Abstract
Eating behaviour traits, namely Disinhibition and Restraint, have the potential to exert an effect on food intake and energy balance. The effectiveness of exercise as a method of weight management could be influenced by these traits. Fifty?eight overweight and obese participants completed 12 weeks of supervised exercise. Each participant was prescribed supervised exercise based on an expenditure of 500 kcal/session, 5 days per week for 12 weeks. Following the intervention, there was a significant reduction in mean body weight (3.26 � 3.63 kg), fat mass (FM: 3.26 � 2.64 kg), BMI (1.16 � 1.17 kg/m�) and waist circumference (WC: 5.0 � 3.23 cm).
Regression analyses revealed that a higher baseline Disinhibition score was associated with a greater reduction in BMI and WC, while Internal Disinhibition was associated with a larger decrease in weight, %FM and WC. Neither baseline Restraint nor Hunger was associated with any of the anthropometric markers at baseline or after 12 weeks. Furthermore, after 12 weeks of exercise, a decrease in Disinhibition and an increase in Restraint were associated with a greater reduction in WC, whereas only Restraint was associated with a decrease in weight. Post?hoc analysis of the sub?factors revealed that a decrease in External Disinhibition and an increase in Flexible Restraint were associated with weight loss. However, an increase in Rigid Restraint was associated with a reduction in %FM and WC.
These findings suggest that exercise?induced weight loss is more marked in individuals with a high level of Disinhibition. These data demonstrate the important roles that Disinhibition and Restraint play in the relationship between exercise and energy balance.
