根據使用者的年齡 And by using the patient's age,

性別和體重 gender, as well as weight,

我們可以得出 we can actually calculate

其體內有多少是脂肪 多少是肌肉 how much of his body is fat and how much of his body is muscle.

你的體脂率為7.6% OK, so your percentage body fat is 7.6.

所以你屬于極瘦這一類 Which puts you in the ultra-lean category for men, OK?

根據Bodpod的測量結果 According to the Bodpod,

醫院行政管理人員里奧·丹尼特 hospital administrator Leo Dennett

他的體脂率在所有志愿者中是最低的 has the lowest percentage body fat of all the participants.

醫學生凱瑟琳·漢農 And medical students Catherine Hannon

和維多利亞·帕格納最高 and Victoria Pagner have the most.

她們的體脂率都超過了20% In both their cases, fat makes up at least 20% of their body.

從今天對志愿者的檢查結果來看 What we saw today in the volunteers

男性的脂肪比例是女性的一半 is that the men had half the amount of fat than the women,

對于絕大部分人來說 也是如此 and that is what we would expect in the general population.

為了達到實驗目的 For the purposes of the experiment,

每名志愿者的日常卡路里需求 each volunteer's normal daily calorie requirement

已根據其生理數據 has been calculated taking into account

計算出了結果 their physiological statistics.

接下來的四周時間 These individual figures have then been doubled

他們每天需要攝入的卡路里 to work out how much each of them will be eating

是這個數字的兩倍 over the next four weeks.

他們也被禁止從事一切 They're also banned from doing any physical exercise

可能干擾實驗結果的運動 that could skew the results.

他們將佩戴計步器 They're also going to carry pedometers

好讓我們記錄他們每天走了多少步 so that we can keep track of the amount of steps that they make,

而且我們要求他們一天不允許超過五千步 and we ask them not to walk more than 5,000 steps a day,

也就是三公里左右 which roughly corresponds to something like two miles.
