Comment by the founder of VitaminDWiki

  • Probably would have had much more weith loss if had repleted Vitamin D BEFORE the diet and exercise portion of the program.
  • The Vitamin D would have been virtually useless in the first month or two of this 3-month program
  • Repletion can take 8-12 weeks if given bi-weekly (1,200,000 = 12 week X 100,000 IU)
  • Repletion <2 weeks if given all within a single week (e.g. 170,000 daily)

Overview Obesity and Vitamin D contains the following summary

IN BRIEF This study explored the impact of correcting vitamin D deficiency on blood pressure, metabolic status, and weight loss in patients with fatigue and obesity refractory to conventional interventions such as diet, exercise, behavioral modification, and pharmacotherapy. Correction of vitamin D deficiency in such patients was found to be significantly associated with weight reduction and improved insulin sensitivity.
