This is a good post. Thinking of it as a "diet" means you've already programmed an end. Truly changing your body for long term health means it's better to look at it as "nutrition."
"Diets" are why people yo-yo in weight. They finish their diet and go back to old habits or, worse, reward themselves with food for completing it. If your current eating habits got you to a place where you're not happy with your body, why would going back to them provide any other result?
Don't reward yourself with food. You're not a dog. Your health is your reward.
Instead, think about everything you eat as what it is going to do for your body.
