Hi. I'm new to this kind of diet, but really need a o lose weight, so giving 5:2 a try and logging everything on mfp. Anyway, I planned for 500 cals and spent 58 on exercise (I'm writing a grant application so on my huge arse all day). Anyway mfp told me I had 558 cals and then I managed to go over that by about 73 (rice cakes). Does this matter or have I ballsed up on my first day?
