4. Obesity
Obese individuals are at an increased risk for vitamin D deficiency. This may be partly due to the fact that fat cells can trap vitamin D and prevent it from circulating in the body. In addition, obese individuals tend to spend less time outdoors and thus have less exposure to sunlight, which is necessary for the body to produce vitamin D.
If you are obese, it is essential to talk to your doctor about your vitamin D deficiency risk and whether you need to take a supplement. Getting regular sun exposure and maintaining a healthy weight are both excellent ways to help prevent this condition.
