1. Whey Protein
Whey protein powder has been used for years as a natural appetite suppressant. It doesn’t affect blood sugar in the way that carbohydrates do and a stable blood sugar level helps speed up weight loss. Protein will keep you feeling fuller longer, with many diets based on this, such as ‘Atkins’, ‘South Beach’ and ‘The Zone’ – they all rely on protein to regulate blood sugar, encourage metabolism, and curb appetite. Protein also helps with muscle growth and larger muscles require more energy to function meaning more calories ‘burned’.
