Patients generally fall into two categories: those struggling with appetite control and those with a slow metabolism who find it hard to lose weight despite eating little. The former benefits from appetite-suppressing herbs, while the latter requires prescriptions to enhance circulation and metabolic function. In Traditional Korean Medicine (TKM), we prioritize clearing 'Dam-eum' (phlegm-fluid retention) and 'Eo-hyeol' (blood stasis)—metabolic waste products that obstruct the body's flow—over simple calorie restriction. Think of it as clearing out trash from a house before reorganizing it. For those with 'Bi-heo' (Spleen deficiency), excessive fasting often leads to rapid exhaustion and a high likelihood of the yo-yo effect. During the initial phase, you may experience dry mouth or a surge of energy that interferes with sleep. These are often natural reactions as your metabolism accelerates, but the intensity varies by person. Instead of a one-size-fits-all prescription, I act as a 'custom guide,' adjusting the potency of the herbal medicine through constant communication. Having experienced the frustrations of trial-and-error dieting myself, I understand your concerns. Let's begin by analyzing your current physical state together.
