Probably only those getting vitamin D levels > 30 ng got a BMI reduction
- Waist size reduced 3 cm by Vitamin D in those with Metabolic Syndrome – Jan 2017
- Overweight and obese lost 12 lbs with vitamin D in 6 months– RCT May 2015
- Dieters lost 5 more pounds if achieved more than 32 ng of vitamin D – RCT March 2014
- 50,000 IU vitamin D weekly increased levels by 52 ng normally, but only 28 ng if obese – Oct 2013
- Obesity not reduced with 7,000 IU vitamin D daily – April 2013
Note: 60,000 IU/month in the study on the page = 2,000 IU daily, not nearly enough

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.

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

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
- Vitamin D status is a determinant of skeletal muscle mass in obesity according to body fat June 2015
Those with high BMI but with more skeletal muscle mass had higher levels of vitamin D

Seems that most problems are also associated with low vitamin D

"What is available out there for those of us who can’t take a vitamin ‘pill’ because it seems to get stuck in our pouch?"
"Since A, D & E are fat solubles and we are now malabsorbing fats ‘n oils to a degree, it would do us no good to take these in soft-gel (oil filled) forms. They need to be taken in DRY form."

Obesity is three times as deadly for men than women Telegraph July 2016
Compared to healthy size
- Obese people will die 3 years sooner
- Overweight people will die 1 year sooner
Death of men before age 70
20% if healthy weight
33% if moderately obese
80% of morbidly obese.

- Hertfordshire, which has population of more than 1.1. million.
- The time frame for improving health is set at nine months for the obese in particular; those with a body mass index over 40 must reduce the number by 15% over that time period, and those with a BMI over 30 are given a target of 10%.
- The target for smokers is eight weeks or more without a cigarette — with a breath test to prove it.

The Importance of Body Weight for the Dose Response Relationship of Oral Vitamin D Supplementation and Serum 25-Hydroxyvitamin D in Healthy Volunteers

We analyzed 22,214 recordings of vitamin D supplement use and serum 25(OH)D from 17,614 healthy adult volunteers participating in a preventive health program. This program encourages the use of vitamin D supplementation and monitors its use and serum 25(OH)D and serum calcium levels. Participants reported vitamin D supplementation ranging from 0 to 55,000 IU per day and had serum 25(OH)D levels ranging from 10.1 to 394 nmol/L. The dose response relationship between vitamin D supplementation and serum 25(OH)D followed an exponential curve.
Obese need more Vitamin D: Volume dilution, IU per pound, or BMI – RCT Dec 2012 has the following chart

Inverse relationship between metabolic syndrome (MetS) and 25-hydroxyvitamin D (25(OH) D) levels is controversial. Hypovitaminosis-D has long been suspected as a risk factor for glucose intolerance.
AIM:A randomized double blind placebo controlled study to evaluate effects of vitamin D supplementation on insulin resistance in subjects with hypovitaminosis-D and MetS.
MATERIALS AND METHODS:
Subjects were randomized to receive either oral 25(OH) D3 supplement (60000 (IU) per week for 8 weeks followed by 60,000 IU monthly for 4 months) or a placebo for six months. The parameters measured were blood pressure, vitamin D, fasting blood sugar (FBS), insulin, homeostasis model assessment (HOMA), quantitative insulin sensitivity check index (QUICKI), body mass index (BMI), and waist circumference (WC).
There were no significant changes in parameters of vitamin-D group compared to placebo group except serum vitamin-D was significantly increased in vitamin-D group (p < 0.0001). In vitamin-D group, mean WC at baseline was 95.9 ± 6.66, which significantly changed to 94.6 ± 7.47 (p = 0.001).
Mean BMI at baseline was 29.1 ± 4.06 which significantly changed to 28.5 ± 4.16 (p = 0.001). The mean vitamin-D concentration at baseline was 15.4 ± 9.03 which significantly (p < .0001) increased to 26.1 ± 11.8. In placebo group mean insulin levels was 10.7 ± 4.81IU / L which increased significantly (p = 0.03) to 15.4 ± 14.0. Mean QUICKI at baseline was 0.34 ± 0.03 which decreased significantly (p = 0.02) to 0.32 ± 0.03.
In this study the relationship between vitamin D supplementation and MetS or IR was not established. Whether achieving vitamin D sufficiency in large population-based trials with a longer duration would produce more favorable results needs to be assessed.
