Negative emotions can influence food intake. Leptin (an anorectic hormone) levels may change in response to psychological stressors. This study aimed to explore the relationship between leptin and food intake triggered by negative emotions in overweight women. Two groupswere studied: normal weight women (n = 21) and overweight women (n = 23). Both groups were exposed to videos to stimulate negative and neutral emotions followed by application ofthe Subjetive Analog Scale. Plasma leptin levels were evaluated before and after exposure to the videos. Subsequently, a brunch containing sweet and salty foods was offered to simulatea high food availability environment. Results show that when exposed to negative emotions there was an increase in food intake (normal weight: p=.010 / overweight: p=.005). There was no change in plasma leptin levels in normal weightand overweight women. Negative emotions promotedan increase in energy intake in both groups. The results reinforce the integration of biopsychosocial aspects involving emotions and food intake.

负面情绪会影响食物的摄入量。瘦素（一种厌食激素）水平可能会因心理压力而改变。本研究旨在探讨瘦素与超重女性负面情绪引发的食物摄入之间的关系。研究了两组：正常体重女性（n  = 21）和超重女性（n  = 23）。两组都接触视频以激发负面和中性情绪，然后应用主观模拟量表。在暴露于视频之前和之后评估血浆瘦素水平。随后，提供包含甜味和咸味食物的早午餐以模拟高食物可用性环境。结果表明，当暴露于负面情绪时，食物摄入量会增加（正常体重：p=.010 / 超重：p =.005)。正常体重和超重女性的血浆瘦素水平没有变化。负面情绪促进了两组能量摄入的增加。结果加强了涉及情绪和食物摄入的生物心理社会方面的整合。
