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.

Have a filling, healthy dinner every night. Finish your day with a dinner that is filling but will not overload your metabolism or create fat that is hard for your body to burn. Keep your dinner within 500 calories a meal and focus on a balance of protein, vegetables, and healthy fats. You can also rotate lunch and dinner options every day for variety.[8]

Dieters already know to steer clear of sugary cocktails and stick to vodka sodas at happy hour. But nixing booze altogether for a few weeks at a time could really help you jumpstart your weight loss efforts. A Journal of the Academy of Nutrition and Dietetics study found that alcohol causes people to eat an additional 384 calories per day on average, likely because booze makes us more sensitive to food aromas and less likely to resist indulgent fare.
Try a protein heavy meal like a bean tortilla with gazpacho. Warm up a two-ounce wheat tortilla in the microwave or on the stove and fill it with ½ cup cooked black beans, shredded lettuce, chopped tomatoes, two tablespoons shredded reduced-fat cheddar cheese, and half an avocado, sliced. Serve it with one cup of ready-made gazpacho or salsa. Finish with a one-ounce piece of dark chocolate for dessert.
Grapes were basically made to be snacked on, and always having some on hand could be great for your weight loss goals — a study published in PLOS Medicine found the sweet fruit can aid in shedding unwanted pounds. If you're trying to resist a calorie-heavy dessert, try tossing a bunch into the freezer so you can pop a few whenever you're craving something sweet.
Like peanuts, avocados contain metabolism-enhancing monounsaturated fats that have been shown to reduce hunger. In fact, a study in Nutrition Journal found that participants who ate half a fresh avocado with lunch reported a 40 percent decreased desire to eat for hours afterwards. What’s more? The trendy toast topping is also loaded with unsaturated fats, which seem to prevent the storage of belly fat, as well as satiating fiber and free-radical-killing antioxidants.

Making your sandwich with two slices of bread is so last year. Aid your slim down efforts by opting for whole-grain bread over white and preparing your sandwich “open-faced” style—the fancy name for kicking the top piece of bread to the curb. Doing so keeps about 70 to 120 calories off your plate. If losing some bread leaves your tummy rumbling, beef up your meal by munching on a cup of baby carrots or sugar snap peas. These pop-in-your-mouth veggies are loaded with fiber and water, which can help aid satiety and weight loss efforts.

We’ve already discussed how the color red may act as an appetite suppressant (hence the need for red dishes) but apparently that’s not the only color you should be taking note of as you prepare to eat. Per a recent study from Cornell University , diners actually serve themselves more food if the color of their food matches the color of their plate. In other words, if you’re eating from a white plate, you’re more likely to help yourself to more rice or pasta. Conversely, if your goal is to eat less, select plates that have high contrast with what you plan to serve for dinner.
