In clinical practice, patients generally fall into two categories: those struggling with uncontrollable appetite and those who feel frustrated by a weight-loss plateau despite their efforts. The former often find stability through prescriptions that suppress 'false hunger,' while the latter overcome stagnation using medicinal herbs that enhance systemic circulation. From a Traditional Korean Medicine (TKM) perspective, weight gain is not merely a matter of calories. Metabolic slowdown is often caused by 'Eohyeol' (瘀血, blood stasis/stagnant blood) or 'Dameum' (痰飮, phlegm-fluid retention), which are abnormal accumulations of waste and fluids in the body. Furthermore, those with 'Bi-heo' (脾虛, Spleen deficiency/weak digestive function) may find that extreme fasting actually triggers the body to store energy more aggressively, making weight loss harder. It is important to note that not everyone has a dramatic experience. If a prescription is not precisely tailored to one's constitution, side effects such as heart palpitations or insomnia may occur. The key to success is 'precise regulation tailored to the individual.' Obtaining an accurate diagnosis of your current physiological state and receiving a customized prescription is the safest and most effective path to weight loss.
