Weight loss lowered some inflammation markers more than diet alone

A controlled-feeding trial in people found greater reductions in certain inflammatory markers with calorie deficit-driven weight loss than with diet alone.

Studied:
Study of people, against diet alone
What changed:
Calorie deficit-driven weight loss lowered certain inflammatory markers more than diet alone
The catch:
Inflammatory markers were reported, not clinical health benefits
Why it’s aging research:
It bears on staying healthy in midlife and later life.

In a controlled-feeding trial in people, weight loss driven by an energy deficit—eating fewer calories than the body uses—lowered certain inflammatory markers more than diet alone. The article summarized this finding from Warmbrunn and colleagues.

Mediterranean diets and fasting may improve health and reduce inflammation. But Mediterranean diets often also lead to weight loss, making it difficult to separate the effects of food composition from those of losing weight. The trial addressed that distinction. Its reported finding favored energy deficit-driven weight loss for lowering certain inflammatory markers, not necessarily for every measure of inflammation.

Why it matters

For research on inflammation and healthy aging, the report highlights the importance of separating the effects of food composition from those of weight loss.

Caveats

The abstract reports changes in certain inflammatory markers, not clinical health benefits. It does not give the size of those changes or describe the participants, limiting interpretation of their magnitude and applicability.
