Whey protein outperforms soy in helping adults lose weight, say US researchers

摘要

To better understand the relationship between protein intake and weight loss, researchers at USDA's Agricultural Research Service (ARS) conducted a rigorous human intervention trial comparing proteins in overweight and obese adults and published their results in the August 2011 edition of The Journal of Nutrition. The 73 adult subjects with a body mass index (BMI) between 28 and 38kg/m2 consumed either whey (milk) protein, soy protein (each with about 104g protein) or carbohydrate supplements for 23 weeks. By the end of the study, "body weight of the group consuming the whey protein was significantly (2%) lower than that of the group consuming the carbohydrate treatment" and body fat mass was 2.3kg lower.
