The Claim
Caloric restriction increases locomotor activity in aging mice compared to ad libitum feeding, regardless of genetic background.
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.
Aging mice that eat fewer calories move more than aging mice that eat without restriction, no matter their genetic makeup.
See the scientific wording
Caloric restriction increases locomotor activity in aging mice, with CR-fed mice showing significantly higher total activity than ad libitum-fed counterparts, regardless of genetic background, suggesting that reduced calorie intake is associated with sustained physical activity in late life.
Eating fewer calories lowers blood sugar and insulin levels, which reduces signals that promote growth and energy use. This causes the body to burn less energy at rest and stay cooler, while also making muscles and nerves work more efficiently. As a result, older animals move more because their bodies are under less stress and their movement systems stay sharper longer.
What the research says
1 studyStudy: Studies of aging in ames dwarf mice: Effects of caloric restriction
Mice that ate less food moved around more as they got older, whether they were regular mice or special small mice with a genetic mutation. This suggests eating less helps older mice stay more active.
