To delve into specifics, right here’s how macronutrients impression TEF:
- Fats: 9 energy per gram; TEF ranges from 0-5 %
- Carbohydrate: 4 energy per gram; TEF ranges from 5-15 %
- Protein: 4 energy per gram; TEF ranges from 20-30 %
This is among the causes a high-protein weight-reduction plan has a metabolic benefit and contributes to extended satiety. Similar with selecting minimally processed, complicated carbohydrates over easy carbohydrates.
