Q. Is it okay to drink only protein shakes while dieting? What approach do you recommend as a TKM doctor?

I used to prioritize efficiency and replace meals with shakes in my youth. While convenient at first, I eventually experienced bloating and a significant drop in energy—a cycle of trial and error many of us go through. There are clear advantages to shakes: they are ideal for busy professionals to maintain a diet and quickly replenish protein for muscle preservation. They are also excellent for curbing hunger during appetite-control phases. However, there are precautions. Since there is no chewing process, fewer digestive enzymes are secreted. Specifically, those with Spleen Deficiency (Bi-Heo, 脾虛)—where the spleen's digestive function is weak—may experience indigestion and a 'cold' abdomen if they consume cold-natured shakes continuously. Furthermore, excessive processed additives can lead to the accumulation of Phlegm-Fluid (Dam-Eum, 痰飮), causing the body to feel heavy and sluggish. Ultimately, the key is not 'which food is best,' but 'your current body state.' If you have strong digestion, occasional meal replacements are fine. However, if you have a weak stomach or suffer from severe edema, I strongly advise incorporating a natural, whole-food diet. If you feel overwhelmed by planning a diet that fits your body, I suggest visiting the clinic to evaluate your constitution and digestive status. We can work together to find the most comfortable and effective method for you.
