True Protein has a range of whey protein powders that can be used for a variety of benefits, but particularly weight loss and muscle gain. When used as a supplement, whey protein is perhaps the best natural supplement for weight loss as it can help to improve muscle protein synthesis and promote the growth of lean tissue mass. There is also some evidence to show that drinking whey protein can help you to retain muscle mass and lose fat while trying to shed weight. It can help you to lose weight by keeping you fuller for longer, therefore preventing you from snacking or overindulging. True Protein’s WPI90, WPC80 and Pro-Define are all great supplements for weight loss and muscle gain.
