IPOARM and Post-Menopause

I have been reading and re-reading the IPOARM posts and it sounds like great advice. I have been very frustrated over the last 18 months because I have not been able to lose any of the 20+ pounds that I have gained after having retired. I am 57 years old and post-menopausal and feel that both of those facts are working against me.

I would like to know if anyone has had any experience using this method post-menopause and was it successful?
