Abstract

OBJECTIVE:

To investigate the effects of a specific program to implement physical activity (fitness program) on weight loss maintenance, activity level and resting energy expenditure (REE).

DESIGN:

Observational study of subjects completing a behavioral program.

SUBJECTS:

In total, 200 overweight/obese subjects (36 males, aged 20-66 years; average BMI, 35.2 kg/m2). Program and measurements:The fitness program consisted of 12 bimonthly sessions, chaired by doctors and dietitians, involving groups of 8-12 subjects. Patients entered the program approximately 9 months after the end of behavioral treatment, during a weight loss maintenance period. The goal was set at a light-to-moderate daily physical activity (brisk walking), quantitatively measured by a pedometer; REE was measured before and after the fitness program by indirect calorimetry in a subset of patients.

RESULTS:

The fitness program restarted the process of weight loss in over 60% of subjects. At the end of the study, 84% of patients walked at least 5000 steps per day, compared with 24% at the beginning of the study. The probability of losing from 5 to 10% of initial body weight increased by 20% for any 1000 steps/day (OR, 1.20; 95% CI (confidence interval), 1.07-1.35), and that of losing more than 10% by over 30% (OR, 1.33; 95% CI, 1.19-1.49). REE increased significantly by 100 kcal/day (+7.5%), in spite of further weight loss (-1.8%).

CONCLUSION:

A specific fitness program in the weight maintenance phase after a behavioral program may significantly improve the long-term control of obesity.
