Q. There are so many diet protein shakes and supplements these days. How should I take them while receiving Korean medicine treatment?

I completely understand the temptation to stock up on protein supplements the moment you commit to a diet. However, simply consuming large amounts of protein is not a universal solution. From a Traditional Korean Medicine (TKM) perspective, we must first examine the state of your Spleen System (脾系) to see if your digestive organs can handle the load. If you have Spleen Deficiency (Bi-heo), a high-protein diet can actually become 'toxic,' leading to indigestion, gas, and constipation rather than healthy metabolism. In these cases, it is better to undergo treatment to improve digestive function while gradually adjusting your intake. Furthermore, many supplements containing artificial sweeteners can contribute to the accumulation of Phlegm-fluid (痰飮), which is metabolic waste that hinders weight loss. Instead of relying only on liquid shakes, try incorporating natural proteins like tofu or white fish. The act of chewing stimulates digestive enzymes and prevents waste buildup. It is also important to maintain the flow of Qi and Blood (氣血) with fiber and hydration. Without sufficient 'Blood'—the fundamental material for building muscle—excessive protein will only leave you feeling fatigued. Because overconsumption can also lead to Blood Stasis (瘀血) by making the blood 'turbid,' supplements should only play a supporting role to a balanced diet and circulation-enhancing treatments. The core of TKM dieting is not just what you eat, but how effectively your body utilizes those nutrients.
