The Claim

In overweight or obese individuals with knee osteoarthritis, four weeks of moderate-intensity aerobic exercise combined with dietary calorie restriction does not significantly reduce C-reactive protein (CRP) levels compared to calorie restriction alone.

Support is ahead, but a single strong opposing study can change this.

Cause and effect
1 study reviewed
In plain English

Among overweight or obese people with knee osteoarthritis, adding four weeks of moderate aerobic exercise to a calorie-restricted diet does not lower C-reactive protein levels more than calorie restriction alone.

See the scientific wording

In overweight or obese individuals with knee osteoarthritis, four weeks of moderate-intensity aerobic exercise combined with dietary calorie restriction does not significantly reduce C-reactive protein (CRP) levels compared to calorie restriction alone.

Why this might work

Losing body fat through eating fewer calories reduces the number of fat cells that release signals telling the liver to make CRP. Exercise increases muscle signals that lower other inflammation markers, but those signals do not affect the liver's production of CRP when fat loss is already happening.

  1. Study: The effects of short-term dietary calorie restriction combined with aerobic exercise on systemic inflammation in overweight or obese individuals with knee osteoarthritis: a randomised controlled trial.

    For people who are overweight and have knee pain, adding four weeks of moderate cycling to a diet didn't lower their inflammation marker (CRP) any more than dieting alone. So, the claim that exercise doesn't help reduce this specific inflammation marker is backed by the study.
