今天是西方的情人節(jié)，還好我是南方人 In humans, there is a fine balance between energy intake and energy expenditure.? Energy intake is in the form of food, and energy expenditure is in the form of the basal metabolic rate and physical activity.? The difference between energy intake and energy expenditure is the net energy balance. If intake exceeds expenditure, then a net positive energy balance occurs. ??注釋： ??fine balance /?fa?n ?b?l?ns/ 精細(xì)平衡；精密平衡? ??intake? /??nte?k/ 攝入；攝取量 ??energy intake /??n?d?? ??nte?k/ 能量攝入；能量攝取 ??expenditure? /?k?sp?nd?t??/ 耗費(fèi)；消耗；花費(fèi)；消費(fèi)；費(fèi)用；開支 ??energy expenditure /??n?d?? ?k?sp?nd?t??/ 能量消耗 ??physical activity /?f?z?k(?)l ?k?t?v?t?/ 身體活動；體育活動；體育鍛煉；體力活動 ??net? /n?t/ 凈得的；純的；凈的；最終的 ??energy balance /??n?d?? ?b?l?ns/ 能量平衡 ??exceed /?k?si?d/ 超過；超越 ??positive energy balance /?p?z?t?v ??n?d?? ?b?l?ns/ 正能量平衡 ??BMR基礎(chǔ)代謝率
