- Weight loss and Vitamin D, Calcium, and Magnesium
- Dieters lost 5 more pounds if achieved more than 32 ng of vitamin D – RCT March 2014
- Overweight and obese lost 12 lbs with vitamin D in 6 months– RCT May 2015
- Huge increases in Omega-6 to Omega-3 ratio increase risk of obesity, etc. – March 2016
- Obese women deficient in both Vitamin D and Vitamin B12 – March 2018
- Vitamin D stored in fatty tissue may have half life of 12 months (vs 2 months otherwise) – July 2017
12 month storage was great when people added weight in the Fall and lost weight before Spring
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: 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

Obese need more Vitamin D
