You didn't say whether you are measuring your food and tracking and whether you are eating in the top end of your calorie range or under it.
If you are working out 6 days/weekly, how intense is your effort? Are you hungry? I find it helps to eat 150-200 calories every couple of hours. I feel more satisfied, my blood sugar stays lower and I eat enough.
Also, make sure that you accurately filled in your activity level when you did your set-up for calories.
If you are working the program, the program will work.
