I’m in the same boat as I’m coming off foot surgery and slowly recovering! My big thing is tracking and balancing as I’m also breastfeeding my 3 month old.

I relied too heavily upon exercise when I lost weight last time. I got plantar fasciitis and had to stop walking for exercise - gained a few kgs! I swore this time that I'd only do exercise that is part of my life, rather than exercising for weight loss. If that makes sense? I guess I'm saying, losing weight with just food is maybe harder? but probably not a bad way to do it. I try to see exercise for strength and health. Good luck with your hip replacement, I have arthritis in my hip, I've been told I'll need one eventually! I'd guess you need seated things...like seated yoga, or maybe seated upper body weight training? But hopefully by being less active you'll also be less hungry.
