Abstract

Introduction: Chronic dieting can result in characteristic metabolic adaptations such as a suppression of resting metabolic rate (RMR). Previous research has focused on health outcomes related to metabolic suppression in female athletes, which include impaired menstrual and bone health. The study purpose was to assess the relationship between metabolic suppression and body composition, fitness, and eating behavior traits in exercising men.

Approach: Cross-sectional study comparing exercising men who display evidence of metabolic suppression (MS) and a control group (Con). RMR was used as a surrogate marker of metabolic suppression.

Results and Discussion: When compared to Con, MS had a higher body fat percentage (p=0.06), consumed more calories (p=0.04) and were in a positive energy balance (p=0.04), scored higher on eating behavior scales related to overeating such as uncontrolled eating (p=0.04), and had a higher incidence of injuries (p=0.03). Future long-term studies are needed to determine a) the underlying factors and b) the long-term risks associated with metabolic suppression.
