Effects of high and low BMI on fertility

I'm thrilled to welcome Dr. Meredith Provost to The Egg Whisperer Show for an essential conversation about weight, exercise, and fertility. Dr. Provost brings an incredible background to this discussion: she's a reproductive endocrinologist at Indiana Fertility Institute with degrees from NC State, McMaster University, and a PhD from Cambridge in the history and philosophy of science. As a former Division I volleyball player and athlete herself, she uniquely understands both the science and the practical realities of maintaining health while trying to conceive. Her approach is refreshingly balanced and evidence-based, making her the perfect expert to tackle these often-confusing topics. Read the full show notes on Dr. Aimee's website In this episode, we dive deep into how weight impacts fertility for both women and men, exploring the hormonal mechanisms behind these connections. Dr. Provost shares her compassionate, non-restrictive approach to helping patients optimize their health without extreme measures or body shaming. We discuss realistic dietary recommendations, the role of BMI in fertility outcomes, and what exercise is safe during different stages of fertility treatment, from IUI cycles to egg freezing, IVF, and early pregnancy. Her philosophy of "fertility is a marathon, not a race" resonates throughout our conversation, offering hope and practical guidance for anyone on their fertility journey. In this episode, we cover:

• How weight affects the communication between your brain and ovaries, impacting ovulation
• The difference between how higher and lower BMI affects fertility in women versus men
• Why eating "real food" matters more than following restrictive fad diets
• Exercise guidelines during IUI, IVF, egg freezing, embryo transfer, and early pregnancy
• The truth about BMI goals and why Dr. Provost doesn't restrict treatment based on weight alone
• How to create sustainable lifestyle changes with accountability partners
• Why you shouldn't eliminate all the healthy coping mechanisms (like exercise) when trying to conceive
