I am not overweight, my BMI is within the healthy range. I'd like to lose about 10 pounds to be on the lower end of my BMI. I always watch what I eat, don't eat junk and try not to go over my calorie range. About 3 weeks I found Zumba and do about 5 classes a week. I love it. However, I have not seen any weight loss, in fact I gained a few pounds and I have not lost any inches either. This is so frustrating, I know it's only been 3 weeks, but if I'm doing everyone right, why is the weight not going in the other direction? Any thoughts?
