It can be frustrating when you're working out & eating right. But not seeing the results. Some of it is from muscle gain. Now that you are moving your body more. Plus treatment does change your body. I was perimenopausal before treatment. Hormone therapy put me into menopause.
I lost 12lbs when I first started hormone therapy. I was exhausted all the time. & stopped exercising. 6 months later I began exercising again. & put on 10lbs. I have since put on another 10lbs. So I actually weigh more than before my diagnosis. I have done intermittent fasting for 3 years. I basically don't eat breakfast anymore. I am going to try eating less & extending my fasting period. (I fast for 16 hours a day). As I would like to lose 10lbs.

I've found that everything has made me gain weight as far as cancer goes. Surgeries, chemo, steroids, radiation, anti-depressants, AIs, etc. all caused weight gain. I went from about 160 pounds when I was diagnosed in 2017 to 187-193 pounds now. None of my doctors are concerned with my personal weight gain because they want me to be chunky so if the cancer itself does eventually make me lose weight I can afford the weight loss and it won't make me get too skinny.

I've only lost weight one time and that was right after I finished radiation for the 4th time. I had a lot of nausea and was eating 4 or 5 small meals a day instead of 3 normal ones. My primary care doctor was concerned about the weight loss when I saw him a couple months later. My PET scan had been good right after radiation was completed. Then when I had my next PET scan 3 months later it showed breast cancer had returned and doctors said that is what caused my weight loss.

Why am I gaining weight after finishing breast cancer treatment even though I'm eating healthy and exercising?

It's really frustrating, but weight gain after chemotherapy is actually quite common. Gaining about 6 to 11 pounds after chemo is typical for many people, even when they're doing everything right.

Why am I gaining weight after finishing breast cancer treatment even though I'm eating healthy and exercising?

It's really frustrating, but weight gain after chemotherapy is actually quite common. Gaining about 6 to 11 pounds after chemo is typical for many people, even when they're doing everything right.

Your body is still recovering from treatment, and several factors could be at play:

* Recovery process: As your body heals and becomes healthier after treatment, weight changes can occur
* Fatigue effects: Even though you're working out again, lingering fatigue from treatment may have reduced your overall activity level for months
* Hormonal changes: Treatment can affect your hormones in ways that impact weight
* Metabolism shifts: Your body's metabolism may have changed during treatment

A MyBCTeam member shared similar frustration: "I walk five miles every day, and it hasn't touched it."

The good news is you're already doing the right things by eating well and exercising. Your body may just need more time to adjust. If the weight gain continues or concerns you, talk with your oncology team. They can check for other factors like thyroid function or insulin resistance and may connect you with a dietitian who specializes in post-cancer nutrition.

Be patient with yourself - you've been through a lot, and your body is still healing.
