This episode is perfect if you've heard claims like "diet soda spikes insulin," "artificial sweeteners cause diabetes," or "aspartame is toxic" — Layne uses this gold-standard review to separate science from fear-mongering.
If you're into evidence-based nutrition, skeptical of viral health scares, or just want to know if your Diet Coke habit is secretly wrecking your metabolism — this episode has the receipts.
