The amount of vitamin D needed is a function of weight
Obese (adults, youths. children) need 3X more Vitamin D
Non-daily is better than daily,
Vitamin D turbo-charges many weight-loss regimes (fewer calories, more exercise, and perhaps fasting)
Takes ~3 months for Vitamin D levels to be beneficial if not start with a loading dose
Magnesium and Omega-3 help a lot

VitaminDWiki - Overview Obesity and Vitamin D contains
- 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

VitaminDWiki - Obesity is associated with low Vitamin D (and treated by D as well) – Aug 2019 contains
Fast weight loss by Obese Adults: 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
* Start losing weight 2 months sooner if take a 50,000 IU daily for a week
3) More weight loss if also add Magnesium or cofactors
30% Improved Vitamin D response with Magnesium - a Vitamin D Cofactor
Note: Magnesium reduces weight loss by itself as well
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: 0-30% improved Vitamin D response
Obesity 1.5 X more likely if poor Vitamin D Receptor – meta-analysis Nov 2019

New guidelines on peds obesity call for aggressive treatment - Jan 2023
MDEdge
"The 2023 guidelines recommend that pediatricians offer anyone aged 12 years and older with obesity – defined as a body mass index (BMI) at the 95th percentile or higher – the option of receiving weight-loss medications in addition to ongoing support for lifestyle modifications, such as exercising more and eating healthier foods.""The same approach holds for bariatric surgery once children reach age 13, and AAP stressed that no physician should ever stigmatize children or imply that they are to blame for their weight."
