Background: Previous research showed that weight loss in response to weight management program is influenced by total energy intake and water consumption. Whether or not purified water affects weight management is currently unknown. Methods: An intervention study of 29 middle-aged obese women who reported < 1L/day drinking water at baseline was carried out in Yaounde, Cameroon. Participants were randomly assigned to one of the two groups: (i) hypocaloric diet + physical activity + reverse osmosis infrared filtered water (ROIFW), and (ii) hypocaloric diet + physical activity. Weight, waist circumference and body fat were assessed at baseline, 4, 8, 12, 16, 20, 24, and 28 weeks. General Linear Model procedure of repeated measurements was used to determine whether weight loss as well as changes in waist circumference and body fat differ between the two study groups. Results: After 12 weeks from baseline, women in both groups lost an average of 7% of their initial body weight. A statistically significant difference in weight loss was observed between the ROIFW (7.9 kg; 95%CI: 6.5-9.3) and control (5.5 kg; 95%CI: 3.7-7.4; P=0.03) groups. No significant difference was apparent in both waist circumference and body fat throughout the intervention although women in the ROIFW group experienced higher reduction. Conclusion: Our results suggest that obese women using ROIFW may augment weight loss when combined with hypocaloric diet and physical activity. More extensive data are warranted to confirm these findings, as well as to address issues of optimal volume and timing of ROIFW consumption.
