麻烦来杯咖啡。这瓶咋回事呢？-我正烦呢。速效" 减肥" 呢，努力保持低调诶。

If your only priority is to lose weight, you may resort to crash diets and excessive physical activity — both of which can negatively affect your mental and physical health.

如果你唯一在意的就是减肥，你可能会选择节食和过度的运动，这两种做法都会对你的心理和身体健康产生负面影响。

But Dan, you may have also heard of a crash diet – that's where someone makes a rapid change to the types of food they eat with the aim of losing weight quickly.

但是丹，你可能也听说过速成减肥法——也就是人们为了快速减肥而迅速改变所吃食物的种类。
