clocks, or circadian rhythms, drive a lot of our biological processes, including weight maintenance. They tend to sync up with daylight. That could be why studies have shown that shift workers tend to have a higher rate of obesity and weight gain—their body clocks are out of sync. One study even found that a third of people who experienced an interrupted sleep cycle for less than two weeks became prediabetic; all of the poor sleepers saw markers for the risk of obesity and type two diabetes climb.
So she started researching. She found something called the 21-Day Meal Plan, which seemed like it would work with their lives. The plan showed them what foods they could eat and what they should skip. They started by cutting sugar, junk and processed foods and added vegetables, fruit, legumes, whole grains and lean meats, such as chicken and turkey. In the first week, Parent noticed a difference.

Foods rich in the amino acid leucine can help build the lean muscle mass that’s needed to trim excess fat from your frame. Leucine is one of the most important amino acids to consume to develop lean muscle mass, says McDaniel. It literally jumpstarts the process. Great sources of the nutrient include beef, chicken, pork, tuna, milk, peanuts, lentils and eggs.

Stress causes our bodies to pump out a hormone called cortisol which causes us to build and retain belly fat.  If you’ve tried every health food, trick, cheat, and exercise under the sun but you just can’t seem to lose the weight around your waist, relax.  It may be the stress itself that is to blame.  Instead of worrying about your weight, set aside some time each day to do something you love.  Think about what makes you happy and find a way to include that in your daily routine.
Over the last three months I’ve lost 22 pounds simply by upping my exercise and reducing bad calories. I’m 68 years old, always in good shape, but added sedentary pounds as I aged. (6 feet tall, 212 pounds before — 190 pounds now) I’ve generally restricted my diet to about 1200 calories a day — 200 – 300 for breakfast, 200 for lunch, and about 700 or less for the rest of the day. I try to vary the foods, do as much exercise as I can (biking, swimming, walking, weights). I drink as much non-caloric liquid as I can and I try to find food that fills me up — vegetables, fruits, mostly. I eat some cheese and a good hamburger occasionally, although I avoid most meat. I still work full time. I realize the discipline necessary, but it’s not that hard to do. I rely on a good scale and moderate my diet each day to keep a constant weight. My blood pressure has dropped from 130/80 to 117/72 and heart rate is resting 58. I’m lucky that my chronic diseases are not yet serious (osteoarthritis and borderline cholesterol, although I dont take statins because of reactions). I’m not a diet fadder, but using common sense goes a long way. Eat smart and work out. MM
Water isn’t just a calorie-free beverage, it’s also essential to the process of metabolizing fat, known as hydrolysis, says Pence. So it’s important to drink enough fluids every day—and you’ll need even more if you’re overweight. A good rule of thumb is to drink a milliliter of water for every calorie you consume. Not into the metric system? If you’re following a 2000-calorie diet, that comes to 67 ounces or just over a half gallon of water.
“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.”

Sugary treats, while obviously delicious, aren’t very good for our bodies—and that includes our tummies. Not only do the added calories add inches to our waistlines, but sugar overload leads to insulin resistance, which tells the body to store extra fat around the waist. But that’s long-term stuff. Sugar also bloats your tummy in the short-term by feeding the bad bacteria in your gut, leading to extra gas. When it comes to flattening your belly, nixing sugar is one of the best things you can do including these 42 other easy tips to lose weight fast!
