Surely there must be loads of calorie-counters out there, though I suspect many are CC via 5:2.
I'm CC'ing for 49 days, to the start of the DC's school hols. (Am only on day 45 but started at 12/1, was 11/11 this morning!) I am 'on' 1300 a day but must say I've been under-eating quite a lot so must increase a bit.
