Updated October 2026

Quick Answer

Soy Protein Muscle Mass Meta-Analysis has evidence relevant to benefits, uncertainty, and practical interpretation, but conclusions should stay close to the cited sources. One representative finding is: However, evidence regarding long-term dietary adaptations and their association with body composition in overweight women remains limited.

Key Takeaways

  • 01However, evidence regarding long-term dietary adaptations and their association with body composition in overweight women remains limited. [Berg A (2026)]
  • 02Results: Both groups significantly reduced daily energy intake during the first 12 weeks. [Berg A (2026)]
  • 03However, only the intervention group increased body weight-adjusted protein intake (+0.22 ± 0.29 g/kg/day), resulting in a significant between-group difference ( p = 0.004). [Berg A (2026)]
  • 04Background: High-protein dietary strategies have been shown to support weight reduction and improve body composition during lifestyle interventions. [Berg A (2026)]
The current Migaku evidence database contains 2 reusable source documents for Soy Protein Muscle Mass Meta-Analysis. This answer focuses on benefits, uncertainty, and practical interpretation. - However, evidence regarding long-term dietary adaptations and their association with body composition in overweight women remains limited. [Berg A (2026); evidence level 4] - Results: Both groups significantly reduced daily energy intake during the first 12 weeks.

[Berg A (2026); evidence level 4] - Results The intervention group showed preserved calf circumference, while the control group experienced a decrease (W12-W0: Intervention, 0.56 ± 0.22 cm; Control, -0.91 ± 0.26 cm, p (interaction) (interaction) (time) (interaction) (interaction) (interaction) (time) (time) (time) Conclusion A soy protein-rich intervention improved muscle health in older adults through beneficial gut microbiota. [Wu X (2026); evidence level 4] Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording. This page is educational. People with medical conditions, pregnancy, medication use, or unusual symptoms should ask a qualified clinician before changing supplements, medication, or treatment routines.
