长胖了 怪我咯

讲解：

Today's key word is Obesity¹.

Obesity 肥胖，肥胖症

Obesity is a medical condition in which excess (额外的) body fat has reached the level that it may have a negative effect on health.

Here's an example：

Sugar and fat can more easily lead to obesity than some other foods.

糖和脂肪比其他食物更容易导致肥胖.

In Western countries, people are considered obese² when their body mass index or BMI exceeds 30 kg/m2.

Some East Asian countries use stricter criteria³. BMI is a measurement obtained by dividing a person's weight by the square of the person's height, 体质指数（BMI）=体重（kg）÷身高^2（m）

Commonly accepted BMI ranges are Underweight: under 18.5, Normal weight: 18.5 to 25, Overweight: 25 to 30, Obese: over 30.

Now let’s learn the word in the news.

A recent report concluded that grandparents are a significant factor in the growing level of childhood obesity in China. They tend to over feed youngsters in their care and excuse them from taking part in physical exercise.

讨论:

近期，一项调查报告指出中国儿童肥胖率增加的重要原因是爷爷奶奶和姥姥姥爷。

他们认为，老人照看小孩时让孩子吃得太多，运动太少。

不止是儿童，成年人的肥胖率也逐年上升。

不仅仅中国，欧美国家也存在此类问题。

你对自己的身材满意吗？

有用过什么有效的减肥方法吗？分享一下吧！
