As I've told ya - sodium is a real sonofabitch. Fortunately, it doesn't take long to flush it all out of your system, but it can cause some crazy weight swings after weekends of ridiculous eating and drinking. I'm pretty sure knowing what I know now, I could put back on all the weight I lost and kick some serious ass on The Biggest Loser. Load up on salty foods before your first weigh in to protect you from elimination in week 1. Then just start count calories and walk around all week while others are busting their asses in the gym.
