When overweight people exercise, the excess weight puts additional pressure on their joints and lungs. As you begin to lose weight, exercise itself becomes easier and more fun. Here’s an interesting fact: many believe that for every pound lost, a runner can shave two seconds off their run time in a mile.
Weight loss can be associated with weaker bone density, but that becomes a concern if you are underweight or follow an unhealthy diet.
People who are of normal weight spend less money on medical bills than people who are overweight or obese. That’s because excess weight causes a lot of health problems on its own: high blood pressure, for instance, or strained joints.
