Have you lost too much weight? If your body fat is too low, beware of early aging

The models in women's magazines all have long arms and legs and a slim and slender figure. Especially now that society's definition of a "good figure" is much lower than the standard weight, Japanese women, who have a strong desire to lose weight, will do anything to lose weight.

From a doctor's perspective, the so-called "standard weight" is the ideal weight set for a healthy life. The correct calculation method is "height (meters) × height (meters) × 22".

Taking a person who is 160 cm tall as an example, 1.6×1.6×22=56.32 kg. For those who aspire to have a model's figure, they must think that this weight number is too high, right?

Women's magazines produce weight loss specials all year round, constantly advocating that "thinness" is the standard of beauty. I can understand girls wanting to become thinner and prettier, but I have to question the idea of ​​over-praising skinny bodies. Have you ever heard of someone who lost so much weight that they no longer have their period? This is because body shape affects hormone balance. This is not some urban legend or something I just said, but a fact based on medical evidence.

Estrogen is not only secreted by the ovaries, but also by the body's fat cells. Taking a person of normal weight as an example, about 40% of estrogen is secreted by the body's fat cells. In other words, people with a slim body and fewer fat cells secrete less estrogen than those with more fat cells.

Women who have gone beyond being slim and are now simply "skinny" are more likely to experience physiological discomfort due to their low body fat. This is because fewer fat cells lead to less estrogen secretion, making it difficult to maintain hormonal balance.

If your weight is 20% lighter than the ideal weight, you will not be able to ovulate successfully, resulting in irregular menstrual periods. You may have heard that top female athletes, such as long-distance marathon runners or gymnasts, have extremely low body fat percentages due to extensive exercise and also suffer from physiological irregularities.

In addition, people who are much thinner than the standard weight will have their skin become less elastic and fine lines on their faces become more obvious when they reach 30 or 40 years old. The skin of a plump woman is usually smoother and more delicate than that of a thin woman.

However, don't think that being fat is okay. People who are overweight may also experience menstrual irregularities. If too much estrogen is secreted by fat cells, it will of course cause hormonal imbalance.

I once appeared on a TV show with several female artists who were quite plump. They suddenly gained weight due to overeating. When I asked them, “Are your menstrual periods still normal?” someone answered, “Not really… I only have my period about once every three months.”

Some overweight people have infrequent menstrual periods, also due to hormonal imbalance. Some people have even become so accustomed to having irregular periods that they don’t even notice they’re pregnant.

If the secretion of female hormones is insufficient, there is a high possibility of premature aging and calcium loss. There are a lot of rumors and incredible information about female hormones. Everyone believes in the wrong information but does not understand its original function and correct knowledge.

Whether body fat is too high or too low, it can lead to hormonal imbalance. "Amenorrhea" or "irregular menstruation" is one of the most important messages from the body. Please do not ignore it and be sure to actively seek medical treatment from a doctor.
