In mice, high-fat chow spurs birth of neurons that encourage weight gain
Cheeseburgers pack on the pounds, but in mice a high-fat diet also packs on new nerve cells in the brain. More brain cells may seem like a good thing, but these newly sprouted cells appear to trigger weight gain in the animals, a new study finds.
The results offer insight into how the brain controls weight. If the same thing happens in humans, these nerve cells may be a target for anti-obesity treatments.
“This kind of work will definitely inform how we think about the underlying factors that relate to obesity,” says endocrinologist Jeffrey Flier of Harvard Me
