Another Reason For Moderation: Overeating Affects Your Brain

Not only does overeating make you digestive system work overtime, but it also does a doozy on your brain.


American scientists recently found that overeating stimulates a usually dormant immune pathway in the brain. Once stimulated the brain then sounds the alarm for the immune system to battle invaders that aren't really there. The overactive immune system then creates an inflammation response all over the body. Chronic inflammation leads to chronic disease like type 2 diabetes and heart disease.

The pathway between the hypothalamus, the brain center that regulates energy, and the immune system is usually inactive — a remnant of an immune system that we have evolved beyond needing. It seems that "overnutrition," a scientific term (or euphemism?) for overeating has stimulated this vestigial immune system and the consequences are making us ill.

While scientists hope this discovery can lead to a medical intervention for obesity and obesity-related illnesses, it is just another reminder that moderation is key to a healthy lifestyle.
