The Claim

Long-term moderate calorie restriction in rhesus monkeys leads to a significantly lower sleeping metabolic rate (by 11–19%) compared to control animals, even after adjusting for fat-free mass, indicating a persistent metabolic adaptation that reduces resting energy expenditure.

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.

How it works
1 study reviewed
In plain English

Monkeys that ate less for many years burn fewer calories while sleeping, even when you account for how much muscle they have, as if their bodies learned to use less energy just to stay alive.

See the scientific wording

In rhesus monkeys subjected to long-term (13–18 years) moderate calorie restriction, sleeping metabolic rate is significantly lower (by 11–19%) compared to control animals, even after adjusting for fat-free mass, suggesting a persistent metabolic adaptation that reduces energy expenditure at rest.

What the research says

1 study
  1. Study: Long-term calorie restriction decreases metabolic cost of movement and prevents decrease of physical activity during aging in the rhesus monkeys

    Monkeys that ate less for many years burned fewer calories while sleeping, even though they were more active during the day. This means their bodies adapted to use less energy just to stay alive at rest.
