Stress can Curb the Desire to Eat

When a neurocircuit is activated in the mice, there was an increase in anxiety or stress levels and a decrease in appetite, finds a new study.

Particular neurocircuit in mice, when activated, increased their stress levels while decreasing their desire to eat, reports a new study. The findings of the study are published in the journal Nature Communications.//

The scientists believe their research could aid efforts to develop treatments for a serious eating disorder called anorexia nervosa, which has the highest mortality rate of any mental disorder, according to the National Institute of Mental Health. People with anorexia nervosa avoid food, severely restrict food, or eat very small quantities of only certain foods. Even when they are dangerously underweight, they may see themselves as overweight.

‘Stress can reduce a person's desire to eat. ’

"We have identified a part of the brain in a mouse model that controls the impact of emotions on eating," said Qingchun Tong, PhD, the study's senior author and an associate professor in the Center for Metabolic and Degenerative Disease at McGovern Medical School at UTHealth.

Because mice and humans have similar nervous systems, Tong, the Cullen Chair in Molecular Medicine at UTHealth, believes their findings could shed light on the part of the human brain that regulates hunger.

The investigators believe they are among the first to demonstrate the role of this neurocircuit in the regulation of both stress and hunger.

While previous research has established that stress can both reduce and increase a person's desire to eat, the neural mechanisms that act on the regulation of eating by stress-related responses largely remain a mystery.

Tong's team focused on a neurocircuit connecting two parts of the mouse brain: the paraventricular hypothalamus, an eating-related zone in the brain, and the ventral lateral septum, an emotional zone in the brain. The neurocircuit acts as an on/off switch.

Hobbies that Help You Deal with Stress
Stress is a part of everyone's routine life, but too much stress can take a toll on your body and mind. Choosing a hobby may help you relax and improve your mental health.

When researchers activated the neurocircuit, there was an increase in anxiety levels and a decrease in appetite. Conversely, when the investigators inhibited the neurocircuit, anxiety levels dropped and hunger increased.

The scientists used a research technique called optogenetics to turn the neurons in question on and off.

Techniques for Stress Relief
Stress is a part of everyday lives. It can be beneficial to an extent, but when it disrupts the equilibrium in which our nervous system is capable of performing better, it becomes troublesome.

Yuanzhong Xu, PhD, the study's lead author and an instructor at McGovern Medical School, said additional preclinical tests are needed to confirm their findings.
