I’m 71, two replaced shoulders, one replaced hip and two knees that need replacing. I exercise gently, chair yoga etc. that said, I have lost 56 pounds in 11 months. Not in a straight decline though. Down 1 up 1, down. 4 up 2, plateau down 3 etc. the general movement however is down. Have patience, this is a journey, a new lifestyle. Don’t compare yourself to others. I never lost a lot at once or fast but I’m lighter than I was a year ago and I will be lighter next year. Keep up the good work. Every once lost is a loss and adds up. This is NOT a diet.
