I am also considering Michael Moseley's Mediterranean 5:2 diet, where he advocates eating stuff like oily fish, vegetables, Greek yogurt, EV olive oil etc...
Mrs Secure said the fasting days should be back to back, but I think that might be a bit brutal.
I am limited as regards walking, but I could cycle 45 minutes semi-briskly.
Did my first ride out the other day in 13 years and was a bit wobbly...was out for around 40 minutes and when I got back and dismounted, my body did an impersonation of what it felt like when I dismounted at the finish line in Blackpool (having started in Manchester) all those 13 years ago.
Sounds like you should be posting daily doggy bags over to Mottie Mansions...!
