Alcohol has an energy content of 7 kcal/g of pure alcohol. However, there was no clear statistical correlation between alcohol consumption and body mass index in transversal as well as in longitudinal studies. This is related to the fact that alcohol stimulates NADPH oxidation, from NADH. Now, this is the couple NADH-ATP which produces energy, and thermogenesis. Thus alcohol is consumed more than it is stored. Futhermore, alcohol increases vasoactive processes (vasodilatation) and catecholamine secretion. Thus, resting energy expenditure and diet-induced thermogenesis increase.
纯酒精的能量含量为每克7千卡。然而，在横向和纵向研究中，酒精摄入量与体重指数之间均未发现明显的统计相关性。这与酒精刺激NADH进行NADPH氧化这一事实有关。现在，NADH - ATP这一组合会产生能量和产热。因此，酒精被消耗的量多于被储存的量。此外，酒精会增强血管活性过程（血管舒张）和儿茶酚胺分泌。因此，静息能量消耗和饮食诱导产热会增加。
