What Is the Association Between Vitamin D and Obesity

What Is the Association between Vitamin D and Obesity?

• Vitamin D deficiency is common in obese individuals. Lipid- soluble vitamin D tends to be stored in fat tissues. Fat tissues may store a large amount of vitamin D, while the rest of the body is void of vitamin D. Weight loss can release vitamin D from fat tissues in obese people.

• Vitamin D deficiency triggers the parathyroid gland to produce parathyroid hormone, which causes the body to store fat in fat tissues. Vitamin D deficiency also stimulates appetite and leads to binge eating and obesity.

Meta-analysis

• Vitamin D. A meta-analysis of 15 research articles studied the association between vitamin D and obesity in 3,867 obese people and 9,342 normal-weight individuals. Analysis confirmed that the majority of obese people were vitamin D deficient. Moreover, people who were vitamin D deficient were more likely to be obese compared to normal-weight individuals.

Recommendation

• Prevention. For people at risk of obesity, take daily 800 IU vitamin D3 (11) and 50 mg chromium (25).

• Treatment. For obese people, take daily 2,000 IU vitamin D3 (11) and 200 mg chromium (25).
