Napping may be an easy way to catch up on some missed shut-eye, but dozing off in the middle of the day does nothing to aid weight loss. In fact, research has found that people burn fewer calories when they sleep during the day and log their waking hours after the sun’s gone down. To come to this finding, researchers at the University of Colorado at Boulder studied 14 healthy adults for six days. For two days, study participants slept at night and stayed awake during the day, then they reversed their routines to mimic the schedules of night owls. When participants slept during the day, researchers found that they burned 52 to 59 fewer calories than they did while catching their Zzzs in the evening—likely because the schedule messed with their circadian rhythm, the body’s internal clock that plays a major role in metabolism function. If your circadian rhythm is out of whack, a separate study by University of Colorado Boulder researchers suggested spending a weekend in the wilderness to get it back on track.
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.
A study in the journal Metabolism found that eating half a grapefruit before meals may help reduce visceral fat and lower cholesterol levels. Participants in the 6-week study who ate a Rio Red grapefruit fifteen minutes before each meal saw their waists shrink by up to an inch, and LDL levels drop by 18 points. Though researchers don’t exactly know what makes grapefruit so good at burning fat, they attribute the effects to a combination of phytochemicals and vitamin C found in the tart treat.
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.
A study published in The Journal of Nutrition found that after just two weeks, those who sipped four to five cups of the green brew daily in addition to working out for 25 minutes lost more belly fat than those who didn’t sip. We can chalk up these favorable results to the tea’s catechins, a type of antioxidant that hinders the storage of belly fat and aids rapid weight loss.
Diet experts say that we need about one gram of protein per kilogram of body weight to aid muscle growth and weight loss. So if that’s what you’re eating each day, you’re bound to get the body of your dreams, right? Unfortunately, there’s more to it than that. According to University of Texas researchers, the timing at which you consume your protein can make or break how much lean muscle mass you pack on. If you’re like most Americans, you likely consume little to no protein for breakfast, a bit of protein at lunch and the bulk of your daily intake during dinner—which the researchers discovered isn’t ideal for muscle synthesis. Luckily, fitness-minded friends, the fix is a simple one: Just distribute your protein intake evenly throughout the day. The scientists found that those who followed this simple trick had 25 percent higher protein synthesis than those who ate the majority of the nutrient after the sun went down.

In addition to coordinating with your dishes, the hues you surround yourself with while you chow down can impact your appetite. According to several studies, blue is an appetite suppressant. Scientists suspect this is because there aren’t many naturally-occurring blue-hued foods aside from blueberries and a handful of others. This behavior might also stem from our ancestors, who when foraging for food, stayed away from sources that were blue, black, and purple because they were believed to be poisonous. So buy some blue dishes, or freshen up your eating area with a blue tablecloth or placemats.
DIET PLANS: Do not try a crash or fad diet that suggests you eat less than 1000 to 1200 calories each day. Keep your kitchen full of healthy foods on your diet plan. Eat healthy foods from all 5 food groups each day: breads, dairy, fruits, vegetables, meat and fish. Eat only small amount of fats, like 1 to 3 teaspoons each day of oils, nuts, dressings, and margarine. Bake, roast, or broil your food instead of frying.
Friends are helpful not only because they can double as workout buddies or help hold you accountable for appropriate diet and exercise, but also because they’re a surefire way to combat gut-growing feelings of loneliness. A study in the journal Hormones and Behavior found that those who feel lonely experience greater circulating levels of the appetite-stimulating hormone ghrelin after they eat, causing them to feel hungrier sooner. Over time, folks who are perennially lonely simply take in more calories than those with stronger social support networks, so be sure to fit time with pals into your busy schedule.
27. Use tech and other tools to your advantage. "I started out just by cutting little things like soda out one by one so I wouldn't burn myself out mentally and give up. I then discovered counting calories on MyFitnessPal, which was [a huge help] for me in my weight loss. A few years in, I lost my way a little bit and found Renaissance Periodization diet templates, which helped me rebuild a healthy relationship with food."
When grabbing grub at a fast-food restaurant, the “combo” or “value meals” are typically less expensive and make you feel like you’re getting a better deal, but oftentimes they’re also nutritional nightmares. A study in the Journal of Public Policy & Marketing shows that compared to ordering à la carte, you pick up a hundred or more extra calories by opting for the aforementioned cheap “value meals.” That’s because, when you order items bundled together, you’re likely to buy more food than you need or want, and end up overeating as a result. To keep your weight in check, order your food piecemeal instead.

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.
