Weight management for improved vitamin D levels, diabetes diet and metabolic syndrome management.
There have been studies done on the improvement of nutritional deficiencies following gastric bypass surgery, and it is known that vitamin D levels are depressed in obese individuals. The heavier the individual, the lower the vitamin D levels, and the release of vitamin D stored in body fat has been suggested as a cause for this improvement in vitamin D levels associated with weight loss. In addition, the improvement in vitamin D levels accompanying weight loss has been associated with decreased insulin resistance.
Recent research on older women who are overweight or obese shows that if they lose more than 15% of their body weight they could significantly increase their levels of vitamin D. The study, published in the May 25 online issue of the American Journal of Clinical Nutrition, assigned 439 overweight or obese post-menopausal women to one of four regimens for 12 months: 1) exercise only 2) diet only 3) exercise plus diet and 4) no intervention. Although women who lost up to 10% of their body weight (10 to 20 pounds) through diet and exercise saw modest increases in vitamin D, those levels were roughly three times higher in women who dropped more than 15% of their body weight, regardless of what they ate.
It sounds like somewhat of a chicken-and-egg phenomenon to me. Is the low vitamin D a factor in the increased BMI and/or is the increased BMI causing low vitamin D levels? Probably an interplay between a number of factors leading to a downward health spiral. The solution, lose weight and supplement with vitamin D. This is especially important if you have diabetes or prediabetes metabolic syndrome. The diabetes diet and diabetes exercise information on this site is a good place to start.
