Helen sheds 82lbs, pens a weight loss book in 10 months. Her motivation? "In August my father passed away, and as I sat there holding his hand, watching him take his last breath, I realized that I was mortal and that some day I would die, too. I had not done anything I had wanted to with my life…just wasted it away being unhappy and eating. That’s when I decided to give myself one last shot at health and happiness."
