The Claim
The beneficial effects of 15% and 35% caloric restriction on reproductive parameters in 12-month-old male Wistar rats are not maintained after 12 months of intervention, with only 33% of caloric restriction rats showing male sexual behavior compared to 100% at 6 months.
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.
Researchers found that when they put middle-aged male rats on a diet with 15% or 35% fewer calories, it helped their reproductive health at first. But after a year on the diet, these benefits went away, and only one-third of the dieting rats still showed normal mating behavior compared to all of them at six months.
See the scientific wording
The beneficial effects of 15% and 35% caloric restriction on reproductive parameters in 12-month-old male Wistar rats are not maintained after 12 months of intervention, with only 33% of CR rats showing male sexual behavior compared to 100% at 6 months.
What the research says
1 studyStudy: Effect of Chronic Moderate Caloric Restriction on the Reproductive Function in Aged Male Wistar Rats
The study found that cutting calories helped older rats' reproductive health for a while, but after a year, it didn't work as well anymore, which matches what the claim says.
