Overweight and obese lost 12 lbs with vitamin D in 6 months– RCT May 2015

Will try to get more information
Can speculate even greater weight loss in a RCT which:

1. Start with a loading dose - say 50,000 IU daily for the first week
2. Used a higher dose of vitamin D - perhaps 50,000 IU weekly (= 200,000 IU monthly)
3. Added 100 mg of Magnesium daily- in the form of Magnesium Chloride
   Magnesium (in the water) can increase the response to a dose of vitamin D
   Perhaps the adults in this study drank hard water (Magnesium)
      That is, perhaps there was something in the water

• 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.
