I must enjoy being fat

That's the only conclusion I've come to. I mean I know all about burn more than you eat, increase your fiber, drink water blah blah blah. So why is my stomach still flabby and yucky?? I must enjoy being fat. I don't when is the last time I've broke a sweat, did a sit up or anything thats similar to exercise. I want to be fly and sexy this summer yet Im not doing anything diffrently. Isn't that the defnition of insanity? Doing the same thing over and over but expecting diffrent results.... Im disgusted
