20 Fat-Burning Secrets of The Grill

#5: Don't fear red meat

Just switch to lean cuts, which have a higher protein-to-fat ratio. A 2010 study in the New England Journal of Medicine found that a diet high in protein and low in processed carbs was the most effective for weight loss, and the B vitamins in meat help your body convert nutrients into energy. Another perk of protein? Your body also has to work harder to digest it, so when you eat, say, a steak, you stay fuller longer than you would if you ate a bagel. Try flank steak. With only 176 calories per 4-oz serving, flank is one of the leanest cuts at the meat counter, and it offers an impressive 24 grams of protein.
