Dear A.A.
Thank you for taking time to post your experience and research. I too am struggling.
My "problem" seems to be a Catch-22 situation. I LOVED to work out prior to BC and TX and even walked daily during the recon process to regain stamina and maintain weight.BUT i crashed this year ..suddenly no energy.
It just not working anymore. My blood counts are OK, RBC low,I asked for B-12 shots and my PCP wont do it.I take vitamins etc but as you said my whole metabolism seems to have changed.
I was premenopausal at DX as well. Very disheartening and discouraging when one seems to make no headway!
Are you familiar with the WISER sister study?

and also this one

I sat in on a webinar a couple of weeks ago and some of the ongoing study results were presented. It compares the relationship between exercize,estrogen and breast cancer diagnosis. I am hoping that these studies will yield more information that will help us/Physicians plan the roadmap for Survivorship and healthy lifestyle.
Hugs,
Marcia
