The Claim
Repeated stress exposure in mice progressively reduces neural activity in the medial amygdala–ventromedial hypothalamus circuit, which results in the loss of acute stress-induced hyperglycemia and leads to the development of fasting hyperglycemia and weight gain, especially under high-fat diet conditions.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When mice are stressed over and over, their brain’s stress response system gets duller, so they stop spiking their blood sugar when scared—and eventually end up with high blood sugar and weight gain, especially if they eat a lot of fatty food.
See the scientific wording
Repeated stress exposure in mice progressively blunts neural activity in the medial amygdala–ventromedial hypothalamus circuit, leading to loss of acute stress-induced hyperglycemia and subsequent development of fasting hyperglycemia and weight gain, particularly under high-fat diet conditions.
What the research says
1 studyStudy: Amygdala–liver signalling orchestrates glycaemic responses to stress
When mice are stressed over and over, a brain circuit that normally boosts blood sugar during stress stops working right, leading to high blood sugar even when they’re not stressed — just like the claim says.
