Eggs are rich in high-quality protein, fats and essential nutrients, like vitamin D and choline. It's the protein, and the time of day we tend to eat them, that especially makes them a powerhouse for weight loss. Eating a high-protein breakfast promotes weight loss, because protein increases satiety while regulating hunger and appetite hormones, helping fend off your hunger until lunchtime. One study found that eating eggs for breakfast left people feeling more satisfied than those who had bagels—which helped them eat less throughout the day.
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.
All beans are high in fiber, which is your friend when you're trying to lose weight because it helps you feel fuller longer, thus controlling hunger. Eating beans and legumes has also been linked with various other health benefits, including lowering blood pressure, reducing LDL cholesterol and reducing risk of cardiovascular disease. Beans are fairly low in calories and deliver protein as well. Try them in homemade veggie burgers, soups and salads.

Dairy products are the best sources of calcium, but you can also get it from fortified foods as well as canned salmon, sardines, dark leafy greens, and most tofu. If you can’t get the recommended 1,000 to 1,200 milligrams a day from food, take a calcium supplement. It’s hard to consume enough vitamin D from foods (the RDA is 600 to 800 IU a day, though other experts advise more). Thus, many people—especially those who are over 60, live at northern latitudes, or have darker skin—should consider taking a supplement.
