The close link between obesity, metabolism, and brain function: Analyzing the potential threat of diabetes and stroke.

We are all naturally inclined to crave sweet foods. Look at babies and toddlers; they only eat sweets. They refuse to eat anything slightly bitter. Even adults love sweets and often can't resist desserts, sodas, candies, and chocolates. Sweet foods are important for the body; besides being delicious, they provide energy and raise blood sugar. However, eating too many of these foods can lead to excess calories and obesity. Furthermore, excessively sweet foods can contribute to diabetes.

Diabetes is an endocrine and metabolic disease caused by a relative or absolute deficiency of insulin, leading to disordered glucose metabolism and characterized primarily by elevated blood sugar. It may be accompanied by symptoms such as polydipsia, polyphagia, and polyuria. Obesity and diabetes are closely linked. Statistics show that obese individuals are more prone to diabetes. The incidence of diabetes in obese individuals is four times higher than in non-obese individuals, and many people are already obese before developing diabetes. In fact, both diabetes and obesity are related to insulin. Insulin promotes blood sugar levels and also promotes fat formation and deposition; excessive insulin secretion can easily lead to weight gain. Studies have shown that obese individuals have significantly higher plasma insulin levels than those of normal weight. Therefore, obesity can be considered a precursor to diabetes.

The brain is the command center of the human body. All physiological activities, including the functions of the nervous system, endocrine system, and internal organs, as well as learning ability, memory, and reactions to things, are influenced or controlled by brain function. If brain function is disordered, various physiological activities of the body may be affected. Studies have shown that obesity affects brain function and can even lead to stroke. In fact, these views are not new; similar views existed even in ancient times. For example, Liu Yuansu, a physician of the Jin-Yuan period, said in "Suwen Xuanji Yuanbing Shi": "The reason why obese people are more prone to stroke is that a person's weight is determined by the deficiency or excess of blood and qi... Therefore, excess blood and deficiency of qi lead to obesity." From this, we can see that obesity can cause blood and qi to become disordered and can lead to stroke. The reason why obese people are prone to stroke is related to poor blood circulation in the brain. Obesity can cause disordered fat metabolism, making lipids more likely to accumulate in cerebral blood vessels. In addition, disordered lipid metabolism can make the blood viscous, further obstructing blood circulation in the brain. Therefore, in addition to increasing the chance of stroke, obesity can also lead to decreased mental capacity, cognitive decline, and various brain diseases.

Obesity can disrupt fat metabolism, causing lipids to easily deposit in cerebral blood vessels and narrow them. Furthermore, blood tends to become viscous, obstructing blood circulation to the brain. Therefore, this can lead to decreased mental capacity and increase the risk of stroke.
