Meet Lindsey
Hi, I'm Lindsey Zirker, a registered dietitian, kidney disease expert, and biochemical pathway explorer passionate about making health information easier to understand and accessible. I believe that when people understand the "why" behind nutrition and health recommendations, they can make more confident, informed decisions for themselves and those they care for.
What is Lindsey Zirker Nutrition Consulting?
What is Lindsey Zirker Nutrition Consulting?
Lindsey Zirker Nutrition Consulting is a virtual nutrition education and consulting business based in Idaho. I created this space because I wanted to help more people understand if and how nutrition plays a role in their health journey. I also LOVE teaching and sharing what I learn about nutrition- so I wanted a way to share what I learn with other health professionals too. I created resources that are available online and are enjoyed at their own pace, making it easy for individuals and healthcare professionals to learn from anywhere.

My Philosophy
My Philosophy
When you can find research to back up almost any opinion (and when everyone has an opinon) figuring out how, when or if nutrition recommendations apply to you (or to a patient), can feel overwhelming.
My goal isn't to tell you what to think—it's to help you understand how to think critically about nutrition and health. Through evidence-based education, practical tools, and clear explanations, I hope to make complex topics more approachable so you can confidently apply what you learn.
Why courses and ditigal products?
Throughout my career, I've worked with individuals navigating complex health conditions and have also spent years learning from and mentoring healthcare professionals. One thing became clear: improving health literacy has the potential to reach far beyond a single consultation. By creating accessible educational resources, I hope to equip more people with the knowledge they need to ask informed questions, understand their options, and actively participate in their healthcare.

Beyond work
Beyond work
When I'm not eyeball and elbow deep in journal articles, 50 open tabs, food lists, and biochemical pathways I enjoy reading historical fiction, playing strategy board games, and birdwatching / photography with my husband. I love hamburgers, strawberries, and dark chocolate.
In 2014, I was diagnosed with Hashimotos Disease while I was in graduate school. Before this I had the most boring health history possible, now it seems rather complicated. This ongoing and challenging experience has given me an unwanted, but valuable perspective of what living with chronic disease is like. I draw on these daily experiences to hopefully help me provide more insightful and practical knowledge and resources for you.
