In my consultations, I typically encounter two main types of patients. The first group has strong willpower, but their bodies don't respond. In Traditional Korean Medicine (TKM), this is often diagnosed as Spleen Deficiency (脾虛), where weakened digestive function prevents proper energy utilization and leads to the accumulation of metabolic waste. For these individuals, extreme fasting is counterproductive; instead, prescriptions that boost 'Qi' and elevate basal metabolism are essential for successful weight management. The second group consists of those suffering from the 'yo-yo effect' or side effects after using conventional pharmaceutical diet pills. In such cases, the body often harbors 'Eohyeol' (瘀血, stagnant blood) or 'Dameum' (痰飮, abnormal fluid accumulation), which severely hinders metabolic efficiency. Rather than jumping into potent stimulants, the priority here is a detoxification process to clear these wastes and restore internal balance. Even with meticulous prescribing, individual responses vary. Some adapt quickly, while others are highly sensitive. Therefore, rather than following anecdotal success stories, the safest and most reliable approach is to accurately diagnose your current physiological state and iteratively refine the herbal formula to match your body's needs.
