The Claim

Body composition changes explain the association between suppressed basal metabolic rate and reduced body temperature during calorie restriction in mice, as no significant link remains when organ-specific models are used for prediction.

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.

How it works
1 study reviewed
In plain English

During calorie restriction in mice, changes in body composition account for the drop in metabolic rate and body temperature, and these effects are not due to a separate reduction in metabolic function when organ-specific models are applied.

See the scientific wording

The apparent association between suppressed basal metabolic rate and reduced body temperature during calorie restriction in mice is explained by body composition changes, not by independent metabolic downregulation, as no significant link remains when organ-specific models are used for prediction.

Why this might work

When food intake drops, organs shrink in size, which directly lowers how much energy the body uses and how much heat it produces. Once the smaller size of the organs is accounted for, there is no extra drop in energy use or body temperature beyond what the size change explains.

    When mice eat less, their organs get smaller, and that’s why they burn less energy and their body temperature drops—not because their cells slow down on their own. The study shows that once you account for the smaller organs, there’s no extra energy saving happening.
