Q. What does the average body fat percentage for women actually mean? I'm curious why it's so important for dieting beyond just whether someone is overweight or not.

Body fat percentage is more than just a number; it is a 'metabolic report card' of your internal health. Fat cells should not be viewed as passive storage units. When fat accumulates excessively, it releases inflammatory substances and interferes with insulin, making it difficult for the body to use energy efficiently. This leads to insulin resistance, where the body continues to store fat even when energy is available. In Traditional Korean Medicine, we treat this through the lens of Spleen Deficiency (脾虛) and Dampness-Phlegm (濕痰). When the Spleen, which is responsible for digestion and transportation, weakens, metabolic waste known as 'Dampness-Phlegm' builds up. This stagnates the circulation of Qi and Blood, causing the body to feel heavy and swollen, eventually hardening into stubborn body fat. If this stagnation persists, it can lead to Blood Stasis (瘀血), causing symptoms like lower body edema or numbness. Weight loss is not just about decreasing a number; it is about restoring Spleen function to clear out Dampness-Phlegm. By removing waste and tonifying vital energy, the body can naturally begin to burn fat. This is why a personalized prescription based on your specific constitution is essential for sustainable health.
