My little lady is exactly the same. To me she looks perfect but in her head she look fat...
I read a little earlier in the thread that untoned can appear to be floppy and no amount of "trimming your intake" is going to fix it, it will with the weight itself but not with its appearance. The only way to make yourself feel better is by getting your lazy arse to the gym <img src="i/expressions/face-icon-small-wink.gif" border="0"> or buy yourself some equipment (Hire purchase for equipment is the same if not cheaper than Gym membership), sweat it out for 45mins a day.
It can only help with your lung function too...
