The Claim

In male Sprague-Dawley rats subjected to semistarvation followed by controlled refeeding, a persistent reduction in 24-hour core body temperature by 0.27°C on average is associated with preferential fat mass regain, independent of locomotor activity or ambient temperature, and this association suggests that a lowered thermoregulatory set point contributes to metabolic efficiency during weight recovery.

Source: Low 24-hour core body temperature as a thrifty metabolic trait driving catch-up fat during weight regain after caloric restriction.

How it works
1 study reviewed
In plain English

In male Sprague-Dawley rats recovering from food restriction, a consistent drop in core body temperature by 0.27°C is linked to greater fat regain compared to lean mass, even when activity levels and room temperature are held constant, indicating that a lower internal temperature setting may increase metabolic efficiency during weight recovery.

Why this might work

After losing weight from eating less, the brain lowers the body's target temperature, causing the body to run cooler. This cooler temperature saves energy that would have been used to stay warm. The saved energy is used to make more fat, even when the animal eats the same amount as before and moves normally.

  1. Study: Low 24-hour core body temperature as a thrifty metabolic trait driving catch-up fat during weight regain after caloric restriction.

    When rats lose weight by eating less and then eat normally again, their body temperature stays a little lower than before—even though they move the same and eat the same amount. This lower temperature helps them save energy, which makes them put on fat faster.
