New to 5/2

Options
Hi
Have been on weight watchers for many years but since moving to France have found it impossible. They use ready meals here which I will not touch. I started calorie counting using MFP then took the decision to begin 5/2. So far I am finding the fasting really easy but know I am eating too much on the feast days to lose weight. I only have 7lbs left to lose but feel 5/2 will be better for maintaining and not being a diet bore. Do you all calorie count on feast days? I am waiting for the good Dr M's book to arrive but all the stuff I have found on the Internet so far does not answer my question. Today I am going to allow 1200 calories. I fast Monday and Thursday.
