Biology

The amount of energy that your body uses for digestion varies depending on how much food you consume. Generally, it is estimated that the digestion process requires 10-15% of your body’s daily energy expenditure. This means that your body will use approximately 150-225 calories per day just for the digestive process. Digestion uses energy to break down and absorb macronutrients (carbohydrates, fats, and proteins) that can then be used for energy or stored for future use.
