I was skeptical at first, but after using the product for 6 weeks, I'm a believer! Without making any lifestyle changes, other than using the product for 60 minutes each morning, I have lost 9lbs and 2.5% body fat over the 6 weeks. To give you a little background, at the start of my evaluation, I weighed 183lbs and had 24.7% body fat. (5ft 11In Tall) As of this morning, I weighed in at 174lbs and 22.1% body fat. In addition, I've noticed some residual improvement to my sleep....and that was the reason I originally evaluated the product. I'll continue my evaluation for 6 more week. I'll let you know where I end up at. This product may not be for everyone, but it certainly has worked for me. I'm 100% impressed...
