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.
Long live the sweet potato, savior to all people looking to cut back on carbohydrates in a healthy way. "Carbohydrates are your body's preferred source of energy," Abbey Sharp, R.D. with Abbey’s Kitchen, told SELF in a previous article. "Enjoying more fiber-rich complex carbs like whole grains, fruits, and vegetables will be more conducive to weight loss and health in general than eating refined ones, which can spike blood sugar quickly." That’s where sweet potato comes in, serving up 41 grams of healthy carbs and 7 grams of fiber (keep the skin on!) per cup.
Apples contain pectin, an ingredient that naturally slows digestion and encourages feelings of fullness. Studies show that eating a whole apple with your meal (as opposed to apple juice or applesauce) is a natural appetite suppressant, helping you consume fewer overall calories without feeling deprived. Sass likes using shredded apple in slaws and stir-fry, or mixing them into burger patties to add moisture.
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.
These foods—notably vegetables, fruits, legumes, and whole grains—should supply about 20 to 35 grams of dietary fiber a day, depending on your calorie needs. (Aim for 14 grams of fiber for every 1,000 calories, as advised by the Dietary Guidelines for Americans.) Fiber slows the absorption of carbohydrates, so they have less effect on insulin and blood sugar, and it provides other health benefits. Try to fill three-quarters of your plate with produce, legumes, and whole grains—leaving only one-quarter for meat, poultry, or other protein sources.
Carbs are not the nutritional Voldemort. Actually, certain healthy carbs can help you lose weight—and air-popped popcorn is one of them. “Portion-wise, it has a lower calorie per unit volume than many other snacks,” Lauren Harris-Pincus, M.S., R.D.N., and owner of Nutrition Starring You, told SELF in a previous article. You get more bang for your caloric buck, and since popcorn is made up of complex carbs, it’ll digest more slowly, keeping you fuller longer.
