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.
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.
If you haven't jumped on the mushroom bandwagon yet, now's the time. Researchers from the University of Buffalo discovered that portobellos could help you lose weight thanks to their ability to regulate blood sugar (which can help prevent diabetes) and balance hormones. They also concluded that the fungus may help you exercise for longer periods of time, so use it as vegetarian-friendly burger base or toss into a tasty breakfast frittata.
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.
