The addition of vitamin D to a reduced-calorie diet will lead to better weight loss.
Vitamin D levels in the body at the start of a low-calorie diet predict weight loss success, a new study found. The results, which suggest a possible role for vitamin D in weight loss, were presented at The Endocrine Society’s 91st Annual Meeting in Washington, D.C.
“Vitamin D deficiency is associated with obesity, but it is not clear if inadequate vitamin D causes obesity or the other way around,” said the study’s lead author, Shalamar Sibley, MD, MPH, an assistant professor of medicine at the University of Minnesota.
In this study, the authors attempted to determine whether baseline vitamin D levels before calorie restriction affect subsequent weight loss. At the start of the study the enrolled overweight men and women had vitamin D levels that many experts would consider to be in the insufficient range, according to Sibley.
However, the authors found that baseline, or pre-diet, vitamin D levels predicted weight loss in a linear relationship. For every increase of 1 ng/mL in level of 25-hydroxycholecalciferol—the precursor form of vitamin D and a commonly used indicator of vitamin D status—subjects ended up losing almost a half pound (0.196 kg) more on their calorie-restricted diet. For each 1-ng/mL increase in the active or “hormonal” form of vitamin D (1,25-dihydroxycholecalciferol), subjects lost nearly one-quarter pound (0.107 kg) more.
Additionally, higher baseline vitamin D levels (both the precursor and active forms) predicted greater loss of abdominal fat.
“Our results suggest the possibility that the addition of vitamin D to a reduced-calorie diet will lead to better weight loss,” Sibley said.
A daily dose of Vitamin D can cut cancer risk by 25%. It protects against heart disease, high blood pressure, aging, diabetes, inflammatory diseases, arthritis and multiple sclerosis, among others, as well as treating some existing conditions.
Only a few foods contain vitamin D naturally, such as cord liver oil and fatty fish, which includes Salmon and Sardines. Other sources are dietary supplements and vitamin-D-fortified foods, including milk, cereals and orange juice. Three 8-ounce glasses of lowfat or fat free milk provide 75 percent of the daily value for vitamin D.
Vitamin D is one vitamin that is as good in supplement form as from natural sources.
Healthy adults can safely take 2000 to 3000 units a day. Your Doctor can monitor as to what is the right dosage for you. American Academy of Pediatrics recommends 400 IU daily for children and teens.
