a way of eating that involves changing regularly between periods of eating and fasting (= deliberately not eating), especially in order to lose weight

Many people have found intermittent fasting to be an effective way to lose weight. 许多人发现间歇性禁食是一种有效的减肥方法。

Dietary restriction (either caloric restriction or intermittent fasting, with maintained vitamin and mineral intake) can extend lifespan. 限制饮食（限制热量或者进行间歇性禁食，维持维生素和矿物质摄入）可以延长寿命。
