Evening everyone. Wondering what the thinking is on using whey protein powder shakes as a replacement for meals when trying to lose weight. It's low in everything and in a 31g scoop packs 26g protein. I realise it's normally associated with building muscle mass but was wondering how useful it might be as part of a low carb diet as in 5:2 or the 8 week blood sugar diet where Dr Mosley talks about the option of using shakes.
