Keep It Green
At a potluck or cocktail party, choose appetizers like vegetables, fruit, sushi, seafood, rice wraps, etc. instead of Swedish Meatballs and Buffalo Wings. One little bite is probably enough of those anyway.
As You Were
"Saving up" for a big meal spells disaster. Headaches and crankiness are only the beginning of starvation's retort. Even the idea behind it is whacked.
"I know… Let's go hungry all day long and get super shaky and tired just so we can shovel it in like uncontrollable carnivores at our big meal and then have a giant stomach ache and fart and moan the rest of the night!"
No, no, no. Don't go hungry. Eat as you would any other day. Remember, it's only turkey! You really can have it anytime you want!
It's My Party
Throw your own party and stay in control of the food. Assign specific dishes that fall into your nutritional agenda for others to bring. And when the night is over, pack it up and send it home with them! If it's not in your fridge, it's not in your mouth.
