What is a good way to lose weight? I makes it hard for me to walk a long way at for a long time

Nutrition & exercise. Best way to lose weight is slowly over time. Don't plan on dramatic loss. Change your eating habits. Research DASH, Mediterranean & vegetarian diets (most studies demonstrating health benefits). Develop habit of doing something every day, even if only for a few minutes. Gradually build up duration & intensity. Check w/your Family Doc to make sure you're otherwise healthy. Good luck!
