Episode notes
Healthy Weight Isn't A Fixed Thing
- There is no single objective "healthy weight" anyone can point to for every person.
- Asher Larmie argues weight categories are socially constructed, not biologically fixed.
How Medical Cutoffs Are Decided
- Medical 'cutoffs' like blood pressure thresholds are expert decisions based on evidence and trade-offs.
- Larmie contrasts this rigorous process with the weak evidence base for weight cutoffs.
No Proven Health Benefit From Losing Weight
- Unlike blood pressure, weight lacks strong causal mechanisms linking it to disease.
- Larmie states there is no high-quality evidence that losing weight reliably improves health outcomes.
