18 Foods that Boost Your Metabolism
How much protein do you need? New research suggests that many of us may need more protein than we realize. The current RDA is 0.8 g of protein per kilogram of body weight, but several studies have found that 1 to 1.2 g may be more protective against age-related muscle loss.
Use this formula from Caroline Apovian, MD, to determine the minimum amount of protein you should eat daily to offset muscle loss--and protect your metabolism--while you lose weight.
STEP 1 Estimate your ideal weight. "If you're a woman, start with 100 pounds for the first 5 feet in height, and add 5 pounds for every extra inch," says Dr. Apovian. "For men, it's 106 pounds for 5 feet in height, plus 6 pounds for every additional inch. However, if your ideal weight is less than 120 pounds, don't eat less than 82 g of protein daily."
STEP 2 Ideal Weight (in lb) ÷ 2.2 = Ideal Weight (in kg)
STEP 3 Ideal Weight (in kg) × 1.5 = Daily Protein Goal (in g)
Now that you know how much you need, check out these metabolism-boosting protein-packed foods!
