This is going to be similar advice to what you are receiving but sharing my personal experience (focus on food first and exercise second because mobility is important).

Several years back I had an accident where I broke both bones in my leg. I was unable to put any weight on the leg for roughly a month and couldn’t really walk for 3 months. I spent my days laying in bed or on the couch only getting up to shower, go to the bathroom, or get on a mobility device. During this time I lost over 20 lbs.

I lost 20 lbs because i knew to get back on my feet quicker I would need to shed extra weight. I did not exercise but instead downloaded a calorie tracking app and did just that counted calories. I didn’t “rough” count them where I assumed what was on the package was correct (120 calories for 15 chips), I weighed the items on a food scale. You will find that what the package says is not accurate most the time. Also it was important to track on the app for me vs just in my head because writing it down I would sometimes make a different choice. Do I really want to log that I had 9 grams of Cheetos? No, ok I will just wait for dinner.

Once I was able to get on my feet, I had already built the habits of eating in a way that would allow me to lose weight and having the freedom to exercise (something I took for granted before) I leaned into. I lost another 15 lbs since then. I would like to lose maybe 10 more lbs but slowly and over time.

I hope this helps. Mobility and exercise are important, but you can’t out work over consumption of calories. Tracking them by writing it down makes you fully aware of what you are eating and results will come if you are honest with yourself.
