Purpose of review: The COVID-19 pandemic has challenged public health to a significant extent by markedly increasing morbidity and mortality. Evidence suggests that obesity and hypovitaminosis D constitute important risk factors for SARS-CoV-2 infection, severity of disease, and poor outcomes. Due to their high prevalence globally, obesity and hypovitaminosis D are considered pandemics. This review presents current epidemiologic and genetic data linking obesity, hypovitaminosis D, and COVID-19, highlighting the importance of the convergence of three pandemics and their impact on public health. We also briefly summarize potential mechanisms that could explain these links.

Recent findings: Epidemiologic data have shown that obesity is an independent risk factor for COVID-19, severe disease and death, and genetic evidence has suggested a causal association between obesity-related traits and COVID-19 susceptibility and severity. Additionally, obesity is independently associated with hypovitaminosis D, which is highly prevalent in subjects with obesity. Hypovitaminosis D is independently associated with a higher risk for COVID-19, severity, hospitalization, infectious complications, acute respiratory distress syndrome, and poor outcomes. However, genome-wide association studies have not revealed any causal association between vitamin D levels and the risk for COVID-19, while there is no robust evidence for a beneficial role of vitamin D supplementation in the prevention and treatment of COVID-19. In the context of the ongoing COVID-19 pandemic, the epidemiologic impact of obesity and hypovitaminosis D is emphasized. Efforts to increase public awareness and reinforce preventive and therapeutic measures against obesity and hypovitaminosis D are strongly required.

The study also points out that the effect of increasing BMI to the relative risk for severe and critical COVID-19 is higher in adults < 40 years and those of Black ethnicity.

In this study, the analysis of data from almost 0.5 million people from the UK Biobank showed that individuals with higher than normal BMI were at increased risk for severe COVID-19 in a dose-response way. For BMI above 25 kg/m2, the ORs ranged from 1.40 to 3.30, being higher for BMI > 40 kg/m2. Also, the study concluded that central obesity and genetic predisposition for obesity are associated with a higher risk for severe COVID-19.

Curr Obes Rep. 2021;10(2):162-180. https://doi.org/10.1007/s13679-021-00433-1. This review summarizes current evidence from meta-analyses regarding vitamin D status in obesity, weight loss and post-bariatric surgery, highlights important methodological limitations of relevant studies, and discusses potential pathophysiologic mechanisms and important controversies. The authors con­clude that obesity is associated with low vitamin D status, but weight loss has little effect on improving vitamin D lev­els. Moreover, vitamin D supplementation is not associated with weight loss, while it has shown contradicting results after bariatric surgery.

PLoS Med. 2013;10:e1001383. https://doi.org/10.1371/ journal.pmed. 1001383. This seminal study investigated the causality and direction of the association between BMI and vitamin D, by using a bi-directional Mendelian randomiza­tion analysis. In more than 42,000 participants from 21 adult cohorts, 12 BMI-related SNPs and 4 vitamin D-related SNPs were studied. The analysis showed that a higher BMI leads to lower vitamin D, while lower vitamin D has a rather small if any effect on increasing BMI.

This study used data from more than 350,000 UK Biobank partici­pants to investigate whether the addition of metabolic disorders and vitamin D insufficiency increased obesity associations with COVID-19 hospitalization, confirmed COVID-19, and severe COVID-19. The multivariate logistic regression analysis showed that obesity combined with metabolic disorders and hypovitaminosis D is associated with a significantly increased risk of COVID-19 severity, especially in adults 65 years and older.

  • Normal weight     Obese     (50 ng = 125 nanomole)


VitaminDWiki - Obesity is associated with low Vitamin D (and treated by D as well) – Aug 2019 contains

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
   * Start losing weight 2 months sooner if take a 50,000 IU daily for a week
3) More weight loss if also add Magnesium or cofactors
   30% Improved Vitamin D response with Magnesium - a Vitamin D Cofactor
   Note: Magnesium reduces weight loss by itself as well
   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: 0-30% improved Vitamin D response
   Obesity 1.5 X more likely if poor Vitamin D Receptor – meta-analysis Nov 2019
Update Dec 2019 - Dr. Greger plant-based eating (not diet) for both weight loss and health.
  His book does not mention Vitamin D nor Adenovirus
