How do these trendy 2-week short-term diets actually work, and why are they effective?
Short-term diets work by drastically reducing caloric intake to rapidly deplete glycogen stores and excess water. From a modern medical perspective, lowering insulin levels forces the body to burn stored carbohydrates for energy, releasing water in the process. In Traditional Korean Medicine (TKM), resting the digestive system helps expel 'Dameum' (phlegm-fluid retention), which promotes metabolic circulation and reduces bloating, leading to a quick drop in scale weight.
Many people start these diets with great enthusiasm, but often end up feeling lethargic or dizzy because they simply starve themselves. The core principle of a short-term diet is altering the body's energy utilization sequence; by restricting carbohydrates, the body is forced to use stored glycogen and associated water first, which explains the rapid initial weight loss.
In TKM, this process is viewed as clearing 'Dameum' (痰飮)—pathological waste products and fluids that accumulate when the body's metabolism is sluggish. Removing this buildup makes the body feel significantly lighter.
However, caution is necessary. Individuals with 'Bi-heo' (脾虛), or Spleen Deficiency, should avoid extreme fasting. Spleen Deficiency refers to a weakened digestive function that impairs the body's ability to absorb and transport nutrients. For these individuals, aggressive fasting can crash the basal metabolic rate and lead to a more severe 'yo-yo' effect (weight regain).
Rather than focusing solely on the number on the scale, it is crucial to first assess your body's innate metabolic capacity. This ensures weight management is healthy and sustainable. If you are unsure about your current physical condition, I encourage you to visit the clinic for a personalized consultation.
