It's only fuel.

Eat heathly. Stay away from the junk food. Are you going to Vegas for the food or are you going for the gaming? Don't use this as an excuse to pig out on anything you want. Be sensible about your selection and choice of meals.

If you give yourself the excuse it's okay this once, you will develop bad eating habits.....just like you outlined in the other thread asking if it would be okay to eat anything for 2 months then go back on induction over and over again.
