Fasting Diet and how many calories on other days?

mickstereftb

Hi, been using MFP for a few months now and it is great for calorie calculations now that i am using the 5/2 diet. I now have a question. (don't we all? )
I know i have to restrict myself to 600 calories on my fasting days, Monday and Friday but as my (generally accepted) TDEE is around 2300, do i have to eat that amount on my normal eating days to avoid my body going into starvation mode? It may sound a silly question but i was using my 'goal' calorie intake on here for losing 1lb a week and that was 1930 calories.
That would mean a deficit of about 5550 a week! Should i counter act this by eating up to my TDEE on my non fasting days and let the calorie deficit on my fasting days do the work, so to speak?
