For us, the issue is simply that we need carbs, protein, and fat, with quantities in that order to replace what we have burned. Most of us aren't trying to gain weight and we sure as heck don't want to mess up our livers. Most of us do just fine on the ordinary recs for quantities. So maybe the contention in that article is true, but who cares? We just want a positive nitrogen balance and we're good - but how do we know? I've read that the max was 40g. This might be quite interesting to track sprinters, but they probably already know it. I've messed around with increasing protein quantities, but then a blood test said that much was too much, dialed it back and fine now. Good to know though.
