In this talk, the speaker emphasizes that most people neglect dietary fiber, which is essential for a diverse gut microbiome. She explains that a healthy gut, nourished by fiber and a variety of fruits and vegetables, is foundational to hormonal balance, insulin resistance, inflammation, and ultimately fertility. The speaker notes that many fertility doctors overlook gut health, permeability, and microbiome considerations, despite their critical role in metabolizing estrogen and other hormones. She encourages patients to focus on gut health as a primary step toward improving reproductive outcomes.

The number one thing that most people are not doing is going to be fiber. Having more fiber in your diet, higher variety of fruits and vegetables. Your gut is so integral to your hormonal health and your levels of insulin resistance, your levels of inflammation, how your hormones are even going to function. Yet so few fertility doctors are even talking about gut health or gut permeability and your gut microbiome. But it's the first layer of exposure. When I try to break this down for patients, because there's always nutritional pushback or fear or hesitation because it feels really scary to sometimes change our food. I always say, look inside your gut. You've got your gut microbiome. They do so many incredible things for your health. They even, you know, help metabolize estrogen and other hormones, but they are fed only by fiber.
