Q. I've heard exercise is essential for weight loss, but how exactly does it work? My concern is that I feel even hungrier after exercising.

Like many others, I once struggled with gym consistency, blaming my lack of willpower until I realized as a practitioner that mindless exertion isn't always the answer. The body consumes blood glucose before tapping into fat reserves; exercise acts as the key to unlocking these 'fat stores.' By activating muscles to increase metabolic efficiency and core temperature, fat burning accelerates. From a Western medical perspective, this is a vital process for improving insulin resistance and transforming the body into an efficient energy user. In Traditional Korean Medicine (TKM), exercise is viewed as an act of clearing stagnant flow. Those who struggle to lose weight often have accumulations of Phlegm-fluid (痰飮, bodily waste) or Blood Stasis (瘀血, stagnant blood). These wastes obstruct internal pathways, leading to Spleen Deficiency (脾虛), where weakened digestive and metabolic functions cause the body to gain weight even with minimal food intake. One thing I have learned through experience is that if you force high-intensity exercise while suffering from severe Spleen Deficiency (depleted energy), your body perceives a crisis. It may trigger intense hunger pangs or significantly lower your metabolic rate to protect muscle tissue. Therefore, identifying a moderate intensity suited to your specific constitution and energy level is crucial. Rather than just sweating blindly, you must first identify and resolve the factors hindering your circulation to achieve a sustainable weight loss journey.
