I once blindly trusted popular low-calorie recipes, only to experience bloating and a total loss of energy within a few days. I learned the hard way! (laughs) From a TKM perspective, keep these three points in mind when choosing diet drinks: First, consider your digestive state. If you often feel cold in your abdomen or experience frequent diarrhea, you likely have 'Bi-heo' (脾虛, Spleen Deficiency). In this state, constantly consuming iced drinks further slows down your metabolism, potentially making it harder to lose weight. Second, check for the stagnation of waste products. Those with a high prevalence of 'Dam-eum' (痰飮, a condition where bodily fluids fail to circulate and become viscous/stagnant) are sensitive not only to sugar but also to dairy and artificial sweeteners, which can easily lead to edema (swelling). Finally, examine your blood circulation. When there is a prevalence of 'Eo-hyeol' (瘀血, blood stasis/stagnant blood), the basal metabolic rate drops significantly. In such cases, instead of relying solely on the stimulating effects of caffeine, it is far more efficient to incorporate warm-natured teas to facilitate circulation. Therefore, I suggest the following approach: First, accurately identify your digestive capacity and constitutional type. Then, carefully examine whether the cold properties or artificial additives hidden behind the label 'low-calorie' are putting a burden on your internal organs. Whenever possible, maintain your body temperature with warm or lukewarm drinks to keep your metabolism active. Ultimately, the answer lies not in a recipe that others claim is good, but in a beverage that your own body feels comfortable with. If you are curious about your exact physical condition, please feel free to visit the clinic. Let's figure it out together.
