I need a short article or brochure explaining insulin resistance to give to my son's school. It shouldn't start with an explanation of beta cells! It should explain the basic idea about the body still making enough insulin, but how cells don't respond well. It should explain that IR can lead to pre-diabetes, and it should explain that insulin resistance and pre-diabetes are not exact synonyms.
Everything good I've found so far is too long, e.g. https://www.niddk.nih.gov/health-information/diabetes/types/prediabetes-insulin-resistance
