Q. I’m always conflicted about what to eat on my cheating day. What are your recommended menus, and how exactly does a cheating day impact my weight loss progress?

I remember when I used to diet, I’d treat cheating days like a final meal, gorging on spicy rice cakes and fried chicken, only to feel dizzy the next day. Looking back, that wasn't 'cheating'—it was an assault on my body. From a medical perspective, when food intake decreases, the body naturally lowers levels of the hormone 'leptin.' Insufficient leptin causes the body to slow its metabolism to conserve energy, leading to a weight loss plateau. Providing moderate calories at this point tricks the body into thinking it no longer needs to starve, effectively flipping the metabolic switch back on. In Traditional Korean Medicine (TKM), a cheating day is a process of managing Spleen function. If you starve for too long and enter a state of 'Spleen Deficiency' (Bi-heo), the body begins to accumulate metabolic waste known as 'Phlegm-rheum' (Dam-eum), changing your constitution into one that resists weight loss. However, caution is needed: spicy and salty stimulant foods can cause 'Blood Stasis' (Eo-hyeol), leading to edema and disrupting the metabolic flow. This is why I highly recommend 'clean, high-protein' meals. Options like shabu-shabu, boiled pork slices (suyuk), sashimi, or grilled beef are excellent. These foods tonify Spleen Qi while efficiently providing the nutrients required for muscle maintenance. Think of it not just as a meal for your palate, but as a 'restorative tonic' for your metabolic system. Eating intelligently is a core skill of successful dieting.
