I have a personal story here—when I was younger, I blindly followed a trending diet and suffered from a bloated stomach despite feeling full. I certainly learned my lesson the hard way! (laughs) The advantages of a chicken breast-based diet are clear: it is low in fat and rich in protein, making it highly efficient for managing weight while preserving muscle mass. Its convenience also makes it a practical choice for busy professionals. However, there is a critical point to consider. In Traditional Korean Medicine, if a person suffers from Spleen Deficiency (Bi-heo, 脾虛)—a state where the digestive function is weakened—insisting on a high-protein diet can actually be counterproductive. A body with poor digestive capacity cannot properly absorb protein, leading to the accumulation of metabolic waste known as Phlegm-Fluid (Dam-eum, 痰飮). This often manifests as a feeling of heaviness or dizziness. Furthermore, some people find the dry texture of chicken breast stressful. If this stress persists, it can obstruct the flow of Qi and Blood, potentially leading to Blood Stasis (Eo-hyeol, 瘀血). Ultimately, the core issue is not 'what you eat,' but 'whether your body can effectively process it.' Chicken breast is a useful tool, but not a universal key. If you frequently experience indigestion or lack of energy, start with vegetables or softer proteins. The fastest path to success is to assess your body's digestive capacity before finalizing your diet.
