Q. What exactly is the popular egg diet, and why is it said to help with weight loss?

From a medical perspective, the proteins in eggs stimulate satiety hormones, reducing 'false hunger.' Because it prevents insulin spikes, the body naturally shifts into a fat-burning mode. However, from the perspective of Traditional Korean Medicine (TKM), there are important precautions. Specifically, for those with Spleen Deficiency (Bi-heo, 脾虛), a rigid high-protein diet can be problematic. When the Spleen function is weak, the body struggles to metabolize proteins, leading to symptoms such as bloating and dizziness—complaints frequently heard in clinical settings. Furthermore, such extreme dietary restrictions can lead to the accumulation of Dam-eum (痰飮), which refers to metabolic waste and stagnant fluids in the body. An excess of Dam-eum can slow down overall metabolism, potentially altering the body's constitution to one that is more prone to weight gain in the long run. Ultimately, the issue is not whether eggs are inherently good or bad, but whether your digestive system can handle this level of protein. Rather than blindly following trends, assessing your own constitutional health is the essential starting point for a sustainable diet without the yo-yo effect.
