If you are overweight you increase your risk of knee arthritis. How do we know this? The answer is simple. A large study of 353 overweight women reported that those who lost even 5 percent of their weight over 2 and a half years were less likely to develop knee arthritis than those who did not lose weight.
It was also noted that those who had lost the weight had fewer ongoing symptoms than those who remained obese.
This is another reason to take off those excess pounds.
