I once tried a strict diet of just chicken breast and sweet potatoes out of sheer ambition, only to end up feeling bloated and completely drained of energy. It's a bit embarrassing to admit that even a Korean Medicine Doctor made such a mistake. High-protein diets centered on chicken breast are effective for preventing muscle loss and maintaining satiety. However, they are not suitable for everyone. In Traditional Korean Medicine (TKM), those with Spleen Deficiency (脾虛)—meaning impaired digestive function—may develop 'Dam-eum' (痰飮, phlegm-fluid retention) if they adhere strictly to such a diet. Dam-eum occurs when metabolic waste fails to be processed and eliminated, accumulating in the body. The benefits of a protein-rich diet are clear: it stabilizes blood sugar and preserves lean muscle. However, there are downsides, such as constipation due to a lack of dietary fiber. For those with sensitive digestive tracts, excessive protein can cause gas, which may even lead to a feeling of lightheadedness throughout the day. Ultimately, the answer lies in your own body's condition. If you typically have slow digestion or a 'cold' constitution, it is far better to pair proteins with warm-natured vegetables and whole grains rather than relying solely on chicken breast. Furthermore, if you have a significant amount of 'Eo-hyeol' (瘀血, blood stasis)—where blood circulation is sluggish—I recommend a gentle, balanced diet combined with light walking rather than a restrictive regime. If you are wondering whether your body is currently prepared to process a high-protein diet, please feel free to visit the clinic.
