Halt the Salt

Eating salty foods causes you to retain water, since your body holds on to more H2O to dilute the extra sodium. The end result: you feel puffy and bloated, which is the last thing you need post-cocktails and cookies. For the next few days, be extra conscientious about skipping the saltiest offenders like deli meat, soup, canned foods, cheese, and salt-laden condiments, and avoid using the salt shaker completely. Opt instead for naturally low–sodium foods like fresh vegetables and fruit, yogurt, and unsalted nuts and seeds to satisfy your hunger and slim your stomach.
