Hi there!...i'm new to ClubRR..and wanted to share a little information on dieting and a reason why it does not work for some woman...we all know about our thyroid levels but there r more hormonal problems that women have that effect weight dramatically and maybe we r not so well informed...in one year i gain 100lbs. with extreme fatigue and suppressed appetite...it took 3 years for doctors to find my problem and now 8 months in with just one tablet a day, i lost 60lbs...i think rachel should have a show regarding women's hormones other than thyroid...like prolactin..and head traumas that can affect the regulation of your hormones- like me, for example. We, as woman have alot to care for and the more education we receive, the faster we can recognize what type of problem we have and get it addressed medically. I hope this helps someone who maybe spend years trying to figure out what was wrong, like me. Sometimes motivation and diet r not the only thing we need.
