Dec 10-11 Should you diet or not?

Main idea:

Dieting actually helps little with long-term weight control for several reasons.  First, people get back eating regular food and then turn fat again.  This yo-yo dieting situation is very bad for health. Second, some low-calorie food in fact can us to lose muscle tissue or increase the risk of heart disease.  Therefore, instead of trying to reach a certain number on the scales, developing some healthy eating habits is a better option.

Grammatical points to pay special attention to:

p.24

line 6 Say, you are looking really good.

這個say是什麼意思呢？他是要說什麼呢？
根據朗文字典，say在這邊是指
used to express surprise, or to get someone's attention so that you can tell them something
也就是他沒有什麼意思，發語詞。

line 7 drop some pound減了幾磅

也可以說lose some pound, lose weight
相反的，變胖了，我們就可以說gain some weight, put on some weight

line 14 a couple more weeks

但這邊是a couple (of)「幾個」的意思

line 16 go off the diet

我們以前學過go on a diet現在看到go off a diet應該不陌生吧？

p. 25

line 8 only to gain it all back again

to本來就有「為了要」的意思，
所以only to就是「只為了」，後面通常接不想要的後果，
例如 I rushed to school only to find that it was Saturday.

line 10 yo-yo dieting像溜溜球的減重計畫

也就是一下子胖一下子瘦

line 14 It's not worth it, though

worth it「值得」這是課本教過的片語喔，
然後though放在這邊，前後都是逗點，表示他是連接副詞，
也就是「但是」的意思！記得嗎？

line29 trim「苗條的」

我們還有學過slender, slim, slight記得嗎？
skinny意思是很瘦的，不怎麼健康的。
