Studies have shown that in 2020, the problem of overweight and obesity among Chinese residents continues to be prominent, more than half of the adult residents are overweight or obese, and the overweight obesity rate of adolescents aged 6-17 and children under 6 years old reached 19% and 10.4% respectively.
Obesity can not only lead to dyslipidemia, abnormal glucose metabolism, increase the risk of cancer, and even affect the reproductive function of men and women.
Gaining weight does not happen suddenly, in fact, when you gain weight, the body will produce premonitions. Let's take a look.
Is there a premonition to getting fat?
At present, the most commonly used tool in the world to measure obesity is the body mass index (BMI). The formula for calculation: Body mass index (BMI) = body weight (kg) / square (m) of height. Chinese standard: 24> BMI≥ 18.5 kg/ m is normal weight, 28> BMI≥ 24 kg / m is overweight, BMI ≥ 28 kg / m is obese.
Before getting fat, the body sends out some signals:
1. Dull taste, eat more and more
The taste buds can perceive the sweet, sour, bitter, salty, and fresh food, while stimulating the reward center of the brain, making people feel satisfied and happy after eating the food. When the body's fat gradually accumulates, the taste buds become sluggish, and the food is not as fragrant as before, a vicious circle of overeating will be formed.
2. Drowsiness, dizziness and headache
Studies have shown that more than 40% of obese people suffer from obstructive sleep apnea hypopnea syndrome, especially those with obese necks, sleeping snoring, repeated awakenings, and lack of oxygen at night lead to a decrease in sleep quality. When I wake up the next day, I often feel headaches, dizziness, drowsiness during the day, inability to concentrate, and memory loss.
3. Thin belly and thighs, weak limbs
The habit of eating too much can lead to abdominal obesity, that is, fat accumulates under the skin and internal organs of the abdomen, which is one of the reasons why many people form an "apple-shaped" body with thin belly and thighs. As fat increases, outdoor exercise decreases, vitamin D levels decline rapidly, and the risk of osteoporosis increases dramatically in obese people, especially men.
Does gaining weight affect fertility?
On average, 1 in 7 infertile couples is associated with obesity, and for every 1 kg/m increase in BMI, pregnancy rates decrease by 4%.
Studies have shown that losing 5% to 15% or more of weight over a 6-month period can improve ovulation and menstrual conditions in women, and men can improve less weak spermatozoa and improve sexual function.
female:
Overweight women have 8% lower fertility, obese women have fallen by up to 18%, and the higher the BMI, the greater the age of conception. Obesity affects a woman's natural conception and can also reduce the success rate of IVF.
Not only that, the incidence of complications such as hyperhydramnios, preeclampsia, placental abruption, and gestational diabetes will increase by more than 2 times in obese women before pregnancy.
In addition, the risk of neural tube malformations, attention deficits and hyperactivity disorders in offspring increases by more than 1-fold, and the risk of obesity in offspring increases by 7-10 times.
man:
Obesity also significantly increases the incidence of male infertility, when extreme obesity (BMI>40 kg/m), the number of sperm decreased significantly, the incidence of morphological abnormalities increased significantly, and the incidence of azoospermia rose to 9.1%.
What are the dangers of getting fat?
Being overweight or obese can increase the risk of developing a variety of chronic diseases, such as coronary heart disease, heart failure, high blood pressure, and type 2 diabetes.
In addition to this, obesity increases people's risk of cancer.
A 2017 study showed that nearly one-third of the world's diagnosed new-onset cancer patients were due to abdominal obesity.
In addition, sedentary people have a 40 percent higher risk of colon cancer than people who exercise regularly.
Life is in motion,
Sitting for a long time will definitely hurt the body,
Friends, get up and move!
