I have personal experience with extreme fasting in the past, and the dizziness was so severe that I couldn't function in my daily life. Having gone through that struggle myself, I truly understand how you feel. Generally, herbal diet treatments are approached in two main directions. First, 'Metabolic Boosters' focus on suppressing appetite while significantly ramping up energy expenditure. These are effective for busy professionals or those who find it nearly impossible to rely on willpower alone. On the other hand, 'Constitutional Improvement' formulas focus on reducing edema (water retention) and promoting overall circulation. Each approach has its trade-offs. Those sensitive to stimulants may experience palpitations or insomnia with metabolic boosters, while the constitutional approach may feel slower in terms of visible results. Ultimately, the most critical factor is your current physiological state. If you have Spleen Deficiency (脾虛, Bi-heo)—meaning weakened digestive function—using a strong appetite suppressant blindly can actually be harmful. Conversely, if your body has accumulated Blood Stasis (瘀血, Eo-hyeol) or Phlegm-Fluid (痰飮, Dam-eum) due to poor circulation, we must start with circulation therapy. Therefore, rather than asking 'which medicine is better,' the first step is to identify 'what my body needs right now.' Once you visit the clinic, I will carefully analyze your condition and help you find the most comfortable and sustainable path to weight loss.
