I've previously covered a couple studies linking vitamin D to body fat and weight (following the links below). Previously, Here is the latest on this topic, and it shows that vitamin D levels influence the incidence of obesity (not a consequence of obesity).
In this new study, researchers collected data from 1226 people at three different visits over a ten-year period. Results showed that rates of obesity increased over the study period, with a prevalence of 28.1, 36.2 and 39.5%, for the 1st, 2nd, and 3rd visits, respectively.
Although no link between levels of vitamin D and obesity were observed at the start of the study, the data indicated that non-obese people with vitamin D deficiency at the time of the second visit had a significantly increased risk of developing obesity in the next four years.
However, the mechanisms involved in the action of vitamin D on the activity and differentiation of adipose tissue are still largely unknown. "One of these pathways could be because 1,25-hydroxyvitamin D may block the differentiation of adipose tissue, suppressing the activity of lipoprotein lipase, aP2, PPAR-γ, C/EBP-α and SREBP-1, although other mechanism can be involved," wrote the researchers.
Regardless, probably a good idea to make sure you get plenty of vitamin D.
