The Word "DIET" for an 11 Year Old

I have stressed to my daughter that we are eating healthier. I don't think I have used the word "diet" during this process.  I don't want her to stress over that word.  I guess, it really comes back to my view of "diet" and the fact that it means restriction.  I am trying to get her to understand that this is about healthy eating and making good food decisions.  She knows she needs to lose weight and she wants to lose weight but I do not want her to obsess over it because she is only 11.

This morning, she called me at work and said she was making grits. She is becoming so independent. My baby is growing up.  I told her to make sure she eats a piece of fruit and drink a class of water. Then she asked me in her sweet voice "Mommy, am I on a diet?" I told her "No, we are on a healthy eating plan." Then she asked "What is a diet?" This question kind of caught me off guard because she just asked if she was on one. My daughter sometimes asks questions she already knows the answers too:) but I did tell her that a diet is restricting food and we are not restricting everything, we are just eating healthy and in moderation.  I don't know if that was the right way to explain it to her but it must have been satisfactory enough because she moved on looking for her banana.

I just want her to be happy, healthy and grow up without any hang-ups about herself.  I hope that, since she is in this program, that she doesn’t end up feeling like there is something wrong with her.  I tell her all the time, even before the program, that she is smart, beautiful, loving, helpful, that I am proud of her and any other word I can. Not only because she is all those things but because if other people call her something different, I want her to remember what I called her and not what some evil little kid called her :)
