Summary
低カロリー食介入中に食前500mLの水摂取を追加したグループと非摂取グループを比較した12週間RCT。食前水摂取グループは非摂取グループより平均2kg以上多く体重が減少した。水が食欲を抑制し食事量を自然に減らすメカニズムが示唆された。
Key findings
- 1
食前500mL水摂取グループは12週間で非摂取グループより平均2.3kg多く体重が減少した
- 2
食前水摂取は1食あたりのカロリー摂取を平均13%減少させた
- 3
水そのものに直接的な脂肪燃焼・代謝加速効果があるわけではなく、食欲抑制・カロリー置換が主な経路
- 4
脱水状態は集中力・運動パフォーマンス・代謝効率を低下させるため、水分補給自体の意義は大きい
