Lentils
As a member of the super-nutritious pulse family, lentils—along with other seeds that grow within pods like chickpeas, white beans, and dried peas—are packed with protein and fiber, which increase satiety. They’re also a good source of iron; this is important because studies have shown that being deficient in the mineral could slow down your metabolism.
“Add lentils to salads or use in place of whole grains like brown rice,” says Cynthia Sass, MPH, RD, Health’s contributing nutrition editor. “They also make a great ‘bed’ for a serving of lean protein, along with a generous portion of veggies.”
