Q. Everyone tells me to keep eating chicken breast meal prep kits while dieting. Why exactly is this helpful?

From a medical perspective, chicken breast is high in protein and low in fat. Focusing on protein while reducing carbohydrates prevents rapid spikes in blood glucose levels. This reduces the secretion of insulin—the hormone responsible for fat storage—creating an optimal physiological environment for the body to burn stored body fat for energy. However, from the perspective of Traditional Korean Medicine (TKM), the viewpoint differs. While a protein-rich diet can boost energy, relying exclusively on a single food source can easily lead to 'Spleen Deficiency' (Bi-heo, 脾虛). When the function of the Spleen weakens, digestive power declines, and unprocessed metabolic waste can accumulate as 'Phlegm-Fluid' (Dam-eum, 痰飮), leading to stagnation throughout the body. Ultimately, how well your body digests and metabolizes what you eat is more important than the specific food itself. While chicken breast is an excellent ingredient, for some, it may cause indigestion and edema. The key to healthy, sustainable weight loss without the 'yo-yo effect' is adjusting your diet to align with your individual digestive capacity and constitution (Sasang typology).
