I've battled with the scale most of my life, and I've yo-yo dieted. Five years ago, I was able to fit into size 10 pants, and I felt good about that. But now my weight has increased by 35 pounds again, and my health is also in jeopardy, because I have high cholesterol and high blood pressure. I've gained so much weight that it takes an enormous amount of energy to be able to exercise. I can't afford a trainer. Any advice on what you've done to successfully lose weight? Motivational words would also help at this point?
