Muscle weighs more than fat, right? ;-)

Plus 1lb this morning, so back up to 12st :-(
However, I've done a lot of exercise in the last week so I reckon the fat's turning into muscle (obviously, what other reason could there be?!) as I feel better physically and my clothes are looser... but I've put on a pound! I did think last weeks loss was a bit of a fluke as I actually ate next to nothing on the Sunday whereas yesterday I ate quite a lot plus a roast quite late on in the day.
Breakfast - Rice crispies (180cals)

Oooops... 2x Cadburys Heroes Bourneville choccies (47cals each according to t'internet)
Dinner - sticky chicken & mango couscous mmmmmnnnnn......! 369cals per portion apparently but I also had half of Aimee's small portion because even though I thought it was delicious, she hated it! 500cals. Oooops :-)
