Many of us have tried various trendy diet products, but the real key is whether your body can actually handle them. Commercial diet products typically force the metabolism to increase to burn calories or manipulate hormones to suppress hunger. While Western medicine focuses on increasing the basal metabolic rate and appetite suppression, Traditional Korean Medicine (TKM) takes a different approach. Rather than simply 'eating less and burning more,' TKM asks, 'Why is my body trying to store energy in the first place?' For example, if your body is in a state of 'Dam-eum' (phlegm-fluid retention) where metabolic waste has accumulated, or 'Eo-hyeol' (blood stasis) where circulation is blocked, your metabolic efficiency drops significantly. In such cases, relying solely on appetite suppressants can leave you feeling depleted and dizzy. Particularly for those with a 'Bi-heo' (Spleen Deficiency) constitution—characterized by a weak digestive system—aggressive use of diet supplements can lead to a severe loss of vitality and a faster return to the original weight (yo-yo effect). This is because a weakened Spleen disrupts the delicate balance between absorbing nutrients and excreting waste. Therefore, the priority should be clearing the 'congestion' in your body first. Only then can any supplement or treatment work effectively. I recommend first assessing your current physical state and constitution.
