Costco offers a vast array of diet foods like chicken breast and konjac, but following trends blindly can often make your body feel heavier. In clinical practice, we see that the 'right' food varies significantly from person to person. First, evaluate your digestive capacity, specifically regarding Spleen Deficiency (Bi-heo, 脾虛). If someone with a weak Spleen insists on eating only cold salads or raw vegetables, they may experience a loss of energy and a chilled abdomen. In such cases, it is wiser to eat cooked vegetables or proteins with warm properties. Next, consider the state of Phlegm-Fluid (Dam-eum, 痰飮), which refers to accumulated metabolic waste. Processed diet foods loaded with artificial sweeteners or sugar substitutes can hinder fluid metabolism and lead to edema (swelling). Therefore, we recommend minimally processed, whole-food ingredients. One should also consider Blood Stasis (Eo-hyeol, 瘀血), which obstructs circulation. If someone with poor blood flow cuts out fats too drastically, they may become hypersensitive and fatigue easily. It is essential to incorporate healthy fats, such as high-quality nuts or olive oil. Finally, it is crucial to distinguish between physical hunger and 'psychological hunger.' Relying solely on restrictive diet foods often triggers a compensatory psychological response, leading to binge eating. The core principle is whether 'your body feels comfortable.' A diet tailored to your current digestive state and overall condition is far more sustainable than following trends. Rather than struggling through trial and error alone, visiting the clinic will allow us to provide a detailed food guide specifically tailored to your constitution.
