The Claim

In Australian adults of European ancestry, the total effect of vitamin D status on resting energy expenditure is not statistically significant after adjusting for insulin sensitivity and other covariates, indicating that any direct effect of vitamin D on energy expenditure is small and likely counterbalanced by its indirect effects mediated through insulin sensitivity.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

In people of European descent living in Australia, having more or less vitamin D doesn’t seem to change how many calories your body burns at rest — any small effect vitamin D might have is probably canceled out by how it affects your body’s insulin response.

See the scientific wording

In Australian adults of European ancestry, the total effect of vitamin D status on resting energy expenditure is not statistically significant after accounting for insulin sensitivity and covariates, suggesting that any direct effect of vitamin D on energy expenditure is small and likely offset by its indirect effects through insulin sensitivity.

What the research says

  1. Study: Hypothesized pathways for the association of vitamin D status and insulin sensitivity with resting energy expenditure: a cross sectional mediation analysis in Australian adults of European ancestry

    The study found that vitamin D doesn’t directly change how many calories you burn at rest — instead, its effect goes through how well your body uses insulin. Once you account for that, vitamin D’s overall impact on calorie burning is too small to matter.
