I was losing a pound a week, but I was hoping that switching things around would make the weight come off faster (since I still have 50 lbs to lose). So I upped the fat (from 90g to well over a hundred) and calories (from 1300 to 1900) a few weeks ago and the result was an immediate 3.5 lb whoosh. However, I then crept back up a pound (without changing my diet from the upped fat and calories) and have been hovering at the same weight for the past week and a half. My Monday weigh-in brought me back to the weight I was last Monday - only the second time since I've started on Atkins that I lost no weight in a week (and that first time was the only week that I cheated). So I'm going to try dropping the fat and calories again while crossing my fingers that I didn't screw up too badly.
