Q. I've been choosing diet-friendly drinks from places like Mega Coffee. From a TKM doctor's perspective, which ones would you most recommend?

I also rely on a cup of coffee to get through a busy day, and I fully understand the feeling because I've experienced palpitations and dizziness from overconsumption. While the caffeine in an Americano can help by stimulating metabolism, it can be counterproductive for those with a 'Spleen Deficiency' (脾虛, bi-heo) constitution—where digestive functions are weakened—as it puts excessive strain on the gastrointestinal tract. I generally do not recommend sugar-free syrups or 'zero' drinks, even if they are low in calories. Artificial sweeteners can contribute to the formation of 'Dam-eum' (痰飮, the accumulation of metabolic waste and fluids), which can make the body feel heavier and sluggish. Instead, warm herbal teas or Rooibos are far better for promoting healthy circulation. The benefits of caffeine are clear: it awakens the mind and temporarily suppresses appetite. The drawbacks, however, include disrupting sleep, irritating the stomach lining, and potentially triggering 'false hunger.' There is no one-size-fits-all answer. First, observe whether your body feels swollen and heavy, or if your energy is so depleted that you feel you must rely on coffee. Once you understand your current state, the right choice of beverage becomes clear. Let's figure this out together.
