Basics & Causes
Q. I've been eating only chicken breast, but I'm not losing weight. Is it true that the purines in chicken breast can interfere with my weight loss?
A.
While protein is generally healthy, purines can become a hidden obstacle. During metabolism, purines produce a waste product called uric acid. High uric acid levels can drastically reduce metabolic efficiency, making the body resistant to weight loss. In Traditional Korean Medicine, this accumulation of waste is known as 'Dam-eum' (phlegm-fluid). It is a classic case of 'too much of a good thing'—even protein can become toxic when consumed in excess.
📝 Detailed Answer
I remember trying to build muscle myself by eating nothing but chicken breast, only to feel dizzy and fatigued. This happens because purines in chicken breast break down into uric acid. In excess, uric acid triggers inflammatory responses in blood vessels and cells, which Western medicine links to increased insulin resistance and slowed fat metabolism. Traditional Korean Medicine (TKM) interprets this through 'Bi-heo' (Spleen Deficiency), where the weakened digestive system fails to process these substances, creating 'Dam-eum' (phlegm-fluid) and 'Eo-hyeol' (blood stasis). This leads to turbid blood and blocked circulation, where chronic swelling eventually solidifies into fat. Especially after your mid-30s, when detoxification slows down, it is vital to assess your 'Qi and Blood' circulation before overloading on protein. Without the strength to discharge waste, a chicken-breast-only diet may simply result in toxin accumulation rather than weight loss.
