Proteins are much more satiating than carbohydrates and fats. While whey protein (whey) is absorbed quickly and is digested also quickly, the slow release rate of casein makes you feel full for longer because it is digested slowly. Both proteins are suitable for supplying the body with protein during a diet, provided you eat a balanced and varied diet. If you consume around 20-30 grams of protein per meal or between 0.9 and 2.4 g of protein per kg of body weight per day, depending on your age, sporting ability and other goals (make sure it has a high biological value!), you can achieve a high level of satiety, avoid cravings and reduce unwanted snacking.
