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 d/week for 12-weeks. Following 12-weeks of exercise 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/m2)
and waist circumference (WC: 5.0 ± 3.23 cm). Regression analyses revealed 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 or Hunger were
associated with any of the anthropometric markers at baseline or after 12-weeks. Furthermore, after
12-weeks of exercise, a decrease in Disinhibition and 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 a decrease in External Disinhibition and 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.
