Q. There are so many diet protein shakes and products on the market. How do they differ from a standard healthy diet, and which one would be better for me?

I once focused solely on efficiency and replaced meals with protein shakes. Over time, I noticed that despite feeling full, I lacked energy and felt dizzy due to poor digestion. Through this experience, I realized that the human body does not function simply by meeting numerical nutrient requirements. From a Traditional Korean Medicine (TKM) perspective, many people suffer from 'Bi-heo' (脾虛), or Spleen Deficiency. When the Spleen's function is weak, processing highly concentrated protein products can lead to the formation of 'Dam-eum' (痰飮)—the accumulation of metabolic waste—which can make the body feel heavier. Furthermore, if blood circulation is poor and 'Eo-hyeol' (瘀血, blood stasis) occurs, weight loss may slow down. Here is a summary of the differences between the two approaches: - Protein Products (Shakes, etc.): * Pros: Zero preparation time, easy protein supplementation. * Cons: Potential digestive strain, lack of satiety from chewing. * Recommended for: Those with extreme time constraints or those engaging in intense strength training. * TKM Perspective: Use with caution if Spleen Deficiency (Bi-heo) is present. * Key Point: Use as a supplementary tool. - Standard Diet Management (Whole Foods): * Pros: Balanced nutrients, higher digestion and absorption rates. * Cons: Cumbersome preparation, need for calorie tracking. * Recommended for: Those with weak digestion or those seeking orthodox health management. * TKM Perspective: Favorable for overall Qi and Blood circulation. * Key Point: Use as the primary source of nutrition. Ultimately, the answer lies in your body's condition. If you insist on products while your digestive capacity is low, your metabolism may actually decrease. I recommend first assessing your current digestive and metabolic health and then finding the optimal ratio between the two methods.
