Q. What exactly is body fat percentage? I'm curious why I need to consider body fat percentage when simply reducing weight should be enough.

I used to starve myself too. At first, the scale dropped quickly and I was thrilled, but within days I felt weak and dizzy. I later learned that I had only lost muscle and water, not fat—it was classic wasted effort. Medically, a high body fat percentage signals that your body's energy efficiency is impaired. In Traditional Korean Medicine, this is interpreted through 'phlegm-fluid' (痰飮) and 'blood stasis' (瘀血). Phlegm-fluid means waste matter clogs the flow, and blood stasis means circulation stagnates with residue. When these wastes accumulate, metabolism slows and fat is more easily stored. If 'spleen deficiency' (脾虛) is also present, the problem worsens: a weak spleen cannot transform nutrients into energy, so it stores them directly as fat. This explains why some people gain weight even when eating little. Therefore, our approach is not just to reduce the number on the scale, but to clear blocked energy and restore metabolic function. This way, you lose only body fat while preserving muscle—true weight management. We always start by assessing whether your condition is spleen deficiency or phlegm-fluid.
