I've been eating a lot of the trendy low-calorie snacks lately. From a Korean medicine practitioner's perspective, which ones are actually good for me?

To be honest, I once went through a phase of browsing low-calorie snack malls, thinking, 'This should work' for my diet. But in reality, they often left me feeling unsatisfied, which eventually led to binge eating. While low-calorie snacks have clear advantages—such as reducing immediate guilt and alleviating the stress of boredom—they act more as a psychological tool for appetite control. However, there are important caveats. Modern sugar substitutes (artificial sweeteners) can cause gastrointestinal gas or heighten the craving for sweetness depending on one's constitution, further stimulating the appetite. In particular, those with 'Bi-heo' (脾虛), or Spleen Deficiency (weakened digestive function), are more likely to experience bloating or a sense of dizziness after consuming these artificial ingredients. Ultimately, the answer depends on your body's state. Recommendations differ based on whether you have a constitution prone to 'Dam-eum' (痰飮)—the accumulation of metabolic waste—or if you are craving sweets due to a general deficiency of Qi (energy). For the former, light nuts or vegetable sticks are ideal; for the latter, warm-natured teas or small portions of roasted grains are more suitable. Rather than blindly trusting the 'low calorie' number, the key to a sustainable diet without the yo-yo effect is observing how your body reacts to the food. If you are curious about which snacks best suit your specific needs, I recommend visiting the clinic for a formal constitutional diagnosis.
