I think that if your weight is affecting your quality of life, it is not ok to just accept it. If what you are doing is not working, then you need to look into other ideas - talk to your doctor about your diet and exercise program. Maybe talk to a nutritionist.
Otoh, if you are happier with sore ankles and some limits to your mobility instead of changing your diet and/or activities, then accept the weight. Be honest with yourself. It is your life.
my dad is a heart patient. He eats food he knows is really bad for him a couple of times a year because it is important to his enjoyment of life. He also exercises less than he should because he sometimes skips it to do other things that are important to him.
he always takes his medication because it is easy to do, he can afford it, and the benefits out weigh the side effects.
