Genetic Factors
There's a close connection between the obesity in parents and the obesity in their children. Oftentimes, the children born to obese parents also become obese.
Seventy percent of children with obese parents are also obese. When only one of the parents is obese, 40% of the children are obese, and when neither of the parents is obese, only 10% are obese.
Genetically, obese people store more energy as fat than do normal people.
Obese people, genetically, have a lower basal metabolism.
Social, Environmental, and Psychological Factors In developed countries, obesity occurs frequently among the lower classes, whereas in underdeveloped countries, obesity occurs more frequently among the upper classes.
The lowest body fat percentage is genetically set, but the maximum percentage is heavily affected by the person's environmental factors.
Dissatisfaction and stress can cause obesity.
Endocrine and Hypothalamus Problem Obesity can be caused by endocrine disorders, hypothalamus dysfunction, hypophysis tumors, and pineal gland tumors.
Overeating Most of the time, the reason for obesity is overeating.High calorie intake and low energy consumption result in obesity.Excessive eating as a result of stress increases the amount of fat and causes obesity.Eating too much after not eating for a while, and other irregular eating habits, can cause obesity.
Overdrinking Among people who consume excess alcohol, there are many obese people.Excess calories from alcohol cause obesity.
Lack of Exercise As life becomes more convenient and mechanical, most people don't like to walk or use stairs and opt for cars and elevators, further compounding a chronic lack of exercise that many people experience.The body stores more energy when energy is not exerted. The lack of exercise causes the body to naturally deposit fat throughout the body.Compared to people who do manual labor, people with office jobs have a greater chance of becoming obese, despite more working hours, because less energy is exerted. |
