The Claim

Long-term calorie restriction prevents the age-related decline in physical activity in rhesus monkeys, as demonstrated by stable accelerometer-measured activity levels over 18 years compared to a 30–40% decline in control animals.

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

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Supports

Challenges
0score

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

Monkeys that eat fewer calories over many years stay more active as they age, while monkeys that eat normally become much less active over time.

See the scientific wording

In rhesus monkeys, long-term calorie restriction prevents the age-related decline in physical activity observed in control animals, as evidenced by stable accelerometer counts over 18 years in CR monkeys versus a 30–40% decline in controls.

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 fewer calories stayed just as active as they got older, while monkeys eating normally became much less active. So, eating less helped them keep moving longer.
