Many people think that obesity is caused by their own bad eating habits, belongs to personal reasons, so if they do not care, it will not have any impact on others, so they do not have the desire to lose weight. But the fact is not so, many studies have shown that genetics is also an important factor leading to obesity, when both parents are obese, the probability of obesity in children will increase a lot. Moreover, the medical science has now regarded heredity as an important cause of obesity. Modern genetics believes that when one or both parents are in the state of obesity, the child born at this time is likely to carry the obesity gene, carrying the obesity gene children will be more likely to become fat than others. In addition to obese parents compared to normal weight parents to participate in physical activity less, but also generally high-fat diet habits, such habits also create a very easy for children to become fat environment. In addition to genetics, acquired living environment, birth weight is also an important factor for parents to influence their children to become fat. A study shows that when the child’s birth weight increases by 100g, his risk of childhood obesity will increase by about 1.1%, and when the birth weight exceeds 3575g, his risk of childhood obesity will increase significantly. The birth weight and the mother’s weight during pregnancy and diet have a relatively large relationship, generally the higher the weight during pregnancy, the more diet, the higher the birth weight of the child will be. So stop thinking that getting fat is just your own business, when one person in the family gets fat, it increases the chances of other family members getting fat, and the impact on the child is especially serious. Whether it’s for yourself or your family, losing weight as early as possible is a very necessary thing.
