Obesity 1.5 X more likely if poor Vitamin D Receptor – meta-analysis Nov 2019

Vitamin D Receptor Polymorphisms Associated with Susceptibility to Obesity: A Meta-Analysis.

Med Sci Monit. 2019 Nov 4;25:8297-8305. doi: 10.12659/MSM.915678.

VitaminDWiki

Items in both categories Obesity and Vitamin D Receptor are listed here:


The risk of 44 diseases at least double with poor Vitamin D Receptor as of Oct 2019
Vitamin D Receptor Activation can be increased by any of:
Resveratrol, Omega-3, Magnesium, Zinc, non-daily Vitamin D dosing, etc
   Note: The founder of VitaminDWiki uses 10 of the 12 known VDR activators


Overview Obesity and Vitamin D contains the following summary


Obesity is associated with low Vitamin D (and treated by D as well) – Aug 2019 has the following

Fast weight loss by Obese: Summary of the data as of Sept 2019
1) 50,000 IU Vitamin D weekly for at least 6 months
   If gut problems, should use a gut-friendly form of vitamin D
2) Add calorie restriction diet and light exercise after ~2 months*
   * Vitamin D levels must be above 30ng/ml to help with weight loss
   * Can start losing weight 2 months sooner if take a 50,000 IU daily for a week (400,000 IU)
3) More weight loss if also add Magnesium or cofactors
Magnesium: 30% Improved Vitamin D response with Magnesium - a Vitamin D Cofactor
   Note: Magnesium reduces weight loss by itself as well
  Omega-3: 20% improved vitamin D response if also add Omega-3 a Vitamin D Cofactor
  Note: Omega-3 reduces weight loss by itself as well
4) More weight loss if also improve activation of Vitamin D Receptor
   Vitamin D Receptor activator provides 0-30% improved Vitamin D response))

BACKGROUND Obesity has become a global public health problem. Obesity increases the risk of several lethal diseases. This study aimed to assess whether the obesity susceptibility was associated with genetic variation in vitamin D receptor (VDR) gene by conducting a meta-analysis.

MATERIAL AND METHODS PubMed, EMBASE and Cochrane Library databases were screened for all relevant articles published up to October 2018. The pooled odds ratios (OR) were calculated using STATA 13.0 software for 4 polymorphisms in the VDR gene (ApaI, BsmI, FokI and TaqI).

RESULTS Seven case-control studies, including 1188 obese patients and 1657 healthy controls, were recruited. The pooled findings showed that there were no associations between obesity risk and the VDR polymorphisms in ApaI, BsmI and TaqI loci overall. However, VDR TaqI polymorphism was associated with the risk of obesity in Asian under homozygous [TT versus tt: odds ratio (OR)=0.26, 95% confidence interval (CI)=0.14-0.49; P<0.001], heterozygous (Tt versus tt: OR=0.34, 95% CI=0.18-0.64; P=0.001), and dominant (TT+Tt versus tt: OR=0.30, 95% CI=0.17-0.52; P<0.001) models; FokI variant was related with increased risk of obesity only under dominant model (FF+Ff versus ff: OR=1.54, 95% CI=1.15-2.06; P=0.004).

CONCLUSIONS Our meta-analysis results suggest that the T allele of TaqI may have a protective effect, while the F allele of FokI is proposed as a risk factor related to obesity.
