How the Brain's Hunger Center Could Be Fueling Weight Gain

Scientists at the University of Cambridge have made a significant discovery about the brain's role in weight gain, focusing on the hypothalamus, which controls hunger and fullness.

The researchers found that individuals who are overweight or obese tend to have a larger hypothalamus compared to those with a healthy weight.

Obesity is a serious global health issue, increasing the risk of diseases such as diabetes and heart problems.

The Hypothalamus' Role

The hypothalamus plays a crucial role in determining when we feel hungry or full, but its small size has made it challenging to study in humans using conventional brain scans.

Most of what we know about the hypothalamus comes from animal studies.

To overcome this limitation, the research team, led by Stephanie Brown, utilized a novel method combining brain scans with machine learning to study the hypothalamus in humans.

Author's summary: Scientists discover link between brain's hunger center and weight gain.
