📝 Detailed Answer
From the perspective of Traditional Korean Medicine (TKM), alcohol is a primary cause of 'Dameum' (痰飮), which refers to the accumulation of pathological fluids or metabolic waste resulting from impaired fluid metabolism. When Dameum builds up, it obstructs the flow of Qi and Blood, leading to edema and a feeling of heaviness in the body. Furthermore, the greasy side dishes typically consumed with alcohol contribute to 'Eohyeol' (瘀血)—stagnant or 'muddy' blood—which further slows down the overall metabolism.
Additionally, chronic alcohol consumption often leads to a state of 'Bi-heo' (脾虛), or Spleen Deficiency. In TKM, the Spleen is responsible for transforming and transporting nutrients; when it is weakened, the body fails to produce energy efficiently and instead accumulates waste. This creates a vicious cycle where weight loss becomes difficult even with a reduced caloric intake.
By quitting alcohol, you reduce the accumulation of Dameum and Eohyeol, thereby improving blood circulation. This restores the suppressed metabolic functions, leading to natural weight loss. However, rather than simply abstaining from alcohol, identifying exactly where your systemic blockages are and treating them accordingly will allow you to recover your health and manage your weight much more effectively.
