オートファジー
Meaning: Autophagy; the body's cellular self-cleaning process, popularized as a buzzword linked to fasting and anti-aging.
オートファジー became a sensation in Japan after Yoshinori Ohsumi won the 2016 Nobel Prize in Physiology or Medicine for his research on autophagy mechanisms. The scientific concept was quickly adopted by health media and fasting advocates who claimed that 16-hour fasting activates オートファジー, promoting cell renewal and anti-aging. While the science is real, the mainstream usage often oversimplifies the process, treating it as a magic bullet triggered by skipping meals.
Examples
- 16時間断食でオートファジーが活性化されるって聞いた。 听说16小时断食可以激活细胞自噬。He oído que un ayuno de 16 horas activa la autofagia.16시간 단식으로 오토파지가 활성화된다고 들었어.
- オートファジーってノーベル賞取った日本人の研究だよね。 细胞自噬是日本人获得诺贝尔奖的那个研究吧。La autofagia es la investigación de un japonés que ganó el Premio Nobel, ¿verdad?오토파지는 노벨상 받은 일본인 연구자의 연구잖아.
- オートファジー目当てでファスティング始める人増えたよね。 为了细胞自噬而开始断食的人越来越多了。Cada vez más gente empieza a ayunar con el objetivo de activar la autofagia.오토파지 목적으로 파스팅 시작하는 사람 늘었잖아.

✓ Do Say
- オートファジーの研究で日本人がノーベル賞取ったんだよ。 (A Japanese researcher won the Nobel Prize for autophagy research.)有一位日本研究者因为细胞自噬的研究获得了诺贝尔奖。Un investigador japonés ganó el Premio Nobel por sus estudios sobre la autofagia.오토파지 연구로 일본인이 노벨상을 받았어. (일본 연구자가 오토파지 연구로 노벨상을 수상했어.)
- オートファジーを活かすために16時間断食してるって。 (They say they do 16-hour fasts to activate autophagy.)据说他们为了激活细胞自噬在进行16小时断食。Dicen que hacen ayunos de 16 horas para activar la autofagia.오토파지를 활성화하려고 16시간 단식하고 있대. (오토파지를 활용하기 위해 16시간 간헐적 단식을 하고 있다고 해.)
✗ Don't Say
- 「オートファジーで何でも治る」は過大評価 — 研究はまだ途上 (Claiming 'autophagy cures everything' is an overstatement — research is still ongoing)'细胞自噬能治百病'是过度夸大——研究仍在进行中Decir que 'la autofagia lo cura todo' es una exageración — la investigación aún está en curso「오토파지로 뭐든 낫는다」는 과대평가야 — 연구는 아직 진행 중이야 ('오토파지로 모든 게 치료된다'는 건 과장이야 — 연구는 아직 진행 중이거든)
Common Mistakes
- Treating オートファジー as a proven diet method — while autophagy is a real biological process, the popular claims about fasting-triggered benefits are often oversimplified
Origin & History
From Greek auto (self) + phagein (eat). Became a Japanese buzzword after Yoshinori Ohsumi's 2016 Nobel Prize for autophagy research, quickly adopted by health media and fasting advocates.
Cultural Context
Era: 2016 Nobel Prize onward
Generation: 30s-50s, health-conscious
Social background: Universal
Regional notes: Used across all of Japan. The fact that the Nobel Prize went to a Japanese researcher made オートファジー especially prominent in Japanese media and national pride.
