Food preferences: Think about whether the foods on a given diet are things that you generally enjoy. If you hate eating greens, you won’t like a diet filled with salads; but if you have a sweet tooth, a diet that substitutes milkshakes for meals might be more your speed. Consider a diet's overall approach to food and ask yourself, realistically, if you can eat the foods on this plan more or less for the rest of your life? And will you enjoy the foods on a given diet plan, or if it will feel like a “diet” food that you won’t be able to stick with long-term?
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)!
They're not FDA-regulated and therefore, what they do in your body can’t really be determined. If you’re thinking, So what?! I want to lose weight quickly and it’s okay if it doesn’t work, I still want to try! Listen up: Outside the wide range of potential pitfalls, I have much larger concern about the long-term psychological effects that come from "detoxing." The more we see words like "cleanse" and "detox," the more likely we are to believe there’s something beneficial, scientific, or "proven" about it (there isn’t). It’s a elitist shame-trigger, and its wholly unrealistic from both a physiological and mental well-being standpoint.
The keto diet did jump considerably in one specific category, however: This year it tied with several other diets for No. 2 in Best Fast Weight-Loss Diets (after the HMR Diet, a commercial plan that replaces most meals with pre-packaged nutrition bars and shakes), up from No. 13 last year. “Yes, you can do this for quick weight loss,” says Dr. Katz, “but I wouldn’t recommend it.”
Packaged meal programs: Many diet plans rely on meal-replacement bars, shakes, or other snack type foods. Still others rely on frozen entrees as a major part of your diet. Ask yourself if you are okay with a bulk of your diet relying on prepackaged snacks, shakes, or frozen meals, or if you prefer the flexibility of cooking your own meals or eating out frequently.
U.S. News’s Best Diets rankings are put together by a panel of nutritionists, dietary consultants, and doctors specializing in diabetes, heart health, and weight loss. Each member of the panel scored all 41 diets in seven different areas, including how easy they are to follow, how well they protect against chronic disease, and how likely it is that followers will actually lose weight and keep it off.
Think of each almond as a natural weight-loss pill. A study of overweight and obese adults found that, combined with a calorie-restricted diet, consuming a little more than a quarter cup of the nuts can decrease weight more effectively than a snack comprised of complex carbohydrates and safflower oil—after just two weeks! (And after 24 weeks, those who ate the nuts experienced a 62% greater reduction in weight and BMI!) For optimal results, eat your daily serving before you hit the gym. A study printed in The Journal of the International Society of Sports Nutrition found that almonds, rich in the amino acid L-arginine, can actually help you burn more fat and carbs during workouts.

Work your core. When many people think of core strengthening, they think of stomach crunches. Crunches are helpful for building abdominal muscles, but contrary to popular belief, crunches won't do much to lose the layer of fat stored in your belly, and can actually cause significant damage to the spine.[34] Instead, try a workout routine that strengthens your whole core, like yoga, or try abdominal presses and planking.[35]
U.S. News’s panel of experts noted that the Mediterranean Diet earned this year’s top spot because research suggests it can help improve longevity and ward off chronic disease. The Mediterranean Diet was also ranked No. 1 in several other categories: Easiest Diet to Follow, Best Diet for Healthy Living, and Best Diet for Diabetes. It also tied with the Ornish Diet for Best Diet for Heart Health.
Ultimately, weight-loss occurs due to a combination of factors—sleep, nutrition, mindset and physical activity all play key rolls in initiating and maintaining weight-loss. Be sure to check in with a physician before jumping into a weight-training regimen and don’t be afraid of failure. Failure is the point at which growth and change occur. Aim for three total-body, circuit-training workouts a week. If you decide to split your workouts, try to do two workouts focusing on your upper body, two workouts focusing on your lower body, and one total-body workout per week. Remember, these workouts can be as little as 20 to 30 minutes—the key is keeping the intensity high.
Many diet plans rely on meal-replacement shakes, bars or other snack type foods, while others rely on frozen entrees as a major part of your diet, like Medifast and Nutrisystem. Ask yourself if you want the bulk of your diet relying on prepackaged snacks, shakes or frozen meals, or if you prefer the flexibility of cooking your own meals or eating out frequently.
The internal and external obliques, which I like to call "nature's girdle," are located at the sides of the rectus abdominis. They are the muscles you use when you bend sideways at the spine or twist at the waist. They also contract to compress the abdomen, so you should work them just as hard as you work the rectus abdominis. Adding a twist to crunches works, as well as dumbbell side bends, but be careful not to use any jerky motions, especially if you've had back problems.

The plan limits higher-in-saturated fat foods, added sugars, and sodium by making red meat about half a serving per day and cutting back on processed food sources like condiments, sauces, breads, cereals, fast food, sweetened beverages, jam, syrups, and breakfast pastries. You'll still get to eat smaller servings of real indulgences — similar to the Mediterranean diet. The basic tenants include:
If you're reading this right now, you're probably in the market for a heart-thumping, blood-pumping, balls-to-the-wall workout. And, friend, we've got you covered. We're all about helping you get sweaty in pursuit of your goals, whether that means getting stronger, hitting a new PR, or losing weight. But let's be real for a second here: The tricky thing about weight-loss workouts is that they're kinda, sorta... a myth. Don't get me wrong—if you're trying to lose weight, a solid exercise regimen should be part of your plan. It just can't be the only part.
The bonus burn: Tamir says that a HIIT circuit using kettlebells can keep the afterburn going for 36 hours after you leave the gym. To get the best results, make sure you’re doing a fluid circuit and not stopping to rest between each move. Tamir recommends switching between upper- and lower-body movements so you can keep exercising for a longer period of time. Try doing a set of kettlebell swings, kettlebell squats, and kettlebell push presses. Then, rest for 15 to 20 seconds after completing the three moves.
TOPS also recommends that you get a diet recommendation from your doctor or follow the USDA's MyPlate tool, which focuses on filling half your plate with fruits and vegetables and the other half with lean meats and whole grains. TOPS is low-cost, nutritionally sound, provides plenty of support and is very affordable. However, it's not as structured as some other commercial weight loss programs, so those who prefer a diet that offers more specific meal guidelines may find it more difficult to follow.
Instead, we've evaluated expert reviews, most notably those published annually at U.S. News and World Report. That publication consults medical professionals who, in turn, consult clinical studies as well as utilizing their own experience and expertise to make their recommendations. We then work our way down to dieter opinions posted on survey sites -- to identify the most nutritionally sound and sustainable weight loss programs. That includes diets, meal-delivery plans, diet books and free, online resources that will help you lose weight and keep it off over the long-term.
Your body needs a certain amount of essential vitamins and minerals to function properly. What happens when you don’t get enough of them? What happens when you eat too little food, or when the food you eat isn’t sufficiently nutritious? Perhaps our bodies catch on and reply by increasing hunger levels. After all – if we eat more, we increase the chances of consuming enough of whatever nutrient we are lacking.
It's no surprise that Dr. Dean Ornish's program is such a powerful tool for weight loss, considering its easy adaptability as a lasting lifestyle. The diet is mostly plant-based, keeps sodium intake in moderation, and limits coffee to a cup a day (two cups decaf) — so if you're looking to lose weight while keeping your java flow, you may want to consider another plan.
