Hormone Blockers Weight gain & GLP-1s

Hello!  
I was so interested to read this as I too have put on some weight after only 5 1/2 months on Anastrozole.   And like you, I eat extremely healthily and get plenty of exercise.  I’ve been fortunate though in that I seem to have escaped the worst of the possible side effects.
I have my one year check up with the oncologist coming up next month and intend to discuss it with her, but personally I think taking the GLP-1 route would be pretty drastic.
I’m no expert but I’m wondering if the age you are at is a contributing factor to your weight gain as well?  I’m 74 and pretty much all my female friends will say that they’ve experienced weight gain from middle age onwards, despite their best efforts.   Especially thickening around the tummy region. 
I’ve started keeping a food diary to check if what I think I’m eating matches what I am actually eating, and have also gone back to swimming twice a week, an activity I had to stop obviously after the breast operation.  Hopefully that might tip the balance.

I can understand why you are so upset about the weight gain, it’s like, I’ve just had breast cancer, I don’t need this as well!
I’m sorry I can’t give any specific advice except maybe try the food diary, (I made it easy and just take a photo of EVERYTHING I eat, then go through the pics once a week and just make sure there’s nothing there that shouldn’t be).  And talk to your oncologist.

all the best
