While all fruits are healthy, a handful of them reigns supreme when it comes to frying fat and de-bloating your belly. University of Kentucky researchers found that eating watermelon can lower fat accumulation, while another group of great minds discovered that honeydew can banish water retention and bloating. Spend ten minutes chopping up these slimming fruits for the week ahead. Enjoy them solo as a snack, throw them into yogurt or add them to salads.

“They may be small, but these sweet-tasting fruits contain a hefty amount of actinidin, a natural enzyme unique to kiwifruit that aids in digestion by breaking down protein in the body. Kiwifruit also contains prebiotic fiber, which primes the gut for healthy digestion,” Scritchfield says. “Research indicates that a daily serving of green kiwifruit helps increase bowel movements. So, cut in half, scoop with a spoon, and pop into your mouth like nature’s Tums (SunGold kiwis, with a yellow flesh and tropical taste, offer three times the vitamin C of oranges and as much potassium as a medium banana).”
Good news for java lovers: The caffeine in coffee could speed up your metabolism and help your body burn slightly more calories (about 26 per cup). A study in Physiology & Behavior found that the average metabolic rate of people who drank caffeinated coffee was 16% higher than those who drank only decaf. Just be mindful of how much cream and sugar you add to your cup, which could offset any health benefits the beverage provides.
Though it’s hardly realistic to keep people from moving north, there’s evidence to suggest that those living in northern latitudes may need to be a bit more careful about their gut health than the rest of us. A study in the journal Biology Letters  found that living in northern latitudes encourages the growth of Firmicutes microbes, which have been linked to weight gain while decreasing the number of microbes linked with slim body types called Bacteroidetes. Generally speaking, the research showed that the number of Firmicutes increases with latitude and the number of Bacteroidetes decreases with latitude. To help ensure a healthy gut no matter where you reside, make sure your diet includes fermented and probiotic-rich foods, both of which encourage the growth of healthy gut bacteria.

Decision fatigue is real, and it could be hindering your ability to shed some pounds. A study published in Social Science and Medicine  found those who have high levels of what’s called “skill discretion”—i.e., they exercise control by getting things done themselves—tended to have lower BMIs. In contrast, those who are constantly deciding on courses of action for others may eventually come down with decision fatigue and make ill-informed choices, such as ordering that piece of cheesecake for dessert.

As long as you don't go nuts on nuts (which can be calorie overload), they can be super beneficial in helping you lose weight. In a study published in the European Journal of Nutrition, researchers found that those who got their protein from nuts instead of animal products had less weight gain than those who never ate them. So consider this your permission to snack on peanuts, almonds, hazelnuts, pistachios, and walnuts — so long as you practice portion control. If sodium is a concern, grab roasted or raw over salted varieties.
If you have a big celebration or date coming up, you might think it makes sense to “save” your calories for when it’s time to let loose, but this technique is rarely effective and could actually be hindering your ability to lose weight. “Although this makes sense in theory—consuming fewer calories total per day—it rarely works out as cleanly as we like,” Lisa Hayim spelled out for us in The 30 Worst Diet Mistakes You’re Making. “By the time you get to the date, and have a drink or two, the feelings of extreme hunger rush in, and you’re grabbing for whatever you can get your hands on, which is usually foods high in calories and fat. You’re so hungry, you may even end up consuming more than a day’s worth of calories in one sitting! Plus, with alcohol in your system, your body is less able to efficiently metabolize the calories,” explains Hayim. “Instead, consume normal meals throughout the day, arrive at your date cool, calm, and collected, and enjoy your cocktail and eat responsibly.”
_{If you just can’t shake those belly-bloating sugar cravings, try tyrosine—a building block of protein. It has been shown to prevent that yearning for the sweet stuff by encouraging the brain to release dopamine and another neurotransmitter, norepinephrine. In other words, eating more tyrosine (which can be found in eggs, spirulina, certain cheeses such as Parmesan, Gruyère, Swiss, and Romano, milk, sesame seeds, beef, and bacon) helps fend off those harmful sugar cravings that make your belly fat.}
Salmon is a rich source of high-quality protein and provides plenty of "good" fats: omega-3 fatty acids. A diet rich in omega-3 fatty acids helped people feel more satisfied when they were watching their calories, per a study in Appetite. Eating salmon can be a delicious and versatile way to get your recommended two weekly servings of heart-healthy fish.

