Selection and maintenance

Documented roles, with access kept explicit

Inclusion requires a current institutional or official profile and documented clinical or research work involving ketogenic dietary therapy, nutritional ketosis, or closely related carbohydrate- restriction questions. Researchers with no care pathway are never presented as practitioners.

Material industry relationships found in official sources are summarized for context. An absent disclosure means none surfaced in the sources reviewed—not that none exists.

Details can change after our check date. Follow the official link before making a purchase, contacting a professional, or seeking care. See our evidence policy.
