If you are fat, you are not tall. Higher body fat percentages increase hormone resistance to growth hormone.
Because of this, secreted growth hormones reduce the effect of causing growth. In other words, assuming that the same amount of growth hormone is secreted, children with obesity are more likely to be shorter than children of normal weight.
Along with this, obesity is a direct cause of precocious puberty.
Child obesity often has high levels of blood cholesterol and triglycerides, both of which stimulate the release of sex hormones, leading to early menarche and metamorphic periods, resulting in early closure of bone growth plates and shorter growth times. In particular, children with obesity often have a significant amount of exercise and lack of physical stimulus in the growth plate, and most of them eat fast foods or high-calorie foods with high sugar content.
This also additionally causes growth disorders.
After all, an obese child grows faster than a tortoise like the rabbits of rabbits and turtles, and eventually loses to the turtles.
