The Claim
In rats undergoing weight regain after semistarvation, persistent hypothermia occurs despite the return of uncoupling protein 1 expression in brown adipose tissue to baseline levels, indicating that changes in brown adipose tissue thermogenesis do not account for the reduction in core body temperature.
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.
In rats that regain weight after a period of severe food restriction, body temperature remains low even though the molecular mechanism in fat tissue responsible for heat production returns to normal levels.
See the scientific wording
In rats, the reduction in core body temperature during weight regain after semistarvation is not explained by changes in brown adipose tissue thermogenesis, as uncoupling protein 1 expression returns to baseline during refeeding despite persistent hypothermia.
After starvation, the brain lowers the body's target temperature and keeps it there even after eating normally again. This makes the body produce less heat, saving energy that gets stored as fat. The heat-producing fat tissue returns to normal, but the brain still keeps the temperature low, so the body stays cold.
What the research says
1 studyEven after rats eat normally again and regain weight, their body temperature stays lower than before — and it’s not because they’re eating less or moving less. This means something else in their body, not their heat-producing fat, is keeping them cold.
