Progesterone can influence metabolism and body weight in complex ways. It may mildly increase appetite and promote fluid retention, which can hinder weight loss. On the other hand, some evidence suggests progesterone improves insulin sensitivity, potentially supporting metabolic health. Individual responses vary greatly depending on dosage, route of administration (oral, transdermal, vaginal), and baseline hormone levels. During weight loss while on progesterone therapy, ensure adequate protein intake and regular exercise to preserve muscle mass. Importantly, progesterone is not a weight-loss drug. The evidence is mostly mechanistic and observational; controlled trials on progesterone for weight loss are lacking. Always consult a specialist before making changes to hormone therapy or diet.
