Which Michael Mosely Fasting plan?

[Damekitty]

I want to buy one of his books but would appreciate advice on which plan to follow. Thanks.
I am female, mid sixties, unable to exercise due to chronic ill health and am 4 stone overweight!

I used to like 5:2 and found it worked as long as I was relatively careful on the other 5 days. You can't just eat what you want.

A friend at work whose Mum is your age says she is getting great results on the Fast 800. I think thats the Mediterranean based one. 800 kcals a day. Sounds quite brutal to me but I know she doesn't exercise either.
