The Claim
In Ames dwarf mice, caloric restriction (30% reduction in food intake) is associated with a 33% increase in survival rate at 2.25 years compared to ad libitum-fed controls, with 87% of caloric-restricted mice alive versus 54% of ad libitum-fed mice.
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.
Ames dwarf mice that eat 30% less food than normal have an 87% survival rate at 2.25 years, while those that eat without restriction have a 54% survival rate at the same age.
See the scientific wording
In Ames dwarf mice, caloric restriction (30% reduction in food intake) is associated with a 33% increase in survival rate at 2.25 years compared to ad libitum-fed controls, with 87% of CR dwarf mice alive versus 54% of AL dwarf mice, suggesting that reduced calorie intake may further extend lifespan in this genetically modified mouse model with hormonal deficiencies.
When these mice eat less food, their bodies produce less insulin and IGF-1, which slows down cell growth and repair processes. This reduces damage from energy use, lowers body temperature, and keeps the body running more efficiently. The mice also move more, which helps maintain muscle and brain function. Together, these changes delay aging and let more mice live longer.

1 studyStudy: Studies of aging in ames dwarf mice: Effects of caloric restriction
When scientists fed genetically weak mice 30% less food, more of them lived to 2.25 years than those fed normally — showing that eating less helped them live longer.
