In a 2015 study in the Journal of the Association for Consumer Research , scientists instructed subjects to choose either a fruit salad or a chocolate cake, then eat and evaluate their snack. Those who ate the chocolate cake in the room with the mirror found it less appealing than those who didn’t have a looking glass nearby, but those who opted for the fruit salad reported no difference in taste. In other words, the presence of a mirror makes unhealthy foods less appealing. So hang one in your kitchen to discourage the consumption of cake and the like, and then use it to watch your waistline shrink each day!
By now, you probably know that coffee can help curb your appetite. But did you also know it can boost your metabolism? Since coffee contains the antioxidant chlorogenic acid (CGA), it can actually increase your body’s use of fat for energy. Research has additionally shown that CGA can slow the release of glucose and lower insulin resistance to inhibit weight gain after eating a meal.
Drinking enough water can help you stay slim, too. Research from the American Chemical Society in Boston found that having two 8-ounce glasses of water before a meal while also reducing portion sizes could help you lose weight and keep it off. Not to mention, water fills you up, curbing your appetite: "In addition to slightly boosting your metabolism, drinking water before meals has been shown to help you eat less without trying," says Sass.
Though you may think skipping a meal such as breakfast will help you lose weight because you would be consuming fewer calories, numerous studies have actually shown that bailing on breakfast is bad for your waistline. Why, you ask? It turns out that skipping breakfast not only means you’ll likely consume more calories later in the day, but eating more calories in the later part of the day is a nightmare for metabolic circadian rhythms, which help keep your weight in check.
Yes, peanut butter is high in calories, but if you stick the real stuff—a tasty combo of peanuts and maybe a touch of salt—the legumes can earn a place as one of the best foods for weight loss. In addition to providing you with belly-slimming monounsaturated fats, tummy-filling fiber, and metabolism-boosting protein, peanuts also contain genistein, a compound that helps turn down the genes for obesity and reduces your body’s ability to store fat.
Almonds are a great source of mono- and polyunsaturated fats, which can help lower your cholesterol and keep you slim. They also contain fewer calories than most other varieties of nuts (just 163 calories for 23), as well as plenty of fiber and vitamin E. According to a study in the International Journal of Obesity, people who added a daily serving of almonds to a low-calorie diet lost more weight than those who followed the same diet but ate a carb-heavy snack such as crackers instead.
Sure, nuts aren’t known for being low in calories, but they have an array of other properties—namely a high protein and fiber content—that makes them ideal for weight loss. A study published in the Journal of the American Heart Association, Circulation, found that consuming 1.5 ounces of almonds daily (as opposed to a carb-dense muffin) along with a heart-healthy diet, helped to improve cholesterol and lipid profiles among the research participants. The study also found that eating almonds reduces belly fat, too.
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.
Like a marathoner stretching before the big run, eating half a grapefruit before a meal can enhance your body’s fat-burning performance. A study published in the journal Metabolism found that this “warm-up” tactic can help whittle your middle—by up to an inch—in just six weeks! The scientists attribute the powerful effects to the grapefruits’ fat-zapping phytochemicals. The fruit can interact negatively with certain medications, so as long as you get the green-light from your M.D, plan to have half of a grapefruit before your morning meal and add a few segments your starter salads to reap the benefits.
