Lose a pound in weight

Excess weight is strongly correlated with joint pain, mostly because of the stress it places on these vulnerable parts of the body. Even shedding a pound can make a difference.
A landmark study in the journal Arthritis and Rheumatism showed that for each single pound of body weight lost by people with osteoarthritis pain in the knee, there is a 4lb reduction in knee loading, says physiotherapist Sammy Margo.
That equates to the same sort of kneepounding you d experience if you walked 4,800 miles.
