I have been gaining weight recently... I am 5'7" and I was 125 lbs before I started PB and I stayed at that weight for 18 months. Now I am gaining weight, and my clothes don't fit. When I found out I had gained 10 lbs on Dec 28th, I started to count carbs again right away. I have been having 50 to 80 g a day for the last 18 days and I still gained 5 lbs. I am fasting 12 -13 hours a day. What is wrong with me? Has this ever happened to you?
