The Claim
In Australian adults of European ancestry, higher vitamin D status (25OHD) is associated with higher resting energy expenditure (REE), but this association is partially mediated by improved insulin sensitivity, as measured by McAuley’s index and triglyceride-to-glucose ratio, such that insulin sensitivity dampens the relationship between vitamin D and energy expenditure.
What the research says
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.
In Australians with European roots, having more vitamin D in your blood might help you burn more calories while at rest—but if your body is better at using insulin, that calorie-burning boost might not be as strong.
See the scientific wording
In Australian adults of European ancestry, higher vitamin D status (25OHD) is associated with higher resting energy expenditure (REE), but this association is partially offset by a negative mediation through improved insulin sensitivity, as measured by McAuley’s index and triglyceride-to-glucose ratio, suggesting that insulin sensitivity may dampen the relationship between vitamin D and energy expenditure.
What the research says
1 studyThe study found that in Australians of European descent, higher vitamin D levels are linked to burning more calories at rest, but this effect is weakened a bit when the body becomes more sensitive to insulin — which is exactly what the claim says.
