Higher vitamin D levels in the body are linked to greater weight loss, research finds.
People on a diet increased their weight loss by 20 pounds (9 kg) or more when they had higher vitamin D levels.
They also lost more abdominal or ‘belly’ fat.
Dr Shalamar Sibley, study co-author, said:
“Our results suggest the possibility that the addition of vitamin D to a reduced-calorie diet will lead to better weight loss.”
For the study, 38 overweight people followed a standard calorie restricted diet.
For 11 weeks they ate 750 fewer calories per day.
The results showed that the higher their vitamin D levels before they started dieting, the more weight they lost.
Those with higher levels of vitamin D in their body also lost more belly fat.
Dr Sibley said:
“Vitamin D deficiency is associated with obesity, but it is not clear if inadequate vitamin D causes obesity or the other way around.
Our findings need to be followed up by the right kind of controlled clinical trial to determine if there is a role for vitamin D supplementation in helping people lose weight when they attempt to cut back on what they eat.”
