Many eager patients have asked whether it’s necessary to buy the products and use them under supervision, or whether they can just do the FMD themselves at home. I always answer the question by first reminding people that half of my program, the everyday Longevity Diet part, consists of foods that can be purchased in any supermarket and does not require supervision or specially formulated products. The Longevity Diet alone will help prevent and treat many diseases, and will also reduce the recommended frequency of the FMD.
