Impressive results were recently presented at the American College of Rheumatology 2001 meeting (http://www.reuhmatology.org) in the Intensive Diet and Exercise for Arthritis (get it?) trial.
454 overweight and obese people (72% women) with an average BMI of 33 (e.g. 5'5" and 200#) and an average age of 66 years were randomized into 3 groups: intensive diet (maintaining >10% weight loss), moderate exercise (two 15 minute walks and 20 minutes of weight training 3 times a week) or both.
Each group lost weight, but the group both dieting and exercising lost the most.
All groups reported less pain in the knees, but at 18 months the exercise/diet group noted a 51% reduction in pain (twice the reduction of the other two). Furthermore, 40% of those in the diet and exercise group rated their pain at only 0 or 1 out of 10.
Functional status including walking speed improved in 50% of the combined exercise and diet group!
So, LESS PAIN, ABLE TO FUNCTION BETTER!
And they didn't even study the incidence of breast cancer, but we now know those women who lose weight and regularly exercise also will have fewer breast cancers.
