Your body makes peptides. They’re strings of amino acids, which are the “building blocks” of proteins. But a peptide doesn’t have as many amino acids as a protein does.
Peptides are short chains of amino acids linked together by peptide bonds. Amino acids, when joined together in a specific sequence, they form peptides. Peptides can range in length from just a few amino acids to several dozen.
When you consume food, your body requires energy to break down the food, absorb the nutrients, and store or utilize them for various metabolic processes.
Diet-induced thermogenesis (DIT), also known as the thermic effect of food (TEF) or specific dynamic action (SDA), refers to the increase in energy expenditure that occurs during the digestion, absorption, and metabolism of food. It is one of the components that make up the total energy expenditure of an individual.
