We've all heard the myth that extra protein builds more muscle. In fact, the only way to build muscle is through exercise. Bodies need a modest amount of protein to function well. Extra protein doesn't give you extra strength. According to the U.S. Department of Health and Human Services:
Teenage boys and active men can get all the protein they need from three daily servings for a total of seven ounces.
For children age 2 to 6, most women, and some older people, the government recommends two daily servings for a total of five ounces.
For older children, teen girls, active women, and most men, the guidelines give the nod to two daily servings for a total of six ounces.
Everyone who eats an eight-ounce steak typically served in restaurants is getting more protein that their bodies need. Plus they're getting a hefty amount of artery-clogging saturated fat as well.
