Q. What is the difference between 'diet pasta' and regular pasta, and why is it said to be less likely to cause weight gain?

I used to be a huge fan of flour-based noodles myself, and I remember that feeling of getting hungry again shortly after a meal, accompanied by a sudden slump in energy. After studying this deeply, I realized the culprit is the 'blood sugar spike.' Regular pasta is made from refined flour, which is digested and absorbed very quickly. To manage the sudden surge in blood glucose, the body releases a large amount of insulin; any glucose that isn't immediately used for energy is then converted directly into fat. Diet pastas made from whole wheat or legumes provide a 'protective barrier' of dietary fiber, which ensures that sugars are absorbed slowly and steadily. From the perspective of Traditional Korean Medicine (TKM), frequent consumption of refined carbohydrates can lead to the formation of 'Dameum' (痰飮, phlegm-fluid retention). Dameum refers to a state where metabolic waste products, which have not been properly processed by the body, accumulate as a sticky residue. In particular, those with a 'Bi-heo' (脾虛, Spleen deficiency) constitution—characterized by weak digestive functions—may experience stagnant energy (Qi), leading to increased bloating and a feeling of heaviness when eating refined flour. Ultimately, what you eat is just as important as how your body processes it. If you find yourself hitting a long plateau or feeling chronically heavy despite changing your diet, it may be beneficial to examine your current metabolic function and overall constitutional balance together.
