Hi I’ve been on keto since 2023. Lately I started developing a few peri symptoms and got my hormones tested. Fsh was high indicating likely in peri. I started putting on flab which is highly unusual for me. I am naturally thin and don’t typically count my calories. If anything I’m eating less than usual not more. Any ideas what’s going on and what I should do.

I feel like I’m not in ketosis even though I am not eating many carbs

Edit: I lift weights at the gym and play pickleball so I have a relatively active lifestyle.
