自我提高法

Track what you eat.

记下你吃过的食物

Keeping track of all the food you eat and all the exercise you do in a day can be challenging, but this helped one web user see the harm she was doing to her body.

记录下你一整天里吃过的所有食物以及做过的锻炼活动，这会是一项挑战。可是这样做让一位网友了解到了，她曾对自己的身体造成怎样的伤害。

"I didn't realize how little of some nutrients I was getting and how much sugar and fat I was getting daily until I started to do this regularly," she writes.

“过去我从未意识到自己每天摄取的营养多么少，吃下的糖分和脂肪多么过量，直到我开始每天做记录。”她写道。
