The moment you decide to show up publicly, you open the door to opinions from people who would never say those things to your face. Dominique Sachse, journalist, author, and content creator who has lived her life on camera for over three decades, gets honest about what it costs to put yourself out there, why online cruelty is a psychology problem more than a content problem, and how “Teflon Dom” developed the thick skin to let none of it redirect her.

Only nine scientists were asked to advise on the 2025 Dietary Guidelines for Americans, and Dr. Tom Brenna was one of them. In this conversation, he pulls back the curtain on how dietary guidelines are actually made, why the process has never been the same twice, and what it was like to watch a decades-old saturated fat recommendation get carried forward despite a lack of evidence supporting it at the level of total mortality. This is the dietary guidelines conversation the internet has been missing: straight from someone who was actually in the room.

In a world flooded with conflicting health advice, how do you actually figure out what’s true? Dr. David Allison, one of the most rigorous scientific minds in obesity and nutrition research, shared the exact framework he uses to evaluate evidence, from peer-reviewed trials to podcast recommendations to AI-generated summaries. He explains the difference between trusting science as a process and trusting individual studies, why most nutrition epidemiology functions more like advertising than research, and how ordinary people can build a reliable filter for health claims without a PhD.
