Normal, hormone related. Get some L-glutamine and take with meals. Eat a little more fat and higher fat protein. Or you can do CAD for TOM and go back to Atkins afterwards. CAD is not Atkins with a Reward Meal so it would be best to print out the cheat sheet and familiarize yourself with all the rules and strictly apply them during TOM. Otherwise you can gain weight. If you use CAD during TOM and Atkins otherwise, you might continue to lose weight during that time. It might be a strategy that would work for you.
