在女性进入30日后,尽管用餐量与以前相同,但这个数字逐渐变胖。特别是,大量的脂肪在胃和背部积聚。人们常说“你长大后很容易发胖”。为什么是这样?这种情况实际上与基础代谢有关。

首先,基本代谢是什么?

所谓的基础代谢是指维持人体正常功能所需的能量。例如,维持人体正常体温的循环,心跳,吸吮,肌肉活动,大脑思维等都是人体机器人的基础代谢。即使人体无所作为,基础代谢仍在继续。无论是在工作中还是在睡眠中,基础代谢都不可能在24小时内中断。

每日总能量消耗基本上由基础代谢,身体活动和饮食诱导的热量产生组成。其中,基础代谢占全身的约60%,身体活动占30%,食物引起的产热占10%。因此,一旦基础代谢减慢,人体的能量消耗将大大减少。从长远来看,体内会积聚大量脂肪,此外,身体会变得不那么瘦。

男性和女性都在十几岁时达到顶峰,然后随着年龄的增长而继续下降。这是因为生长期三十多岁的青少年处于骨骼和肌肉的发育阶段,因此需要大量的能量,基础代谢也会增加。已经过成长期的成年人不需要太多能量来锻炼他们的骨骼和肌肉。因此,在20至30岁时,肌肉量将逐渐减少,基础代谢将减慢。

2.随着年龄的增长,基础代谢下降会发生什么变化?

The amount of metabolism is declining year by year. If you eat the same food as you were young, it will cause excessive calorie intake. And the more energy you eat will turn into fat and accumulate in the body. After the basal metabolism slows down, if we still keep the original diet, how much fat will it be?

Estimation of fat increase based on low basal metabolism:

?

Based on the 18-year-old basal metabolism, the same eating habits will continue. In simple calculations, men will accumulate 0.4 kg of fat in one year and women will accumulate 0.3 kg of fat. When this life continues until 30, men will gain 4 kg and women gain 3.4 kg. At the age of 40, men gained 7.2 kg and women gained 6.2 kg.

This calculation is to ensure the amount of food in the past. If you eat more than before, greedy, irregular diet, etc. it will be fatter. Therefore, do not want to continue to gain weight because the basal metabolism is slow, it is necessary to reduce the amount of food in a reasonable time. In addition, you should add more muscle exercises to increase the speed of basal metabolism and prevent the accumulation of fat by enhancing muscle vitality and improving blood circulation.
