Since November of 2011 I have lost a total of around 13 pounds, but in this last month (January) I have lost nothing. I don't know what is going on. I think I might have hit a plateau and I don't know how to overcome it. I have been eating healthy and staying within my calorie requirements as well as working out at least 4 days a week and still no weight loss. It is becoming frustrating, but I don't want to give up. I just don't know what to do since I'm not losing anymore weight or inches.
