Energy balance

In weight-stable interventions, low-fat diet and exercise do not independently improve metabolic syndrome scores; the improvement is entirely mediated by the loss of percent body fat.

If you are doing a low-fat diet or exercising to fix metabolic syndrome, the benefit you see is likely due to the small amount of body fat you lost, not the diet or exercise itself. If you cannot lose body fat, these specific interventions may not improve your metabolic syndrome score. Focus on achieving fat loss, regardless of the method.

GoodRefutesHIGH confidence
After adjustment for ΔBF, low-fat diet alone and in combination with exercise had no effect on MetS. The key component for MetS from low-fat diet and/or increased physical activity appears to be body fat loss.

Why this rating

Randomized controlled trial with rigorous adjustment for body composition, though limited to specific demographics (postmenopausal women, men with dyslipidemia).
