health.thermic-effect-of-food Calculator
Calculates the thermic effect of food (TEF) — the energy used to digest and metabolise each macronutrient — as a proportion of daily caloric intake. Protein has the highest TEF (20–30%); fat has the lowest (0–3%) — TEF typically adds 100–200 kcal to daily energy expenditure.
Inputs
Protein Calories
Energy content in kilocalories (kcal). 1 kg of body fat stores roughly 7,700 kcal.
Carb Calories
Energy content in kilocalories (kcal). 1 kg of body fat stores roughly 7,700 kcal.
Fat Calories
Energy content in kilocalories (kcal). 1 kg of body fat stores roughly 7,700 kcal.
Results
thermic effect of food TEF (kcal)
Reference formula or conversion factor shown for context.
TEF as % of total calories
The combined total across all inputs and components.
