Ditto on what Manda said. Also, have you ever overindulged on food, weighed yourself the next day and saw an increase of 2 pounds, then waited and weighed again 3 days later and it was back to "normal"? The 2 pound increase was the food sitting in our intestines. It's very difficult to lose 2 pounds of fat in 3 days. So...maybe some of that weight gain is actually food rather than fat. Glad you posted! Yes, tracking is the answer for me, too.
