The body changes over time

Normally, the human body will change from year to year. If you know the basics of this change and take measures to prevent aging, your body will greatly improve and reduce the signs of aging.

Does the body shape change over time?

Do not feel that your body is changing when you get older?

The fact that each body will change more or less over time, the older the body, the easier it will become. This can be interpreted based on a reduced amount of basic metabolites, so even if you keep the same exercise regime, the calorie consumption will be less. However, if you still keep the level and eating habits as before, the balance between digestibility and calorie consumption will be affected. Your body changes more or less based on age and gender. See the following trend of change given for a quick, timely improvement.

The older you are, the easier it is to gain weight

Analysis showed that the total energy consumption per day of metabolism tends to decrease with age.

The basic metabolic ability is the energy needed for each person’s body to maintain functional functions such as regulating heart rate, breathing, controlling body temperature. Even when you sleep, these energies are still consumed.

This basic metabolism is consumed continuously 24 hours a day and accounts for more than 70% of the total energy consumption of the whole day.

Age changes basic metabolic rate

For the body with good metabolic ability, it will lead to the ability to easily lose weight and difficult to gain weight (by large energy consumption).

After the body grows, the aging process begins to take place slowly, the cycle of cell regeneration slows, the amount of muscle needs to consume more energy.

Will fat accumulate around the abdomen according to the aging process?

Please refer to the picture below to get details.

This is a graph that shows “What percentage of body fat accounts for when total body fat is 100” by the age of 35 to 80. Fat distribution can be easily seen (including fat). organs) of both men and women increased rapidly with age.

The largest amount of fat accumulates in the abdomen. When over 50 years of age, in men, more than 60% of total body fat is accumulated in the abdomen. As for women, when they are over 30, the amount of fat in the abdomen accounts for more than 50% of the body fat. People of certain ages are more likely to increase fat distribution in the abdomen, even if the percentage of body fat is not too high, especially visceral fat tends to increase.

Besides, when belly fat and visceral fat increase, blood fat and blood pressure tend to be higher and the level of metabolism increases accordingly. There are statistics showing that this will have a significant effect on liver function. People 30 years of age or older also need to be cautious even if the body fat percentage of the entire body is not high. Therefore, reducing abdominal fat is not only for improving appearance but also for health. 1) 2)

The level of aging in men and women is different

The common point in the aging process in both men and women is that the amount of fat in the abdomen is increasing, and the metabolic ability is also affected. However, in terms of physique changes, the changes in body composition, as well as the amount of fat distributed in the body of the eyebrow and women, have many differences.

For men: The amount of muscle in the arms and legs decreases
There is no denying that, when men reach the age of aging, the amount of belly fat will increase much. However, this is not worrisome because the amount of muscle will gradually decrease significantly.

Initially, the amount of muscle in men is larger than that of women, although the fat percentage is lower. In men, muscle mass will gradually decrease with aging of the body. Especially the trend is clearly shown in the arms and legs. According to statistics, when men enter the age of aging, muscle mass in arms and legs will decrease.

For this reason, over time, men’s muscle mass gradually decreases due to aging, so even if their weight is not too much, the fat ratio (body fat ratio) often increases.

For women: The amount of fat on the upper body tends to increase

Women are more affected by visceral fat than muscle mass and tend to change significantly more than men.

Please refer to figure 4. When under the age of 30, the percentage of women’s body and arm fat is less, and the percentage of fat of the legs (including buttocks) is distributed. more. Young women often have less fat on the upper part of the body like the arms, the abdomen, the lower body such as the thighs and the buttocks, are fat. However, after the age of 30, the percentage of body and body fat increases gradually, and at the age of 50, the amount of fat will be evenly distributed in the female body.

In other words, for young girls, fat tends to allocate in the upper body like arms and abdomen. When you are over 50 years old, the amount of fat will be evenly distributed over the woman’s body and make her body become fatter.

What is a youthful body?

If you wonder “Which shape helps you look younger?”, You can find the answer by comparing the physique of today’s young generations.

◎ Male: Although the body fat percentage is low, the body mass is large and thick, especially in the arms and legs, the belly is slim and low in fat.

◎ Women: slim waist, slender arms, thin and delicate shoulders; The amount of fat distributes many thigh areas

If shown by the image, you can refer to figure 5. Young people tend to be “more rounded”, and can also see muscle mass, as well as the distribution of fat between men and women, have huge differences.

Ways to maintain fat consumption regardless of age

So how can we maintain body weight, body fat, muscle mass as young as possible without reducing the age-related metabolic rate? If you are aware of the underlying metabolic rate decreasing year by year and taking action to reduce energy (calories), you can prevent excess energy, but be cautious.

If we only “reduce our diet” without paying attention to nutritional balance, the amount of protein that produces muscle and the amount of vitamins & minerals that promote the basic metabolism also decreases. Therefore, it is necessary to reduce the amount of food reasonably so as not to fall into a vicious cycle that is harmful to health.

To do this, you need to “add more vitamins and minerals even though they have low-calorie levels, but will contribute to muscle production and promote basic metabolic rate.”
Specifically, refer to the following mentioned contents. To capture the basic metabolism, it is recommended to measure it with a body composition analyzer. This helps you understand “how easy your body is to consume”, the amount of body fat that is maintained “in the” basic metabolic assessment “.

However, it should be noted that the body weight decreases, so the basic metabolic rate should be maintained, but now also reduced, so we cannot see the changes in the exchange rate. basic substance.

Try exercising/implementing the diet according to the instructions.
