I’m talking only with regard to maintaining good glucose stability. In those who are very insulin resistant, protein can be a problem. I realise that those for whom it isn’t a problem like to brush this off, but for those who have experienced it, it is very real. Demand driven or otherwise. That doesn’t really cut the mustard if your liver is shedding its burden willy nilly, aided by unused amino acids.
All I’m saying is that some extremely insulin resistant people should exercise caution if wanting to use extra protein in order to gain weight.
