FOOD GROUP PREFERENCES AND ENERGY BALANCE IN MODERATELY OBESE POSTMENOPAUSAL WOMEN SUBJECT ED TO A BRISK WALKING PROGRAM

Résumé

The main objective of this study was to examine the effects of a 16-week walking program on food group preferences and energy balance of 156 sedentary postmenopausal women, 50 to 65 years-old, whose body mass index ranged from 29 to 35 kg/m2. Women were subjected to 3 sessions/week of 45 min-walking at 60 % of heart rate reserve. Total energy intake, TEI and food groups preferences (3day dietary record), total energy expenditure, TEE (3-day physical activity diary), cardiorespiratory fitness, CRF (2-km walking test), anthropometry and body composition (bioimpedance) were measured before and after our walking program. The modest increase in TEE of 151±24 kcal/day (mean ± SD) (p<0.0001) leads to body weight and fat mass losses as well as to waist girth reduction (p<0.0001). However, TEI remained unchanged despite a slight decrease in carbohydrate intake (-1.0 ± 0.5 % TEI; p<0.05) vs. a minor increase in protein intake (0.7±0.3 % TEI; p<0.05). Analysis of food records revealed a decreased consumption of fruits (-0.18±0.08 servings/day; p<0.05), sweet and fatty foods (-0.23±0.09 servings/day; p<0.01), but an increased oil consumption (0.32±0.08 servings/day; p<0.0001) after walking. Women with the highest body weight loss showed the greatest reduction in fruits (-0.43±0.16 servings/day; p<0.05), sugar and sweet foods (-0.098±0.22 servings/day; p≤0.05) as well as fatty foods (-0.31±0.21 servings/day; p<0.05). Women characterized by the greatest fat mass loss showed the highest decrease in fatty food consumption (-0.20±0.19 servings/day; p<0.05). A similar analysis taking into account tertiles of waist girth or CRF changes did not reveal changes in food group preferences. Our data indicate that moderate physical activity leads to minor changes in food group comsumption but does not modify TEI, thus maintaining a negative energy balance in obese postmenopausal women.
