It is inappropriate to discuss human diets and protein intake on a percent of calories basis because protein needs are relatively constant regardless of calorie intake.

“it's inappropriate to talk about human diets and talk about protein intake on a percent of calories basis and the simple version of that is your calories fluctuate right but your need for protein doesn't not to that degree right so if you know you need thirty grams per meal of high quality of 90 grams a day whatever that number is then that's 90 grams regardless of whether you're eating 3000 calories or 2,000 or 4,000 calories a day right I mean so but that percentage would change dramatically so that's not appropriate”
