Is a woman’s thin waist related to estrogen?

Indeed, according to research by American scientists, no matter how much a woman weighs, men like women with a waist circumference of 70 cm. In the eyes of men, women with thin waists can be called real beauties. . Why do men like women with thin waists? This is an inherent instinct, because waistline is one of the most easily identifiable signs of a woman's fertility and health. Over thousands of years of evolution, men naturally prefer women with strong fertility and health, while girls with thin waists are more fertile. This is because women with thin waists have higher estrogen. A girl may have a thick waist in childhood, but once she reaches puberty and after puberty, her estrogen secretion will be strong, her waist will become thinner, and her buttocks will become larger, so she will appear to have a thin waist and wide buttocks. After middle age, estrogen decreases and the waist circumference will gradually expand. This is why young girls have thin waists, but once they reach middle age, their waists bulge like buckets. Obesity means low estrogen, which also indicates a greater risk of disease. Just imagine, which man would have a soft spot for a woman with low fertility and illness? Of course, modern medicine can accurately identify women's fertility and health problems, but in ancient times, medicine was not developed, but British, American and Asian writers could intuitively know the biological connection between beauty and health. It can be said that a thin waist is the standard of beauty, which is almost determined by human instinct. Among all animals, in order to reproduce the population and inherit excellent genes, females always look for the strongest males to mate, and males also strive to find the healthiest females. This is consistent with Darwin's theory of evolution. And a woman with a thin waist will convey a valuable message to men, that is, such a woman is more likely to give birth to healthy offspring and can inherit the excellent genes of men, which will give men an instinctive attraction, so every Men of the era preferred women with thin waists, and thin waists have become the eternal standard for beauties.
