Looking at different Avenues for weight loss [What more can I DO!!]

Was at the gym this morning and felt sort of depressed.  I looked at myself through the mirror on the wall and saw a person in great, fit shape, but with a pot belly.  This has been a discouraging month in the fact that I have taken more notice of the stomach.  I'm working out twice a week, riding as much as I can, and feeling great in both discipline.  However, I am still at the same weight.  Okay, I'm going to be 46 this year, but that doesn't mean sh#%!  I know for a fact that most men half my age wish they could be in as good a shape as I am, or as strong.  Steve mentioned that I need to just change my diet even more.  Wifey agreed on that also, and she will hopefully have me eat like her. She maintains a great weight (though she does do 10+ miles each weekend) This is something I really have to work on.  I'm getting ready to ride in some races at the end of the month of February and want to not be the weakest link!  Drank some tea this morning and will be trying to hydrate myself until my game tonight.
