Natural Hormone Found to Combat Obesity by Affecting Brain

A hormone that can help mice lose weight has given scientists new insights into how the brain manages body weight. Researchers at the University of Oklahoma discovered that FGF21, or fibroblast growth factor 21, works in a key area of the brain that controls hunger and metabolism. This area is also affected by popular weight-loss drugs called GLP-1.

FGF21 mainly acts in the brain, unlike other metabolic signals that target organs like the liver or fat. Scientists are interested in FGF21 because treatments using it might help conditions like MASH, a severe liver disease linked to obesity.

The study, led by Dr. Matthew Potthoff, showed that FGF21 mainly affects the hindbrain, which regulates basic functions such as feeling hungry and managing energy. Potthoff was surprised to find that FGF21 targets this area instead of the hypothalamus, another brain region known for its role in body weight.

This discovery could lead to better treatments for obesity. FGF21 raises the metabolic rate, helping with weight loss, while GLP-1 reduces food intake. Further research is needed to see if FGF21 can also help treat MASH.
