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 .
Calcium intake and the outcome of short-term weight management.
Experimental and epidemiological studies suggest that calcium intake is inversely related to weight gain .  Calcium of dairy origin has been shown to be more effective in promoting weight loss . However , clinical studies yielded controversial results concerning the role of calcium intake in weight change . The aim of this study was to ascertain whether the addition of calcium can affect the outcome of 3-week weight management ( WM ) with a hypocaloric diet characterized by a decreased calcium intake . Overweight/ obese women ( n=67 ; BMI 32.2+/-4.1 kg/m(2 ) ; age 49.1+/-12.1 years ) underwent a 4-week comprehensive WM program . WM included a 7 MJ/day diet result ing in a stable weight during the first week and a 4.5 MJ/day diet with mean daily calcium intake 350 mg during the second to fourth week . Participants were divided into three age- and BMI -matched groups who received placebo or calcium ( 500 mg/day ) . Calcium was administered either as carbonate or calcium of dairy origin ( Lactoval ) . There was no significant difference in weight loss in response to WM between the placebo-treated and calcium-treated groups . However , addition of calcium to the diet result ed in a lower hunger score in the Eating Inventory as well as a decrease in plasma resistin levels . Body composition measured by bioimpedance demonstrated that added calcium leads to preservation of fat-free mass . Nevertheless , a greater loss of fat-free mass in the placebo group might be partly due to a greater loss of water
