Weight Loss Induces Changes in Vitamin D Status in Women With Obesity But Not in Men: A Randomized Clinical Trial.

What Was Tested

This randomized controlled trial looks at Vitamin D, K2, Magnesium and Zinc in the context of fat loss, obesity & body recomposition.

The aim of this study was to investigate the effects of weight loss on vitamin D status in individuals with obesity, and secondarily, whether vitamin D metabolism differs between women and men.

Who Took Part

The abstract describes 195 individuals taking part.

The age groups tagged for this paper are adults and middle-aged adults, both men and women.

How the Study Was Run

In design terms this was a randomized and placebo-controlled study.

The individuals were allocated by chance, so the Vitamin D, K2, Magnesium and Zinc group and the comparison group should start out alike.

Some individuals received a placebo instead of Vitamin D, K2, Magnesium and Zinc, giving a reference point.

What Was Measured

The subject headings attached to it are Weight Loss, Obesity, Vitamin D, Caloric Restriction, Liraglutide, Sex Factors and Vitamin D Deficiency.

Author keywords: GLP-1 receptor agonist, glucagon-like peptide-1 and sex differences.
