title: Emotions in overweight and normal-weight women immediately after eating foods differing in energy.
abstract: Immediate effects of low-, medium-, and high-energy foods on the emotional state of normal-weight and overweight women were studied experimentally. Nineteen normal-weight (body mass index [BMI]: 19-25 kg/m2) and 19 overweight women (BMI: 26-40 kg/m2) aged 18-40 years received samples of food that differed in energy content (low vs. medium vs. high energy) and rated their emotional state immediately after eating. Perceived characteristics of the foods and associations elicited by the foods were also obtained. Negative emotions (anger, fear, shame, and sadness) and sleepiness increased, while happiness decreased with energy of foods. Emotionally negative associations were more frequent, while positive emotions were less frequent the higher the energy content of the foods. Sadness, shame, fear, and sleepiness after eating high-energy food tended to be more intense in overweight women. Additional analyses demonstrated influences of eating habits, e.g., disinhibition. The higher the energy content of a food stimulus, the more it was viewed as "unhealthy" and "dangerous." It is suggested that immediate food-induced changes of emotions can be explained by activation of associative emotion networks.
