Vitamin D
Obesity is associated with a number of metabolic disorders such as insulin resistance, hyperinsulinemia, cancer, abnormal fasting glycemia, diabetes mellitus, dyslipidemia, cardiovascular disease, respiratory dysfunction, skeletal changes, kidney, liver and nutritional dysfunction.
The concentration of vitamin D in obesity is reduced. Since vitamin D is fat-soluble, it is involved in the absorption of trace elements – calcium, magnesium and phosphates. Vitamin D deficiency in obesity is associated with an unbalanced diet and low outdoor physical activity. The direct correlation of the lack of vitamin D in the body with fat mass is explained by the storage of this vitamin in adipose tissue.
Vitamin D is believed to suppress the parathyroid hormone. The latter triggers the accumulation of fat in adipose tissue by increasing intracellular calcium. Other studies suggest that vitamin D deficiency contributes to insulin resistance. It is known that a diet rich in calcium and vitamin D products increases fat oxidation, stimulates the destruction of fat cells, and reduces lipid absorption due to the formation of insoluble calcium soap and fatty acids in the intestine.
Vitamin D in diet necessary. Plus vitamin A and E for the skin. And of the trace elements, iron is needed to increase muscle mass.
