                                A 2019 systematic review and meta-analysis of human trials found that fasting regimens significantly reduced circulating IGF-1 levels. This evidence directly contradicts the misconception that **intermittent fasting increases IGF-1**, and instead points to the opposite effect, providing key insights into the body's hormonal response to fasting.
