National Health and Nutrition Examination Survey (NHANES) 2017-2018
Adults
Nearly 1 in 3 (30.7%) are overweight
More than 2 in 5 (42.4%) have obesity or severe obesity: BMI >30) both = 73%
About 1 in 11 (9.2%) have only severe obesity (BMI >40)
Children and adolescents (age 2-19)
About 1 in 6 (16.1%) are overweight
Almost 1 in 5 (19.3%) have obesity or severe obesity
About 1 in 16 (6.1%) have only severe obesity
Note: Unable to quickly find US data on increased overweight or obesity following COVID era
Note: Mexican adults and children are even more overweight or obese than US

- "As of 2012, diabetes - associated with obesity - was the largest single killer of Mexicans.[15]
As of 2016, it was responsible for over 100,000 premature deaths in the country.[16]"
VitaminDWiki – Overview Obesity and Vitamin D contains:
- 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 442 items

Obese need more Vitamin D
- Normal weight Obese (50 ng = 125 nanomole)

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