Have you ever encountered this perplexing situation: you clearly do not eat much, and may even strictly control your diet, yet your weight refuses to budge, as if you "gain weight even from drinking cold water"? What is even more frustrating is that not only can you not lose weight, but you also constantly feel utterly exhausted, panting for breath even after the slightest exertion—what exactly has gone wrong? From the perspective of Traditional Chinese Medicine (TCM), this kind of "stubborn fat" is not simply a matter of excess calories, but may be related to the "qi" and "water" within the body. Today, from the angle of TCM popular science, we will discuss this headache-inducing topic, attempting to explore the deeper logic behind it from three dimensions: etiology and pathogenesis, pattern differentiation, and daily regulation.
Why Do You "Gain Weight Even from Drinking Cold Water"?—Etiology and Pathogenesis in the Eyes of TCM
Many people simply attribute weight gain to eating too much and moving too little, but there is a group of people who eat lightly and exercise reasonably yet still see their weight climb. How does TCM view this phenomenon? The answer may lie in the relationship between the "spleen" and "dampness."
Etiology: Spleen Deficiency with Dampness Excess Is the Root
TCM holds that the spleen governs transportation and transformation and is the core hub of digestion and absorption in the human body. It is responsible both for converting food into refined substances (what TCM calls the "source of qi and blood generation") and for maintaining the normal operation of water-fluid metabolism. When spleen function weakens for various reasons—such as prolonged improper diet, excessive worry and overthinking, or prolonged sitting with little movement—the spleen's transportation and transformation capacity declines, and water fluids can no longer be distributed and excreted in a timely manner. Instead, they stagnate within the body and congeal into "phlegm-dampness." Phlegm-dampness is viscous and sticky in nature, readily encumbering the viscera and meridians, manifesting as weight gain, bodily edema, and heaviness of the head and body. At the same time, spleen deficiency leads to insufficient generation of qi and blood, leaving the person fatigued, weak, and disinclined to move—this is precisely the core reason why "gaining weight even from drinking cold water" and "feeling utterly exhausted" coexist.
In TCM theory, there are two acupoints commonly used to understand the relationship between spleen-stomach transportation and transformation and water-dampness metabolism. Zusanli, also known as Xialing or Sanli, is located on the anterolateral aspect of the lower leg, 3 cun below Dubi, one finger-breadth from the anterior crest of the tibia. It belongs to the Foot Yangming Stomach Meridian and is the He-Sea point of the Stomach Meridian and the lower He-Sea point of the Stomach. The Lingshu states: "When pathogenic factors are in the spleen and stomach, the disease manifests as muscle pain... all are regulated through Zusanli." It is a representative acupoint for regulating the spleen and stomach and transforming water-dampness. Its anatomical layers are: skin → subcutaneous tissue → tibialis anterior muscle → interosseous membrane of the leg. When spleen deficiency causes ineffective transportation and internal generation of phlegm-dampness, corresponding reactions often appear in the Zusanli region; therefore, TCM practitioners frequently use it to observe the rise and fall of spleen-stomach function. The other is Yinlingquan, also known as Yinling or Lingquan, located on the medial aspect of the lower leg, in the depression between the lower border of the medial condyle of the tibia and the medial border of the tibia. It belongs to the Foot Taiyin Spleen Meridian and is the He-Sea point of the Spleen Meridian. The Zhenjiu Dacheng records that it "governs cold in the abdomen and lack of appetite." This acupoint reflects the spleen meridian's regulatory effect on water-dampness. Its anatomical layers are: skin → subcutaneous tissue → sartorius muscle → semitendinosus muscle → medial head of the gastrocnemius muscle. For the internal retention of water-dampness and heaviness of the head and body involved in "gaining weight even from drinking water," Yinlingquan is one of the key acupoints for understanding this pathogenesis.
