Eating extra servings typically shows up on the scale later, but how this happens has not been clear. A new study published today in the Journal of Clinical Investigation by a multi-institutional team led by researchers at Baylor College of Medicine reveals a previously unknown gut-brain connection that helps explain how those extra servings lead to weight gain.
Mice consuming a high-fat diet show increased levels of gastric inhibitory polypeptide (GIP), a hormone produced in the gut that is involved in managing the body’s energy balance. The study reports that the excess GIP travels through the blood to the brain where it inhibits the action of leptin, the satiety hormone; consequently, the animals continue eating and gain weight. Blocking the interaction of GIP with the brain restores leptin’s ability to inhibit appetite and results in weight loss in mice.
“We have uncovered a new piece of the complex puzzle of how the body manages energy balance and affects weight,” said corresponding author Dr. Makoto Fukuda, assistant professor of pediatrics at Baylor and the USDA/ARS Children’s Nutrition Research Center at Baylor and Texas Children’s Hospital.
