Abstract Background Obesity is a worldwide problem and is a major risk factor for chronic diseases. The relation between obesity and vitamin D is not completely understood. Obesity is associated with vitamin D insufficiency. Some studies claim that vitamin D may reduce lipogenesis and others claim that vitamin D can promote adipogenesis. Aim of the study This study was planned to evaluate the effect of alteration in vitamin D level on body weight and adipose tissue metabolism in an obese rat model. Methods 32 Female Albino-rats were randomly allocated into: control group (C, n = 8), fed on control diet containing 1000 IU vitamin D/kg diet, and a high caloric diet group (HCD, n = 32). The HCD group was further subdivided into 3 groups according to the vitamin D dose into: standard vitamin D dose group (HCD+SVD) containing 1000 IU vitamin D/kg diet, low vitamin D dose group (HCD+LVD) containing 25 IU vitamin D/kg diet and high vitamin D dose group (HCD+HVD) containing 5169 IU vitamin D/kg diet. Body mass index, serum vitamin D, glucose, lipid profile, TNF-α and adipose tissue UCP-1 were measured. Different fat depots were weighed and histopathologically assessed. Results HCD+HVD group showed a significant increase in the final body mass index and in the different fat depot weights compared to all groups. Compared to the HCD+SVD group, the HCD+HVD group showed significantly lower serum total cholesterol and LDL-c levels, while it showed a non-significant change in serum glucose, TNF-α and visceral adipose tissue UCP-1. A significant negative correlation was found between serum 25(OH)D and visceral adipose tissue UCP-1. HCD+LVD showed the highest visceral adipose tissue UCP-1 compared to all groups. Conclusion Vitamin D promoted adiposity and decreased visceral adipose tissue UCP-1 but improved the associated derangements in lipid profile.

In obesity, there is an accumulation of adipocytes which produces adipokine that are pro-inflammatory substance, such as leptin and MCP-1 and anti-inflammatory substance, such as adiponectin, while the bioavailability of vitamin D is decreased. This research aimed to study the effect of vitamin D administration on leptin, MCP-1, and adiponectin levels in adipose tissue rats with obesity. Vitamin D was administered to the obese model of 6-9 months old female Wistar rats. This experiment was a randomized control group design with a post-test group design only. Twenty-seven (27) female obese Wistar rats were included in this study. The animals were divided randomly into 3 groups: 9 rats were given 2400 IU vitamin D (group A), 9 rats were given 800 IU vitamin D (group B) and 9 rats were given a placebo as control (group C). The administration of Vitamin D was given once daily for 8 weeks. The visceral adipose tissue was taken to measure the level of leptin, adiponectin and mRNA MCP-1. Data among groups was analyzed by using one-way ANOVA and followed by LSD test, at a significance level of p <0.05. The lowest level of leptin (1059.15+135.20 pg/ml) and mRNA MCP-1 (2.36 + 0.75 fg/ml) and the highest adiponectin level (3.43 + 0.47 ng/ml) were found in group A. In conclusion, oral administration of vitamin D (2400 IU) decreased pro-inflammatory substances, such as leptin and mRNA MCP-1 and increased anti-inflammatory substances, such as adiponectin, in visceral adipose tissue of obese female Wistar rats.
