 Drive for leanness (DL), a motivating interest in having low body fat and toned muscles, is hypothesized to be less maladaptive than drives for thinness (DT) and muscularity (DM), which has implications for its inclusion in eating- and health-related prevention and treatment programs; however, little research has explored this hypothesis. The current study investigated DL’s uniqueness from these other drives, as well as simultaneously explored if associations of DL and a range of health-related outcomes supported that it may be less maladaptive than DT and DM.
