The objective of the present study was to determine the effectiveness of a soluble dietary fiber, NUTRIOSE^�, on body weight, body composition, energy intake and hunger in overweight Chinese men. The volunteers were randomized in double-blind fashion to 250 ml fruit juice supplemented with NUTRIOSE^� (Test, n = 60) or a maltodextrin (Control, n = 60) at a dosage of 17 g twice daily for 12 weeks. Body weight, body composition were performed at 0, 4, 8 and 12 weeks while daily energy intake and hunger were assessed every 3 days. Test subjects had reductions in body weight (1.5 kg, P < 0.001), body mass index (0.5 kg/m², P < 0.001) and body fat percentage (0.3%, P < 0.001) versus Controls. NUTRIOSE^� supplementation resulted in a lower daily energy intake (3,079 kJ/day, P < 0.001) with group differences noted as early as 3 days. Test subjects reported less hunger across the study period versus Controls (P < 0.01). NUTRIOSE^� supplementation for 12 weeks results in body composition improvements and reduces body weight, energy intake and hunger in overweight men.
