Effects of capsinoid ingestion on energy expenditure and lipid oxidation at rest and during exercise Abstract BACKGROUND: The thermogenic and metabolic properties of capsinoids appear to mimic those of the more pungent sister compound capsaicin. However, few data exist on how capsinoid ingestion affects energy expenditure in humans and no data exist on its interaction with exercise. We aimed to determine how ingestion of capsinoids affected energy expenditure, lipid oxidation and blood metaboli ...
