Meta- analysis of BMI values at end of trial showed no statistically significant difference in BMI change by use of 25[OH]D supplementation .
Based on existing published trials , oral 25[OH]D supplementation does not significantly impact BMI change
The impact of 25-hydroxyvitamin D ( 25[OH]D ) supplementation on weight change remains controversial .
The objective of this study was to summarize the effects of 25[OH]D supplementation ( cholecalciferol or ergocalciferol ) on BMI change through a meta- analysis of published clinical trials .
Effects of a 16-month randomized controlled exercise trial on body weight and composition in young, overweight men and women: the Midwest Exercise Trial.
BACKGROUND In light of the current obesity epidemic , treatment models are needed that can prevent weight gain or provide weight loss . We examined the long-term effects of a supervised program of moderate-intensity exercise on body weight and composition in previously sedentary , overweight and moderately obese men and women . We hypothesized that a 16-month program of verified exercise would prevent weight gain or provide weight loss in the exercise group compared with controls . METHODS This was a r and omized controlled efficacy trial . Participants were recruited from 2 midwestern universities and their surrounding communities . One hundred thirty-one participants were r and omized to exercise or control groups , and 74 completed the intervention and all laboratory testing . Exercise was supervised , and the level of energy expenditure of exercise was measured . Controls remained sedentary . All participants maintained ad libitum diets . RESULTS Exercise prevented weight gain in women and produced weight loss in men . Men in the exercise group had significant mean + /- SD decreases in weight ( 5.2 + /- 4.7 kg ) , body mass index ( calculated as weight in kilograms divided by the square of height in meters ) ( 1.6 + /- 1.4 ) , and fat mass ( 4.9 + /- 4.4 kg ) compared with controls . Women in the exercise group maintained baseline weight , body mass index , and fat mass , and controls showed significant mean + /- SD increases in body mass index ( 1.1 + /- 2.0 ) , weight ( 2.9 + /- 5.5 kg ) , and fat mass ( 2.1 + /- 4.8 kg ) at 16 months . No significant changes occurred in fat-free mass in either men or women ; however , both had significantly reduced visceral fat . CONCLUSIONS Moderate-intensity exercise sustained for 16 months is effective for weight management in young adults
