I have been on a calorie controlled diet for 3 weeks, limiting to 1800. I started at 12 stone 11. I have measured everything that passes my lips (I can be quite obsessional!) I have Wii Fit jogged 4 mornings a week.
I weigh myself at the same pre-breakfast time once a week.
I have officially lost nothing. At all. 3 weeks and not an ounce.
DH has carried on as usual, only substituting Slim Fast shakes for one workday meal (lunch) per day. He has lost 1/2 a stone. He started at the same BMI as me (and is the same height).
So sadly I have come to the realisation that I have to live with 12 stone 11 as I can't lose any of it. I recognise that I could maybe cut my calorie intake to 1500 but I also realise that I wouldn't be able to sustain that for the 6 months or so I'd need to, and my complete failure to lose even an ounce on 1800 tells me my 'maintenance' diet would have to be so strict I wouldn't be able to stick at it.
