New research found that intermittent fasting doesn’t just help with weight loss—it actually rewires your brain. Scientists discovered that fasting causes changes in the brain area responsible for controlling impulses and appetite, called the left inferior frontal orbital gyrus. Participants who practiced intermittent fasting lost about 17 pounds on average, but the most exciting part is how their brains transformed alongside changes in gut bacteria.
During fasting, beneficial microbes like Coprococcus comes and Eubacterium hallii thrived, producing compounds that travel through the bloodstream to the brain. These compounds influence brain chemistry, helping improve impulse control and possibly cognitive function. This research shows that fasting’s effects go beyond diet and metabolism—it actively reshapes brain function by linking gut health with brain activity. The findings highlight how the gut-brain connection plays a key role in controlling hunger and behavior, offering new insights for weight management and mental health.
