Researchers found that when somebody is both obese and has low Vitamin D levels, their risk of insulin resistance is much greater than if they have either factor alone.
Together with the suggested increases in Vitamin D requirements in obese individuals, our study highlights the importance of monitoring and treating Vitamin D deficiency as a means of alleviating the adverse influences of excess adiposity on health.Our findings suggest that population level interventions to reduce obesity would be expected to lead to a reduction in the prevalence of Vitamin D deficiency.
