Make A Simple Plan
If you know you're walking into a minefield, making a conscious plan beforehand can be a big help. Celebrity trainer Gunnar Peterson told Health, "I try not to give myself too many rules when at a party. Instead, I zero in on a single healthy practice. It can be anything from not drinking alcohol to skipping the passed appetizers or desserts. If you give yourself one thing, you'll likely stick to it."
