According to Chinese medicine, the health of the Liver organ is crucial for metabolic health and maintaining a normal weight. How do you keep your Liver healthy and strong? Remember, the Liver is the organ that is most affected by emotional stress, and not being able to express yourself and follow your true desires. If you have a lot of stress, repressed anger or discontent in your life, your Liver function will be compromised. And because it’s such an important organ for digestive health, your metabolism will also eventually become compromised, and you’ll start piling on the pounds, little by little. In simple terms, stress can make you gain weight.
