    能量守恒

        一个人要维持目前的体重,每天每公斤体重必须吃进30至35大卡的热量。一个50公斤的人,每天吃进1500大卡至2000大卡,体重就会维持现状。如每天多吃了二百伍十大卡而维持一个月,就会长肥一公斤。相反每天少吃了二百伍十大卡而维持一个月,则可减肥一公斤;每天少吃了一千大卡而维持一个周,同样也可减肥一公斤。也就是每七千大卡热量可换一公斤肉肉。

        但是,根据一些资料显示:最安全的减肥速度是每周减肥不要超过一公斤。肥胖的人如把食物减半,大约就可每天减去近一千大卡热量,这样每周就能减一公斤。但如果您本来吃的不多,您可不能硬是减少一千大卡热量,节食减肥期间每天所摄取的食物热量不能低於一千大卡。

        人体生理上每天至少需要一千大卡的食物热量,才能从事安全而有效的运转,否则,心肌和血管平滑肌的蛋白质会逐渐流失而造成心脏血管疾病,严重时会死亡,国外常有报道因每日摄入总热量低於五百大卡而死亡的。另外,每天低于一千大卡的食物热量如维持很久,会因人体细胞由於长期营养不足而转变成癌细胞,种下数十年后得癌的不幸结局,这一点是一般人所未曾想到的。长期营养不良是得癌症的主要原因之一。相比电磁辐射,长期营养不良的危害性更大,因为人造电磁波自发明至今,收到的致癌报告仍不足以证明其危害性.但是对于孕妇,这似乎是肯定的,因为婴儿在胚胎期的细胞分裂很活跃.
