A Low Glycemic Index and Glycemic Load Diet Decreases Insulin-like Growth Factor-1 among Adults with Moderate and Severe Acne: AÂ Short-Duration, 2-Week Randomized Controlled Trial

In this study, a low GI and GL diet decreased IGF-1 concentrations, a well-established factor in acne pathogenesis. Further research of a longer duration should examine whether a low GI and GL diet would result in a clinically meaningful difference in IGF-1 concentrations leading to a reduction in acne. This trial was registered at clinicaltrials.gov as NCT02913001.
