Weight Loss and Belly Slimming: Understanding Genetics and the Causes of Childhood Obesity for Scientific Fat Reduction

Heredity refers to the transmission of traits from parents or other parents to their offspring. From a genetic perspective, there are approximately 5 million "genes" within the nucleus of human cells. These not only directly influence the physical characteristics of offspring, such as appearance and physique, but also possess multifaceted heritability. Obesity also has heritability (Table 1-5). According to the research on body type inheritance by Comrade Liu Xianwu in my country, parental body type has a certain influence on the development of their children's body type. Foreign medical experts have conducted the following two studies, which are equally convincing.

Those with high metabolic rates gain less weight, while those with low metabolic rates gain more weight, with a difference of five times. Their experiments on infants revealed that babies born to obese women had a 24% lower basal metabolic rate than babies born to underweight women. When the quantity and quality of food consumed by both types of infants were roughly the same daily, the weight difference was significant after one year. The infants of obese women with low basal metabolic rates became obese, while the infants of underweight women with high basal metabolic rates had normal weight.

Example 2: Medical experts' research on identical twins found that when twins had essentially the same living conditions and environment after birth, if one was obese, the other would also be obese; if one was thin, the other would also be thin. The accuracy was as high as 80%. As adults, when the twins' living conditions and environments differed, the consistency of obesity and thinness decreased by only 30%.

Research by Comrade Liu Xianwu and foreign medical experts proves that while obesity has a certain heritability, postnatal plasticity is also very important. For example, by adjusting nutrition and engaging in scientific physical exercise, it is possible to control weight gain and achieve weight loss.

What are the causes of childhood obesity? First, a lack of scientific feeding knowledge. Some parents or elders lack scientific dietary and childcare knowledge, believing that letting children eat more, eat well, and sleep more is loving their children. To make their children chubby, parents go to great lengths to ensure they eat well, eat more, and sleep more, sometimes even resorting to force-feeding methods, such as chasing after them to feed them, leading to overeating and obesity.

According to a survey conducted in February 1991 by Beijing Children's Hospital on a winter camp for obese children, the campers' history of obesity was related to their diet. These obese children had good appetites from a young age, and their parents allowed them to eat whatever they wanted without any restrictions. These children loved snacks, sweets, and fried foods. Many campers also had a habit of binge eating and drinking; some ate 550 grams of noodles with soybean paste in one meal, some ate 35 skewers of lamb at once, some ate two roast chickens in one meal, and some ate 4 kilograms of sugar a month, etc.

Secondly, inappropriate parenting methods also played a role. Some parents were eager for their children to succeed, hoping they would study hard and avoid trouble; some parents promised their children food, bonuses, toys, etc., if they didn't make a fuss. Some parents, especially grandparents, are overly doting, loving their children but not in the right way. They believe that because their own childhood was difficult, lacking food and clothing, and now they have more income and are wealthy, and this is their only child, they indulge the child in everything, giving them whatever they want. Candy, pastries, various drinks, etc., are always given to them. This fosters a habit of snacking in children; they are overjoyed when they have food, and the more and better the food, the happier they are. Little do they know that the calories from the high sugar and high fat ingested from snacks cannot be burned off even with 2-3 hours of physical activity, inevitably leading to childhood obesity. These elders, rather than loving their children, are harming them.

Third, over-protection and lack of physical activity. Some parents rarely guide their children to participate in sports, and they also do all the daily chores for their children that they should be doing themselves, fostering bad habits such as laziness, gluttony, and aversion to activity from a young age.

Due to overeating, long sleep durations, and insufficient physical activity, over time, the calories consumed from food exceed the calories burned, causing the excess calories to be converted into fat and stored in the body. Therefore, childhood obesity is widespread.

The Harms of Obesity

Some say that being fat is "beautiful," which is true; the people of Tonga, a Pacific island nation, believe that being fat is beautiful and being thin is ugly. Some say that being fat is "healthy," which is also true; in the United States, there are diving competitions for obese people, where the competition doesn't consider technique, skill, or posture, but only who can create the largest splash. Others believe that being fat is "fashionable," thinking that fat people are cheerful, approachable, reliable, and trustworthy.

Regardless of how many admirable aspects there are to being fat, a comprehensive assessment by modern medicine across multiple disciplines reveals that the harmful effects of obesity remain paramount.
