How far would a 180 pound male have to run to lose weight?

It's not how far - it's how regularly and how you change your eating habits.

You should exercise at least 3-5 days a week for 30 minutes a day (or longer if you are up to it). Either walk or jog until your heart rate is elevated, then cool down by walking after you jog until your heart returns to normal.

However, to lose weight, you must change your eating lifestyle! Cut out the junk food and sodas. Cut your portion sizes down to normal instead of "American sized." Drink more water and eat more fruits and veggies instead of carbohydrates and sweet stuff. Choose My Plate is a great website to help you learn how to eat in a more healthy way that will allow you to lose weight and keep it off.
