This mineral, found in all your body’s tissues, can be your metabolism’s BFF. Zinc helps your thyroid produce hormones that regulate your metabolism, says Cording. She recommends getting at least eight milligrams per day (that’s roughly the amount in three ounces of pumpkin seeds—which are a great source, by the way). Another way to get that metabolism-boosting goodness is to suck down some oysters. These fishy finger foods pack a nutritional punch and make you feel super fancy. “They’re low in calories, yet have a lot of protein and zinc,” says Cording. If you’re not into seafood, try lentils or chickpeas instead.
