Q. As a busy professional, I often grab a meal at Subway to save time. What is the best way to eat there without gaining weight, according to Traditional Korean Medicine?

Choosing a healthy lunch every day can be challenging. In Traditional Korean Medicine, weakened digestive function is known as Spleen Deficiency (脾虛). When digestion is impaired, metabolic waste called Phlegm-Dampness (痰飮) accumulates in the body, creating a constitution that gains weight easily. Here is a 4-step guide to a TKM-friendly Subway order. First, choose whole-grain bread like Wheat or Honey Oat and ask to have the bread scooped out. This is a key secret to preventing Spleen Deficiency; by reducing refined carbohydrates, you ease the burden on your digestive system and prevent blood sugar spikes. Second, fill your sandwich with high-quality, lean proteins like roasted chicken or turkey. These ingredients help replenish Qi and Blood (氣血), the fundamental energies of our body, ensuring you maintain your vitality even while dieting. Third, for the sauce, stick to olive oil, salt, and pepper. Stimulating sauces high in sugar can create Phlegm-Dampness (痰飮), which obstructs internal circulation. As you get used to the natural flavors of the ingredients, your palate will become cleaner and healthier. Finally, pair your meal with lukewarm water instead of cold drinks. Cold beverages lower the temperature of the stomach, which can lead to Water Toxicity (水毒), a state where fluid metabolism stagnates. Drinking warm or room-temperature water is much more beneficial for maintaining the metabolic heat necessary for digestion. Following these steps will help you feel less drowsy during work and keep your body feeling light. However, since everyone has a different constitution and digestive capacity, feel free to consult us for a personalized dietary plan tailored to your specific body type.
