Losing weight could help protect your knees from arthritis
Osteoarthritis, which affects the joints and is considered the most common type of arthritis, is often considered a wear and tear disease. It develops when the cartilage that acts as a cushion between the bones of a joint breaks down or wears away, leaving the bones to rub against each other and cause pain, stiffness and movement problems.

The researchers noted that even study participants who lost less weight still achieved “protection against structural knee degeneration.”
The weight loss benefit was found to apply not only to overweight or obese people “but also to people with a BMI in the normal range,” they wrote. For example, those whose BMI only dropped by one unit, to a lower number on the BMI chart (from a BMI of 19 to 18, for example) were still about 5% less likely to develop osteoarthritis or see existing osteoarthritis worsen.
According to the Centers for Disease Control and Prevention, more than 32 million American adults have some type of osteoarthritis. Although the knees are the most commonly affected joints, osteoarthritis can also develop in joints in other parts of the body, such as the hands, hips, neck, and lower back.
