Using animals for research is commonplace around the world, even during ethically questionable experiments.
Calorie-restriction research frequently revolves around animal testing. Animals are protected in accordance to Australian code of Practice for the care and use of animals for scientific purposes.
These policies are enforced by the Animal Ethics Committee (AEC), composed of veterinarians and scientists.
In the case of researchers not abiding by the conduct, the AEC have the ability to terminate a project and charge offenders under relevant state legislation.
