An honest comparison
Extended Fasting (3-7+ days) vs Paleo Diet
Extended Fasting (3-7+ days) and Paleo Diet 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."
At a glance
| Metric | Extended Fasting (3-7+ days) | Paleo Diet |

Who should pick Extended Fasting (3-7+ days)
Extended Fasting (3-7+ days) fits adults who healthy adults with no medical contraindications who want to experience extended fasting once or rarely.
Who should pick Paleo Diet
Paleo Diet fits adults who adults with autoimmune symptoms (paleo's grain/legume/dairy elimination is functionally an aip-light), people who want a structural rule against upf, those who enjoy meat and vegetables.
The honest verdict
Extended Fasting (3-7+ days) scores 2/10 on sustainability and 4/10 long-term, with emerging evidence. Paleo Diet scores 6/10 sustainability and 7/10 long-term, with moderate evidence. Paleo Diet edges ahead long-term in our reading. 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.
