And my diet has not chnaged any... I'm getting a little less exercise, but not that much. I can't afford to go to the gym. And since I sustained a serious back injury in my youth, it's difficult for me to exercise without being in an enormous amount of pain. What is the best way to lose weight without vigorous exercise? I've tried diet pills and everything...

I'm getting to a weight that is unhealthy...

I need help.
