Food-seeking behaviors can be driven by food-associated cues, and palatable food seeking in response to food cues is a risk factor for obesity development. Cue-induced food seeking increases following a period of abstinence, a behavioral phenomenon known as "incubation of craving," which may contribute to an individual's difficulty abstaining from palatable foods. Pharmacological and environmental manipulations have been employed to try and reduce incubation of craving, albeit primarily in drug abuse paradigms. The goal of this study was to determine whether forced exercise can attenuate incubation of high-fat food craving. Male Sprague Dawley rats learned to self-administer high-fat pellets (60%) in combination with a compound cue (light + tone). The influence of high-intensity interval exercise on the time-dependent increase in cue-induced lever responding was investigated 30 days after the first cue test. Rats exposed to exercise during abstinence did not express incubation of craving. The results suggest that high-intensity exercise can prevent the establishment of incubation of craving for foods high in fat and may reduce cue-induced maladaptive food-seeking behaviors that contribute to overeating and obesity.

D009765 Obesity A status with BODY WEIGHT that is grossly above the recommended standards, usually due to accumulation of excess FATS in the body. The standards may vary with age, sex, genetic or cultural background. In the BODY MASS INDEX, a BMI greater than 30.0 kg/m2 is considered obese, and a BMI greater than 40.0 kg/m2 is considered morbidly obese (MORBID OBESITY).