Similar to Greek yogurt, a study from Nutrition Research showed that eating eggs for breakfast can make you feel more full and help you eat fewer calories throughout the day, meaning they’re quite the secret weapon for weight loss. Nutritionally speaking, one large hard-boiled egg (about 50 grams) contains less than one gram of carbs and remains an excellent source of protein. Eggs are also loaded with amino acids, antioxidants, and healthy fats.

^{People exercise for an average of 34 minutes longer with a friend than they do when they hit the gym solo, according to the American College of Sports Medicine. And the longer you sweat, the more quickly you’ll reach your goals! Looking for a healthy way to refuel after your weight room session? Whip up a quick and delicious protein shake for on-the-go nutrition.}
While we’re on the subject of water, why not throw a few lemon slices into the hydrating and satiating beverage? In addition to adding a pop of color and flavor to a tall glass of H2O, lemon can also help encourage weight loss. Just one of the bright citrus fruits contains an entire day’s worth of vitamin C, a nutrient that has the power to reduce levels of a stress hormone called cortisol that triggers hunger and fat storage. Additionally, lemons also contain polyphenols, which researchers say may ward off fat accumulation and weight gain.
When you’re done cooking, portion out just enough for your meal and pack the rest away. Putting your food away asap will not only keep it fresh for future meals but it will also deter you from mindlessly nibbling and eating more than the desired portion size. Same goes for when you’re dining out: Ask for a to-go box along with your meal, that way you can pack away the leftovers and aren’t tempted to overeat. When noshing on the leftovers at your next meal, you can also experiment with adding some additional fiber or protein to give the dish a nutritional boost.
We know that’s a hard nut to crack, but crack it you must. A big no to sauces, fried foods, and high-calorie eats. Does that sound too difficult? Well, you can take some creative steps to keep those unhealthy foods out of your way. You can skip the cheese while having sandwiches. Refrain from adding mayonnaise or butter while you are cooking something at home. Lemon and pepper make a great combination for zest. And yes, coming to soups, ditch the creamy ones and embrace the broth-based ones. Creamy and cheesy foods are possibly one of the best sources of saturated fats, and hence, carry the recipe for self-destruction. They increase bad cholesterol and make you vulnerable to heart disease (18). Above all, they cause obesity.
Yes, bacon is one of the yummiest foods out there. But there is something else you must look at – it is extremely unhealthy. Bacon contains a lot of fat, and it is the bad kind of fat. 68 percent of the total calories you get from bacon actually come from fat, and about half of that is saturated fat (13). According to one Canadian study, a diet rich in saturated fat can contribute to the development of obesity (14). Bacon can have severe repercussions, and the best way to avoid them is by avoiding bacon. You can, instead, replace it with some veggies or even eggs.

Even if you don’t typically order take-out, research suggests that just the mere presence of take-out food increases your risk of being overweight. One study printed in the British Medical Journal  found that just having a lot of take-out options near your work or along your commute to work makes you twice as likely to be obese. Though you obviously have little control over what kind of establishments populate where you live and work, this is just another reason to practice healthy eating as often as you can.

Common sense states if you want to lose weight, then you shouldn’t have a large meal not long before going to bed. And now we have additional research to back up that hypothesis. A study published in the journal Obesity followed two groups of overweight women with metabolic syndrome on identical 1,400-calorie weight loss diets for three months. While both groups consumed 500 calories at lunch, one group consumed 700 calories for breakfast and a 200-calorie dinner (the “big breakfast” group), while the other group ate 200 calories at breakfast and 700 calories at dinner (the “big dinner” group). Even though the nutrient content of the meals was exactly the same for both groups, after three months the big breakfast group lost about two and a half times more weight than big dinner group.
The best diet for losing weight is Weight Watchers, according to the experts who rated the diets below for U.S. News. Volumetrics came in second, and the Flexitarian Diet, Jenny Craig and the vegan diet were third on this overall weight loss ranking list, which takes into account short-term and long-term weight loss scores. Some other diets performed as well or better in our rankings for enabling fast weight loss, but long-term weight loss is more important for your health.
