You don't feel that you have, but do you know for sure? The best way to figure it out is to log your intake. Keep good record of your diet. More often than not, unexplained weight gain is due to an unconscious increase in intake. If that has been ruled out, it would be worth checking with a doc. Changes in hormones (pill, age, etc.) could definitely affect weight...as could other problems like with your thyroid.

I'm up about 10 lbs since last year, but I know I've been eating too much!
