The Thermic Effect of food is defined as: the increment in energy expenditure above resting metabolic rate due to the cost of processing food for storage and use.

To figure out just how protein achieves this special effect, Mithieux and his colleagues fed rats a protein-enriched diet and measured metabolic changes.

One step in the healing process involves an enzyme that starts a metabolic effect and a signal transduction that triggers the process of skin repair and skin remodeling.
