Everyone’s talking about Ozempic.
Something worth saying clearly before the conversation gets entirely away from us.
GLP-1 — Glucagon-Like Peptide-1 — is not a pharmaceutical invention. It is not something we have added to the body. It is something the body makes itself, has always made, and makes with remarkable intelligence when given the conditions to do so.
It is produced in the L-cells of the small intestine and colon in response to food. It signals the pancreas to release insulin. It slows gastric emptying so that food stays in the stomach long enough to be properly registered. And critically, it travels to the hypothalamus and brainstem and says, simply: enough. We have been fed.
The drugs — semaglutide, the GLP-1 receptor agonists now prescribed at extraordinary scale — are doing loudly and pharmacologically what a healthy body does quietly and continuously. They are amplifying a signal the body has lost the capacity to generate on its own.
The question worth sitting with is not whether the drugs work. They do, in measurable ways. The question is: why did the signal break down in the first place?
What Impairs the Signal
GLP-1 secretion is disrupted by a convergence of entirely modern conditions.
Ultra-processed food and refined carbohydrates blunt the L-cells' capacity to respond over time. A disrupted gut microbiome — and the microbiome lives primarily in the large intestine, producing the short chain fatty acids that directly stimulate GLP-1 release — reduces the signal at its source. Chronic systemic inflammation, the low-grade constant hum of a body under prolonged stress, impairs receptor sensitivity. Insulin resistance and impaired GLP-1 secretion reinforce each other in a feedback loop that becomes increasingly difficult to interrupt. Rapid gastric emptying means food moves through too quickly for the L-cells to register it adequately. And a sedentary body produces less GLP-1 — movement is itself a meaningful stimulator of the signal.
None of these are mysterious. All of them are lifestyle. All of them are, to varying degrees, reversible.
What Classical Chinese Medicine Knew
Two thousand years before the L-cell was identified, Chinese medicine had mapped this territory with precision.
The Tai Yin layer — governing the Spleen and Pancreas — is the classical seat of transformation and absorption. The Spleen receives what the gut has processed, transforms it into Qi and Blood, and distributes nourishment to every cell. When Tai Yin is compromised through poor food quality, cold, chronic overwork or depleted gut ecology, transformation stalls. Dampness accumulates. Weight gathers and will not shift. Appetite becomes unregulated not through failure of willpower but through failure of signal. The body is not receiving the message that it has been adequately nourished.
This is insulin resistance. This is impaired GLP-1 secretion. Described in a different language, from a different century, with the same clinical precision.
Beneath Tai Yin sits the Shao Yin layer — the Heart and Kidney axis, fire and water. The Kidney Yang is the root warmth that fires all transformation from below. Without it the Spleen cannot do its work. The gut becomes cold and sluggish, the microbiome suffers, the metabolic signal weakens. In perimenopause, as Kidney Jing naturally declines, this root fire diminishes. The Spleen loses its warmth. Dampness accumulates. The body's capacity to generate its own satiety signal — its own GLP-1 — is compromised from the root.
And then there is the Heart and Small Intestine axis within Shao Yin — perhaps the most elegant mapping of all. The Small Intestine's classical function is to separate the pure from the impure, sending what is usable upward to nourish the Heart and Shen. This is precisely what the L-cells are doing when they release GLP-1 — sensing what has arrived, assessing its quality and quantity, and sending a signal of sufficiency upward to the brain. The hypothalamus receiving GLP-1 and registering satiety is the modern description of the Small Intestine communicating with the Heart.
When this axis is disturbed, the hunger that cannot be satisfied is not only physical. It is a Shen hunger. A hunger to feel genuinely met, genuinely nourished, genuinely enough. No drug resolves that.
What Restores the Signal
The conditions that restore endogenous GLP-1 production are not complicated. They are simply slow, and they require a different kind of attention than a prescription.
Food quality over food quantity. Fibre that feeds the microbiome and stimulates the L-cells. Warmth in the gut — cooked foods, warming spices, ginger, the congee wisdom of East Asian medicine. Movement that stirs Kidney Yang and stimulates GLP-1 directly. Rest that allows the Spleen to transform rather than accumulate. The reduction of chronic stress, which is perhaps the single most powerful intervention available, because a nervous system in sympathetic dominance cannot digest, cannot transform, cannot generate the conditions for satiety.
And underneath all of that — the Shao Yin question. What is the hunger actually for? What has not been adequately nourished? Where has the body been asked to keep running on a signal it stopped receiving years ago?
These are not questions a drug asks. They are questions a body has been waiting to be heard asking for a very long time.
If something here speaks to you, you can work with me in person at my clinic in Preston and at The Yin Palace gatherings in Melbourne, or online through my qigong community and Rage Rising. The Three Treasures Pathway is offered both in person and online.
