Sofia Medina is a public health researcher and women's health writer whose work sits at the intersection of hormonal biology, metabolic disease, and the lived experiences of women navigating weight management at every life stage. She earned her Master of Public Health in Maternal & Child Health from Emory University's Rollins School of Public Health, where her thesis research examined the hormonal contributors to weight gain in women with polycystic ovary syndrome (PCOS) — specifically how insulin resistance, androgen excess, and chronic inflammation create compounding metabolic challenges that standard weight loss guidance rarely addresses. That research sparked a career-long commitment to centering women's physiology in conversations about obesity treatment, a perspective she now brings to every article she writes for Losing Weight RX.
Before transitioning to health content, Sofia spent several years in women's health program evaluation at community health organizations across the Southeast. She designed outcome tracking frameworks for prenatal nutrition programs, led focus groups with postpartum women struggling with weight retention, and co-authored program reports that influenced how local health departments allocated maternal health funding. It was during this work — sitting across the table from women who had been told to "just eat less" while battling undiagnosed PCOS or early perimenopause — that she recognized how badly the weight management space needed writers who understood female endocrinology from both a clinical and a human level.
Sofia now writes exclusively about GLP-1 receptor agonists, metabolic wellness, and hormonal weight regulation. Her articles focus on the questions most weight loss content ignores: How do semaglutide and tirzepatide interact with the hormonal fluctuations of a menstrual cycle? What does the evidence actually say about GLP-1 medications and PCOS-related insulin resistance? What should a woman in perimenopause know before starting these medications? She draws on peer-reviewed research, clinical guidelines, and her years of direct engagement with women's health communities to write content that is both scientifically rigorous and genuinely useful to the women reading it.
