I received this comment from my daughter, which might help everybody:

The only comment I will make is not to call this a diet - don't say you're going on a diet - the word itself almost invites failure. Instead tell everyone you're going on a healthy eating plan. Oh and you should always have a little fat in your diet, it's in the healthy food pyramid after all. Just as long as it's the right type of fat/oil.
Good Luck.
