This is very difficult to determine as it is very complex to find out.

這非常難以斷定，因為要找出答案是非常複雜的。

A balanced diet contains the right amount of carbohydrates, fats, proteins, vitamins, minerals, water, and dietary fiber to make the daily requirements of the body.

均衡的飲食包含適量的碳水化合物、 脂肪、 蛋白質、 維生素、 礦物質、水和膳食纖維，以滿足身體的日常需求。

Every one of us requires different nutrients, and this depends on our lifestyle, activities, and age.

我們每個人都需要不同的營養成分，而這取決於我們的生活方式、進行的活動和年齡。

This is why a balanced diet for one person may not be a balanced diet for another.

這就是為什麼對某人均衡的飲食對另一個人來說可能不是均衡飲食。

Balanced diet provides the energy to survive and stay healthy.

均衡的飲食提供能量以生存和保持健康。

Energy is needed to do work while we are awake and to perform activities when we are at rest or asleep.

在我們清醒的時候，需要能量來工作，而當我們休息或睡眠時，需要能量才能執行活動。

The amount of energy needed to carry on vital processes of the body when it is in complete rest is known as "basal metabolism",

在身體完全休息時進行維繫身體運作重要過程所需要能量總量被稱為「基礎代謝」，

where metabolism is the chemical reactions that take place within our bodies.

而代謝則是指我們體內發生的化學反應。

The basal metabolic rate is a measure of how fast chemical reactions are occurring when a person is completely at rest.

基礎代謝率是衡量某人在完全休息時，化學反應發生的速度。

For example, the energy required in the beating of the heart.

舉例而言，心臟跳動時所需要的能量。

Basal metabolic rate is affected by climate, body size, age, sex, and health of an individual.

基礎代謝率會受到氣候、體型、年齡、性別和個人健康影響。

Climate

氣候

A person living in a cold country tends to lose more heat in his surroundings and uses more energy in order to maintain his body temperature.

一個生活在寒冷國家的人，更容易在所處環境中失去更多熱能並耗用更多能源以維持他的體溫。

Thus, his basal metabolic rate is higher than that of a person living in the tropics.

因此，他的基礎代謝率會比生活在熱帶地區的人要高。

Body Size

體型

People of the same sex and age may have different body size and weights.

相同性別和年齡的人可能有不同的體型和體重。

It is estimated that those with a bigger build require more energy than those with a smaller build.

據估計，體型較大的人比體型較小的人需要更多能量。

Age

年齡

Growing children normally have a higher basal metabolic rate than older people because they require more energy for growth.

成長中的兒童通常擁有較老年人高的基礎代謝率，因為他們需要更多的能量來成長。

In adults, the basal metabolic rate tends to decrease slowly throughout life.

就成人而言，基礎代謝率傾向於在生命過程中緩慢地降低。

Sex

性別

Men normally have a higher heat production than women of the same body size and age, which requires more energy,

同樣體型、年齡的人當中，男性通常較女性有較高的產熱能力，因此需要更多能量，

as men usually have a smaller amount of fatty tissue in their bodies.

因為男性體內的脂肪組織通常較少。

Thus, the prevention of heat loss is less efficient in men than in women.

因此，男性體內防止熱量流失的效率較女性低。

Health

健康

The thyroid gland in the neck controls the metabolic rate by secreting a hormone called "thyroxine".

頸部的甲狀腺透過分泌稱為「甲狀腺素」的賀爾蒙控制新陳代謝率。

If someone has an underactive thyroid, it results in insufficient thyroxine and, thus, lowering the metabolic rate.

如果某人甲狀腺功能低下，會導致甲狀腺素不足，因而降低新陳代謝率。

Overactive thyroid produces more thyroxine, resulting in a higher metabolic rate.

甲狀腺功能亢進則會產生更多甲狀腺素，導致更高的新陳代謝率。

Activity

活動

If someone is very active and does heavy work, he or she needs more energy per day than a person who is moderately active.

如果某人非常活躍且從事繁重工作，他會比每天活躍度一般的人需要更多的能量。
