Apologies if this has been discussed before. If it has, please point me in the right direction. I did search for the program name and the name of the presenter but didn't come up with anything. Anyway, this is quite an old program (Aug 2012) but I had it on my Sky box and caught up with it on the weekend. There were some bits and pieces about it in the papers at the time. Basically, the presenter (Michael Mosley, who is a doctor but I'm not sure of what kind) was looking at fasting as a way of 'living longer' and holding at bay various signs of ageing (cancer, heart disease etc). He looked at several methods and settled on trying a '5:2' program, whereby he eats normally for 5 days a week and 'fasts' for two days a week (on these fasting days he is still allowed 500-600 calories and water). I was really unnerved by the program initially - I was sat there thinking this is verging on promoting anorexic tendencies. However, the headline that it can reduce the risks of things that most people worry about got my attention and I began wondering more about it. For me, I don't see how it can work with an active lifestyle (ok, I have a sedantary job but I run 30-35 miles per week and also I'm generally careful with what I eat/drink). Also, I originally thought that this is not a sensible way of losing weight but on reflection the weight loss is a secondary benefit. I won't pretend to understand the ins and outs of it, but fasting in general reduces the level of a hormone called IGF-1 which (according to the program) is a good thing. It's no longer on iPlayer but the are a couple of clips (http://www.bbc.co.uk/programmes/b01lxyzc
) and there is a low quality copy on YouTube. There is loads on the Internet about it but here is an article in the Telegraph from the presenter. http://www.telegraph.co.uk/lifestyle/9480451/The-52-diet-can-it-help-you-lose-weight-and-live-longer.html
Did anyone see it? Any thoughts on this generally?
