You know, there are some men out there who encourage their wives to gain weight so they don't have to worry about them being attractive to other men. That way they are sure to keep their woman!
If YOU are happy with your weight gain, so be it. But think what you are doing to your body healthwise. You are still young, but if you continue this pattern, you will be setting yourself up for diabetes, heart trouble, etc., in the next few years.
