Brain Chemistry Sheds Light on Overeating and Memory

Fruit flies use the neurotransmitter octopamine to decide whether food memories are stored long-term or short-term. This process, influenced by energy reserves, affects future eating behavior. High glycogen levels result in stable food memories, prompting increased food intake even after fasting. The research suggests that similar mechanisms may influence overeating in humans.

Brain Discovery May Lead to Solutions for Overeating

Neurons in the infralimbic cortex control the link between food cues and behavioral actions, such as overeating or bad food choices. When these neurons are regulated, the rat models consumed fewer treats.

The neurobiology of noshing: Why is it so easy to overeat calorie-rich tasty foods?

Prepronociceptin expressing neurons in the central amygdala become activated by consuming palatable foods. Reducing nociceptin making neurons in mice reduced binge eating when the animals had access to calorie-rich foods, without affecting the intake of ordinary dietary needs. The finding could help in the development of new therapies to combat obesity and binge eating.

Destructive Mechanism That Blocks the Brain from Knowing When to Stop Eating Identified

Researchers report mice fed a high fat diet produce an enzyme called MMP-2, which results in leptin being blocked from binding to its receptors. This, they report, prevents neurons from signaling that the stomach is full. The study suggests blocking MMP-2 may help people with obesity to lose weight.
