It has already been said... we reach plateaus... don't be disillusioned...

Personally, I would not be weighing myself wekkly or fortnightly, but rather over months...

I wrote a month or two back that after a year of training I had not dropped weight - but I had dropped two dress sizes... I was very disappointed to not have dropped numbers on the scales but absolutely thrilled to fit clothes that I had not worn for a few years...

Just always bear in mind that muscle weighs more then fat, and although you may still be losing fat, if you have gained a little muscle, then you may not notice a change on the scales.

Also remember the BEST and LONGEST-LASTING weight loss is that which occurs over months and months... most people who lose weight quickly will invariably put it back on... you need to give your metabolism time to adjust to new demands and to new ways of being 'fuelled'.
