my TDEE comes to @ 1500 per day but sites say this is to maintain current weight. This would give me @ 10, 500 per week to maintain. If I do two 500 fasts, im still taking @ 9,500 per week. I seem to do ok on 500 but could easily do a 700 day every other day with maybe the remaining days at my TDEE or at 1200? I know this is nt strictly the principal of 5 : 2 but am amazed how well I can feel on 500 and significant reductions on other days -all achieved by less wine n no crisps n nonsense. Any thoughts? Does anyone do one fast on, one fast off?

thanks simonco – I ma bit overwhelmed with all the data 🙂 and I can add up – but obviously not correctly :):):) xx thanks for your help. I ll check out the SDF too – think that might be the way to go for me. I’m finishing today on 588 but I ll probably be another 80 cals on top – 668? Guilty pleasure at bedtime – I read before I fall asleep n my sugar free polos make me feel naughty and nice as me and the detectives solve a paperback mystery !! ADF at 700 alt days might be best .
