Taking vitamin D supplements can significantly increase weight loss, according to a recent study.
Researchers found that in people who took vitamin D supplements, weight loss was four times the weight loss without taking vitamin.
Vitamin D also doubled the number of centimeters taken from their waist.
Low levels of vitamin D have been repeatedly associated with overweight and obesity.
Nearly 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 divided 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 did not take any.
After six months, the results showed that both groups of vitamin D lost more weight than those who did not take this vitamin.
Those who took 100,000 or about 3,000 IU per day had a weight loss of 5 kg.
People taking 25,000 IU, or about 800 IU per day, lost almost 4 kg.
In comparison, those on a calorie-restricted diet lost only 1 kg in weight in six months.
The authors of the study write:
“Current evidence suggests that in obese and overweight people with vitamin D deficiency, vitamin D supplementation can help reduce weight and increase the benefits of a low-calorie diet.”
Measurements of the waist during the diet also showed that vitamin D had a great effect.
Those who took 100,000 IU lost an average of 5 cm from their waist, compared with just over 2 cm in the other in the control group.
“All obese people should check their vitamin D levels for deficiency and, if there is one, start taking supplements.”
