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

Obesity Gene (FTO) was not a problem for people born before WWII NYT Jan 2014

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

  • 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

PLOS ONE, Published: November 05, 2014DOI: 10.1371/journal.pone.0111265

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.

The higher the Vitamin D, the stronger the Hand Grip


BACKGROUND: It has been suggested that overweight and obese individuals have an increased risk to develop vitamin D deficiency, commonly associated with poor muscle performance. The relationship among fat mass, vitamin D status, and skeletal muscle is still debated.

AIMS: To evaluate the effects of the combination of hypovitaminosis D and overweight on muscle mass and strength, and physical performance in post-menopausal women.

In this cross-sectional study, we recruited post-menopausal women referring to a physiatric outpatient service for the management of osteoporosis over a 36-month period. We compared four groups:

  • (1) normal weight with hypovitaminosis D;
  • (2) overweight with normal serum 25(OH)D3;
  • (3) overweight with hypovitaminosis D; and
  • (4) normal weight with normal serum 25(OH)D3 (control group).

Outcome measures were: appendicular lean mass-to-BMI ratio; hand grip strength; and short physical performance battery.

We analysed 368 women (mean aged 67.2 ± 7.8 years): 95 normal weight with hypovitaminosis D, 90 overweight with normal levels of 25(OH)D3, 96 overweight with hypovitaminosis D, and 87 normal weight with normal levels of 25(OH)D3. Overweight women with hypovitaminosis D had a significant risk of reduced muscle mass (OR 5.70; p < 0.001), strength (OR 12.05; p < 0.001), and performance (OR 5.84; p < 0.001) compared to controls. Normal weight women with hypovitaminosis D had only a greater risk of an impairment of muscle strength (OR 7.30; p < 0.001) and performance (OR 3.16; p < 0.001).

According to our findings, both hypovitaminosis D and overweight should be investigated in post-menopausal women because of their negative effects on skeletal muscle mass and function.

This study demonstrated that hypovitaminosis D is associated to impaired muscle function and its combination with overweight might lead also to muscle wasting in a cohort of post-menopausal women.
