You've been disciplined and focused when it comes to your eating plan -- sticking to the calorie recommendations and resisting treats. But one night -- be it a holiday event, a stress-induced feast in front of the television or a party where the drinks left you uninhibited as to what you ate -- has left you feeling guilty and defeated.
But, even if you went all out and downed an entire carton of ice cream or gorged on happy hour snacks, it's nearly impossible to eat enough in one evening to gain substantial weight. The number on the scale may rise as a result of water retention, but it should normalize after you return to a healthy eating routine and exercise regimen.
