How do you make up for a few days of gluttony?

I’ve gained 3-7 pounds in the last few months from eating tasty holiday food so I’m looking for ways to make up for it. I’ve tried decaf coffee, matcha green tea, supplements, removing milk from my drinks, cutting out honey, eating yogurt every day. What else should I do?
