There are some folks who kind of pig out the whole day but I think the smart thing to do is to limit your indulgence to one meal or perhaps several smaller items throughout the day that you may have been craving all week.  Perhaps even find a more healthy version of that item(s) to eat instead during your Free day, and remember it;s only the one day!

Thank you for your help! I think I will tread very lightly on this day and not have a big oink fest!

It is important to enjoy your day but like wpbill said it isnt a day to binge and eat as much as you can. I have both eaten way too much and eaten far to little. Both are not good. My free days still consist of six meals space three hours apart and lots of veggies and water but I have don't stress about portions or ratios or grams of protein or anything. I'll have a little butter on a muffin, for example, or Ill have chicken wings. And most definitely I have some chocolate :)

Enjoy your free day and listen to your body.

From what I remember in the Body for Life book, the free day actually charges your metabolism so that your body knows that you are not in a storage or starvation mode.  It is set up to help you in a lot of ways, cravings, feeling deprived, etc., but also to rev that metabolism too.  So, it is definitely a plus!

All good advice above.  There is both the physiological and psychological aspect to free day.  Free day is free day.  It's a day to totally not worry about food or working out or anything else fitness related.  It's a day to have all of the stuff that you were strong and avoided the rest of the week, because you knew free day was coming and you could eat as much of whatever it is you were resisting.  Pig out if you want to and feel like you need it.  I do often on free day.  Yes, you will feel like crap, even going into the next day.  That's not a bad thing.  By the end of a free for all free day, I'm very much looking forward to eating right and exercising again.  It reminds me what I felt like when every day was free day.  However, without knowing that a free day is coming there is no way I could avoid forever all of the donuts, cookies, burgers, fries, etc that is in front of me on an almost daily basis.  

As cammie said, that extra shot of calories lets your body know you are not starving it and that it doesn't need to go into shutdown mode to conserve calories.  It definitely has a positive impact on your metabolism.

Don't feel like you have to pig out on free day if you don't want to, but don't be stressing out if it does turn into an "oink fest."    

Just remember to take responsibility for your free day.  Bill Phillips has also said that it's okay to just have 3 shakes on that day.  There isn't a need to pig out.  People tell themselves that to justify what they're doing / eating.  I'm not saying you can't eat what you want, but understand that it's because you want it and are choosing it, not because you need it.  Understanding that is part of the success here because we all need to take responsbility for our own choices.

Also, binge eating is not healthy behavior.  I've had people argue that they can do what they want with their free day and although they are correct, what they are missing is that their behavior isn't helping them move forward in the future. 

As for "re-setting" the body, an extra 200 calories in broccoli would also do that.
