This randomized controlled trial investigated the effects of a walnut-based low carbohydrate diet (w-LCD) on fat redistribution and visceral fat accumulation in individuals with central obesity over 12 weeks. The study found significant reductions in trunk to leg fat ratio, visceral fat area, and body mass index within the w-LCD group, indicating effective dietary management for central obesity.
Key findings
- The w-LCD group showed a large effect on body mass index (η² = 0.399, p <0.001).
- Visceral fat area decreased significantly in the w-LCD group (η² = 0.393, p <0.001).
- Trunk to leg fat ratio also decreased with a large effect in the w-LCD group (η² = 0.174, p = 0.001).
Why it matters
Understanding effective dietary interventions for central obesity is crucial, as visceral fat accumulation is linked to various metabolic disorders. This study provides evidence that a walnut-based low carbohydrate diet can significantly reduce fat accumulation.
