Oh dear, I possibly didn't explain myself properly (although I think Juliusi & Carorees may have understood me at first

)
My fasting is always after the last meal on one day until breakfast the day after next, with only 500 cals in between, which I choose to have in 1 meal in the evening
(I think that's how most of us do it, with just the question of whether it's in 1 meal or 3) - so Bellalou, no problems there!
So:
Monday - eat normally until evening meal
Tuesday - 500 cals in the evening
Wednesday - eat normally from breakfast
The problem for the next fortnight is that it is defintely going to be impossible to do even 1 proper fast day (ie only 500 cals in the evening) - well I MIGHT manage it 1 day

SO, the only thing that I can really hope to do is eat a standard evening meal and then fast until the next evening meal - which is 22 (or 23) hours
Although I can clearly choose as sensibly as possible for my evening meals, it's going to be all entertaining so it's NOT going to be low cal!!
So my question was (I think) is it of any use fasting 22 hours in between goodly-sized meals like that or will I be punishing myself for no good reason!?
Such a shame, I've been SO proud of myself & getting into quite a good rhythm !
