The Claim
Ames dwarf mice consume more food per gram of body weight than normal mice under ad libitum feeding conditions, and this increased intake occurs despite their extended lifespan, indicating that their longevity is not attributable to reduced caloric consumption but may be associated with altered metabolic efficiency.
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 eat more food relative to their body weight than normal mice, even when food is freely available, and their longer lifespan is not caused by eating less but may result from differences in how their bodies use energy.
See the scientific wording
Ames dwarf mice consume more food per gram of body weight than normal mice, even when fed ad libitum, suggesting that their extended lifespan is not due to voluntary caloric restriction but may involve altered metabolic efficiency.
A genetic mutation causes the pituitary gland to produce less growth hormone, which lowers the levels of a growth-related protein in the liver. This slows down the body's energy use and body temperature, reduces the rate at which cells divide and accumulate damage, and makes the body more efficient at using food for maintenance instead of growth. As a result, the animal eats more food per pound of body weight but ages slower and lives longer.

1 studyStudy: Studies of aging in ames dwarf mice: Effects of caloric restriction
Ames dwarf mice eat more food for their size than regular mice, yet they live longer—so their long life isn’t because they eat less, but because their bodies use energy better.
