リバウンド

• 読み: リバウンド
• ローマ字: ribaundo
• 漢字の分解: From English 'rebound' → katakana adaptation リバウンド (meaning specialized to weight regain in health context)
• 発音: /ɾi.ba.uɴ.do/

意味

Weight rebound; regaining weight after a diet, often ending up heavier than before.

リバウンド is the dreaded enemy of every dieter in Japan. The term, borrowed from basketball, vividly captures how weight 'bounces back' after extreme dieting. It's such a common phenomenon that it's become a standard part of diet vocabulary. Health experts frequently warn that crash diets lead to リバウンド, and the concept is central to marketing for sustainable diet programs like RIZAP.

例文

1. せっかく5キロ痩せたのにリバウンドで7キロ増えた。
2. 急なダイエットはリバウンドしやすいから気をつけて。
3. リバウンドしない方法ってないのかな。
