Spice Things Up
Capsaicin, a compound in chili peppers, might rev up metabolism by about 5 percent, according to a study in the International Journal of Obesity. Allyl isothiocyanate, a compound in spicy mustard, can give your body a temporary bumb in metabolism, research has found.
Take Charge: Exchange the mayo on your turkey sandwich for spicy mustard, or add a tablespoon of mustard to homemade vinaigrette. Sprinkle crushed red pepper into spaghetti sauce, and add a teaspoon of chili powder to ground turkey for tacos.
