Q. How is a constitution-improving diet different from a typical diet? I'm curious why it's less likely to cause a yo-yo effect.

Many people have experience with extreme fasting, only to face dizziness and a severe yo-yo effect. Standard diets focus solely on controlling caloric intake; however, the body is adaptive and lowers its basal metabolic rate when calories are severely restricted, which is the primary cause of weight regain. In Traditional Korean Medicine (TKM), this is viewed not as a simple calorie issue, but as a problem with the internal environment. For instance, the accumulation of Phlegm-Fluid (Dameum, 痰飮) or Blood Stasis (Eohyeol, 瘀血) can significantly hinder metabolic efficiency. Furthermore, Spleen Deficiency (Biheo, 脾虛) can impair the absorption and transportation of nutrients, leading to a constitution that gains weight easily even with minimal intake. A constitution-improving diet focuses on clearing these internal 'blockages.' By removing Phlegm-Fluid and Blood Stasis, it secures metabolic pathways and improves Spleen function to create a body that consumes energy efficiently—much like increasing the displacement of an engine to improve performance. This approach is not a one-size-fits-all solution. While some may find simple dietary management faster, others find constitutional improvement essential. The most efficient path is to receive an accurate diagnosis of your current physiological state and get a prescription tailored to your specific TKM constitution.
