“Every extra pound of weight you have additional pressure put on your weight bearing joints.  Every extra pound overweight is 4 pounds of pressure on the weight-bearing joints, like your knees and hips.”

Scott Zashin, MD, a board-certified rheumatologist and clinical professor of medicine at the University of Texas Southwestern Medical School.

“Being just 10 pounds overweight increases the force on your knees by 30 to 40 pounds with every step you take,”

Kevin Fontaine, PhD, assistant professor of rheumatology at Johns Hopkins University.
