Is there good evidence that Bulletproof works?
Nidari rates the evidence behind Bulletproof’s primary claims as limited / unproven — that is the current weight of peer-reviewed research for those claims, and nothing more. This one is included for completeness — the evidence does not strongly support its specific claims, and we’ll always tell you so.
How does Nidari adapt Bulletproof?
We’re skeptical of the marketing — but if you like a keto-style rhythm, we’ll design an evidence-based version that fits your day.
