Many people believe that as long as the calorie count is low, the diet is successful, but relying on low-calorie snacks can be counterproductive. Most of these snacks replace sugar with artificial sweeteners; when the brain tastes sweetness without receiving actual nutrients, it creates a metabolic confusion. Over time, this can affect insulin resistance and trigger a vicious cycle of slowing metabolism. In Traditional Korean Medicine, this state is often diagnosed as Spleen Deficiency (Bi-Heo, 脾虛). The 'Spleen' in TKM refers to the overall digestive and absorptive function of the body. When this function is impaired, the body cannot efficiently convert nutrients into energy and enters a 'survival mode.' In this state, the body conserves energy even when intake is low, making weight loss extremely difficult. Furthermore, if this is compounded by the accumulation of Phlegm-Fluid (Dam-Eum, 痰飮)—metabolic waste products—or Blood Stasis (Eo-Hyeol, 瘀血) that hinders circulation, you will experience increased heaviness and swelling. The key is not simply 'eating less,' but rather 'creating a body that burns energy efficiently.' We should determine whether your metabolic switch is currently off or if the issue lies in your dietary composition. I encourage you to visit the clinic for a comprehensive evaluation of your current physiological state.
