Just curious, spiceyfish - do you really eat only protein - nothing else?

The fat will come off of it's own accord and in the order it wants to. Unfortunately you can't spot lose fat from your body without surgery.

Excessively muscular calves after only 3 weeks of WALKING? wow. If your metabolism can build muscle that fast without any other resistance training I wouldn't worry about your thighs and buttocks - you use those muscles to walk, too. They'll catch up to your calves. Muscles doen't turn to fat, they just get smaller if you stop using them.
