Knee osteoarthritis (OA) is a most common condition that affects millions of people worldwide. Characterised by the degradation of cartilage, knee OA can lead to pain, stiffness, and decreased mobility, severely impacting one’s quality of life. As individuals seek relief from the discomfort and limitations associated with this condition, a growing body of research suggests that weight loss is one of the most effective strategies for managing symptoms and enhancing joint health.
