Is there a difference between whey protein concentrate and whey protein isolate?
Yes, there is an enormous difference. Whey protein isolate is the purest form of whey protein. It contains 90% or more protein and very little (if any) fat and lactose. Whey protein concentrate are loaded with fat and lactose, and as the protein level in whey protein concentrate decreases the amounts of fat and/or lactose usually increase. For those trying to lose weight, protein is their best friend. Not only can protein supplements be used as low calorie snacks or meal replacements, but it helps level your hormonal landscape. Protein raises Glucagon levels (fat burning hormone) and reduces Ghrelin levels (a hormone that stimulates appetite).
