There are many studies. It was found that obesity and low vitamin D levels are related (Obesity is conversely related with serum Vitamin D), which is continually increasing. Both children and adults of every race.
The question that follows is
- Is vitamin D deficiency a cause or a result of obesity?
- What causes low vitamin D in obese people?
- Can vitamin D supplementation in obese people help them lose weight?]
Vitamin D It is a fat-soluble vitamin. which is distributed in various tissues throughout the body including fat tissue, muscle, liver, and in the bloodstream. Obese people often have lower levels of vitamin D than non-obese people, about 20% (Serum Vitamin D is about 20% lower in obese people than normal weight), even though obese people get vitamin D from food and sunlight The amount is not less than that of a non-obese person. But because obese people have more fat tissue. Vitamin D is thus distributed. Insulin-resistant adipose tissue can also produce enzymes that affect the vitamin D synthesis process. Therefore, it can be concluded that vitamin D is low. This is partly a result of obesity.
Vitamin D is known to reduce inflammation levels in adipose tissue. and is important for the function of insulin Both directly and indirectly But from the large collection of studies available so far, there are only 4-5 good quality studies. who concluded that vitamin D supplementation in obese people who are vitamin D deficient Helps in weight loss programs It has the effect of reducing fat mass, abdominal fat (visceral fat), reducing waist circumference, reducing triglycerides, increasing good fats, and reducing oral glucose tolerance, but it does not directly contribute to weight loss. and did not reduce inflammation as well
However, from the collection of large-scale research to date, It is still inconclusive whether vitamin D supplementation helps with weight loss.
Obese people with low vitamin D Often require higher doses of vitamin D supplementation than non-obese people. and vitamin D levels may increase. While losing weight Therefore, one must be careful of toxicity from too much vitamin D. Therefore, if you want to supplement with vitamin D, you should:Check vitamin D levels and consult a doctor to continue supplementing with appropriate doses of vitamin D.
