The Claim
In rats undergoing semistarvation and refeeding, core body temperature remains reduced during weight regain at thermoneutral ambient temperature (29°C), indicating that this thermoregulatory adaptation is not driven by cold-induced thermogenesis and reflects a centrally regulated metabolic shift.
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 rats lose weight through food restriction and then regain it, their body temperature stays lower than normal even in a warm environment, showing that this change is not caused by cold exposure but by a central metabolic adjustment.

In rats undergoing semistarvation and refeeding, the reduction in core body temperature persists during weight regain even at thermoneutral ambient temperature (29°C), indicating that this thermoregulatory adaptation is not driven by cold-induced thermogenesis but may reflect a centrally regulated metabolic shift.
After losing weight, the brain lowers the body's target temperature, causing the body to run cooler. This reduces the energy needed to stay warm, so the extra calories from eating more go straight into storing fat instead of being burned as heat.
What the research says
1 studyEven when rats are kept warm enough that they don’t need to burn extra energy to stay warm, their body temperature stays lower than normal after losing weight — showing this isn’t just a reaction to cold, but a deeper change in how their body uses energy.
