Socrates without obesity: The brain is a high-energy-consuming organ; eating with the brain.

In fact, the brain is constantly functioning. To analyze this in detail, the brain's energy expenditure is 20% of the basal metabolic rate (for a male weighing 63 kg). The second largest component is the brain itself, accounting for about 18%, which consumes approximately 320 calories-the same as an hour of jogging. Because the brain uses glucose as its sole energy source, it consumes 80 to 85 grams of enzymes daily. The brain only accounts for 2% of body weight, but its calorie expenditure is enormous.

If we consider the daily calorie expenditure of a person by individual organs, the liver and muscles consume the most, each accounting for 20% of the basal metabolic rate (for a male weighing 63 kg). The brain is next, at approximately 18%. As the saying goes, "eat with your brain," and in recent years, a method considered effective for weight loss has been found to be the brain's ability to actively metabolize calories, resulting in a large expenditure of energy. The act of eating is closely related to the brain; the brain is essential for the body, or vice versa.

Previously, the idea that a healthy way to eat was to "eat until you're 80% full" and "eat with your brain, not your stomach" was prevalent. This was telling people that if you don't consider your health and just eat to satisfy your desires, you'll overeat. In other words, even before understanding the structure of the brain, human wisdom already recognized the importance of eating with your mind.

Eating enables the mind to function fully, thus there is a fundamental reason for using the mind to eat. We must understand what kind of food should be eaten in what way, and learn this as a habit or knowledge. Any animal learns its dietary habits during its growth and education. This is even more important for humans. Humans' principles of nutrition-the foundation for more efficient intake and absorption-are all acquired through education and training. Therefore, there is a fundamental reason for using the mind to eat.

Civilization is full of contradictions. With advancements in transportation, modern people's walking ability has actually declined significantly compared to the past. While hygiene awareness has increased, excessive emphasis on it has led to a loss of resistance to bacteria-examples of which abound. A recent example is the devastating impact of hospital-acquired infections, leaving people bewildered. The same situation now exists regarding food. For humans, food is no longer merely about satisfying hunger; it has become a pursuit of culinary culture. This has disrupted our originally normal appetite and the subtle mechanisms that control it, ultimately becoming a contributing factor to obesity and adult-onset diseases-a truly ironic situation.

However, I am not denying the value of food culture. It's not just about food itself, but also the attitudes and expectations placed upon it-it's arguably the wellspring of human action. Therefore, to fully enjoy food culture, we must restore the power to regulate our appetite normally. Modern people endure various pressures, both socially and psychologically. Our bodies are affected by the proliferation of processed foods, additives, pesticides, and environmental pollution, creating tangible and intangible stress. These factors can disrupt brain function and weaken it. Some psychologists have pointed out that "humans are animals driven by destructive instincts." Therefore, I believe now is the time to restore our original, vigorous survival power-that is, to adopt a proper diet that allows the mind to function normally.
