What causes weight gain? Why do we gain weight?

Gaining weight is undoubtedly a very troublesome thing for people who love beauty. When we gain weight, we always try various ways to lose weight. So why don’t we figure out the reasons for gaining weight first? Let’s take a look at the reasons for gaining weight today!

What is the cause of obesity?

01. Improper diet: Many people like to eat junk food, such as fried food, puffed food, sweets, etc. These foods are high in calories and difficult to digest, which can easily lead to weight gain. Some people have irregular diets and like to overeat. Taking in too much food at once can also lead to obesity;

02. Genetic reasons: If the family or both parents are fat, the chance of children becoming obese will increase significantly, much higher than that of children from normal families.

03. Postpartum weight gain: Many women eat and drink a lot after giving birth and do not pay attention to controlling their body shape during the confinement period. This leads to weight gain and obesity. Their body shape is completely out of shape and their muscles become loose.

04. Lack of exercise: Many people don’t like to exercise and prefer to lie down after eating. They sit down when they get home from work every day and rarely exercise. Over time, this leads to the accumulation of fat in the body, which can also cause obesity.

05. Drugs: Many drugs contain hormones, which will cause changes in the body's metabolism during consumption, leading to weight gain and obesity. There are also various diet pills, but after taking them, the rebound effect is very fast, and the weight only increases and does not decrease;

06. Lack of sleep: Many people now have irregular work and rest schedules and like to stay up late and sleep late. This will damage the body's functions in the long run, leading to fat accumulation in the body, thus causing obesity;

07. Excessive mental stress: Nowadays, people live at a fast pace and face various pressures in life and work. When people are under great mental stress, they often turn grief and anger into appetite, eat and drink a lot to transfer and vent their stress, which leads to obesity. This situation is very common in life, because delicious food can relax people;

08. Bad habits: In life, we may sit down right after eating, or often cross our legs. If we persist in such habits, it is easy to cause fat accumulation in the stomach and legs, thus causing obesity.

09. Edema and puffiness: When there is too much water in the body and it cannot be discharged, it will cause edema, which will lead to puffiness. In this case, we should eat less salt and eat more diuretic foods, such as winter melon, bitter melon, watermelon, etc. This can accelerate the discharge of water in the body and relieve edema.

10. Poor metabolism: If you cannot digest food, the calories will accumulate in the body and cannot be metabolized, which can easily lead to obesity. When there is a problem with metabolism, many diseases such as high blood pressure, high blood lipids, high blood sugar, etc. will come to us, and weight will also increase. In addition, bad living and eating habits will also affect metabolism.

Obesity often starts from the abdomen

In fact, fat accumulation often starts from the abdomen, especially in middle-aged men, menopausal women, and women with endocrine disorders. Abdominal obesity is also called male-type obesity, which is related to excessive secretion of male hormones and a sharp decrease in estrogen in the body, as well as visceral obesity. The abdomen is the main concentration of the internal organs. It is not surprising that a diet that is too rich and a long-term high-calorie diet will cause visceral fat obesity and abdominal obesity.

How long does obesity last during puberty?

The time of gaining weight during adolescence varies from person to person. Some people who gain weight during adolescence will lose weight in adulthood, but there are also cases where the weight continues to increase. If you don't work hard to lose weight, your weight will not go down on its own. Regarding this question, whether you will lose weight after gaining weight during adolescence depends on different individual situations.

Morbid obesity

Diseases that cause pathological obesity may include hypothyroidism, increased cortisol, pituitary lesions, brain damage, insuloma, diabetes, etc.

The more fundamental reason is that the metabolism of these obese people is significantly different from that of people with normal weight. For example, the concentration of thyroid stimulating hormone in the blood of obese people decreases, and the basal metabolism is lower than that of normal people.

Under the same dietary conditions, fat people have lower food specific dynamics than thin people, but their anabolism is more hyperactive than normal people, which can make people gain weight. If there is a genetic defect, esterase disorder, or biochemical process disorder, people can gain weight even if there is no problem of excessive calories.

In addition, the material metabolism and endocrine functions of obese people are also different from those of normal people. For example, the fasting free fatty acid concentration of obese people increases, and the triglyceride and cholesterol content increases, which leads to fat metabolism disorder, decreased growth hormone secretion, and reduced fat mobilization in obese people.

High insulin levels induce hypoglycemia, increase hunger, and eating more leads to obesity, forming a vicious cycle; adrenal cortex hyperfunction increases the excretion of urinary 17-hydroxycortisol, forming typical central obesity. The hypothalamus in the brain has an appetite center (producing hunger) and a satiety center (producing a feeling of fullness).
