Q. Are there any coffees or alternative beverages you would recommend while dieting?

Having personally experienced the pitfalls of relying on coffee during a busy diet—such as heart palpitations and insomnia—I believe it is more important to assess your body's condition than to simply recommend a specific drink. Black coffee and other caffeinated beverages have clear advantages: they create a state of alertness that increases energy expenditure and slightly suppresses appetite, making them useful for maintaining focus during work. However, there are significant drawbacks. In Traditional Korean Medicine, those with 'Bi-heo' (脾虛), or a deficiency in Spleen function leading to poor digestion, may experience stomach irritation or a further depletion of energy if they drink coffee on an empty stomach. Moreover, if caffeine interferes with deep sleep, the body enters a vicious cycle of craving high-calorie sweets the next day to compensate for the energy deficit. The core issue is not 'which coffee is best,' but whether 'your body can currently handle caffeine.' If you suffer from chronic indigestion or insomnia, I recommend warm herbal teas instead. If your body is struggling with 'Dameum' (痰飮)—the accumulation of metabolic waste and fluids that hinders circulation—light teas are far more beneficial. I suggest we examine your specific condition together. If you visit the clinic, I can evaluate your digestive state and sleep quality to determine if coffee is suitable for you or if a different alternative would be more effective.
