Michelle, look, this is just one of many, MANY challenges you're going to face with food throughout your weight loss and maintenance. So you have to get YOUR head in the "game."
How much do you want to lose the weight? How much do you want to be thin and healthy for life? Are your goals worth it to forgo all the fattening food while you're tailgating or at other times and celebrations involving food this year, next year, and for the rest of your life? That's the question you really need to be focusing on.
Is it going to be difficult? Yes. Is it impossible? Not at all.
Fine, you want to tailgate, you can bring the lunch kit with you. You want to have something that's grilled? Fine, bring a turkey burger. Want fries? Make carrot fries. Want chips? Bring some JC chips or popcorn. Pack up some fruit for yourself.
It's what - five - six hours out of your life, or more to the point, out of your week. Are you willing to possibly screw up a week's worth of eating well just so you can pig out on Sunday? Does that sound like it's worth it?
So what if the Giants move ahead and there are other playoffs and Super Bowl parties. What are you going to do? Backtrack on all of your work? It just doesn't make sense.
The Giants trained long and hard to get where they are. They (and their families) undoubtedly made A LOT of sacrifices for them to get this far. How much do you want your dreams? Aren't your dreams worth fighting for and sacrificing for? More to the point, aren't YOU worth making some small sacrifices for?
No one is saying that you have to be a martyr but you do have to be smart. So make a plan, pack your food and focus more on the people - the tailgating players - more than the food. THAT is going to be YOUR victory!
Tailgating is fun and it's very exciting to have your team in the playoffs, but I don't think it's necessary - IMHO - for you to blow it all (for days or a week) just so you can "celebrate." You can cheer the Giants and have fun but you have to figure a way to do it smartly. I think you can do it. I hope you BELIEVE you can.