Disease Location: The Interplay of the Spleen, Lung, and Kidney in Water-Fluid Metabolism
Water-fluid metabolism is not the work of the spleen alone, but the result of coordinated cooperation among multiple viscera. The spleen occupies the middle jiao and is responsible for transporting and transforming water-dampness; the lung occupies the upper jiao and governs the regulation of water passages, distributing water fluids downward to the kidney and bladder; the kidney occupies the lower jiao and governs the steaming and transformation of water fluids, redistributing the clear portion throughout the body and converting the turbid portion into urine for excretion. If the spleen is deficient and cannot transport and transform effectively, water-dampness accumulates in the middle jiao; if lung qi fails to diffuse and descend, the upper source of the water passages becomes obstructed; if kidney yang is deficient, the qi transformation of the lower jiao loses its function, and water-dampness overflows into the skin—any dysfunction in these three links may lead to "internal retention of damp-turbidity," manifesting as easy edema after drinking water and difficulty losing weight.
Disease Nature: Root Deficiency with Branch Excess, Intermingling of Deficiency and Excess
From the perspective of TCM pattern differentiation, this kind of "stubborn fat" often belongs to the pattern of "root deficiency with branch excess." The so-called "root deficiency" centers on spleen deficiency, accompanied by internal deficiency such as qi deficiency and yang deficiency; the so-called "branch excess" refers to the external manifestation of pathological products such as water-dampness and phlegm-turbidity accumulating within the body. The two are mutually causative: deficiency leads to internal retention of water-dampness, and water-dampness in turn obstructs the movement of qi, further aggravating the deficiency. Therefore, simple dieting or high-intensity exercise often yields half the result with twice the effort, because the fundamental problem lies in internal imbalance of transportation and transformation, not simply an imbalance between energy intake and expenditure.
Disease Trend: The Evolutionary Process from Qi Deficiency to Yang Deficiency
The formation of this type of constitution does not happen overnight but evolves gradually. In the early stage, there may only be occasional indigestion or mild fatigue, belonging to the "spleen qi deficiency" stage; if not adjusted in time, water-dampness gradually accumulates, forming "phlegm-dampness encumbering the spleen"; over time, dampness damages yang qi, progressing to the "spleen-kidney yang deficiency" stage—at which point, not only is there fatigue, but also manifestations such as aversion to cold, cold limbs, and loose stools. Therefore, the earlier the regulation, the less the difficulty; if one has already entered the yang deficiency stage, more patient and systematic care is required.
No Energy to Exercise?—The Body's Signals of Qi Deficiency and Yang Deficiency
Despite not having done any heavy physical labor, one constantly feels exhausted and disinclined to move. Many people attribute this to "laziness." But TCM reminds us: this may be a health signal sent by the body.
Qi Deficiency: Insufficient Motive Force, Inability to Push
The "qi" in TCM possesses multiple functions including propulsion, warming, defense, and containment. Among these, the propelling function of qi is the foundation for the normal operation of visceral functions. If spleen qi is weak and pectoral qi is insufficient, the muscles of the limbs lack the nourishment and support of qi, and the person will exhibit soft and flaccid muscles, shortness of breath, fatigue, and sweating at the slightest exertion. As the saying goes, "Qi is the commander of blood"; qi deficiency also affects the movement of blood, preventing various tissues from receiving adequate nutrition and oxygen, further aggravating fatigue. In this state, high-intensity exercise is not only difficult to sustain but may also consume the already insufficient qi, leaving the body even more exhausted.
Yang Deficiency: The Furnace Fire Is Weak, Warming Function Fails
Yang qi is the "furnace fire" of human life activities, possessing the functions of warming the body and promoting metabolism. If yang qi is insufficient, it is like a weak flame in the stove, unable to fully vaporize and burn food and water, and water-dampness and fat accumulate in tangible form within the body. Many people with yang-deficient constitution not only find it difficult to lose weight but also experience aversion to cold, cold hands and feet, soreness and weakness of the lower back and knees, and thin stools, particularly common among women and middle-aged to elderly populations. If such individuals blindly adopt dieting or vigorous exercise to lose weight, the results are often counterproductive—because this further depletes the already weakened yang qi, causing the body to enter a vicious cycle of "losing more weight makes you more deficient, and the more deficient you are, the fatter you become."
