📝 Detailed Answer
I have personally experienced the discomfort of bloating after consuming too much protein powder in an attempt to build muscle, and I see many patients in my clinic with similar complaints. While supplements are a convenient way for busy professionals to prevent muscle loss and stay full, they should be used with caution from a Traditional Korean Medicine (TKM) perspective.
The whey protein found in most supplements can lead to Spleen Deficiency (脾虛) in certain constitutions. In TKM, when Spleen Qi is weakened, the body cannot effectively transform and transport nutrients, leading to the accumulation of 'Phlegm-fluid' (痰飮)—a type of metabolic waste. This often manifests as skin breakouts, abdominal gas, or even brain fog and headaches. Furthermore, consuming protein in liquid form bypasses the chewing process, which is vital for the smooth circulation of Qi and Blood (氣血). Over time, this lack of digestive stimulation can weaken the stomach's natural function, making it difficult to digest regular meals.
If you have a robust digestive system and engage in intense physical activity, supplements can be a helpful tool. However, if you are prone to edema (swelling) or have slow digestion, I recommend focusing on a natural, whole-food diet instead. The core of dieting is not just about following trends, but about choosing foods that your stomach can process with ease and comfort.
