Really appreciate your newsletter article on fasting from a few months ago. It's become so popular and I tried to do it a while ago and failed miserably.
A few weeks ago I bought a copy of the bestseller The Fast Diet to see what it was all about. In case you don't know, it was published as a result of the interest in the BBC Horizon documentary about Intermittent Fasting (IF), written by the programme presenter Dr Michael Mosley and journalist Mimi Spencer. I believe that fasting is beneficial, but not necessarily advisable for everyone, so I wanted to read the book to discover new information and research, but also I was curious to see if it contained any words of caution.
