We've all been there. Sunday afternoon at a poolside BBQ, looking good, feeling good, body in the best shape it's ever been, a month or so into your new workout regimen, and suddenly somebody shoves a paper plate loaded with potato salad, grilled sausages oozing fat, a pile of potato chips, whatever. Or maybe it's the day of a big game, and your buddy is serving up six fresh pizzas along with soda. Or you're driving home late, you're exhausted, and you decide to just hit a Drive Through and pick up some junk food to go. Either way, everybody ultimately gets tempted to break their nutrition plan and eat junk. Accept that this will happen to you, accept that you'll be tempted, and then ask the question you'll immediately ask as you look down at that unhealthy food: how bad is one cheat day?
