ウエスト・ヒップ比の改善:科学的アプローチ

5 分で読める·公開 2026-04-02·NBメディカルチーム

ポイントまとめ

  • ◎WHRを0.70に近づけて設計する方が、単にウエストを細くするより美しい結果を生みます
  • ◎側腹部と背中の脂肪を合わせて除去してこそ完成したウエストTラインができます
  • ◎ヒップボリュームが不足している場合、ウエストのみの改善は限界——Hip Designと組み合わせる必要があります

The Science Behind WHR 0.70

The reason WHR 0.70 is called the golden ratio is its consistent appearance in aesthetic preference research across cultures — suggesting a biological origin. Studies report that WHR near 0.70 correlates with oestrogen levels and fertility indicators, implying that aesthetic preference may be connected to evolutionary signalling.

Two Approaches to Waist Improvement

There are two ways to improve the waist line: directly removing waist fat (Waist Sculpt), or increasing hip volume to create a contrast effect that makes the waist appear narrower (Hip Design). NB applies one or both approaches depending on the patient's WHR and body type.

NB Waist Sculpt — T-Line Design

Rather than simply removing frontal waist fat, Waist Sculpt designs the flanks (love handles) and dorsal fat (bra line) in three dimensions, completing a T-silhouette visible from front, side and rear. Pre-operative ultrasound confirms depth of lateral and dorsal fat before defining zone-by-zone removal targets.
The waist line is not only what you see from the front — the side and rear combined create the real waist.

The Relationship with Hip Design

The most effective way to lower WHR is not always waist fat removal alone. Reducing the numerator (waist) or increasing the denominator (hip) both contribute to WHR improvement. When hip volume is insufficient, waist improvement alone may not bring WHR to the ideal value. In these cases, Apple Hip fat repositioning can improve both indices simultaneously.
