Meaning

Fasting, especially intermittent fasting practiced for health, weight management, or detox purposes.

ファスティング surged in popularity in Japan through health and beauty influencers, often associated with 16時間断食 (16-hour fasting) or オートファジー. While traditional Japanese Buddhism has fasting practices, modern ファスティング is influenced by Western intermittent fasting trends. It's positioned as both a diet method and a wellness practice for gut rest and cellular renewal.

Examples

1. 16時間ファスティング始めたら体が軽くなった気がする。 I started 16-hour intermittent fasting and I feel like my body is lighter.
2. ファスティング中だから昼まで何も食べないの。 I'm fasting right now so I'm not eating anything until lunch.
3. 週末だけファスティングするプチ断食ってのもあるよ。 There's also this thing called mini-fasting where you only fast on weekends.
