hi, @Sparrow24. glad that you’re feeling good
90% carb 10% fat makes no sense, you do need protein. ;) where in “eat for heat” does it talk about that? a quick search for 90% didn’t bring it up. can you quote a sentence?
my long dieting experience has shown me that most rapid, drastic changes in diet make me feel uncomfortable for a while — my body doesn’t like quick changes.
also, eating less than the calories you estimate you require on a single day is not a problem; sometimes you just don’t feel like eating as much. the general idea is to listen to your body when it comes to hunger signals. “not enjoying it” is a pretty good warning signal.
i’d recommend a more gradual shift.
