Self-selected food intake of 15 reduced-obese women living in a metabolic ward was studied for 14 consecutive days to determine the effect of exercise and other metabolic and behavioral variables on energy intake. A choice of prepared food items were offered at breakfast, lunch and dinner, and a variety of additional food items were available continuously 24 h/day. Subjects performed either moderate intensity aerobic exercise (A-EX) (n=8) expending 354±76 kcal/session or low intensity resistance weight training (R-EX) (n=7) expending 96±4 kcal/session, 5 days/week. Mean energy intakes (kcal/day,±SEM) of the exercise groups were similar: 1867±275 for A-EX, 1889±294 for R-EX. Mean energy intakes of individuals ranged from 49 to 157% of the predetermined level required for weight maintenance. Resting metabolic rate per kg0·75and the Eating Inventory hunger score contributed significantly to the between subject variance in energy intake, whereas exercise energy expenditure did not. Regardless of exercise, eight women consistently restricted their energy intake (undereaters), and seven others consumed excess energy (overeaters). Overeaters were distinguished by higher Eating Inventory disinhibition (p=0·023) and hunger (p=0·004) scores. The overeaters» diet had a higher fat content, 34±1 energy %, than that of undereaters, 27±1 energy % (p=0·007). Also, overeaters took a larger percentage of their daily energy intake in the evening, 13±2%, compared to undereaters, 7±1% (p=0·005). We conclude that the Eating Inventory is useful for identifying reduced-obese women at risk of overeating, and these individuals may benefit from dietary counselling aimed at reducing fat intake and evening snacking.
