A new study finds the brain's response to the sight of food is driven by immediate blood sugar levels more than genetics.
Researchers compared how appetite centers in the brains of identical twins responded to photos of different foods.
Although the twins did have similar appetites and hormonal responses to the food, the twin with the lower blood sugar had more brain activity when looking at food photos.
This suggests the brain responds more to the body's nutritional needs than any other factors.
