I know the feeling. Personally, I find it easier to commit if I know exactly what I'm committing to. So, for example, instead of "go to the gym regularly", try "go to the gym three times a week". With dieting, small steps can be very helpful. For example, here's a commitment you could make: at least once a week, at the grocery store, buy something healthy that you don't usually eat, and then eat it at one meal. And don't kick yourself when you find yourself off the wagon, just get back on it. Good luck!
