And a concrete, from me, a very recent chat (literally minutes ago):
The obese girl: "我真的看起来很明显的胖吗?" ("Do I really look noticeably fat?)
Me (after answering her many other similar questions): "我已经不好意思回复这个问题。你问了我几次,我回复了实话的。
就努力开始:多点水,少卡路里,多点运动。
别浪费时间问人家你“很明显的胖”, 因为人家,大多数,是骗人的,她们大多数会说”你挺好,没事。“ 相信我:你真的,真的,真的要减肥。这个是实话的,清楚。 (没有必要再问我这个问题。如果我说我觉得你25%多,肯定是明显的。所以,就开始努力的减肥。)"
"I'm already getting nervous (shy; awkward) to reply to this question. You asked me several times, and I answered the truth.
Just try to start: more water, fewer calories, more exercise.
Don't waste time asking others that are you "obviously fat", because most of them are liars, and most of them will say "You are fine, nothing wrong with your weight. " Believe me: you really, really, really need to lose weight. This is true and clear. (There is no need to ask me this question again. If I said that I think you are more than 25% (you're heavier 25%+ than the normal), it must be obvious. So, start trying to lose weight.)"
