Advocare not working?

Options
I am currently pretty frustrated with my body. I have been on the 24-day challenge now for 10 days, and haven't lost ANY inches, or weight. I'm following the diet plan completely. I'm so discouraged, especially since I exercise (cardio and weight lifting) 6 days a week. I'm even considering getting my blood tested for possible thyroid issues. It doesn't help matters when I see videos of people who have been on Advocare, and have lost like 16 lbs in the first 10 days. I'm utterly confused. I've even started to change up my workout regimen with adding swimming laps to my zumba classes, treadmill, elliptical, and weight lifting. Does anyone have any tips? :(
