Study under review: Capsaicin-induced satiety is associated with gastrointestinal distress but not with the release of satiety hormones
Do you love the burn of spicy food, or prefer to take it mild? The heat of peppers, hot sauces, and many other pepper-based spicy foods comes from a chemical called capsaicin. In addition to gastronomical pleasures, there is research that suggests consumption of capsaicin can promote weight loss. The mechanism by which this occurs is not well defined. Some researchers have suggested that capsaicin has a direct effect on how the body expends energy, either through the activation of brown adipose tissue (generating heat as a byproduct) or through increases in fat oxidation. Other researchers hypothesize that there is an effect on various biological responses like catecholamines (including epinephrine and norepinephrine, which can suppress appetite) or insulin. A third hypothesis is that foods containing capsaicin work to decrease appetite, and thus overall caloric intake.
