You said u were fat before, what was ur initial body weight?? I do not know if u are aware, ur body mass index score is only 20.3, which means that u should be able to gain hell of a lot of weight just by eating right. If u are trying to gain weight, up ur carbs, if u are only eating 75 grams of carbs, ur body is going to burn most of the protein that u eat for energy. Dont even consider using sauce until u get to atleast 24 point mark on the BMI at ur current bf.
