Ha, So I thought when I binged on a whole 250g block of dark
chocolate with rum and raisins for two days. I didn't gain any
weight that four days, neither did I lose... and I know my low
carb, low fat, high fibre, high protein is helping.
And you know what happens when you binge and get away with it? You
continue.
So I toned down but continued my chocolates, sometimes relaxing to
milk chocolates. Then suddenly, one morning, I noticed my weight
creeping up, but I can't stop my binge. 
That's it, I gained 3 kgs over my 49 kg. 
So it has to be ocassional bingeing....
or none.
