I have personally tried extreme fasting and single-food diets in the past, and the results were predictable: my energy plummeted and I felt dizzy, which ruined my work productivity. Having gone through that struggle myself, I fully understand the desperation to see results. First, shake programs are incredibly convenient. For busy professionals, they are a lifesaver that drastically reduces meal prep time, and because calorie control is strict, it's easy to feel the initial weight loss effects quickly. However, there are clear downsides. Relying solely on liquids removes the psychological and physiological satisfaction of chewing. More importantly, it can lead to 'Bi-heo' (Spleen Deficiency), where the functional capacity of the spleen weakens. When your digestive and absorptive abilities drop, you inevitably lose energy and your overall metabolism slows down. In Traditional Korean Medicine, the core priority is first clearing out metabolic waste such as 'Dam-eum' (phlegm-fluid retention) and 'Eo-hyeol' (blood stasis). If the 'drain' is clogged, simply pouring shakes into your system won't solve the underlying issue. Ultimately, rather than debating which method is 'right,' the priority is assessing whether your body is currently prepared to properly digest and eliminate waste. The most efficient path is to combine a tailored diet with TKM treatments suited to your current condition. Let's figure out the best plan for your body together.
