Higher levels of vitamin D in the body are routinely linked to greater weight loss by research.
High vitamin D levels are associated with losing more belly fat and losing more weight overall.
People who are dieting have been shown to lose 20 pounds more when they have high vitamin D levels.
One study has shown that people drinking more milk, which contains vitamin D and calcium, can double weight loss.
Around half the world’s population is deficient in vitamin D.
Foods that are rich in vitamin D include oily fish and eggs, but most people get their vitamin D from the action of sunlight on the skin.
In the current study, 90 young women in the US had their vitamin D levels tested, along with their weight.
Low levels of vitamin D were linked to being heavier and shorter.
Dr Richard Kremer, the study’s first author, said:
“The high prevalence of vitamin D insufficiency in young people living in a sun-rich area was surprising.
We found young women with vitamin D insufficiency were significantly heavier, with a higher body mass index and increased abdominal fat, than young women with normal levels.”
One reason for the beneficial effect of vitamin D may be its link to the neurotransmitter serotonin.
Serotonin can affect everything from sleep to mood.
High levels of vitamin D may also suppress the storage of fat.
Dr. Vicente Gilsanz, study co-author, said:
“Clinicians need to identify vitamin D levels in younger adults who are at risk by using a simple and useful blood test.
Because lack of vitamin D can cause fat accumulation and increased risk for chronic disorders later in life, further investigation is needed to determine whether vitamin D supplements could have potential benefits in the healthy development of young people.”
