Causes of obesity and ways to lose weight With the continuous improvement of living standards, more and more people are beginning to be troubled by obesity. Obesity can occur in any population at any age and is a very common phenomenon in daily life. Let's look at the causes of obesity and ways to lose weight.

Causes of obesity and methods of losing weight 1 1. The main cause of obesity is genetic factors.

Heredity is a very important cause of obesity. All children's genes are directly inherited from their parents. If either parent carries the obesity gene, or both parents carry the obesity gene, then a large number of children will have obesity problems at birth.

Second, the main causes of obesity are influenced by social and environmental factors.

People often think that eating is a blessing, and they have always advocated the people's awareness that food is the sky. Therefore, when they see something delicious in their lives, they will eat it as soon as possible, and they will not pay special attention to the problem of excessive calories. With the continuous improvement of living conditions, all kinds of delicious food tempt us all the time. If you don't pay attention to controlling your food intake in your daily life, it will easily lead to obesity.

Third, psychological factors affect the main causes of obesity.

Seeing this, you may have questions. Can this psychological factor also be the cause of obesity? The answer is yes, many people will calm their mood and vent their pressure by eating and drinking when they are bored and in a bad mood. If you overeat for a long time, resulting in excessive calorie intake, obesity will naturally come to you.

Fourth, the main cause of obesity is the influence of too little exercise.

Exercise can help the digestive tract in the body absorb and digest food, which is very helpful for fat consumption. With the continuous progress of science and technology, people have cars instead of walking, elevators up and down, less and less exercise, and the problem of obesity is becoming increasingly prominent.

Healthy weight loss must follow a general principle, that is, slow and steady, and nutrition is not reduced. First of all, the main causes of obesity are unreasonable eating habits, schedule and a small amount of exercise. Therefore, if you want to lose weight, you have to start from these aspects.

First, work and rest should be regular. Developing a good routine is not only beneficial to the health, but also plays a certain role in losing weight. For some young people, habitual staying up late has almost become a part of life. In fact, bad work and rest can easily cause a series of bad symptoms such as insomnia, forgetfulness, anxiety and decreased immunity. Besides, many people like to eat supper at night. Studies have shown that it is easy to get fat after eating at 9 pm.

Second, develop good eating habits. Generally speaking, obese people prefer meat and oily food, which is high in calories and easy to form fat, which is easy to cause unbalanced nutrition and affect their health. Therefore, in order to be healthy, we must develop good eating habits. First of all, eat regularly, don't overeat, and eat three meals a day on time to ensure balanced and comprehensive nutrition. When eating, we should also pay attention to some small details, such as drinking soup before eating (soup first, no prescription), not eating too fast, learning to chew slowly and so on. These can all play a role in losing weight to a certain extent.

Third, moderate exercise is very important for healthy weight loss. Life lies in exercise. Moderate exercise can not only lose weight, but also enhance physical fitness and be beneficial to health. Exercise is the king of health. According to experts, exercising for half an hour every day can enhance people's happiness index. But for dieters, it is only necessary to increase the amount of exercise and time at the beginning of exercise. If the amount of exercise is too large, it will rebound badly as soon as it stops, but it is good to get into the habit slowly. Exercise to lose weight is one of our most direct and effective ways to lose weight.

Causes of obesity and ways to lose weight 2 What are the causes of obesity?

Body fat caused by genetic factors

Not all people get fat the day after tomorrow, but there are also congenital reasons. One thing we can't deny is that genetic factors can also affect obesity. People's metabolic speed is different, which is a normal individual physiological difference. It doesn't mean that a lower metabolic rate will definitely make people obese. Just as everyone's genes contain oncogenes, not everyone will get cancer and grow tumors. Some people are born obese, but there must be inducing factors. Heredity affects brain function, and heredity determines a person's weight level, hunger level, saturated ascites level and metabolic rate, but it is not the direct leading factor of obesity.

Body fat caused by toxin

If we don't eliminate the garbage and toxins in our bodies, we will have the effect of obesity in our bodies over time. Toxin is a broad concept. When individuals can't decompose, utilize or excrete, all natural or synthetic substances (the vast majority) are called toxins. Some substances are beneficial to the first individual, but they are not beneficial or even harmful to the second individual. At this point, the substance is a toxin to the second individual.

When I was young, I liked to eat greasy food, which made me fatter.

Now living conditions have improved a lot, and our diet has also changed a lot. Diet is the main cause of obesity. When I was a child, many people liked to eat greasy food, such as fried chicken legs, fried chicken wings and potato chips. These foods are very delicious, but eating too much will lead to obesity.

