Researchers at Wake Forest University found that "a high-protein, low-calorie diet helped overweight older adults lose more pounds, maintain more muscle mass, improve bone quality, and lose 'bad' fat."
A federal study put 12 healthy women on a high-protein diet. The result? They experienced "greater feelings of fullness and less hunger" than the group that ate a lower-protein diet.
Germany's Carl von Voit, an early nutritional scientist (and dietician), believed that protein was the most important nutrient for maintaining the structure of the body.
Dutch chemist Gerardus Johannes Mulder described proteins for the first time.
