Q. People tell me to only eat chicken breast meal prep boxes when dieting; why exactly is this helpful?

Many people start with an overzealous commitment to just chicken breast and sweet potatoes, only to burn out and binge eat. Having experienced those dietary pitfalls, I can tell you that the core of these meal boxes is 'eliminating unnecessary saccharides.' When excessive energy enters the body, the surplus is stored as fat; a protein-centric diet slows this process by preventing spikes in blood glucose. However, there is an important caveat. Simply forcing protein into your system is not always beneficial. In TKM, we place great importance on the function of the digestive organs. If a person suffers from Spleen Deficiency (脾虛, Bi-heo)—a state where digestive capacity is weakened—insisting on a high-protein diet can be counterproductive. Undigested food remains stagnant in the body and transforms into Phlegm-Fluid (痰飮, Dam-eum). When this sticky metabolic waste accumulates, you may actually feel heavier and more bloated. Furthermore, those with Blood Stasis (瘀血, Eo-hyeol), caused by poor circulation, tend to react more sensitively to sudden dietary changes. Therefore, it is more important to ask 'Is my body ready to digest this?' rather than just 'What should I eat?' To achieve sustainable weight loss without the yo-yo effect, you must adjust your diet to align with your specific digestive state and constitutional type (Sasang typology).
