Being overweight can be tough on the joints, so researchers wanted to know what would help more, diet, exercise or a combination of both. They recruited 454 overweight or obese adults with knee osteoarthritis for their study.
Osteoarthritis is commonly called 'wear and tear' arthritis.
The participants were split into three groups. Some were put on an intensive diet. Others were asked to exercise. While the remainder both dieted and exercised according to strict study guidelines. The goal for all was to lose 10% of their body weight over 18 months.
Of the 399 who finished the study, the diet/exercise combination made the most difference. The average weight loss was higher and the combo participants had less knee pain, better function, and walked faster.
Those in the diet only group also saw some benefits compared to the exercise only group losing more weight and reducing the pressure on their knees more.
But the bottom line, according to this study, it's a combination of diet and exercise that can literally take the weight off your joints.
