Cheese isn’t traditionally thought of as something you consume to encourage weight management, but calcium-rich Parmesan, when eaten in moderation, can help stave off sugar cravings that can easily lead to weight gain. How does that work, you ask? The native Italian cheese contains the amino acid tyrosine (a building block of protein) which has been shown to encourage the brain to release dopamine without any unhealthy insulin spikes. What’s more? The combination of calcium and protein found in dairy products such as Parmesan has been found to increase thermogenesis—the body’s core temperature—and thus boost your metabolism.
Yogurt is protein-packed and full of probiotics, which are good for gut health and may help your weight-loss efforts. Your gut health can impact your weight, and eating more fiber and probiotics helps keep your gut bacteria happy, which can be good for your metabolism (read more about your gut-weight connection). Go Greek for more protein; plus, research from Appetite found that consumption of Greek yogurt was associated with reduced appetite and increased satiety. Just keep an eye on added sugars in flavored yogurts, which only add calories. Instead, use fresh fruit to sweeten plain yogurt.
Going gluten-free may be a popular trend, but unless you're actually gluten-intolerant or have celiac disease, plenty of reasons exist to continue eating whole grains. They're a tasty way to fill up on both soluble and insoluble fiber, which help you feel full for longer and keep bowel movements regular (oats, barley, and bulgur are especially high sources). Whole grains can also help prevent weight gain: in one study, women who ate whole grains like wheat germ and dark bread had a 49% lower risk of "major" weight gain over time.
As found in nuts, seeds, fish, avocados, and plant oils. You should consume these high-fat foods in place of other high-calorie foods; otherwise, you’ll be adding excess calories to your diet. For instance, substitute olive or canola oil for butter, and nuts for chips. Fatty fish may reduce the risk of heart disease and have other benefits, attributed at least in part to their omega-3 polyunsaturated fats.
This often over-looked gem is loaded with protein, filling fats, and calcium to help you build and repair muscles, which can aid in weight loss. “It's fabulous with fruit, on whole grain toast, oatmeal or salads, but the super high protein content [13 grams per 1/2 cup serving!] helps to keep you full in between meals,” says Harris-Pincus. You can also use it in smoothies, in eggs, or in pancake batter. Just be sure to check labels and find a product that’s low in sugar.
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.
You may not think of them as a weight-loss food, but eggs are packed with protein, which helps curb your appetite. One study found that overweight women who ate eggs for breakfast were able to lose twice as much weight as women who started their days with bagels. And egg whites in particular are a good source of branched-chain amino acids, which help keep your metabolism running smoothly.
For a 2,000-calorie daily diet, aim for 2½ cups of vegetables and 2 cups of fruit a day. If you consume more calories, aim for more produce; if you consume fewer calories, you can eat less. Include green, orange, red, blue/purple, and yellow vegetables and fruits. In addition to the fiber, the nutrients and phytochemicals in these foods may help protect against certain types of cancer and other diseases. Legumes, rich in fiber, can count as vegetables (though they have more calories than most vegetables). For more fiber, choose whole fruits over juice.
