Many people attempt extreme fasting, only to find themselves feeling exhausted and bloated. In Traditional Korean Medicine (TKM), this condition is often viewed as 'Spleen Deficiency' (Bi-heo, 脾虛). The Spleen is the core organ responsible for transporting nutrients and filtering waste; when its function is impaired, toxins accumulate, creating a constitution that is resistant to weight loss. We recommend a systematic four-step guide to reset your metabolism: 1. Removal of Intestinal Toxins: We first clear 'Dam-eum' (痰飮), which refers to the abnormal accumulation of fluids and metabolic waste. Clearing these residues allows probiotics to colonize the gut more effectively. 2. Strengthening Digestion and Absorption: By treating Spleen Deficiency, we create an environment where nutrients are efficiently absorbed and waste is promptly expelled. 3. Promoting Blood Circulation: We resolve 'Eo-hyeol' (瘀血, blood stasis) around the abdominal area to increase metabolic efficiency. Proper blood flow is essential for accelerating fat combustion. 4. Personalized Diet and Probiotics: Finally, we integrate customized probiotics and dietary plans to maintain a healthy gut microbiome ecosystem. Ultimately, gut health is not merely about 'regular bowel movements,' but about flipping your body's metabolic switch. Since every individual's intestinal state differs, we recommend a professional consultation to determine your specific constitutional needs.
