Q. What exactly is processed chicken breast, and how does it affect dieting?

Processed chicken breast is a convenience food whose composition differs from natural chicken breast. It typically contains high sodium, phosphates, starches, and vegetable oils. From a Western medical perspective, these ingredients disrupt fluid balance, causing edema, and strain the liver and kidneys. Long-term use may increase insulin resistance, making fat loss difficult. In Traditional Korean Medicine (TKM), such processed foods weaken the Spleen and Stomach (pi wei) functions, leading to Spleen Qi Deficiency (bi xu). The Spleen is responsible for digesting food and transporting fluids; when impaired, dampness (shui shi) stagnates, generating Phlegm-Fluid (tan yin), often accompanied by Blood Stasis (yu xue). Phlegm-Fluid is akin to internal waste, slowing metabolism and impeding weight loss. Clinically, patients who frequently consume processed chicken breast during diets often report rebound weight gain and fatigue due to toxin accumulation rather than muscle gain. I personally experienced this when relying on processed chicken breast for convenience—it backfired. Switching to natural chicken breast and supplementing with Spleen-tonifying herbal medicine or dietary therapy can support more stable weight management.
