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.
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.
"These diets are so restrictive that of course you're going to lose weight fast because you're not eating enough calories to sustain basic activities of your body, let alone any exercise. That's nothing that any person can sustain for the long term," Hogan said. "The weight's going to come back if you do lose any weight, and then it's going to be harder to lose weight in the future."
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)!
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).
The purpose of the Mayo Clinic Diet is to help you lose excess weight and to find a way of eating that you can sustain for a lifetime. It focuses on changing your daily routine by adding and breaking habits that can make a difference in your weight, such as eating more fruits and vegetables, not eating while you watch TV, and moving your body for 30 minutes a day.
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.

Protein serves a dual role in helping you trim down belly fat by increasing muscle mass and metabolism, while also helping stave off hunger. Research shows that a higher-protein diet increases thermogenesis, which means you burn more calories. Further, eating protein leads to an increased feeling of satisfaction after the meal, often causing you to eat fewer calories later in the day. These High-Protein Breakfast Tacos are the perfect way to start your morning and will keep you feeling full until lunch.
When you're trying to lose weight, diet is one piece of the puzzle; the other is exercise. The AND recommends women over 50 engage in 30 minutes of moderate-intensity exercise -- such as a brisk walk or bike ride -- most days of the week to help burn extra calories. Two sessions per week of weight-training can help build and preserve muscle, which is beneficial for weight loss maintenance. According to the National Weight Control Registry, 94 percent of the people who have lost weight and kept it off engage in some sort of regular physical activity. If your doctor gives the okay for exercising, consult a personal trainer for fitness ideas that are right for you.
That’s because it theoretically causes a mild ketosis (yep, the basis of the keto diet), which is a fat-burning state that should make you feel less hungry. The key in being successful with a low-carb diet (especially if you’re used to a more high-carb lifestyle) is to compensate for those lost carbs with protein-rich foods, says Dr. Cheskin. That way, your volume of food stays the same, but you’re doing it healthfully rather than in a way that exacerbates your weight gain.
The amount you move around and how often you do it will change during your life, but you may not notice it happening. Did you used to play sports, dance a lot, take long walks with your dog, or run around every day after your kids? If you’re not doing any of those things now, or exercising at all, your body won’t burn calories or use energy in the same way and your weight will change.
Known as the carb-hating diet, the South Beach diet is a weight-loss food plan centered around low-carbohydrate meals. It’s important to note that the South Beach Diet doesn’t forbid carbohydrates, unlike many fad diets out there, instead, this healthy weight-loss system understands the intrinsic benefits of healthy carbs and builds them into your meal plans to maximize those strengths for optimal health and weight loss.
Luckily, that doesn’t mean you need to dedicate even more time exercising. In fact, high-intensity interval training (HIIT) workouts can slash the time commitment while boosting results. HIIT workouts last about 20 minutes and combine bursts of super-intense exercise with slower recovery phases. This type of workout has been found to help people lose more fat once the workout is over, even though they burn less calories during the workout (since workouts are shorter) and also build muscle, rather than break it down the way conventional cardio does.

Instead of satisfying your sweet tooth with some refined sugar, turn to berries and enjoy a slimmer waistline in no time. Berries are loaded with antioxidants, which can help reduce inflammation throughout the body, and research from the University of Michigan reveals that rats given a berry-rich diet shaved off a significant proportion of their belly fat when compared to a control group. Berries like strawberries, raspberries, blueberries, and blackberries are also loaded with resveratrol, an antioxidant pigment that has been linked to reductions in belly fat and a reduced risk of dementia, to boot.
Instead of subjecting yourself to another endless workout, crank up the intensity and you’ll see results faster than you ever thought possible. The results of a study conducted at McMaster University in Ontario reveal that adult male study subjects who exercised intensely for a single minute had equivalent respiratory and metabolic changes to those who worked out at a slower pace for close to an hour, so if you want to burn through that belly fat, say so long to slow and steady.
Control Your Environments. Another simple strategy to help cut calories is to control your environment -- everything from stocking your kitchen with lots of healthy options to choosing the right restaurants. That means avoiding the temptation by staying away from all-you-can-eat restaurants. And when it comes to parties, "eat a healthy snack before so you won't be starving, and be selective when you fill your plate at the buffet," suggests Ward. Before going back for more food, wait at least 15 minutes and have a big glass of water.
