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.
A great source of calcium and important cancer-fighting compounds, broccoli also has loads of filling fiber and will set you back only 30 calories per serving. If eating this cruciferous veggie makes you bloat, try steaming it first, which makes it easier to digest while still preserving the cancer-fighting ingredients that could be lost when you boil or cook it in the microwave.
Since avocados are packed with nutrients and healthy fats that can stimulate weight loss, it’s no surprise that avocado oil acts in a similar fashion. When Penn State University researchers compared those who consumed monounsaturated-rich oils (like high-oleic canola oil or avocado oil) with those who consumed a flax-safflower oil blend, they found that those who used just three tablespoons of the monounsaturated-rich oil daily lost nearly two percent of their belly fat in just one month.
“The Dietary Guidelines recommend eating fish at least twice a week, and I think salmon is the perfect food to incorporate into your weekly meal plan,” says Rizzo. Salmon is rich in omega-3 fatty acids, which are good for your heart and can lower inflammation to aid in weight loss and combat water retention. Plus, eating healthy fat keeps you full. The bonus is that salmon has vitamin D to improve mood, she says.
Vending machines in particular have come under fire as being avenues of entry into schools for junk food promoters. However, there is little in the way of regulation and it is difficult for most people to properly analyze the real merits of a company referring to itself as "healthy." Recently, the Committee of Advertising Practice in the United Kingdom launched a proposal to limit media advertising for food and soft drink products high in fat, salt or sugar. The British Heart Foundation released its own government-funded advertisements, labeled "Food4Thought", which were targeted at children and adults to discourage unhealthy habits of consuming junk food.
These tiny fish are the unsung stars of the sea. With 23 grams of protein per can and a truckload of omega-3 and omega-6 fatty acids, they're an easy way to load up on nutrients. They're also low in mercury and high in calcium, making them a smart fish pick for pregnant women. If the flavor doesn't appeal to you, soak them in milk for an hour to help cut down on the fishiness.
Kamut is an ancient grain native to the Middle East that is an excellent source of heart-healthy omega-3 fatty acids, protein, and fiber, while simultaneously being low in calories. In fact, a half-cup serving of the stuff has 30 percent more protein than regular wheat and just 140 calories. What’s more? A study published in the European Journal of Clinical Nutrition found that eating Kamut reduces cholesterol, blood sugar, and cytokines (which cause inflammation throughout the body). Kamut’s ability to stabilize blood sugar and reduce inflammation make it a great weight loss staple, especially if it is used in place of nutritionally lacking refined grains.
You’ll want to add a pop of blue to your meals with this berry delicious fruit. “Research has linked eating a diet rich in fruits and non-starchy vegetables with weight loss, but I really like blueberries because they're packed with antioxidants and are available all year round in the frozen aisle,” says Rizzo. Add to yogurt, oatmeal, and salads, or use for sweetness in smoothies, sauces, and dressings.
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.
As long as this popular crunchy treat isn't doused in movie-theater butter, it makes an excellent weight-loss snack. Not only is popcorn high in fiber, it even delivers some protein. A 1-ounce serving of air-popped corn (about 3½ cups) has 4 grams of fiber, almost 4 grams of protein and clocks in at 110 calories. This combination makes it a snack with staying power. Popcorn is filled with air, so you get a pretty large portion without a lot of calories. You can eat 3 whole cups of popcorn for only 100 calories.
Greek yogurt is an extremely satiating breakfast or snack, thanks to its thick, creamy texture and a whopping 17 grams of protein (nearly three times more than is in an egg, in fact). A study from the journal Appetite found that people who ate a high-protein yogurt snack three hours after lunch felt fuller and ate dinner later than the other participants. And on top of that, other studies suggest that the acids produced during yogurt fermentation might help increase feelings of fullness.
