Eating enough what? Protein or carbs?

In my mind that COULD work but it may not. I've considered it, i.e. upping carbs to counter a lack of protein, but the keto calculator ( http://keto-calculator.ankerl.com/ ) does not account for trading carbs with protein. When I asked teaser (a good sounding board) he was not sure. The question revolves around how the muscles are limited, I think. If the limit is glucose energy, then carbs and protein can be exchanged. If the limit is muscle recovery then the only protein will suffice, I think........

Your question though was about nausea. Again, the only experience I had was that it took a few days for my gut to get acclimated to increased protein when I consciously increased my intake.
