Although low body fat is really sexy and attractive to many people, just like the actors in the movie, Sylvester Stallone even reduced his fat content to 3% in the movie. But I still don't recommend that you reduce your body fat rate to single digits. Although some people look as good as anatomy textbooks, there is evidence that extremely low body fat rate and professional slimming all the year round will increase your risk of the following diseases.
Increased risk of heart disease In a study published in the International Journal of Sports Physiology and Sports Performance on 20 13, the researchers found that the heart rate of bodybuilders who control their diet to achieve a body fat rate of 4.5% is 27 times lower than that of normal people. We all know that low blood pressure is healthy, but if it leads to bradycardia, the chances of arrhythmia and sudden cardiac death will increase greatly.
Becoming weak and prone to illness may be the least controversial of these seven hazards, because a lot of practical and scientific conclusions have come to the conclusion that for many people, when you consume less calories than the calories in your body fat content, you will become weak. This is not only because calories = energy, but also because long-term fat loss may lead to fatigue, increase cortisol secretion and affect immunity. We all know that cortisol secretion will increase compared with people with more abdominal fat. However, maintaining a slim figure will also cause more stress to some people, and it will also lead to an increase in cortisol secretion, which will also affect your mood.
It takes courage for everyone to get tired, because controlling diet for a long time will make you feel tired. Moreover, the serious drop in heat will lead to insufficient energy supply during exercise. In addition, when the fat is exhausted, the body will not have much energy storage. In some studies, it is found that bodybuilders not only lose strength and muscle mass in the first few months of competition, but also spend more than six months in the process of extreme fat loss to recover muscle loss.
The irony of reducing testosterone and fat is that if you become slimmer, the lower your body fat rate, the sexier you are and the less you want to have sex. Many people think this is an online joke, but it is not. Because in the research of bodybuilding, the testosterone of athletes dropped from 9.22 to 2.27ng/mL in the months before the competition, the main reason is that proper fat is closely related to the normal secretion of hormones.
The weather became very cold. We all know that one of the main functions of fat is to keep warm. The decrease of body fat rate will cause you not to have enough fat to cover your muscles, which will make you colder than others. Moreover, visceral fat plays an important role in helping to isolate and protect organs. For some people, when they drop to single digits, they will experience a feeling of being extremely cold to the bone.
Will die faster in famine.
Although this topic sounds a bit excessive, it must be said that the sports philosophy related to it is that the strong are more difficult to be killed than the weak and have stronger overall ability.
Crazy slimming may reduce your strength, resistance and endurance. Aesthetically, you may be the best one, but if you agree with what I said in this article, it's hard not to agree that keeping a very low body fat can't make you healthy.
So what is the most suitable body fat rate?
If there is no special demand, it is suggested that the body fat rate should be kept at 14- 17% for men and 2 1-24% for women.
