Hi iv been doing 5:2 for about 3 months now. Its been good iv lost about 8lb BUT i have a few questions!!
I go to the gym every day, even on fast days. I usually do a spin class and a body conditioning class which would burn about 600 kcal. On fast days, if i have already burned 600 cals, can i eat up to 1100 cals making it a total of 500, OR do i have to keep it at 500 cals no matter what?
Next question. I seem to have hit a brick wall... but getting hungrier on fast days. I havent lost for about 3 weeks any tips to restart this weight loss. Iv only got about 4lb to go!!
Thanks xx

Stick to 500 on fast days no matter what. If you're trying to lose weight then I would recommend not eating your exercise calories back on non fast days either.

Come and ask these questions on the main thread - lots of people there who'd love to give you answers!

when I tried 5;2 I found I had no energy for exercise on fast days, and as I found it hard to work on fast days too, I ended up not exercising (running)- also, I hardly lost any weight. I figured it was better not to fast and to exercise. I started cutting calories (slowly)- mostly just smaller portions and no crisps- lost about 8kg and am keeping it off. 5:2 was a big failure for me, and I remember hearing a programme on R4 some months ago where a reasearcher looked at the evidence base and was not convinced.

On a fast day I stick to 500 calories even though I swim a mile, do an hour of yoga and an hour of body pump.
You get used to it.
