The following are not considered "interventions" for our purposes:
• Substances offered in ingestive preference tests
• Glucose tolerance tests and similar
• Where a perturbation is done as necessary preparation for a phenotyping procedure but it's not the primary focus of the study question or study design, such as fasting period before blood studies, pain inducers in nociception tests, or preliminary surgery to induce a certain condition.
