When weigh the weight, the value increases again when the waist is measured. Except for the annoyance or discouragement, the question that most of my heart rethinks is: How is it fat (and fat)?
Knowing the reasons for getting fat, and fundamentally controlling, it is possible to "kill in the cradle"! The causes of obesity are very complicated, and science has developed to this day, and it has not yet been fully clarified. But the consensus is that because long-term energy intake exceeds the required amount.
However, there are many related factors that are also worth noting.
genetic factors:
Genetic factors are the most helpless factors. There is no way to change the inheritance, so if you spread the genetic factors of obesity, you will only pay more attention to yourself!
The survey found that 60-80% of severe obesity has a family history. If both parents are fat, the probability of obesity in the next generation is 87%, and the lowest is 63%. If only one parent is fat, the incidence of obesity in the next generation is 38%-51%. This ratio is really impressive!
Of course, even if there is a family history of obesity, gaining weight is not necessarily a genetic factor. If you are fat, there is no reason to push your responsibilities to your parents. Philosophically, internal factors need to be influenced by external factors.
Nervous system factors:
The factors of the nervous system are too complicated to describe, and there is no need to elaborate. There are several hypotheses, including the theory of overeating; the theory of autonomic causes; the theory of enhanced absorption of glucose in the small intestine, and so on, and in general, the mechanism of hypothalamic injurious obesity. Because clinically, patients with meningitis or sequelae often show a large amount of food and obesity, and their lesions may be in the hypothalamus, so this study was triggered. The effect is that the reaction of the hypothalamic satiety center is slow or weak, resulting in loss of fat metabolism, increased body fat, and obvious obesity.
There are also views that these may also be caused by abnormalities in the central nervous system.
Therefore, fat may also be due to illness, not just too much to eat too much, it is necessary to check medically to avoid risks other than "abdominal".
Mental and psychological factors:
Mental or emotional problems may also be the cause of obesity. Frustrated for various reasons, mentally motivated, emotionally unstable (such as sadness, anxiety, depression, and even a feeling of being abandoned), or due to fatigue, or to avoid some difficult problems in real life Avoiding certain tensions and so on may prompt us to take compensatory eating and relieve psychological stress and discomfort. This is reflected in the film and television works! It is often seen on TV or in movies that when a girl is in pain, she eats and eats it to vent her emotions. In fact, men are the same, depressed about a group of friends drinking risotto, the same is to ease the psychological pressure.
Of course, the same mental stress is also experienced, and people with different types of neurological activities will behave differently. Some people show that adrenaline can be stimulated or sympathetically excited, so the appetite is inhibited, the tea does not think about rice, and the belt gradually loses weight. The other type of person, the performance of the vagus nerve excitement, increased insulin secretion, appetite hyperthy, the more nervous the more you eat, the "blessing".
Biochemical aspects of enzymes in the body:
One of the things that makes us most annoyed is that some people eat a lot, but they can keep their bodies; and they may belong to that kind of food, and they don't eat much, but they are easy to grow meat. We often say that "drinking cold water and long meat" is an exaggeration of this phenomenon.
As far as the current research is concerned, we know that this is because the amount and activity of sodium/potassium adenosine triphosphatase (Na+K+-ATPase) and lipoproteinase (clearing factor lipase) are different in each human body. The amount and activity of these two important enzymes that regulate and maintain weight, if unfortunately low, then the amount of food you eat into heat is only half that of lucky people. This of course will gain weight!
In addition, there are other biochemical factors such as the fatty acyl-CoA enzyme and the metabolism of ATP (a high-energy bond compound). The mechanism is too complicated, so I will not say it to everyone.
The most easily understood but equally difficult dietary factors:
Regardless of the number of other factors, the most direct cause of obesity is due to excessive energy intake; or too little consumption; or both excessive intake and low consumption.
When I was a child (in the early 1970s), obesity was considered a "rich disease." At that time, I heard that developed countries and wealthy and qualified people had hopeful obesity. But nowadays, obesity has become a "poverty disease". People in developed countries have a good life. They have the time to have money and exercise. The people who have just developed the country can finally let go of eating and drinking, and not so strong. Consciousness, so it quickly became fat.
Eating is both an important pleasure in life and a necessary social activity. Therefore, it is often eaten more than the actual needs of the body. Excessive intake is a non-negligible dietary factor that leads to obesity.
In addition, eating habits and dietary structure also have a great impact on obesity. The same food, when it is early or night snacks, the effect on weight is completely different! Because the body's excitability and insulin secretion in the evening is higher than in the daytime, and the activity in the evening will be less, it is more conducive to the accumulation of fat in the body. But for modern people, they have to rush to work in the morning, usually at the noon, and only have time and conditions to eat at night, which is inevitably easy to gain weight.
There are also times of eating, people with fewer meals are more likely to gain weight than people with more meals, because more meals can not only reduce the accumulation of fat, but also help us control appetite. Hungry for a long time, it is inevitable that I will not eat a few more mouthfuls, and hungry and hold back not to eat, how much torture is the spirit!
Needless to say the dietary structure, big fish and big meat will naturally grow fatter than radish cabbage.
Sports consumption factors as important as diet:
The amount of physical exercise determines the amount of energy consumed by the body. Increasing the amount of activity is also the most powerful "weapon" to suppress fat accumulation. It is obvious common sense that the amount of activity consumes a lot of energy and the chance of obesity is small.
It is important to mention that different types of exercise have different effects on body fat content, and aerobic exercise is most effective in reducing body fat. This may be because aerobic exercise can affect the function of the nervous and endocrine systems and increase the activity of multiple enzymes of lipid metabolism.
Anaerobic exercise can also increase the body's energy consumption, but the weight loss effect will be worse. Compared with weightlifters, weightlifters have a much larger muscle mass, but it is definitely a much lower percentage of body fat and body fat in long-distance runners. There are also world brawny games, the strength of the Hercules is amazing, can move the barrel to push the big stone, but the "big waist" is not a very low body shape, which shows that the simple strengthening of strength exercises, fat reduction effect is not very obvious.
Therefore, in the exercise and fitness must arrange some aerobic exercise, which can be jogging, brisk walking (speed is greater than 115-125 steps per minute), swimming, climbing, Tai Chi, various aerobics and so on.
