Q. Why does everyone eat chicken breast lunch boxes when dieting? I’m curious about the exact principle of how they help with weight loss.

Managing a diet while working is no easy feat; I understand the struggle well, as I used to stock my freezer with chicken breast meals during busy clinic hours. The primary appeal of these meals lies in 'energy efficiency.' From a Western medical perspective, protein has a much higher Thermic Effect of Food (TEF) than carbohydrates or fats, meaning the body burns significant calories just during the digestion process. It also helps suppress insulin secretion, preventing fat storage. Traditional Korean Medicine (TKM) offers a different layer of insight. While chicken has a 'warm' nature that can boost energy, consuming processed, dry chicken daily can eventually impair the Spleen’s 'transportation and transformation' function, leading to a state called Biheo (Spleen Deficiency). When protein is not properly transformed, it turns into internal waste like 'Phlegm-fluid' (Dameum) or 'Blood stasis' (Eohyeol), which can paradoxically change your constitution into one that gains weight more easily. In my practice, I see many patients who feel lethargic or dizzy after forced chicken-only diets—clear 'SOS' signals from blocked Qi and Blood circulation. If you use these lunch boxes, I recommend pairing them with warm vegetables and adjusting the portion size based on your digestion. True wisdom lies in checking if your digestive system is ready to process the food rather than blindly following a popular trend.