Obesity caused by work stress

With the accelerated pace of life and the increasing pressure of work, many office workers will feel nervous. Stress can stimulate appetite and inhibit digestion, and overeating has become the norm. It is easy to cause abdominal fat to accumulate continuously, leading to weight gain.

Poor sleep quality leads to obesity.

Sleep can regulate the body, eliminate fatigue and promote the normal nervous system. Of course, this is on the premise of adequate sleep time. Insufficient sleep time will cause physical problems.

Adequate sleep can secrete more hormones and help the body to convert fat into energy. The deterioration of sleep quality will hinder this transformation process, leading to metabolic disorder, hormone secretion can not maintain the transformation of fat, which will lead to the storage of fat in the body, thus forming obesity.

A healthy way to lose weight.

Avoid losing weight quickly.

Losing weight quickly is what every woman pursues, but this eagerness for success will only make you fall into the crisis of slimming and rebounding. Only by losing weight healthily can we stay slim forever. It is true that excessive dieting and excessive exercise will make you lose weight quickly, but in the long run, it will be a very difficult road, and you will return to your previous habits because you can't stick to it. Then, naturally, I gained weight again. Only slow weight loss can bring you health and gentleness.

Control total calorie intake

Eating more does not mean eating more calories, just as 200 grams of boiled vegetables may not have more calories than 100 grams of cake. Some foods can not only increase satiety, but also contain lower calories, which is of great help to reduce calorie intake, while fresh fruits and vegetables are ideal diet foods. Some junk food or desserts contain higher calories. Therefore, if you want to lose weight, you'd better take healthy fruits and vegetables as the main part of your diet!

Adhere to a balanced diet

Remember to adhere to the principle of a balanced diet, including eating at least 5 servings of fruits and vegetables every day, and then ensuring proper intake of protein, carbohydrates, fat, etc. A balanced diet is not only the key to a healthy life, but also helps you to stabilize your metabolism and blood sugar level, which is very beneficial to healthy weight loss.

Try to eat less afternoon tea.

As for those tempting afternoon refreshments, please ask your family to cooperate with each other for health, and change from regular to occasional, and only eat 1-2 times a month to relieve your thirst. The rest of the time, we will eat healthier low-temperature roasted nuts without seasoning, low-fat milk, low-sugar fruits and so on.

You must eat starch.

Many people often equate carbohydrates with starch, but they are not the same. Carbohydrate refers to all substances composed of carbon, hydrogen and oxygen. Among them, fructose, lactose, glucose and other simple carbohydrates are most easily broken down by the body to provide energy quickly. Starch is a complex carbohydrate, which must be slowly digested and decomposed by enzymes in saliva and stomach before it can be gradually released into the blood and transformed into nutrients. Because of this, the satiety gained by eating starch will last longer than eating sugar.

Limit the intake of high-fat foods

One gram of fat contains twice as many calories as protein or carbohydrates, so now high-fat foods can help you reduce the accumulation of calories in your body, which is one of the most effective ways to lose weight. Eating less meat, eating more fruits and vegetables and avoiding fried foods can help you reduce your calorie intake.

Stop the yo-yo diet

The "yo-yo" reaction has been experienced by many dieters, and it is also a phenomenon that excessive dieting leads to weight rebound. Losing weight is actually a process of changing living habits, and it can't be completed in a day or two. Therefore, the best way is to eat healthily and exercise moderately. Excessive dieting will not only be harmful to health, but also lead to overeating!

How to control diet and lose weight

Fill yourself up with a little healthy oil.

Oil will slow down digestion, so adding a small amount of oil to your diet can make you feel full. But it is best to choose unsaturated oils, such as vegetable oil and dried fruit. If you want to control the heat, you should be careful about the amount of oil you use. Add a little olive oil to the bread and some dried fruit to the salad.

Have a purposeful meal

Don't eat in places that are easy to distract, such as TV. It's best to sit down and enjoy the food. Eat slowly, put down your knife and fork from time to time, and feel full. Eat consciously and leave the table when you are full.

pick fruit

A glass of juice contains vitamins, minerals and other phytochemicals, but if you want to lose weight, you'd better eat the whole fruit. Fresh fruit contains more fiber and less calories. For example, an average-sized orange contains 62 calories and 3 grams of fiber, and a glass of 200 ml orange juice contains 120 calories without fiber.

Causes of obesity and ways to lose weight 3. 1. Obesity is caused by the disorder of fat metabolism caused by internal factors of human body.

1, genetic factors

The occurrence of human simple obesity has a certain genetic background. According to the research report, if one parent is obese, the obesity rate of his children is about 50%; Both parents are obese, and the obesity rate of children has risen to 80%.

