Q. What exactly does it mean to have a body fat percentage of 25%? I'm curious why this is considered the key to dieting.

Many people make the mistake of focusing solely on weight loss through starvation, only to find that their reflection in the mirror remains unchanged. This discrepancy occurs because of the body fat percentage. From a modern medical perspective, excessive fat accumulation is linked to insulin resistance and impaired glucose metabolism. In Traditional Korean Medicine (TKM), this condition is viewed as 'Dam-eum' (痰飮)—the accumulation of unnecessary metabolic waste and fluids that obstructs the circulation of Qi and Blood. This becomes more complex if you suffer from 'Bi-heo' (脾虛), or Spleen Deficiency. When the Spleen's function is impaired, the body fails to utilize energy efficiently, leading to a tendency to store calories as fat. If this is compounded by 'Eo-hyeol' (瘀血), or blood stasis, you may experience stubborn plateaus where weight refuses to budge in specific areas despite a caloric deficit. The core of a successful diet is not simply 'eating less,' but rather restarting the body's metabolic switch. By resolving accumulated Dam-eum and Eo-hyeol and treating Spleen Deficiency, you can transform your body into one that burns fat efficiently. The priority should be identifying the root cause of why your body is clinging to fat in the first place.
