I hope your injuries heal smoothly and quickly.
80% of weight management is nutrition. I have been sidelined with injuries so you do have my empathy. Eating at low end of calorie range when unable to workout is what I do.
When I include fiber and protein with clean eating (no meat) I find that hunger vanishes and stays in balance. I have a theory that I over ate (and got fat) because my body was always craving nutrients it was not getting. It worked for me to go vegetarian 90% of the time with sustainably caught fish (pescatarian) about once a week.
Hope this helps and get well soon!