It is generally believed that human obesity belongs to polygenic inheritance and plays an easy role in its pathogenesis. The formation of obesity is still related to the interaction of lifestyle, eating behavior, hobbies, insulin response and social and psychological factors.

2, neuropsychiatric factors

It is known that humans and many animals have two pairs of hypothalamus related to feeding behavior.

3, hyperinsulinemia

In recent years, hyperinsulinemia plays an important role in the pathogenesis of obesity. Obesity often coexists with hyperinsulinemia, but it is generally believed that hyperinsulinemia leads to obesity, and the insulin release of obese people with hyperinsulinemia is about three times that of normal people.

Insulin can significantly promote fat accumulation. Some people think that insulin can be used as an index of total fat mass, and in a sense, it can be used as a monitoring factor of obesity. Some people think that plasma insulin concentration is positively correlated with total fat.

4. Abnormal brown adipose tissue

Brown adipose tissue is a kind of adipose tissue discovered in recent years, which corresponds to white adipose tissue mainly distributed under the skin and around internal organs. The distribution of brown adipose tissue is limited, only around the mediastinum and kidney in the armpit of the neck and the back of the scapula. The appearance of brown adipose tissue is light brown, and the cell volume changes relatively little.

5. Others

Eating too much can stimulate the small intestine to produce too many gastric inhibitory peptides (GIP) and stimulate islet β cells to release insulin. A special type of obesity can occur when pituitary gland is hypofunction, especially when gonadism and hypothyroidism are caused by the decrease of growth hormone, gonadotropin and thyrotropin. It may be related to the decrease of fat mobilization and the relative increase of synthesis. Obesity is mostly in women, especially in multiparas, menopausal women or those who take oral contraceptives, suggesting that estrogen is related to fat anabolism. When adrenal cortex is hyperfunctional, the increase of cortisol secretion promotes glycogen heterogenesis and stimulates insulin secretion, so fat synthesis increases, while cortisol promotes fat decomposition.

Second, the external cause is too much diet and too little activity.

When the calorie intake exceeds the required energy consumption, except for glycogen storage in liver muscles, almost all of it is converted into fat and stored in the whole body fat bank. Among them, triglycerides are the main ones. Due to the limited storage of glycogen, fat is the main storage form of human thermal energy. For example, eating too much neutral fat and sugar will accelerate the synthesis of fat and become the external cause of obesity. Obesity often occurs when there is too little activity, such as stopping physical exercise to reduce physical labor, or staying in bed during illness recovery and postpartum rest.

1. What eating habits are the causes of obesity?

Although obesity is caused by many factors, for simple obesity, dietary factors, especially bad eating habits, are the main reasons. This mainly includes:

Eat quickly.

Most obese people have a good appetite and eat quickly, so they gorge themselves. They can't be turned into chyme and coated on the stomach wall, so they often feel hungry after eating a lot. At the same time, because the chewing time is too short, the vagus nerve is still in an overexcited state, which causes hyperalgesia. In addition, because the blood sugar concentration rises after eating too fast, when the appetite center of the brain outputs the signal to stop eating, it often has eaten too much.

Snacks keep coming.

Some obese people, especially obese children and young women, seem to eat very little, but they have been eating snacks, resulting in excessive total calories accumulated in their bodies.

Don't eat breakfast.

Many women adopt the "hunger diet" in an attempt to lose weight by eating less or even skipping breakfast, but the result is counterproductive, even counterproductive. Because skipping breakfast will enhance the feeling of fasting in lunch, thus promoting the absorption of food, and a rich lunch will soon be absorbed, forming fat, which will lead to obesity over time.

An inappropriate dinner.

Because of the time, many people are used to eating simple breakfast and Chinese food When they are reunited with their families at night, they have plenty of time, so chickens, fish, meat, eggs and vegetables are all over the table. This arrangement is unscientific. Because after food is digested in the body, some of it enters the blood to form blood lipids, and at night, the insulin content in the blood rises to the peak of the day. Insulin can turn blood sugar into fat and condense on the blood vessel wall and abdominal wall. As time goes on, people become obese.

Eating too much sugar

Sugar is not only easy to absorb, but also can enhance the activity of enzymes needed to promote fat production and stimulate the secretion of insulin that can promote fat synthesis, thus making fat accumulate.

partial eclipse

Partial eclipse will lead to imbalance of nutrient intake and deficiency of some nutrient elements. As far as we know, lack of vitamin B can lead to obesity. Because vitamin B can convert fat into energy, B vitamins involved in fat metabolism mainly include B 1, B2, B6, etc. These vitamins mainly exist in brown rice, wheat bran and many fresh fruits and vegetables.
