Taking vitamin D supplements can significantly increase weight loss, according to a recent study.
People who took vitamin D supplements had over four times the weight loss as those that did not, researchers found.
Vitamin D also doubled the number of inches taken off their waistlines.
Low levels of vitamin D is repeatedly linked to being overweight and obese.
Almost 40 percent of obese people are deficient in vitamin D.
The study included 400 obese and overweight people with vitamin D deficiency.
They were put on a low-calorie diet and split into three groups.
One group took 25,000 IU of vitamin D per month, the second took 100,000 IU of vitamin D per month and the control group took none.
Six months later the results showed that both vitamin D groups had lost more weight than those who were not taking the vitamin.
Those taking 100,000, or around 3,000 IU per day, had 12 pounds of weight loss.
People taking 25,000 IU, or around 800 IU per day, lost 8 pounds.
In comparison, those only following the calorie restricted diet had just 2.6 pounds of weight loss over the six months.
The study’s authors write:
“The present data indicate that in obese and overweight people with vitamin D deficiency, vitamin D supplementation aids weight loss and enhances the beneficial effects of a reduced-calorie diet.”
Measurements of dieters’ waistlines also revealed vitamin D had had an effect.
Those taking 100,000 IU lost an average of two inches from their waistline compared to just over 1 inch in the control group.
The researchers conclude:
“All people affected by obesity should have their levels of vitamin D tested to see if they are deficient, and if so, begin taking supplements.”
