The anabolic effects of resistance exercise are amplified by amino acids or protein.
Higher protein/lower carbohydrate diet favorably affects body mass and composition independent of energy intake ("metabolic advantage").
High protein intake plays a key role in weight management, through (i) increased satiety, (ii) its effect on thermogenesis, (iii) body composition, and (iv) decreased energy efficiency.
Prospective epidemiologic observations indicate that higher protein intake is associated with increased bone mineral mass and reduced incidence of osteoporotic fractures.
Exchanging protein for carbohydrate significantly reduces LDL cholesterol ("bad cholesterol") and triacylglycerol (harmful blood lipid) levels and increases HDL cholesterol ("good cholesterol").
Higher consumption of protein has been inversely associated with blood pressure in several studies, i.e., protein decreases blood pressure.
It is possible to improve blood sugar control in people with type 2 diabetes by increasing protein intake while decreasing carbohydrate intake (and without weight loss).
Higher protein intake has no adverse effects on healthy kidneys, liver or fluid status.
