How exactly do the popular weight loss medications these days work to help lose weight?
Essentially, they work by tricking 'false hunger.' They send satiety signals to the brain to suppress appetite and slow down gastric emptying in the stomach, allowing you to feel full longer. This creates a cycle of [appetite suppression → reduced food intake → increased energy expenditure]. However, because they forcibly adjust the body's natural rhythms, some people may experience nausea or indigestion depending on their constitution.
From a modern medical perspective, these drugs mimic a hormone called GLP-1 to regulate the appetite center of the brain, effectively silencing 'false hunger'—the craving for food even when you are not physically hungry. However, there is a crucial perspective to consider here.
Traditional Korean Medicine (TKM) looks beyond the act of 'eating less' to examine the fundamental internal environment: 'Why do I keep wanting to eat?' For instance, an accumulation of Dam-eum (痰飮, phlegm-fluid), which are metabolic waste products, can stagnate metabolism, making a person prone to swelling and weight gain even with minimal intake. Similarly, Bi-heo (脾虛), or Spleen deficiency, impairs the transport and absorption of nutrients, causing the body to constantly crave energy.
If these are coupled with Eo-hyeol (瘀血, blood stasis/stagnant blood), weight loss may feel sluggish due to edema or inflammatory responses, even if appetite is suppressed by medication. In clinical practice, I have found that forced starvation is not the answer. To break the cycle of the 'yo-yo effect,' it is essential to first restore metabolic balance. It is vital to determine whether your current struggle is a lack of willpower or a dysfunction in your body's internal physiological mechanisms.
