增肥英语怎么说

增肥在英语中可以用 "put on weight" 来表达。这个说法的来源可能是因为人们会在身上增加体重，就像把重物放在物体上一样。例如：

I've been trying to put on weight for the past few months, but it's been difficult.

After the birth of her child, she put on a lot of weight and struggled to lose it.

My doctor told me I need to put on weight to be healthy.

中文翻译如下：

我过去几个月一直在努力增肥，但是很难。

她的孩子出生后，体重增加了很多，很难减肥。

我的医生告诉我我需要增肥来保持健康。
