You can do absolutely anything that you want to. A year ago, I was over 300 pounds and could barely walk and had to use a cane. My knee surgeon said the only way he would operate with a new knee for me would be to lose weight. January 28th I will get a new knee because I knuckled down and got to it and did what I had to do to make myself well. You can too.
No matter if you have weight loss surgery or not or you have issues or not, all you have to do is eat better. Control your portions eat better food, non fast food less carbohydrates and you will lose weight. I cannot hardly exercise much less walk so I had this success without hardly any exercise. No excuses either you do it or you don’t.
I am not letting nothing stop me. Not anymore.
Stay blessed

I guess needing a knee to walk was your wake up call. I need one, as I just ate a huge chocolate chunk cookie!! Next month I see my WLS doctor and March cardiologist, need to lose weight and move my fat ass more. I miss the gym but because of Covid and people who don’t believe in vaccines, I don’t go anymore. Yes I had my booster.
