Overview Obesity and Vitamin D

• FACT: People who are obese have less vitamin D in their blood
• FACT: Obese need a higher dose of vitamin D to get to the same level of vit D
• FACT: When obese people lose weight the vitamin D level in their blood increases
• FACT: Adding Calcium, perhaps in the form of fortified milk, often reduces weight
• FACT: 168 trials for vitamin D intervention of obesity as of Dec 2021
• FACT: Less weight gain by senior women with > 30 ng of vitamin D
• FACT: Dieters lost additional 5 lbs if vitamin D supplementation got them above 32 ng - RCT
• FACT: Obese lost 3X more weight by adding $10 of Vitamin D
• FACT: Those with darker skins were more likely to be obese Sept 2014
• OBSERVATION: Low Vitamin D while pregnancy ==> more obese child and adult
• OBSERVATION: Many mammals had evolved to add fat and vitamin D in the autumn
  • and lose both in the Spring - unfortunately humans have forgotten to lose the fat in the Spring
• SPECULATION: Low vitamin D might be one of the causes of obesity – several studies
• SUGGESTION: Probably need more than 4,000 IU to lose weight if very low on vitamin D due to
    risk factors such as overweight, age, dark skin, live far from equator,shut-in, etc.
• Obesity category has 428 items See also: Weight loss and Vitamin D - many studies   Child Obesity and Vitamin D - many studies

Obese need more Vitamin D

Vitamin D results in fastest Obese weight loss, and about 3X more pounds -2019

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

Strong indications in Missing Microbes that early antibiotics increases the risk of obesity

1. Farmers have been giving low-level anitbiotics to animals since they learned long ago that it would increase by 10% the animal weight without increased cost of feed
2. Mice given low-level antibiotics for first 4 weeks of life become heavier later in life
3. Children who are given antibiotics in first 6 months of life are 5X more likely to become obese (study in England of 14,000 births)
4. US States which get the most antibiotics are those states with the most obesity (CDC)
5. Obese US adults have 1/2 of the gut biotic diversity of non-obese adults (400,000 vs 800,000)
6. Germ-Free mice became obese when given fecal transplants from mice who had antibiotics and became obese
   This is a strong indication that the cause of the obesity was the gut microbiome

BMI increase 1980-2008 (nothing about vitamin D) - 2015

Washington Post interactive graphic Aug 2015

Black line = US BMI increase
From 1980 to 2008, the average BMI for men rose in all but eight countries; the average for women rose in all but 19. Globally, nearly 10 percent of men and nearly 14 percent of women are obese, meaning their BMI is 30 or more. In some countries, particularly in the Pacific Islands, obese is average. Countries with a high average BMI tend to have high rates of diabetes, and vice versa.

GLP-1 weight-loss drugs (Wegovy etc): huge market, many competitors coming, many side effects, possible other uses - April 2024

Weight-loss drugs could end the obesity epidemic. But they won’t stop there Economist April 2024

• " Sales for weight-loss drugs are estimated to hit $80bn per year by the end of the decade. "
• "Almost 100 new drugs are in the development pipeline. Most of them hope to outperform Wegovy and Mounjaro by being easier to take, causing fewer side-effects or delivering more effective weight loss."
• Reduces risk of heat attack by 20%, might help with Alzheimer's, addictions
• "Another drawback of GLP-1-based medicines is that patients do not just shed fat, they also lose lean muscle mass. "

BMI - what is wrong with it NY Times - April 2014

Invented in early 1800's
Never meant to be a measure for individuals
Currently 18.5 = underweight; 18.5 and 24.9 = normal; 25 to 29.9 = overweight; >30 = obese.
Grade 1 =30 - 34.9; Grade 2= 35 - 39.9; Grade 3 > 40
At best, though, B.M.I. is a crude measure that actually misses more than half of people with excess body fat,
It measures total body weight, not just fat. When Arnold Schwarzenegger was Mr. Universe, his B.M.I. was well in the obese range

First discovered in 2007. Confirmed many times since then.
Each copy of the FTO variant adds 3.5 pounds. 2 copies ==> 7.0 lbs
So, they think that environment (exercise) turns on/off genetics
Addional possibilites include:

• decreased Vitamin D,
• decreased Magnesium,
• Increased antibiotics - which started just after WWII