When mentioning yang deficiency, TCM often associates it with the Guanyuan acupoint on the Ren Meridian. Guanyuan, also known as Dantian or Xiayou, is located in the lower abdomen, on the anterior midline, 3 cun below the umbilicus. It belongs to the Ren Meridian, is the Front-Mu point of the Small Intestine, and is also the meeting point of the three Foot Yin meridians and the Ren Meridian. The Nan Jing states: "The moving qi between the kidneys below the umbilicus is the life of a person," emphasizing its close connection with the body's congenital original qi and yang qi warming function. Its anatomical layers are: skin → subcutaneous tissue → linea alba → transversalis fascia. The aversion to cold, cold limbs, and mental fatigue commonly seen in yang-deficient individuals correspond to the pathogenesis of "cold deficiency of the lower origin" governed by Guanyuan; therefore, this acupoint is often used to understand the pathological changes of kidney yang insufficiency and failure of the warming function.
Classic Interpretation: The Neijing's "When Upright Qi Is Preserved Within, Pathogenic Factors Cannot Interfere"
The Huangdi Neijing contains a widely quoted saying: "When upright qi is preserved within, pathogenic factors cannot interfere." In modern terms: when the upright qi within the human body (including the abundance and balance of qi, blood, yin, and yang) is sufficient, external pathogenic factors—such as dampness and cold—find it difficult to invade and cause harm. Conversely, the reason why the phenomenon of "gaining weight even from drinking cold water" occurs precisely indicates that upright qi within the body is insufficient, and the ability to resist damp-turbidity is diminished, allowing water-dampness to stagnate and accumulate within the body. The deeper meaning of this classical text is not passive defense, but rather a reminder for people to value the daily care of their internal environment: when upright qi is sufficient, the body naturally returns to a state of lightness and strength. This also explains why simply "watching your mouth and moving your legs" is not enough to break the deadlock—the key lies in supporting upright qi and restoring the viscera's original transportation and transformation functions.
Stubborn Fat, Pattern Differentiation: Which Type Are You?
TCM emphasizes "treating according to the individual." Even for the same "gaining weight even from drinking cold water," different people may have different causes. When a licensed TCM practitioner conducts a comprehensive assessment through inspection, auscultation and olfaction, inquiry, and palpation, they typically differentiate constitution types from the following aspects.
Phlegm-Dampness Excess Type: Characterized by "Heaviness"
These individuals tend to have a plump body type with a soft abdomen, a pale yellow and dull complexion, slightly puffy eyelids, and a frequent sensation of phlegm in the throat. Regarding the tongue and pulse: the tongue body is enlarged with teeth marks on the edges, the coating is white and greasy or thick and greasy, and the pulse is slippery or soft and slow. Accompanying symptoms include: dizziness and heaviness of the head, soreness and heaviness of the limbs, chest tightness and gastric stuffiness, and sticky or unformed stools. From the perspective of TCM constitutionology, this type belongs to the phlegm-dampness constitution, with the core pathogenesis being spleen deficiency inability to transport and transform water-dampness, with water accumulating into phlegm.
Qi Deficiency with Laziness to Speak Type: Characterized by "Fatigue"
Individuals of this type often have little qi and are lazy to speak, with a low and weak voice, which noticeably worsens after activity. They sweat at the slightest exertion and are prone to catching colds. Regarding the tongue and pulse: the tongue substance is pale red or pale white, the tongue body is enlarged with teeth marks, and the pulse is weak and forceless or thready and weak. Accompanying symptoms include: poor appetite, abdominal distension after eating, loose stools, and a pale and lusterless complexion. The core pathogenesis is weakness of the spleen and stomach, insufficient generation of qi and blood, and inability of central qi to ascend and nourish the whole body.
Yang Deficiency with Cold-Dampness Type: Characterized by "Coldness"
In addition to difficulty losing weight and fatigue, the distinctive feature of this type is aversion to cold, especially coldness in the lower back, abdomen, and calves, with hands and feet never warm throughout the year. Regarding the tongue and pulse: the tongue is pale
