This high-fat, adequate-protein, low-carb fad diet sends the body into a state of ketosis, in which the body uses stored fat for energy. Research published in Clinical Cardiology suggests the ketogenic, or “keto,” diet can be an effective weight loss method, but to be successful, you must follow the plan consistently with no cheat days — otherwise, you’re just eating a high-fat diet that may be high in unhealthy fats for no reason. (1) (A pro tip? If you're planning on doing the diet, consider perusing this complete keto food list and reading up on the healthiest fats for keto diet followers.)
Plain and simple: We just don't feel full by liquid calories in quite the same way as we do real food. Drinking a juice or caramel coffee drink, for instance, won't make you feel full the way eating a bowl of veggie- and protein-packed stir-fry will. So monitor your intake of juice, soda, sweetened coffee and tea, and alcoholic beverages. If you consume each of those beverages during the day, you'll have taken in at least 800 extra calories by nighttime — and you'll still be hungry. (Incidentally, alcohol may suppress the metabolism of fat, making it tougher for you to burn those calories.) Some other ways to skip sugar? Check 'em out here.
And right up there on the FF list—weight loss. Sure, slow and steady may win the race, but who wants to plod along like a tortoise, especially when a warm weather getaway is right around the corner? Add these 7 super weight loss foods to your day to get your weight-loss goals on hyperspeed. All of them have been scientifically proven to fry flab in 6 weeks or less! Tighten your seatbelt—in fact, you’ll soon be tightening every belt!
Apples, bananas, strawberries—they're all good for your body and your waistline. But to take this snack from good to great, pair it with a bit of protein to make it more satisfying. An apple and cup of skim milk is one easy option that provides 10 grams of protein and 5 grams of fiber for 200 calories. Half an avocado filled with 2 ounces of cottage cheese is another 200-calorie fruit-and-dairy combo that fills you up with 9 grams of protein and 7 grams of fiber.
Sure, you can lose weight quickly. There are plenty of fad diets that work to shed pounds rapidly -- while leaving you feeling hungry and deprived. But what good is losing weight only to regain it? To keep pounds off permanently, it's best to lose weight slowly. And many experts say you can do that without going on a "diet." Instead, the key is making simple tweaks to your lifestyle.
Yeah, yeah—you've heard a million times that you must start your day with a balanced breakfast. This advice bears repeating, however. An Imperial College London study found that when people skipped breakfast, the reward centers in their brains lit up when they were shown pictures of high-calorie foods. That means if you skip breakfast, you'll be more tempted by bad-for-you snacks later in the day. What's more, a 2013 study found that women who enjoyed a large morning meal had a larger drop in ghrelin, the hunger hormone, than those who ate a small breakfast.

Sodas and juices are essentially liquid candy: They contain up to 18 teaspoons of sugar and upwards of 240 calories per 20-ounce serving, and provide zero nutritional value. Experts point to soda as one of the top contributors to the obesity epidemic. Diet drinkers aren't off the hook, either. A study in the journal Obesity found that diet soda drinkers were more likely to have a high percentage of fat in their bellies. Researchers believe diet drinkers may overestimate the calories "saved," and then overeat. 

It can be difficult to lose weight and maintain a healthy lifestyle if you don't have adequate social support. Some weight loss programs offer in-person support group meetings, others offer one-on-one counseling via telephone or text messaging and still others use online message boards or forums to connect you with others using the plan.  Corresponding with like-minded people can make your fat-loss journey easier and more productive, but what level of accountability and interaction do you want or need? 
A cup of raspberries delivers a whopping 8 grams of fiber (that's more than double what's in a cup of strawberries and about the same amount in a cup of some types of beans). What's so great about all that fiber? Recent research in the Journal of Nutrition suggests eating more fiber as a way to prevent weight gain or even encourage weight loss. Over the course of the two-year study, the researchers found that boosting fiber by 8 grams for every 1,000 calories resulted in about 4 ½ pounds of weight lost.
Eat More Produce. Eating lots of low-calorie, high-volume fruits and vegetables crowds out other foods that are higher in fat and calories. Move the meat off the center of your plate and pile on the vegetables. Or try starting lunch or dinner with a vegetable salad or bowl of broth-based soup, suggests Barbara Rolls, PhD, author of The Volumetrics Eating Plan. The U.S. government's 2005 Dietary Guidelines suggest that adults get 7-13 cups of produce daily. Ward says that's not really so difficult: "Stock your kitchen with plenty of fruits and vegetables and at every meal and snack, include a few servings," she says. "Your diet will be enriched with vitamins, minerals, phytonutrients, fiber, and if you fill up on super-nutritious produce, you won't be reaching for the cookie jar."
Bitter orange is a currently available herbal stimulant used in some weight-loss supplements and is often called an ephedra substitute. The active ingredient in bitter orange has chemical properties and actions that are similar to ephedra and may be associated with similar adverse effects. Because of limited research and the use of bitter orange in multi-ingredient supplements, the safety of the product isn't well-understood.
Weight Watchers, The Mayo Clinic Diet, and especially Noom provide a lot of behavior-based support to integrate these good habits. These include learning portions, logging food, and both giving and receiving external support. Nutrisystem doesn’t ask for any behavior changes save for subsisting almost entirely off their pre-packaged, pre-portioned meals.
The lowest ranking diets were the Keto Diet and the Dukan Diet, which tied for last place. People who follow the Keto Diet slash carbs and fill up on fats in order to help the body enter of state of “ketosis,” where the body breaks down fat. The Dukan Diet is a rule-heavy plan that goes in stages, including a phase of eating a lot of protein. The experts rated both diets as hard to follow
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 actually builds them into your meal plans to maximize those strengths for optimal health and weight loss. The diet focuses on fiber and nutrient-rich carbs rather than empty calorie carbs that don’t do you any good. And, if done properly, you can expect to drop 8-13 pounds in the first two weeks! Take a look at some of the program highlights you can look forward to from the South Beach Diet:
The plan promotes long-lasting, sustainable changes, and undoubtedly a bounty of research backs this up. In fact, one December 2013 study in the American Journal of Medicine shows that people following Weight Watchers were close to nine times more likely to lose 10 percent of their body weight, compared to people following a self-help diet plan.

