I have often thought that obesity may be an indication that the body is trying to get a nutrient – perhaps the nutrient is vitamin D. Henry Lahore, founder of VitaminDWiki

- Virtually all Bariatric Surgery patients vitamin D deficient – should we routinely supplement – Jan 2011
- Prior to Bariatric Surgery 96 percent were vitamin D deficient – July 2014
- Vitamin D probably important for Bariatric Surgery – April 2018
- Overview Deficiency of vitamin D has a chart - a portion of which shows the problems AFTER the surgery
Overview Obesity and Vitamin D contains the following summary
- 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: 153 trials for vitamin D intervention of obesity as of Sept 2020
- 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: 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
- 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
- Normal weight Obese (50 ng = 125 nanomole)
- Vitamin D, impulsivity and eating behaviors in the obese: Is there a connection?

Obesity is recognized as a major health problem. Vitamin D is involved in maintaining energy metabolism by regulation of glucose transporters, uncoupling proteins, and normal brain function. We aimed to explore a relationship between impulsivity, eating behaviors, and 25-hydroxyvitamin D concentration in a sample of 322 bariatric surgery candidates.
Participants completed a questionnaire on their health, eating habits and The Eating Disorders Examination-Questionnaire (EDE-Q). Impulsivity was evaluated with the Barratt Impulsiveness Scale (BIS-11). Blood samples were obtained to measure levels of 25(OH)D, lipids (cholesterol, triglyceride, HDL-cholesterol, LDL-cholesterol), and glucose.
Overall scores on the BIS-11, along with scores on the Attentional Subscale of the BIS were significantly higher in participants with higher frequency of snack food consumption. Scores on the Attentional Subscale of the BIS were higher in participants who self-reported eating in response to emotions. Participants who reported eating at night or declared intense emotions associated with a desire-to-eat had the highest global, attentional, and non-planning impulsivity levels. Scores on the Non-planning Subscale of the BIS-11 were elevated in participants with 25-hydroxyvitamin D concentrations lower than 10ng/ml.
The results suggest that the higher level of impulsivity among the patients with obesity is associated with eating habits, and support the hypothesis that vitamin D deficiency may contribute to impulsiveness.Impulsive or binge eating may be associated with low vitamin D – Nov 2018
