Experts say this can lead to a medical condition called orthorexia nervosa, or addiction to 'healthy' eating and over-exercise.

专家说，这会导致一种叫做神经性厌食症的疾病，或者对“健康”饮食和过度运动上瘾。

The exception is someone that's starving and severely malnourished, or someone who is actively depriving themselves of food, like in anorexia nervosa.

唯一的例外是饥饿和严重营养不良的人，或者是主动不进食的人，比如神经性厌食症患者。

Anorexia nervosa has the highest mortality rate among eating disorders, as it is associated with an extremely low body weight, due to food restriction, compulsive exercise, or purging.

神经性厌食症在饮食失调中死亡率最高，因为它与由于食物限制、强迫运动或排泄而导致的体重极低有关。
