Actually, protein intakes above 20% are not recommended based on current research, even for weightlifters. High protein intakes stress your kidneys and do not result in greater muscle gain which happens when you work a muscle to do more work than it is currently capable.
When I enter 35% for my protein intake in your Healthy Body Calculator®, I get an error message that 35% is too high. I am a weightlifter and this is not ‘unreasonable’. Please fix this or find a way to enter whatever values we would like. I like your page and would like to keep using it.
