I'm fat because I don't eat enough!!!

Eat the suggested 1500 and see what happens - but make sure you get a scale and weigh your food so that you're accurate (and log everything), because it's very easy to underestimate how much you're eating!

Personally I wouldn't want to try the fasting myself, because I want to eat regularly and feel ill if I don't. I don't see that that kind of thing is necessary, but many people seem to have success on various kinds of "intermittent fasting". You might want to try just adjusting your diet for a while first and see how things go with that, before making drastic changes?

If you'd like to try some gentle exercise, trying looking up routines for things like chair yoga or "limited mobility" - I did a search for someone a while back and found quite a number of exercise that are suitable for people with disabilities or mobility issues.
