Self-help ✦ Penny’s Take
The Longevity Diet
Dr Valter Longo · 2018
82/100
👍 Worth It
Valter Longo is one of the few longevity authors whose dietary protocols are grounded in his own published research rather than borrowed from other people's labs, and that shows in the specificity and credibility of the fasting-mimicking approach. The international bestseller status reflects genuine public resonance. Anyone with existing health conditions should work with a doctor before starting the protocols, but as a science-backed guide to eating for a longer healthspan, this is near the top of its genre.
