Have you ever felt lost in the supplement section of your local health food store when trying to determine what type of protein is best for after your resistance training workout?
An article published in the American Journal of Clinical Nutrition found that the protein content of a meal will influence your appetite, your satiety (fullness), and caloric expenditure. All of which is why protein is very important in a weight loss diet.
Scientists found that Whey protein triggered greater post-meal caloric expenditure and fat use than soy or casein protein. Whey also reduced the increase in blood sugar following a high-carbohydrate meal greater than soy or casein protein.
Casein and soy were better at suppressing hunger than whey protein.
Each protein source has its advantages, and these sources should be considered when you are trying to lose weight.
