Eat lots of high-fat foods and don't exercise. It's your metabolism. Look at your family photo album and see who is thin in the pictures. It's the gene pool! Eat well, but don't eat bad fats and certainly exercising (going jogging, biking, fast walking) is good for the body and will put muscle on you and get your heart rate up.
