Whey protein is said to support thermogenesis or calorie-burning. According to a study published in the journal ‘Clinical Nutrition’, high protein diets have been repeatedly linked to better weight loss outcomes when compared with other lower protein diets, through its effect on both components of energy balance: Energy expenditure and food intake. Whey protein has a metabolic advantage over casein and soy protein, the advantage being a higher diet induced thermogenesis for whey (14%) than casein (12%) and soy (12%).
Other research suggests that whey protein can also improve cholesterol levels, lower blood pressure, and minimise the risks of cardiovascular diseases. Says a study that appears in the journal ‘Geriatrics & Gerontology International’, whey protein supplements help prevent sarcopenia among healthy older women when taken after resistance exercises. Moreover, when supplemented with whey protein, exercise helps increase skeletal muscle mass, enhance grip strength, and improve gait speed.
