Why It's a Must Have: Greek yogurt is an excellent source of protein, says Dr. Brock. Protein helps to level out blood sugar and helps you stay full, which can help prevent overeating. “Your best bet for revving up a sluggish metabolism is to eat some protein with each meal, and low-fat Greek yogurt should be a go-to food.” Another bonus? If you are stressed, snacking on some could help boost your mood too. It’s rich in tryptophan, an amino acid that is a precursor to the feel-good brain chemical serotonin, which the brain uses to make neurotransmitters that help you relax, explains Dr. Brock.
Budget Bonus: Skip the flavored varieties -- buy it plain and then add fresh fruit for sweetness if desired, recommends Dr. Brock. “Flavors cost more and are usually higher in sugar and calories.”
