I’m a newbie around here but have decided to go for it after seeing a friend do so well. I tried the 5:2 a couple of years ago but found I was eating more than usual on my non-fast days! I think I am an ‘all or nothing’, type person so I am going to go for the 800 and see what happens! I haven’t got high BS but I do put on a lot of weight around my middle very easily. I have fibromyalgia and a hiatus hernia and feel more unhealthy and weary than I have for many years. I’d love to hear from anyone who has either of these issues and seen success! Any top tips very gratefully received!!! 🙂
