On an ordinary weekend morning, Uncle Zhang sat at his table as usual, ready to enjoy his standard breakfast: two slices of whole-wheat bread and a glass of low-fat milk. But unlike usual, he found himself hungry again just an hour after eating. This has been going on for several weeks. At first, he thought it was just because he was more active, but even on quiet days, this irrepressible hunger came back from time to time. He began to wonder if this was a sign of some undetected problem in his body.
The Hunger Mystery: How Does Our Body Tell Us We "Need Food"?
When we talk about hunger, we're actually talking about a complex physiological process. Hunger is not just a feeling, it is the result of multiple systems within the body working together to maintain our energy balance and nutritional needs.
At the heart of energy balance: gastric hunger signals
When our stomach is empty, it releases a hormone called ghrelin. This hormone is transmitted to the brain, especially an area of the brain called the hypothalamus, which stimulates our hunger.
Blood sugar levels: Another key factor for hunger
After food is digested, the rise and fall of blood sugar levels is another important factor that triggers hunger. A drop in blood sugar causes insulin levels to decrease, while increasing ghrelin levels, further increasing hunger.
Hormone regulation: the body's chemical messengers
Insulin and glucagon are key hormones that regulate blood sugar levels. Not only do they affect our energy stores, but they also affect the brain's perception of hunger and satiety.
Food types and hunger
Foods that digest quickly, such as simple carbohydrates, can quickly raise blood sugar and then drop it, leading to a rapid return of hunger pangs. Protein- and fiber-rich foods provide a longer feeling of fullness.

Hunger Signals: Reveal hidden health alerts
Abnormal glucose metabolism: a close relationship between hunger and blood sugar fluctuations
Abnormal glucose metabolism, often referred to as diabetes, is a condition that affects how the body processes blood sugar (glucose). When blood sugar levels are unstable, it can lead to frequent hunger pangs. In this case, the body may not be able to use blood sugar as energy efficiently, which can lead to a drop in energy levels, which in turn triggers hunger pangs. It's important to note that constant hunger pangs may be a way for the body to try to replenish energy, especially if blood sugar levels fluctuate.
Hyperthyroidism: Constant hunger triggered by hypermetabolism
Hyperthyroidism is a condition in which the thyroid gland produces too much thyroid hormones, which speeds up the body's metabolic processes. An increase in metabolic rate means that the body expends energy at a faster rate, which can lead to constant and unusual hunger pangs. Even with normal or increased food intake, people may still experience weight loss, which is another typical symptom of hyperthyroidism.
Problems with digestion and absorption: Leads to nutritional deficiencies and increased hunger
Diseases of the digestive system, such as chronic gastritis and intestinal malabsorption, may lead to inadequate digestion and absorption of food and nutrients. Persistent hunger pangs may occur when the body is unable to effectively absorb the nutrients it needs from food as the body tries to meet its basic nutritional needs. This type of hunger can occur at the same time as an upset stomach or other digestive problems after eating.
When hunger isn't just about the stomach – explore the psychological and lifestyle implications
When discussing the phenomenon of frequent hunger, we often ignore the influence of psychological factors and daily Xi. This section will delve into hunger caused by non-physiological conditions and provide practical advice.
Psychological factors: the subtle connection between emotions and appetite
The influence of mental state on appetite cannot be ignored. Stress, anxiety, or mood swings can lead to loss of appetite or excessive hunger. For example, when people are stressed, the body releases hormones such as cortisol, which can increase hunger and appetite. Mood swings, especially feelings of sadness and loneliness, can also cause people to seek food for comfort. Understanding and identifying the reasons behind these emotions is the first step in controlling abnormal hunger.
Lifestyle Influences: The Relationship Between Eating Xi and Hunger
Eating Xi is equally important for managing hunger. While foods high in sugar and carbohydrates can provide energy quickly, they can also cause blood sugar levels to rise and fall rapidly, which can increase hunger. In contrast, foods rich in protein and fiber can provide a more durable feeling of fullness. Therefore, adjusting the diet to reduce the intake of processed foods and sugars, and increase the intake of whole grains, vegetables and high-quality proteins is the key to effectively managing hunger.
Advice & Practice
Emotion management: Learn to identify and manage emotions that cause changes in appetite, such as relieving stress through meditation, yoga, or counseling.
Dietary modifications: Choose foods that are low in sugar, high in fiber, and high in protein, such as whole grains, nuts, vegetables, and lean meats, to provide a fuller feeling for longer.
Xi habits: Maintain regular eating schedules and avoid long-term fasting or overeating.
