Why do boys have thinner legs than girls?

The season for showing legs is here. Although we see many girls with big legs when walking on the street, I don’t know if you have noticed that there seem to be more boys with thin legs than girls?

If we see a girl with slim legs, we will feast our eyes on her and praise her. But if we observe carefully, we will be suddenly alert. Many boys actually have slim calves, but they just hide them under strong sports pants. And it wasn’t until the hot summer arrived that I finally changed out of my shorts to keep cool and realized that boys’ legs are slimmer and more beautiful than most girls.……

Is this situation accidental? No, it is an innate decision-making process.

If you recall carefully, you will find that boys' legs are thinner than girls. This is not an isolated case, but an extremely common and high-probability event. Men do have an advantage over women in terms of "thin legs".

Men's bodies contain more androgens and women's bodies contain more estrogen, which have different effects on body fat and muscles.

When we are just born, everyone's body shape and fat distribution are not very different. However, as the body grows, the body's female hormones also begin to change significantly according to gender. Generally speaking, men's bodies have more androgens, while women's bodies have more estrogen, so they gradually develop different gender characteristics.

Although there are many types of androgens and estrogens, what is interesting is that many scientific studies have found through experiments: Generally speaking, an increase in androgens can lead to an increase in body weight and lean muscle, while an increase in estrogen can also lead to an increase in body weight, but unlike androgens, it mainly promotes the increase of water and fat.

Moreover, scientific research ultimately shows that these two types of estrogen may also have a certain impact on muscle appearance.

Therefore, generally speaking, for men and women of the same weight and the same height, the body fat rate of men is usually much smaller than that of women, which is determined by innate gender characteristics.

As we all know, the volume of muscle of the same weight is far lower than the volume of fat of the same weight. This is why many girls always complain that they look fatter than boys. After all, we have no advantage here innately.~

If you carefully observe the body shape characteristics of men and women, you will find out. When a boy starts to become obese, he seems to have more of a "big belly", but his legs are still not fat. How to gain weight? ； When women first become obese, they will have significant lower body obesity such as waist, abdomen, buttocks, and feet.

In fact, this is also caused by the different effects of estrogen on the metabolism of human adipose tissue:

1. Male hormones are more likely to cause central obesity

Although the distribution of body fat is closely related to some estrogen components, in general, androgen will cause the pre-fat tissue in the abdomen to convert into adipose tissue and continue to accumulate, preventing body fat from migrating to the feet, and finally causing central obesity, which is the "big belly" that is very common in men.

2. Estrogen causes lower body obesity

Estrogen helps promote the conversion of fat in the breast and subcutaneous tissue. When the body begins to accumulate unnecessary fat, estrogen will cause the fat tissue in the body to spread. Finally, it will gradually accumulate in the waist, buttocks and feet, especially the buttocks and thighs, thus forming the commonly referred to as "thick legs" and a "pear-shaped figure."

Seeing this, many women may be very dissatisfied - why are women more likely to gain weight, and the fat areas are still important parts such as buttocks and legs.

In fact, for women, it is very easy to develop obesity in the buttocks, abdomen and other parts. In addition to being affected by innate factors, it is actually indispensable for women to carry out good pregnancy and inheritance tasks. After all, only thicker fat accumulated in the waist, abdomen, buttocks and legs can provide abundant energy reserves for subsequent pregnancy, childbirth, etc.

In that case, does it mean that girls are always obese and cannot have a pair of beautiful legs? Of course not, although we are congenitally "worse" than men, we can still rush forward through acquired hard work! After all, there are so many girls with thin legs encouraging us. If we just "keep our mouths shut and open our legs", everyone can have big legs.
