Thermic Effect of Food کا حساب کیسے لگائیں
Thermic Effect of Food کیا ہے؟
The thermic effect of food (TEF) is the energy expended digesting, absorbing, and metabolising nutrients. Protein has the highest TEF (20–30%); carbohydrates moderate (5–10%); fat lowest (0–3%). TEF accounts for roughly 10% of total daily energy expenditure.
