Good afternoon Neil and Cinque,
hope you are both enjoying a relaxing boxing day.
Jelly Bones. The best source of info would be one of Michael Mosley’s books. But these links may also help:
an article about the book/program:

the website that supports the 800cal program:
https://thefast800.com/
The 800cal a day is a significant commitment that will drastically impact your lifestyle. However with such dramatic restriction to your daily calories, you will lose weight quickly. There is also research evidence that rapid weight loss combined with a Mediterranean program can reverse type 2 diabetes in some people. (This is a reason Michael Mosley gave for developing it.)
Over a longer term 5:2 is very sustainable, but it will naturally have much slower weight loss as you are only cutting back on calories for 2 days out of 7. I think that’s why so many of us have stuck to 5:2 while in maintenance as it’s easy and help us keep our weight stable. How quickly you lose weight on 5:2 varies significantly and will depend a lot on how much and what you eat on the 5 days when you aren’t restricting calories. You need to be sure you having a bit more to eat on those 5 days to compensate for the 2 days when you cut back – it’s easy to do that without even realising. Just being aware is half the battle with this.
I think Cinque’s idea is a good one. Try the different approaches and find a path you can stick to over the long term.
