For example, it's said that laughing for quarter of an hour will burn up 40 kcal, and if you laughed all day you'd use up about 2, 000 calories.

比如，据说笑15分钟会消耗40千卡的热量。如果你笑一整天的话，你会消耗2千卡路里。

For 12 months, the participants were instructed to follow a calorie-restricted diet that consisted of 1,500 to 1,800 kcal per day for men and 1,200 to 1,500 kcal per day for women, according to the study.
