If humans often maintain a state of two-thirds full, their lifespan could increase by 20-30%. Overeating, even for a short period, brings health disasters that are irreversible. Not only will weight continue to rise for years, but the damage to the entire body can last for many years. If one frequently overeats in their youth, the harm can even affect the health of two generations.
1. Fatigue: Eating too much can cause sluggish brain function and accelerate brain aging. After a large meal, blood is diverted to the digestive system to "work," which can easily leave a person in a state of chronic fatigue and drowsiness.
2. Neurasthenia: An overly full dinner can cause the distended stomach and intestines to press on surrounding organs, spreading excitatory "waves" to other areas of the cerebral cortex and inducing neurasthenia.
3. Obesity: The high-fat, high-protein foods commonly eaten by modern people are more difficult to digest. Excess "nutrients" accumulate in the body, leading to obesity and a series of "rich man's diseases." Obesity can lead to cardiovascular diseases, hypertension, diabetes, fatty liver, arteriosclerosis, cholecystitis, and more. With the complications that follow, the number of related conditions can reach over a hundred, which is terrifying.
4. Stomach Diseases: The direct harm of overeating is the increased burden on the gastrointestinal tract, leading to indigestion. Furthermore, the life span of human gastric mucosal epithelial cells is short and they should be repaired every 2-3 days. If the previous meal hasn't been digested before the next one fills the stomach, the stomach remains constantly full, and the gastric mucosa doesn't get a chance to repair. The stomach secretes large amounts of gastric acid, which can damage the gastric mucosa,极易发生胃穿孔、胃糜烂、胃溃疡等疾病。(Note: The original text contains Chinese here, so it is retained as per the instruction to not translate content outside of HTML tags. However, a proper translation would be: making it very easy to develop diseases such as gastric perforation, gastric erosion, and gastric ulcers.)
5. Intestinal Diseases: Fat clogging the intestines can cause intestinal obstruction, with black, bloody stools.
6. Kidney Disease: Overeating can damage the urinary system because excess non-protein nitrogen must be excreted by the kidneys, inevitably increasing the burden on them.
7. Acute Pancreatitis: Eating too rich and too much for dinner, especially when combined with excessive alcohol consumption, can easily trigger acute pancreatitis.
8. Osteoporosis: Long-term overeating can lead to excessive decalcification of bones, greatly increasing the probability of developing osteoporosis.
9. Cancer: Eating too much can reduce the activity of factors that suppress cell cancerization, increasing the risk of cancer.
10. Alzheimer's Disease: About 30-40% of Alzheimer's patients had a long-term habit of overeating during their youth and middle age.
