I once tried a trendy diet myself and suffered from bloating for days—even as a professional, I made a mistake. While chicken-breast-centric diets have clear advantages in providing protein and satiety, there are important caveats from a Traditional Korean Medicine (TKM) perspective. In TKM, if a person has 'Bi-heo' (脾虛)—a deficiency in Spleen function—consuming only cold or dense high-protein foods can easily lead to indigestion. Specifically, consuming frozen products that are quickly thawed can place a heavy burden on the stomach and intestines, potentially causing dizziness or fatigue. For those with an accumulation of 'Dam-eum' (痰飮, phlegm-fluid retention), it is more important to first clear these metabolic wastes before simply increasing protein intake. Incorporating ingredients that help resolve 'Eo-hyeol' (瘀血, blood stasis) is essential for smoothing the overall metabolic flow. Ultimately, the correct answer depends on the individual. If your digestion is strong, a chicken breast diet is efficient. However, if you typically have a 'cold' abdomen and poor digestion, combining warm vegetables with moderate carbohydrates is a far healthier direction. I recommend first assessing your current digestive state before deciding on a strict regimen.
