- Some of those who were deficient took 2,000 or 4,000 IU of vitamin D daily for 3 months
- The founder of Vitamin D Life believes that they would have had far more weight loss by
1) Starting with a loading dose
since the vitamin D level would not otherwise have gotten into a useful range for months
2)Taking vitamin D weekly or bi-weekly instead of daily
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

Fast weight loss by Obese: Summary of the data as of Sept 2019
1) 50,000 IU Vitamin D weekly for at least 6 months
If gut problems, should use a gut-friendly form of vitamin D
2) Add calorie restriction diet and light exercise after ~2 months*
* Vitamin D levels must be above 30ng/ml to help with weight loss
* Can start losing weight 2 months sooner if take a 50,000 IU daily for a week (400,000 IU)
3) More weight loss if also add Magnesium or cofactors
Magnesium: 30% Improved Vitamin D response with Magnesium - a Vitamin D Cofactor
Note: Magnesium reduces weight loss by itself as well
Omega-3: 20% improved vitamin D response if also add Omega-3 a Vitamin D Cofactor
Note: Omega-3 reduces weight loss by itself as well
4) More weight loss if also improve activation of Vitamin D Receptor
Vitamin D Receptor activator provides 0-30% improved Vitamin D response

Update Dec 2019 - Dr. Greger plant-based eating (not diet) for both weight loss and health.

Note: lots of weight loss by those who were not deficient
CONTEXT:
Obesity and low vitamin D status are linked. It is not clear that weight loss through lifestyle intervention is influenced by vitamin D status.OBJECTIVE:
The aim of this study was to investigate the effect of baseline vitamin D status and vitamin D supplementation on weight loss and associated parameters for participants on a weight loss program in a primary care setting.DESIGN:
A retrospective analysis of clinical records of patients who underwent an individually tailored weight loss program at a single dietetic clinic in Sydney, Australia.SETTING: Primary care centers.
PATIENTS: 205 overweight and obese men and women aged from 18 to 50 years.
INTERVENTIONS:
Patients were referred to a dietetic clinic for a weight loss program. Patients with low serum 25-hydroxyvitamin D (25(OH)D) concentrations at baseline were advised to increase sun exposure and take multivitamins supplemented with 2000 IU or 4000 IU per day of vitamin D3, according to the preference of their primary care physician.MAIN OUTCOME MEASURES:
Clinical parameters of weight, height, waist circumference, and serum 25(OH)D, as well as blood pressure and fasting lipid profile were collected from both baseline and three-month follow-up consultations.RESULTS:
Subjects with sufficient baseline 25(OH)D levels (≥50 nmol/L) experienced significantly greater weight loss (-7.7 ± 5.9 kg vs. -4.2 ± 3.3 kg) and reductions in BMI (-2.6 ± 1.8 kg/m2 vs. -1.5 ± 1.1 kg/m2) and waist circumference (-5.2 ± 3.5 cm vs. -3.1 ± 3.1 cm) as compared with those who were vitamin D insufficient at baseline (p < 0.001 for all). Vitamin D insufficient patients who were supplemented with daily 2000 IU or 4000 IU vitamin D experienced significantly greater decreases in weight (-5.3 ± 3.6 kg vs. -2.3 ± 1.6 kg), BMI (-1.9 ± 1.2 kg/m2 vs. -0.8 ± 0.6 kg/m2) and waist circumference (-4.2 ± 3.4 cm vs. -1.2 ± 1.3 cm) as compared with those not supplemented (p < 0.001 for all). We also observed a greater decrease in low-density lipoprotein (LDL) cholesterol (-0.4 ± 0.5 mmol/L vs. -0.2 ± 0.5 mmol/L) in subjects insufficient at baseline and supplemented as compared with those insufficient at baseline and not supplemented (p < 0.01).CONCLUSION:
In a weight loss setting in a dietetic clinic, adequate vitamin D status at baseline, or achieved at three months through supplementation, was associated with significantly greater improvement of anthropometric measures. The study has implications for the management of vitamin D status in obese or overweight patients undergoing weight loss programs.2.3 X more weight loss in those who had low vitamin D levels and took some – Dec 20191240 visitors, last modified 20 Dec, 2019, This page is in the following categories (# of items in each category)Obesity351 Intervention 638 Top news 814 Attached files
