Obese people may need more Vitamin D

People who are obese may not have enough Vitamin D in their system.

British researchers combined data from more than 20 studies and found for every 10% increase in BMI, Vitamin D levels went down 4%.

They say the vitamin is stored in fatty tissue, and if there's an excessive amount of fat, it could prevent the vitamin from circulating in the bloodstream.

Vitamin D deficiencies can cause bones to soften and weaken.

Vitamin D is made after exposure to the sun. Experts say simple activities like walking the dog or going for a stroll in the park could boost levels of the vitamin and help people lose weight.
