"I cheated on my diet"Really?
What does that mean?
Does that mean you ate a food that was high in calories? That you used food for a role other than fuel?
Isn't that just a choice?
Sure I believe that all choices need to be informed, and to inform a dietary choice, if weight's a consideration, quantity and calories may well matter, but the simple fact that you decided that food was a pleasure in your life? Well if you can't make that choice from time to time I'd argue you're cheating on living a realistic life, and that cheat's probably more likely to lead your diet to fail than any other.
