Hello, my name is Hawa and can I just say that you have changed my life! When I came across your YouTube channel, not only was overweight but I was also tired of trying different diets that didn't work. So thank you for helping me. When I started this program, my weight was 215-220 pounds and now I'm between 160-165. My goal is to be at 145-150. One that does concert me is that it's getting a lot harder for the weight to come off now.
