just popping in to say that unbelievably, i appear to have lost 10lbs in the past fortnight doing BIWI's bootcamp right here on mumsnet!
i've never managed to lost more than a few pounds before by starving/restricting - and never managed to stick to anything this long before. but the best thing is, it doesn't even feel like a diet!
and even if it IS just water weight and i'm going to end up a shrivelled old prune, my stomach is so much flatter now and i'm really noticing a difference in my clothes. at my heaviest i was 11.12, started exercising regularly and got down to 11.7 before joining bootcamp here a fortnight ago, scales showed 10.11 this morning, the first time in YEARS i've been in the 10's.
do go have a gander, everyone is really supportive and there are many long-term losers whose experiences are so encouraging; loads of links to supporting evidence for this way of eating; there's a recipe thread to go with, and a questions thread too.
i'm sure if you don't get into this particular dress for this event you can find something else to wear that you'll feel fab in, but keep the dress as an incentive to lose the weight?
wishing you the best of luck! i know all too well what it's like to have a wardrobe full of clothes that 'almost' fit...
