definitely.. just make sure you're incorporating some strength training with the help of some weights and work on your core muscles(crunches, situps, pushups, plank, etc)...this will help relieve any stress that you may get in your back from running..also an increased muscle mass will help you to increase fat loss

Well in PE class at my high school we are required to run a mile in under 30 minutes whatever our physical condition. If you can do this relatively easily, push yourself to a higher goal like 28 minutes. Set goals for yourself so that eventually you can get it lower and lower and therefore burn more fat. Also if you're really into it you might look into supplements like Hydroxycut Hardcore or Animal Cuts if you want to work out more and get buff :). These supplements boost your metabolism and they infuse minerals into your bloodstream that put more oxygen in it and make you burn more fat. They also make your body burn fat instead of recently eaten food when you exercise so that if you take these and work out, you can burn off fat faster. Hydroxycut will make you lose more weight, but it will make your heart beat faster and has more potential danger and damage to your health than Animal Cuts.

Depends on how overwieght. Thats like 1 mile every 10 min. for some people that could hurt them to do so much.
