I remember struggling with 'how to eat to make dieting less miserable' when I was losing weight myself. Sandwiches like those from Subway are actually quite decent in composition because they allow you to consume a large amount of fresh vegetables at once. On the positive side, the high dietary fiber provides long-lasting satiety and makes it easy to control carbohydrate intake. However, there are a few concerns. Raw vegetables have a 'cold' nature, which can be burdensome for those with weak digestive systems, and commercial sauces are high in calories and can spike blood sugar levels quickly. In Traditional Korean Medicine (TKM), a weakened digestive state is referred to as 'Bi-heo' (脾虛, Spleen Deficiency). People with this condition often experience bloating or stomach upset when eating cold sandwiches. Therefore, I recommend minimizing sauces and sticking to a clean taste with just olive oil and a touch of salt. For those suffering from 'Dam-eum' (痰飮, phlegm-fluid retention caused by poor fluid metabolism) or 'Eo-hyeol' (瘀血, blood stasis where stagnant blood accumulates), light options that aid metabolism—such as black pepper or red wine vinegar—are much more suitable than stimulating sauces. Ultimately, there is no single 'correct' answer. The right food varies depending on your current digestive state and overall condition. If you are curious about what your body needs right now, please visit the clinic so we can discuss it in person.
