Many people believe that Subway is the definitive answer to dieting. In reality, this is only half-right. From a Traditional Korean Medicine (TKM) perspective, weight gain is not merely a result of overeating; it is often rooted in the accumulation of physiological waste and stagnant circulation. A primary factor is 'Spleen Deficiency' (脾虛). When the Spleen function is weakened, the body fails to convert nutrients into energy, storing them as fat instead. This process creates 'Phlegm-fluid' (痰飮), a type of metabolic byproduct that causes bloating and hinders weight loss. While Subway helps reduce caloric intake, TKM herbal medicine actively removes this Phlegm-fluid and promotes systemic circulation. Key differences include: 1. Goal: Subway focuses on caloric restriction, whereas TKM focuses on increasing the Basal Metabolic Rate (BMR) and constitutional improvement. 2. Method: Subway relies on high-fiber, low-calorie meals. TKM uses 1:1 customized herbal prescriptions and circulation treatments. 3. Strengths: Subway offers accessibility; TKM focuses on preventing the yo-yo effect and improving accompanying symptoms like fatigue or indigestion. Furthermore, chronic dieting can lead to 'Blood Stasis' (瘀血), where impaired circulation causes the body to become cold and resistant to weight loss. In such cases, even the healthiest salad may not yield results. TKM aims to identify these root causes and restore malfunctioning bodily systems to their normal state rather than simply relying on starvation.
