I don't think the number on the scale is the best indicator to how healthy someone is. I think a physical measuring things like fasting glucose, blood pressure, and cholesterol does a much better job. However, I am afraid we are sending a message that if you are overweight, you are healthy. This is not the case. With healthcare costs rising at an alarming rate, and more and more people forced to choose between paying for health insurance and paying for other expenses of everyday living, I think it is important for the American population to do its part in maintaining a healthy lifestyle and trying to avoid things like type 2 diabetes, blood pressure medication, Lipitor. I also think it means avoiding things like joint issues.
A study published in Runner's World magazine about a year and a half again was hoping to dispel the myth that running ruins your knees. It examined 593 runners and 423 non-runners over a 21 period. The non-runners had a higher incidence of osteo-arthritis than the runners.
It should be noted the runners averaged 60 minutes of running 5 days a week. These weren't people that were doing exceptionally high mileage and they incorporated recovery days. It should also be noted studies have repeatedly shown extra weight causes far more wear and tear on joints than anything else. Carrying around even 20 extra pounds is hard on the knees, hips, and back.
So, in my opinion, all of these studies published all over the country heralding being fit and fat are ignoring the side effects of the extra weight that aren't heart related. Having knee surgery is expensive, for a number of reasons. Not only the surgery, but the time off work for recovery, the amount of physical therapy that should be done to heal properly, and the time off work to go to the physical therapy appointments is quite an expense for the individual and the insurance company. I am not suggesting we all take up running. I am just encouraging people to look at the big picture before rationalizing the 15 pounds they have to lose.
