When it comes to slimming down, two (or more) foods can be better than one. That’s because each has different nutrients that work together. As a team, they can help you fend off hunger, stay full longer, and burn fat or calories better than they would solo. A spinach or kale salad is low in calories and high in nutrients, but it can leave you wanting more. To make it more filling, top it with avocado. One study showed that people who had lunches that included the green fruit felt 23% more satisfied afterward than those who didn’t. That’s because it has a kind of good fat (monounsaturated) that staves off hunger. Bonus: Avocado also helps your body absorb more of the veggies’ disease-fighting antioxidants. Chicken breasts are known to be good for weight loss, and for good reason. One breast serves up 27 grams of protein for fewer than 150 calories. Protein takes longer to digest, and that can keep you full longer. Spice up this dinner staple with a rub or sauce made with cayenne pepper. It may boost your calorie burn and make you less hungry. A simple way to slim down: Eat the rough stuff. Simply adding more fiber to your diet can lead to weight loss. That’s because your body can’t break down fiber, so it slows down digestion and takes up space in your stomach. With 4 grams of fiber per cup, oatmeal can be a good source. Walnuts add another 2 grams, plus satisfying protein and crunch. Start your day with this protein-packed scramble. According to research in the Journal of the American College of Nutrition, people who had eggs for breakfast ate 22% fewer calories at lunch — and less the entire day — than those who had a bagel. Black beans and peppers make this morning meal even more filling, thanks to a double dose of fiber. Add a broth-based vegetable soup to your lunch or dinner. The liquid fills your stomach, leaving less room for higher-calorie foods. One study showed that people who started with soup ate 20% fewer calories during a meal. Stirring in beans, such as chickpeas or black beans, can give it more staying power because they’re high in protein and fiber. In fact, eating 3 cups of beans a week has been shown to boost weight loss. Too tired to hit the gym? This meal can help you out. Beef is rich in protein and iron, which your body uses to build red blood cells. They take oxygen to your organs, so falling short in those can zap your energy. broccoli is the perfect side, because its vitamin C helps your body take in iron. A half-cup of this veggie has 65% of all the vitamin C you need in a day. If you need a pick-me-up, brew some green tea. The low-calorie drink is packed with antioxidants called catechins, which may help you burn more calories and fat. Japanese scientists found that people who drank a bottle of tea high in catechins each day shed more fat after 2 weeks than those who didn’t. To make it even healthier, add a squeeze of lemon — it helps your body absorb them. Fish is often called “brain food,” but it’s also good for your waist. Its omega-3 fats may help you lose body fat, and salmon is a top source. Plus, one 3-ounce serving packs in 17 grams of protein. Serve it with a baked sweet potato for a filling yet light meal. A 5-inch-long spud has 4 grams of fiber and just 112 calories. Source
