减肥英文怎么说keep fit

减肥英语说法为 "lose weight"。"keep fit" 是保持健康、锻炼身体的意思，并不一定与减肥有关。

例句：

(我正在通过健康饮食和定期锻炼来减肥。)

(如果我想要减肥，我需要开始更频繁地锻炼。)

(他通过严格的饮食和定期锻炼减掉了很多体重。)

"Keep fit" 这个短语可以说是在20世纪初期由英国人创造的，并且在20世纪中期和20世纪后期很流行。
例句：

I'm going to the gym to keep fit.
(我要去健身房锻炼身体。)
He tries to keep fit by running every morning.
(他每天早上跑步来保持健康。)
