Hi Alberta,
Thanks for posting. Have you talked with your doctor about seeing a physical therapist (PT)? You have a bunch of orthopedic problems that make exercise difficult, and are hard on your confidence, and a physical therapist is specially trained to evaluate, treat, and prescribe exercise for all sorts of physical problems like you describe. There are I'm sure plenty of things you can do, but it would be the safe and proper thing to have an expert like a PT evaluate you. They can give you exercises to improve your balance and strengthen you while considering how you move, your current injuries or pain, and anything else that holds you back from exercising. And a big plus to seeing a PT is that you will have the confidence knowing you're doing the right thing. Once you see a PT you'll know everything that you can do safely, and most important you'll know that you are doing the right things. It's very difficult to prescribe or recommend exercise to someone who has orthopedic conditions like you do without seeing them in person. You need to know how a person moves, what their strength level is, and many other factors. You could try an activity like water class since it's less impact, but like I said, it's hard to say if that will help without seeing you. I urge you to speak with your doctor about referring you for PT.
As for weight loss, the good news is that you can lose weight without exercise by reducing your calorie intake enough to burn more calories than you consume. People lose weight all the time without exercising. You can too. You didn't post your height and weight so I can't comment specifically, but I suggest the following:
For the next week write down every single morsel of food you eat, and every ounce of beverage with calories you drink. Estimate the portion sizes as accurately as possible, and weigh and measure everything. Get a food scale and measuring cup to do it accurately. Then you can post questions with that information to the Diet Community where you can get expert advice from WebMD food and nutrition experts.
