Q. Doctor, why does everyone say I should only eat chicken breast when dieting? Is there a specific reason why I must eat this and nothing else?

From a conventional medical perspective, chicken breast's high pure protein content prevents muscle loss and promotes prolonged satiety. However, the human body cannot function on protein alone. In Traditional Korean Medicine (TKM), individuals with 'Bi-heo' (脾虛)—a condition where the Spleen's digestive function is deficient—may experience adverse effects if they adhere too strictly to a chicken-breast-centric diet. This is because undigested protein residues can lead to the formation of 'Dameum' (痰飮), which are metabolic waste products or phlegm-fluid accumulations in the body. When Dameum accumulates, you may experience a sensation of heaviness and swelling. This stagnation can hinder the circulation of Qi and Blood, potentially creating an environment conducive to 'Eohyeol' (瘀血), or blood stasis. Consequently, an attempt to lose weight may inadvertently damage your overall health. While chicken breast is an excellent tool, the critical factor is whether your digestive capacity can handle it. If your digestive power is low, rather than following a generic trend, it is far more efficient to incorporate cooking methods and ingredients tailored to your specific constitution.
