Gonadal hormones have a complicated influence on appetite. Estradiol generally suppresses appetite, whereas progesterone opposes estradiol's action such that their combined presence represents a high-risk hormonal milieu for Binge Eating (BE). Testosterone is thought to be associated with increased BE in females but appears protective in males. In some reports, combination oral contraceptive (COC) use has been linked to greater BE-related appetitive processes (e.g., food intake). Now, we have 2 recent, back-to-back publications (June 2026 in JAMA Network Open, and July 2026 in Appetite) that have examined the relationship of hormonal contraception on binge eating behavior. These found seemingly opposing conclusions. Listen in for details.
