First and foremost, YOU DON'T NEED PROTEIN SUPPLEMENTS TO LOSE WEIGHT.
Yes, protein has a very important role in weight loss however consuming processed protein supplements may actually lead to weight gain rather than weight loss! Why? Because typically they are still high in calories, despite being high in protein (some aren’t even that great), they may be filled with other things such as fats and sugar derivatives. The notion that the more protein you eat the more muscle you gain is false! If you eat protein in excess it is simply stored as FAT.
Back to protein and weight loss. When trying to lose weight, protein is certainly required in moderate amounts to compensate for maintaining our muscle mass as we try to introduce a lower overall calorie intake to stimulate weight loss. The consumption of regular and appropriate portions of protein can help stimulate a faster metabolism as protein actually requires the body to use energy to metabolise and digest it compared to carbohydrates and fats. Ensuring protein is in each of our meals and/or snacks also helps to satisfy our hunger and keep us fuller for longer between meals.