Skimping on sleep sets you up for a host of health problems, such as increased risk for depression, type 2 diabetes, and stress. Here's one other benefit to spending enough time in bed: You're more likely to be a healthy weight. University of Chicago research revealed that dieters who were well-rested lost more fat than those who were sleep deprived.
At the heart of its flexible system: SmartPoints. SmartPoints derive primarily from number of calories; sugar and saturated fat drive the number up, protein brings it down. Getting a feel for the number of points that different foods typically “cost” in order to stay on your daily “budget” is a great way to cultivate healthy decision-making: A fried chicken wing is 7 points, while 3 oz. of chicken breast without the skin is 2 points. A sugar-laden Coca-Cola is 9 points, but so is a dinner-sized serving of Moroccan chicken rice and potatoes. Some foods are zero points: fruits and vegetables, skinless chicken and turkey breast, seafood, eggs, nonfat yogurt. Being encouraged to eat certain items in this way helps to restructure your mindset around food.

Most likely, though, you've just hit a plateau, which is a fancy way of saying your body has adjusted to your lower calorie intake. To bust out of it, you need to change your workout by exercising longer or more intensely. "Cutting calories could also work, but it's not advisable to consume fewer than 1,500 calories a day because it's extremely difficult to fulfill all your nutrient needs," Sass says.

What if we told you that you could make 20 percent of your belly disappear this year—poof, just gone? Penn State University researchers compared those who consumed avocado oil with those who consumed a flax-safflower oil blend. Those on the avocado oil diet—just three tablespoons daily did the trick—lost nearly 2 percent of their belly fat in just one month.

A. "You'll be better able to maintain your weight loss if you don't have to permanently eliminate or restrict a single food group," explains Densie Webb, R.D. Low-carb diets are designed for short stints because your body simply cannot function without carbohydrates for very long. Diets that have this as their weight loss technique are appealing because they promise quick results, but studies show that after 12 months, they provide no greater weight loss benefit than a typical reduced-calorie, low-fat diet. Slow, steady weight loss is much easier to maintain for life, says Elisa Zied, R.D., a spokesperson for the American Dietetic Association.
Early-morning exercise stokes your metabolism and helps you burn more calories for the rest of the day. In fact, if you can get in 45 minutes, then Appalachian State University research shows you could experience a metabolic spike that torches an additional 190 calories over the rest of the day. Try a circuit of the basics like jumping jacks, squats, and push-ups. And for mornings you really don't have any time, try this 2-minute fat-burner.
You’ve heard of a self-fulfilling prophecy? If you keep focusing on things you can’t do, like resisting junk food or getting out the door for a daily walk, chances are you won’t do them. Instead (whether you believe it or not) repeat positive thoughts to yourself. “I can lose weight.” “I will get out for my walk today.” “I know I can resist the pastry cart after dinner.” Repeat these phrases and before too long, they will become true for you.
Simply popping a few almonds in your mouth could help you shed pounds, and not just because almonds are better for you than, say, candy. A study published in the Journal of the American Heart Association found that eating 1.5 ounces of almonds a day reduced belly and leg fat. And another study of overweight adults found that people who ate ¼ cup of almonds for 6 months had a 62 percent greater reduction in weight and BMI.

You already know to get your dressing on the side because restaurants tend to drown salads with too much. But instead of pouring it on or even dipping the leaves in, do the “fork dip.” Stick the tongs of an empty fork into the dish of dressing before skewering any salad. You’ll be surprised by how much flavor you’ll get, but with way fewer calories. Next, check out these 30 tiny diet changes that can help you lose weight.


Wrap up your morning meal with dessert—yes, really. In a Tel Aviv University Medical Center study, one group had a 304-calorie breakfast with 10 grams of carbs, while the other group ate a 600-calorie breakfast with 60 grams of carbs, which included a small sweet, such as chocolate, a doughnut, a cookie, or cake. Halfway through the 8-month study, both groups had lost an average of 33 pounds per person. At the end, however, the low-carb group regained 22 pounds, while the dessert group dropped an additional 15. Researchers say the dessert-eaters reported dealing with fewer cravings, and had a better chance of sticking to their calorie requirements for the rest of the day.
When you drink liquid carbs, like the sugar in soda, your body doesn't register them the same way as, say, a piece of bread, according to a review of studies published in Current Opinion in Clinical Nutrition & Metabolic Care. That means, even though you're taking in calories, your fullness cues aren't likely to signal that you're satisfied once you finish off a can. And that can lead to consuming more overall.
Yes, you can pump iron without bulking up, and no, you will not look awkward. Lifting weights stokes your metabolism for a few days after your workout—meaning you continue burning calories long after you leave the weight room. One study found that strength training 30 to 40 minutes twice a week for 4 months, could increase an average woman's resting metabolism by 100 calories a day.
Potassium, magnesium, and calcium can help to serve as a counter-balance for sodium. Foods that are rich in potassium include leafy greens, most "orange" foods (oranges, sweet potatoes, carrots, melon) bananas, tomatoes, and cruciferous veggies — especially cauliflower. Low-fat dairy, plus nuts, and seeds can also help give you a bloat-busting boost. They've also been linked to a whole host of additional health benefits, such as lowering blood pressure, controlling blood sugar, and reducing risk of chronic disease overall.
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.
