Many people rely on cold sandwiches for dieting, only to find themselves feeling bloated and lethargic. In Traditional Korean Medicine (TKM), we call this state Spleen Deficiency (Bi-heo). When the energy of the Spleen and Stomach is weakened, nutrient absorption suffers, and metabolic waste begins to accumulate. Subway's main advantage is the ability to customize fiber-rich meals, which helps prevent the formation of 'Phlegm-rheum' (Dam-eum)—internal toxins caused by poor fluid metabolism. Choosing unrefined 'Wheat' bread also prevents rapid blood sugar spikes. However, a diet centered on cold, raw vegetables can be counterproductive for those with weak digestion. A cold abdomen slows down metabolism, potentially creating a 'body that resists weight loss.' Furthermore, the sodium and sugar in pickles and heavy sauces are primary culprits for edema (swelling). For the best results, choose whole proteins like roast chicken or steak rather than processed meats, and ask to have the bread scooped out to reduce carb intake. Use olive oil, salt, and pepper to appreciate the natural flavors. Most importantly, drink warm water or tea after your meal to warm the digestive system. Since nutritional needs vary by individual constitution, please let me know if you still feel fatigued despite these dietary changes.
