Gender-assigned-at-birth additionally issues, with males typically possessing increased BMRs because of increased common muscle mass.

To delve into specifics, right here’s how macronutrients affect TEF:

Fats: 9 energy per gram; TEF ranges from 0-5 p.c
Carbohydrate: 4 energy per gram; TEF ranges from 5-15 p.c
Protein: 4 energy per gram; TEF ranges from 20-30 p.c

This is likely one of the causes a high-protein food regimen has a metabolic benefit and contributes to extended satiety. Similar with selecting minimally processed, complicated carbohydrates over easy carbohydrates.
