An honest comparison
Vegan Diet vs Whole30
Vegan Diet and Whole30 both target weight loss and metabolic health — but through different mechanisms, with different evidence bases, and for different populations. The honest comparison favours one over the other only for specific reader profiles; for many adults, the right answer is "neither, here's what fits."

The honest verdict
Vegan Diet scores 6/10 on sustainability and 6/10 long-term, with moderate evidence. Whole30 scores 5/10 sustainability and 6/10 long-term, with emerging evidence. They're roughly equivalent long-term in the literature. The choice should be driven by which one you can actually sustain.
Why both might fail you (and what to do instead)
Both can fail when the underlying drivers (sleep, stress, ultra-processed-food saturation, metabolic adaptation in repeat dieters) aren't addressed. If you've already tried both or one and bounced, the issue isn't macros — it's protocol fit. The Metabolic Damage Assessment maps your profile to a starter protocol that addresses the actual gap.
