Background

Hi, I’m Josh Sisk, a Registered Dietitian who helps people build sustainable habits, improve their health, and reach performance goals through personalized, evidence-based nutrition coaching.

I specialize in:

- Weight management and sustainable fat loss

- Metabolic health, including blood sugar management and improving labs like A1c and cholesterol

- Performance nutrition for endurance, strength, and CrossFit athletes

- Meal planning and prep strategies that work in real life

Over the 3 years, I’ve helped more than 70 clients lose 20+ pounds and keep it off, supported 50+ clients in improving lab values like cholesterol and A1c, and guided over 100 individuals in building muscle and reducing fat—all through tailored, habit-based coaching.

I hold a Master’s in Dietetics from Marshall University and a Bachelor's in Nutrition from West Virginia University. My background includes performance nutrition roles at the University of Colorado-Boulder, CrossFit Omnia, and outpatient counseling – giving me a strong foundation in sports nutrition and behavior change.

My coaching philosophy is simple: knowledge is power. Together, we’ll map out a clear path to your goals, then break it into small, manageable steps. Each session builds on the last, with a focus on mastering habits that stick. I’m here to make complex nutrition simple—and help you feel confident in maintaining your results for life.

Clients often say they feel comfortable opening up with me and appreciate how I meet them where they’re at, offering weekly motivation and actionable steps that actually work.

Outside of sessions, you’ll find me trail running, cycling, weightlifting, or working on my side passion: roasting and selling specialty coffee.

Ready to take control of your health and build a plan that works for you? Let’s get started.
