The Claim
Calorie restriction in female mice housed at 22°C increases hypothalamic production of nitric oxide via the citrulline-nitric oxide cycle, and pharmacological inhibition of nitric oxide synthase prevents the decrease in core body temperature that accompanies calorie restriction, demonstrating that nitric oxide is a necessary mediator of calorie restriction-induced hypothermia.
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 female mice kept at 22°C, reducing calorie intake raises nitric oxide levels in the hypothalamus through the citrulline-nitric oxide cycle, and blocking nitric oxide production stops the drop in body temperature that normally occurs with reduced calorie intake.
See the scientific wording
Calorie restriction in female mice housed at 22°C increases hypothalamic production of nitric oxide via the citrulline-nitric oxide cycle, and pharmacological inhibition of nitric oxide synthase blocks the associated drop in core body temperature, indicating that nitric oxide is a necessary mediator of CR-induced hypothermia.
When female mice eat less in a cool room, their brain uses a specific chemical pathway to make more nitric oxide. This gas causes blood vessels near the skin to widen, letting heat escape and lowering body temperature. If this nitric oxide production is blocked, the body cannot cool down, even with less food.
What the research says
1 studyStudy: Metabolic adaptation to calorie restriction
When female mice eat less in a cool room, their brain makes more nitric oxide, which helps them get cooler. If scientists block nitric oxide production, the mice don’t get cooler—even if they eat less. So nitric oxide is needed for this cooling effect.
