Seven out of 10 Americans are obese or overweight, and it’s not getting better. 56% of our children, it is estimated, will be obese by the time they are 35. Our poor choices, that didn’t seem to matter much at the time, begin to matter a lot. Over time, it becomes death by a thousand poor choices. At some point, there is no next breakthrough. No next cure known, or pill that will help you lose weight fast. So, can you lose weight by exercise alone?
