I weighed in at 91.6kg this morning, still stuck in the 91-92kg range. One thing I have noticed is that, since I've significantly upped my miles this past month, I've been feeling a lot hungrier a lot of the time.
Do you have access to the sort of scales that assess your fat / muscle mass? We have Boditrax in my gym, and while I know they are not perfect, I do find some consolation in my wieght not going down when the balance between these two is shifting to more muscle, less fat.
So you at least look trimmer even at the same weight cos muscle takes up less space than fat. Building muscle is not a bad thing.
