Obesity could lead to vitamin D deficiency

Obesity has the potential to lower vitamin D levels in the body, according to a study published in PLOS Medicine.

A report from bbc.co.uk confirmed that the study analysed genetic data from 21 studies that involved 42,000 people, in order to find any correlation between body mass and vitamin D levels.

The study found for every ten per cent rise in body mass index (BMI), there was a four per cent drop of available vitamin D in the body, dailypaul.com reports. Furthermore, as vitamin D is stored in fatty tissue, the study's author believe the 'larger storage capacity' in obese people may prevent it from circulating in the bloodstream.

Low vitamin D levels can cause the weakening of bones, leading to rickets in children and osteomalacia in adults. Consequently, it could drive obese children and adults to lose weight. Counselling courses, for example, can find out any underlying issues or root causes for weight gain, which can make the process of keeping healthier easier.

Professor David Haslam, from the National Obesity Forum, commented on the figures: "Food intake and genetics all play a part in obesity - but this research is a reminder that physical activity, like walking the dog or going for a run out in the sunshine, shouldn't be forgotten and can help correct both weight and lack of vitamin D."
