Senior looking for accountability and support

Options
I’m always about 10 to 15 pounds overweight. Now I’m facing a total knee replacement and I better get this weight off.
I joined MyFitnessPal three weeks ago and I’ve lost 7 pounds.
I broke my knee last January and walking is difficult but I can ride my bike and swim.
Please anyone out there send me a friend request so I can have some companionship on this journey 😊
