IMHO if you make a BAD FOOD choice, it is just that - bad food and completely your choice. You can choose to eat the right things, or you can choose to vary for whatever reason. Variations are sometimes desired rewards psychologically, but physically once your body gets used to this new way of life, your body won't treat them like rewards. It may have a nasty way of getting back at you - bloating, indigestion, more cravings, not feeling "on".

I personally don't believe in this "cheating mentality", or "falling off the wagon", or worse, "falling off the wagon and restarting on induction/intervention tomorrow." If you make a bad food choice, then make your very next food choice that same day a good one. To heck with "tomorrow is a new day I'll get back on the wagon. " Today is a new day too!
