Although obesity is caused by multiple factors, for simple obesity, dietary factors, especially poor eating habits, are the main causes of weight gain. These mainly include:
Eating too quickly
Most obese people have a good appetite and eat very quickly, leading to wolfing down food without sufficient chewing. This prevents the food from becoming chyme that adheres to the stomach wall, so they often feel hungry even after consuming a considerable amount. At the same time, because the chewing time is too short, the vagus nerve remains overly excited, leading to increased appetite. Furthermore, after eating too quickly, blood sugar concentration rises, and by the time the brain's appetite center sends a signal to stop eating, excessive food has often already been consumed.
Constant snacking
Some obese people, especially children and young women, may not eat much during main meals, but they snack constantly, causing the total accumulated calories in their bodies to far exceed the required amount.
Skipping breakfast
Many women adopt a "starvation diet," attempting to lose weight by eating less or even skipping breakfast. However, the result is often the opposite, or even counterproductive. Because skipping breakfast enhances the feeling of hunger at lunch, which promotes food absorption. A rich lunch is quickly absorbed and converted into fat, leading to obesity over time.
Improper dinner
Many people, due to time constraints, are used to eating simple breakfasts and lunches. But in the evening, when they gather with family and have ample time, they fill the table with chicken, fish, meat, eggs, and vegetables. This arrangement is not scientific. Because after food is digested, a portion enters the bloodstream to form blood lipids. In the evening, the insulin content in the blood peaks for the day. Insulin can convert blood sugar into fat, which then accumulates on the walls of blood vessels and the abdomen. Over time, this leads to obesity.
Excessive sugar intake
Sugar is not only easily absorbed but also enhances the activity of enzymes required for fat production and stimulates the secretion of insulin, which promotes fat synthesis, thereby leading to fat accumulation.
Picky eating
Picky eating can lead to an imbalance in nutrient intake, causing a deficiency in certain nutrients. As is currently known, a deficiency in vitamin B can lead to obesity. Because vitamin B helps convert fat into energy. The B vitamins involved in fat metabolism mainly include B1, B2, B6, etc. These vitamins are mainly found in brown rice, wheat bran, and many fresh vegetables and fruits.
