About Matt

Hello, I’m Matt Knight, Naperville Nutritionist and a Registered Dietitian (RDN). This page provides more detail about who I am and how I got here.

I am licensed to practice nutrition in the state of Illinois. Also, I am a member of the Academy of Nutrition and Dietetics and the Dietetics in Functional Medicine practice group.

I bring a fairly unique background to my practice. Being a dietitian was not my first career choice coming out of college.

For eight years after graduating college in 2002 I worked as certified public accountant (CPA) with jobs in both accounting and finance. In 2010 I made a major life decision and choose to pursue a second career. I decided to follow my passion into a career in the world of nutrition and dietetics.

After resigning from my full time job on my birthday in June 2010, I never looked back.


I have earned two bachelor degrees, the first in Accounting and a second degree in Nutrition. My nutrition degree was earned at California State University, Long Beach in 2013. After graduating I completed a dietetic internship at Hines VA hospital in 2014.

Since the fall of 2014, I have been working full time as a registered dietitian and started a private practice in 2019.

Approach to Nutrition

My overall approach to nutrition, health, and healing involves helping others seek out and treat the root cause of disease using a “Food as Medicine” model of practice. I use these principles when I provide weight management counseling, nutrition therapy, and education to individuals and groups.

I work with many health related conditions including weight loss, diabetes, heart disease, and digestive disorders. In addition, I teach classes about anti-inflammatory dieting and improving your diet.

I believe the basis of a healthy diet involves choosing foods that are raised ethically and locally grown. The World Health Organization (WHO) defines health as “a state of complete physical, mental and social well-being and not merely the absence of disease.”

We need to move beyond that model and not just focus on absence of disease but true mental, physical and emotional health.

I believe that we all need to take a more proactive role in managing our own health. In order to do that, we need to incorporate more real, local foods into our diets. We know that it is really hard to change behaviors. However, the best thing we can do is keep it simple and make it easy to adopt new habits.

Creative Writing

My blog represents the creative side of my business. I enjoy providing education through writing. My goal is to translate the science of food and nutrition into easy to understand, simple and actionable steps that anyone can take to improve their health and well-being.

Personal Life

In my spare time you will most likely find me outside working in my garden, playing with my two crazy boys or reading a good book. I also enjoy watching college basketball, especially the NCAA tournament in March.

You will find me at the local farmers market every weekend during the summer and fall. I love to cook all the fresh fruits and vegetables I bring home each weekend.
