Yogurt + Berries
Even though you may not have the appetite for it, you'll want to eat breakfast, as it's key for jump-starting your metabolism. Keep it light, though, to go easy on your stomach. Hassick's go-to is Greek yogurt topped with berries. Yogurt contains beneficial lactobacillus bacteria that can help keep you regular and reduce gut inflammation triggered by sugary foods and alcohol.
Green Tea
If you need a subtle energy boost in the morning, sip some green tea. This brew is rich in antioxidants, which can help prevent cell damage induced by too much junk. There's also some research showing green tea helps stabilize blood sugar levels and dulls cravings, which is important if you've overdone it on sweets and alcohol. (Bonus: It also boosts your immune system!)
