Profile & approach


Joey Simsen
I work with people on the psychology of food choices and sustainable behavior change
I spent years doing the right things with my health and still feeling like something was off. It wasn't until I started understanding the upstream causes of my energy, mood, and food patterns that things finally shifted.
I'm a certified health and lifestyle coach helping health-minded adults build lasting energy, focus, and a body that actually reflects the effort they've been putting in. Most people trying to get healthy are fighting an uphill battle by trying to use willpower and forcing themselves to eat better or go to the gym. The problem with that is: Willpower runs out.
My coaching focuses on what actually works:
- Resetting your nutrient balance: Most people have some nutrient deficiencies these days. Tackling those can deliver massive improvements
- Rebuilding your relationship with food: No calorie counting or restrictive diets, just deep awareness and lasting change
- Adding in movement: Integrating short workouts and recovery practices that deliver results in as little as 20 minutes per week
- Upgrading your habits and mindset to support high performance without burnout
If you're done with guesswork and ready to perform at your best, I’d love to support your journey.

Many people eat well and train hard yet still struggle because foundational nutritional imbalances go unseen. Traditional bloodwork often appears "normal" yet misses the deep biomarkers that truly matter.
Low Energy
Struggling to get through the day despite adequate sleep
Brain Fog
Difficulty concentrating and mental clarity issues

Taking longer to bounce back from workouts
Unexplained Issues
Health problems without clear answers

From the panel database
Nutrition test biomarkers
Nutrition testing shows what routine diagnostic labs often miss. Standard medical panels are designed to detect disease risk, but they can look normal while nutrient status, fatty-acid balance, and amino-acid availability still limit your energy, recovery, mood, sleep quality, and long-term performance. This panel is built for optimization: it measures the nutritional markers you can act on with targeted food, supplement, and lifestyle changes.
40 (36+4) markers across 9 categories.
Deliverables
Comprehensive, informative, and beautiful reports
Three polished PDFs—meal plan, Western Lifestyle Index, and biomarker analysis—translate your markers into clear, shareable documents you can revisit anytime and discuss in consultation.

Beyond routine bloodwork
What this program covers
Standard labs mostly screen cardiometabolic risk: lipids, glucose, and a few organ checks. Those are essential, yet they can sit in range while micronutrient status, fatty-acid balance, and amino-acid availability remain unseen, even though they underpin steady energy, recovery, sleep, mood, and quieting low-grade inflammation.
This panel measures vitamins, minerals, fatty acids, amino acids, and related categories in the context of how you eat and live. These values are essential for recovery, performance, and energy metabolism that can be directly influenced through nutrition and lifestyle interventions.
In addition, you get immediately actionable reports and information that actually matter to your day-to-day life. Optimal nutrition is essential for a longer life.
Analysis
Western Lifestyle Index (WLI)
The Western Lifestyle Index (WLI) quantifies the impact of diet, sleep, and stress on your biomarkers. Lower scores indicate healthier alignment; higher scores show influence from processed foods, poor sleep, and chronic stress.
Is your body impacted by the Western Lifestyle?
Legend
Why the Western Lifestyle Index matters
Quantified lifestyle impact
Impact points represent deviation from optimal biomarker ranges across diet, sleep, and stress-related markers. Lower points mean better health alignment.
Multi-factor analysis
Comprehensive assessment of how Western dietary patterns, sleep quality, and stress management affect your cellular health and performance.
Actionable insights
Identifies specific lifestyle factors affecting your biomarkers, enabling targeted interventions for improved health outcomes.
