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.
Drinking enough water can help you stay slim, too. Research from the American Chemical Society in Boston found that having two 8-ounce glasses of water before a meal while also reducing portion sizes could help you lose weight and keep it off. Not to mention, water fills you up, curbing your appetite: "In addition to slightly boosting your metabolism, drinking water before meals has been shown to help you eat less without trying," says Sass.
Not all the nutrients and other substances that contribute to good health have been identified, so eating a wide assortment of healthy whole foods like fruits and vegetables helps ensure that you get all of the health-promoting benefits that foods can offer. If your diet, day after day, consists of the same half dozen foods, it could fall short. In addition, varying your food choices will limit your exposure to any pesticides or toxic substances that might be present in particular foods.
Losing weight isn't all about exercise – what you eat matters too. But nobody wants to eat diet food that makes them feel like they're going to gnaw their arm off before dinner. That's why registered dietitians say it's important to up your intake of veggies, grains, nuts, and other foods that are full of fiber, protein, and other pound-dropping nutrients. These options will help you prevent cravings and keep you full straight through your usual afternoon snack.
