I am 33 yrs old and have gained a lot of weight. I am 6 feet 3 inches tall and used to maintain weight around 275 lbs. I now weigh 450 - 500 lbs and am having a huge problem losing it. I have a severe case of club foot in my right ankle. my Achilles tendon on my right foot was removed when I was young. I have had a fusion in my ankle to hold it in place. I can not jog or run. I am not suppose to do anything thing excessive on it including walking. I have arthritis in it as well. I work a desk job 45 hrs a week. I drive between 1.25 - 1.5 hrs each way to work mon - fri. I also have a family that I have to take care of. it doesn't leave a lot of time to do much. I could use all the help or advice I can get. what can I do to lose weight? what kind of exercises can I do?
