Flexible Eating Behavior Predicts Greater Weight Loss Following a Diet and Exercise Intervention in Older Women

ABSTRACT Eating behaviors (cognitive restraint, flexible and rigid restraint, disinhibition, hunger) have been associated with obesity and weight loss success in middle-aged individuals, but little is known about these relationships in older adults. This study examined relationships between eating behaviors and weight loss in overweight/obese older women (n = 61; 69 ± 3.6 years; body mass index = 31.1 ± 5.0 kg/m2) completed a 6-month behavioral weight loss intervention. Baseline, postintervention, and change measures of eating behaviors (51-items Three-Factor Eating Questionnaire) were assessed for relationships with weight loss. In the final regression model, an increase in flexible restraint accompanied by a decrease in rigid restraint predicted greater weight loss (adjusted R2 = 0.21, Model F (4, 56) = 4.97, P < 0.01). No associations were found with disinhibition or hunger and degree of weight loss (all P > 0.05). Results suggest encouraging a flexible approach to eating behavior and discouraging rigid adherence to a diet may lead to better intentional weight loss for overweight and obese older women.
