How Nutrition Shapes Mental Health with Lindsay Keosayian and Jillian Maher
What if the key to mental clarity and resilience isn’t in your to-do list, but on your plate?
When integrative nutrition health coach Lindsay Keosayian and Properly Pressed founder Jillian Maher began rethinking their relationship with food, they discovered that nutrition could be a powerful lever for improving mood, focus, and overall well-being.
Many people know what it’s like to feel not quite themselves: less energy, less focus, less joy. For Lindsay and Jillian, those moments became turning points, prompting them to dig into the connection between what they ate and how they felt.
On this episode of Prevention Pioneers, they share how small nutrition adjustments can shift not just physical health but also mental resilience, and why the gut-brain connection is one of the most underrated levers for improving mood and focus.
Small Changes for Meaningful Results
For both women, nutrition and mental health are not just professional interests. Each has faced personal health challenges that led them to rethink their approach to food. For Lindsay, it was the frustration of not finding answers through traditional routes alone that led her to explore integrative nutrition alongside professional guidance, and slowly, things started to shift.
Jillian’s turning point was more abrupt. “I had no idea how to eat, and it caught up with me very quickly.” Making intentional choices about food and hydration changed not just how she felt physically, but how she showed up mentally.
Both experiences point to the same insight: you don’t need a perfect diet to feel a difference. Small, deliberate changes can be enough to start moving the needle.
Gut Health and Mental Health: The Overlooked Link
How does nutrition affect mental health? Lindsay points to the science behind the gut-brain connection. “We know that the gut and the brain are connected. And when our gut is off, usually our mood is off as well.”
Jillian adds that when food doesn’t sit well with her body, “I kind of lose a portion of myself because I believe that the gut is sending the signals to the mind…how could you be happy if you didn’t have what you needed to thrive, right?”
They emphasize that it’s not just about eating more vegetables or avoiding sugar. It’s about understanding how certain foods can quietly disrupt mental clarity and resilience, while others can help us feel more balanced and energized.
Moving Beyond All-or-Nothing
One of the biggest mental barriers Lindsay and Jillian see is the idea that healthy eating requires perfection. Many people feel pressure to completely overhaul their diets, but both guests encourage a different mindset. Lindsay reminds us, “It’s really important for people to start small. Pick one thing that they want to focus on.”
Instead of striving for perfection, they suggest tracking what you eat and how you feel, and focusing on progress. “When you start to track all of that, you can connect the dots to see what foods made you feel really good… the momentum really starts to pick up, and when you feel good, it makes it easier to continue on that path.”
