In my clinical experience, I typically see two types of patients: those with high motivation but a sluggish metabolism, and those who have exhausted their vital energy (Qi) through extreme fasting. Having experienced the dizziness and lack of focus that comes with starvation myself, I truly understand those struggles. In Traditional Korean Medicine (TKM), we prioritize managing internal waste over simple calorie restriction. When blood stasis (Eo-hyeol, stagnant blood) or phlegm-fluid retention (Dam-eum, abnormal fluid accumulation) obstruct the circulation of Qi and Blood, metabolism slows down, making weight loss difficult. Furthermore, those with Spleen Deficiency (Bi-heo) often suffer from poor digestion and chronic edema. Therefore, our approach focuses on optimizing the internal environment rather than simply suppressing appetite. Using herbal medicine that does not align with one's specific constitution can lead to side effects such as heart palpitations or insomnia. I strongly recommend a thorough health assessment before starting treatment, as accurately understanding your body's unique state is the fastest shortcut to successful weight loss.
