The postprandial phase has a fundamental role in metabolic regulation. In fact, being exposed to high levels of substrates such as glucose and fatty acids after food intake tends to increase the risk of cardiovascular disease. This is even more relevant in reference to the amount of hours in which the subject is in postprandial condition and therefore exposed to high concentrated substrates. Food intake, moreover, regulates gastrointestinal secretion of hormones which help balance between hunger and satiety, by regulating nutrients supply and peripheral substrate consumption.
