Having experienced the exhaustion and dizziness that comes from crash dieting myself, I can tell you that the 'process of how the body adapts' is far more important than raw speed. During the first 1–2 weeks, the focus is on discharging 'Dam-eum' (痰飮)—the accumulated phlegm-fluid and waste products—and unnecessary water. During this phase, you'll likely feel that your body is becoming 'lighter' before you see a dramatic change in the number on the scale. By weeks 3–4, we focus on clearing 'Eo-hyeol' (瘀血)—stagnant blood and toxins—which activates your metabolism. This is when you'll begin to notice a visible difference in how your clothes fit. For those with 'Bi-heo' (脾虛), a deficiency in the Spleen and digestive function, we may need to adjust the herbal dosage initially. Rather than simply using strong medication, I will personally monitor your condition and calibrate the intensity of the prescription. Regarding costs, the price varies depending on the herbal composition and the duration of the treatment. I believe the most efficient investment is not necessarily the most expensive medicine, but a prescription tailored precisely to your current state.
