Half of Americans have some interest in Weight Loss drugs- Aug 2023

MD Edge

  • "A recent survey of more than 1,000 U.S. adults showed that
    • 18% were “somewhat interested” in taking a “safe, effective” weight loss drug,
    • 27% were “very interested,” and
    • 4% said they were already using such an agent,
      • together constituting 49% of the surveyed adults."

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

Fast weight loss by Obese Adults: 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


Does obesity vary with lattitude? asked Perplexity AI Aug 2024

Based on the provided search results, there does appear to be a relationship between obesity prevalence and latitude.
The key findings are:

  1. An analysis of gut microbes from over 1,000 people worldwide found that people living in northern latitudes had a greater proportion of obesity-related bacteria in their guts compared to those living farther south. Researchers hypothesize this could be an evolutionary adaptation, with obesity-linked bacteria being better at extracting energy from food which may have aided survival in colder northern climates in the past.
  2. A study across U.S. counties found that a 1-standard-deviation (11°F) decrease in January temperature, or a 1-standard-deviation (5°F) increase in July temperature, predicted a 0.7% increase in county obesity prevalence, after controlling for confounding factors. This suggests obesity prevalence increases in areas with colder winters and hotter summers.
    (Note: Hot summer ==> Avoid the sun with indoor air conditioning)
  3. However, a study in Peru found an inverse association between altitude and obesity - Peruvian individuals living at higher altitudes had a lower prevalence of obesity compared to those living closer to sea level, even after adjusting for multiple covariates. The biological mechanisms are not well understood but could relate to differences in temperature, diet, or physical activity levels at high altitudes.
    (Note higher altitude ==> more UVB ==> more vitamin D from the sun)
  4. Globally, the prevalence of obesity has increased across countries at all levels of development in recent decades, indicating the obesity problem is not simply a function of latitude or income level. However, the global distribution of obesity does show geographical variation.

In summary, while the relationship is complex and influenced by many factors, the available evidence points to a general trend of higher obesity prevalence in northern latitudes with colder climates compared to areas closer to the equator. More research is needed to fully understand the geographical variation in obesity and the underlying mechanisms.
