135. Fasting and Fasting Mimicking Explained | Renee Fitton, Longevity Dietician

Jun 26, 2025 | Podcast Episode

You probably know what fasting is but what is fasting mimicking? In a nutshell it’s fasting whilst still eating! You’ll have to listen to get all the details, but having just recently completed a fasting mimicking diet I was excited to be able to interview Renee Fitton, Longevity Dietician from L-Nutra to help me understand what I was doing right (& wrong!) and to explain to us all the benefits of fasting and fasting mimicking. Personally I’ve had great results in the past from the fasting mimicking diet (FMD) and I’m now inspired to build it in to my routine a bit more often than once every few years!
