**5. Conclusions**

As long as vitamin D deficiency is prevalent in many parts of the world and the supplements are an affordable option, the deficiency of vitamin D may be a common and easily treatable risk factor for several health issues including obesity, but further studies are required to address different confounding factors and variabilities especially prospective studies to study the causal relationship between the deficiency of this vitamin and obesity as well as focus on the safety as well as the required dose regimen. Strong well-structured studies with limited confounding factors that will result in clear data interpretation will contribute to the future planning of health policies and guidelines used by healthcare professionals.
