Changes in body composition, cardiovascular disease risk factors, and eating behavior after an intensive lifestyle intervention with high volume of physical activity in severely obese subjects: a prospective clinical controlled trial.

ABSTRACT: We examined the effects of a 10-14-weeks inpatient lifestyle modification program, including minimum 90?min of physical activity (PA) five days/week, on body composition, CVD risk factors, and eating behavior in 139 obese subjects (BMI 42.6 ± 5.2?kg/m²). Completion rate was 71% (n = 71) in the intensive lifestyle intervention (ILI) group and 85% (n = 33) among waiting list controls. Compared to controls body weight (-17.0 (95% CI:?-18.7, -15.3)?kg, P < 0.0001), fat mass (-15.2 (95% CI:?-17.4, -13.1)?kg, P < 0.0001), fat free mass (-1.2 (95% CI:?-2.2, -0.2)?kg, P = 0.016) and visceral fat (-86.6(95% CI:?-97.4, -75.7)?cm², P < 0.0001) were reduced in the ILI-group after 10-14 weeks. Within the ILI-group weight loss was -23.8 (95% CI:?-25.9, -21.7)?kg, P < 0.0001 and -20.3 (95% CI:?-23.3, -17.3)?kg, P < 0.0001, after six and 12 months, respectively. Systolic BP, glucose, triglycerides, and LDL-C were reduced, and HDL-C was increased (all P ? 0.006) after 10-14 weeks within the ILI group. The reduction in glucose and increase in HDL-C were sustained after 12 months (all P < 0.0001). After one year, weight loss was related to increased cognitive restraint and decreased uncontrolled eating (all P < 0.05). Thus, ILI including high volume of PA resulted in weight loss with almost maintenance of fat-free mass, favorable changes in CVD risk factors, and eating behavior in subjects with severe obesity.
