Why Can’t I Lose Weight?

I don’t understand why I’m not able to lose weight.  I have changed my diet completely, I have basically done a 180° and yet I still can’t lose weight.

I stopped drinking soda, coffee and tea and I only drink water but that didn’t make any difference because I’m still gaining.  I stopped making pasta meals and started eating more veggies and sometimes only eat veggies and yet that hasn’t made any difference because I’m still gaining.

I haven’t started exercising though because I’m in too much pain.  If I had a back wheel for my bicycle then I would be able to ride my bike, although it has a weight limit of 250lbs and I’m 258 now so I would probably have to wait a bit to do that.  I tried walking but I get back pain after like 5 minutes then I have to sit down.  I have degenerative disc disease in my spine which makes it very difficult to do anything really.

I am seeing the doctor this week on Thursday and I know he’s going to bitch at me for not losing weight again this month.  But nobody can say I haven’t tried because I have made the change to my diet.  Until I can get an easier way to exercise, I’m kinda stuck.
