Losing weight helps your knees--duh!

Thursday, May 02, 2013

Letís look at weight and your knees. When you walk across level ground, the force on your knees is the equivalent of 1Ĺ times your body weight. That means a 200-pound man will put 300 pounds of pressure on his knees with each step. Add an incline and the force is greater. The force on each knee is two to three times your body weight when you go up and down stairs, and four to five times your body weight when you squat to tie a shoelace or pick up an item you dropped.

Losing a few pounds can go a long way toward reducing the pressure on your knees ó and protecting them.

In one study, the risk of developing osteoarthritis dropped 50% with each 11-pound weight loss among younger obese women. emoticon

For men who get their body mass index (BMI) down from 30 or higher to between 25 and 29.9, knee osteoarthritis would decrease an estimated 20%. emoticon

A similar change in women of the same age could cut the incidence of osteoarthritis of the knee by about 30%. emoticon
