"Heavy bones": reality or fiction?

 
23 March 2017, 09:00

Faced with the problem of excess weight, many people justify their pounds by the fact that they have "heavy bones". Scientists have conducted an experiment to find out whether this fact can take place, or it is just an "excuse", in order not to engage in themselves.

In a normal healthy person, the bone apparatus has a weight of approximately 8.5% of the total weight. That is, if a woman weighs 75 kg, then the proportion of the bone system will be only 7 kg. Of course, such a figure is unlikely to be significant for the overall weight index. Therefore, to write off the extra kilograms on the weight of bones, at least, is illogical.

It is established that the weight of bones directly depends not only on their magnitude, but also on the density. At the same time, the bone apparatus of women is initially easier than that of men. Of course, such factors as the motor activity of a person, his features of genetics, also have an influence. But these factors can change the mass of the bone system by no more than 10%, and this in total - no more than 1 kg to the total body weight.

Most recently, medical specialists from Canada conducted a study and determined for what reasons the human bones may differ in density.

An experiment was conducted to observe young people aged 14-16. Physicians surveyed and interviewed more than three hundred teenagers, primarily to determine the intensity of physical activity during the active development of the musculoskeletal system.

According to the results obtained, experts determined that those people who at least were moderately doing physical exercises in youth had a greater bone density later than those who were not physically active.

As pointed out by scientists, the density of bone mass in young people in recent years is constantly decreasing. This is due to the fact that adolescents pay little attention to physical activity, engaging mainly in computers, mobile phones and all kinds of gadgets. Therefore, the physical state began to gradually recede into the background. Presumably, the hour is not far off when medical specialists will begin to sound the alarm about the physical health of the younger generation.

Of course, it is very important to ensure normal bone density even in childhood and adolescence. After all, over the years, any person loses their bone mass. Bones are thinned for natural reasons, and in medicine this is called osteopenia. As a person grows old, the risk of fractures increases: the bone mass loses calcium and other minerals, becomes less heavy, less dense and more porous.

What can I do to improve the quality of my bones? Experts recommend: exercise, take calcium and vitamin D courses , walk more often outdoors (especially in sunny weather). If you follow the suggested recommendations, the bones will actually become "heavier" - but this is unlikely to cause excess weight: the body weight of a person depends mainly on the amount of fat and muscle tissue in the body.

The imposition of an adjustable gastric band that reduces the amount of food consumed - gastric banding - helps to reduce body weight and refers to restrictive (restrictive) methods that are used in the surgical treatment of obesity.

Endocrinologists diagnose abdominal obesity, when accumulation of excess fat tissue is concentrated in the abdominal and abdominal areas.

At different times, there were different standards for the aesthetics of the body. I recall the naked bodies of women in the paintings of Rubens - pompous beauties with carefully traced cellulite. 

The latest research relating "Heavy bones": reality or fiction?

A new drug that can save a person from excessive fat deposits, is created on the basis of chili pepper. The first tests have already demonstrated excellent results: it is true that experiments were conducted only on rodents.

Regular overeating in obese people is associated with less satisfaction from eating. That is, people get less pleasure in consuming food - as a consequence, they begin to consume it in larger quantities.
