I started Tamoxifen 1/1/13. I started Texas Fit Chicks bootcamp in 7/1/13. And then I gained 15 pounds. I felt like I was eating good (no sugar, dairy or gluten) and I was getting 3 workouts in each week. I also walked occasionally.

In January of 2014, my trainer did some research of her own and decided that I needed to try a higher-protein, lower-carb diet. I had been eating no sugar, dairy, or gluten since I was diagnosed with BC in 2013.

But I went with her advice. I'm eating between 1200 and 1500 calories a day, around 150 grams of protein, and around 115 grams of carbs (which I don't feel is technically low carb - I think that's about 50 grams, which would make me feel deprived.) I eat no processed foods except veggie protein for my 2 shakes a day. I am doing my boot camp 3 days a week and have gained lots of muscle. And I have lost 20 pounds and 2 sizes.

I just wanted to share because I think this formula is working for me and maybe it might help one of you.

Yes every body is different. Definitely noticed a weight gain on Tamox... belly especially but then had seriously bad bouts of diarrhea and weakness from the loss of fluid. Also got headaches and higher blood pressure on Tamox. I had tried Effexor years ago and it sent to the ER with erratic BP .... Can't they develop a pill that lifts mood, keeps cancer at away AND helps lose weight ?!
Darn it ! ;-/ They are too busy playing with Viagra and Cialis for men ! LOL

Same here. At the worst, I looked like I was pregnant!

Yes! And, it's so frustrating I've noticed weight gain in my stomach and arms :(

A medication that helped me not gain any weight on Tamoxifen, was Effexor and it helped with hot flashes and any anxiety you are feeling.
