Performance Nutritionist / Dietitian – Competitive Athlete & Tech Entrepreneur

We're looking for a specialized performance nutritionist or dietitian who can optimize nutrition for two equally demanding worlds: competitive ice hockey (16+ hours/week training) and running multiple international tech and e-commerce ventures at the highest level. This is not just a sports nutrition plan — it's a complete performance nutrition strategy for someone operating at full intensity both physically and mentally, every single day.

Freelancers only — no agencies. Ongoing engagement with regular check-ins and plan adjustments.

ABOUT ME
• 30-year-old serial tech entrepreneur running multiple international ventures
• Competitive ice hockey player — 16+ hours/week training and playing recreationally in Dutch leagues
• Diagnosed with ADHD — nutrition plays a key role in managing focus, energy regulation, and cognitive performance
• Two full-time demands — building companies requires sustained mental clarity, focus, and energy. Ice hockey requires explosive power, endurance, and fast recovery.
• Looking for someone who can optimize for both — not one at the expense of the other

WHAT I NEED

Athletic Performance Nutrition
• Personalized nutrition plan optimized for ice hockey performance
• Pre-game, during-game, and post-game nutrition protocols
• Training day vs. rest day nutrition cycling
• Macronutrient and micronutrient optimization for explosive sports
• Hydration strategy for high-intensity training
• Supplement guidance — what works, what doesn't
• Recovery nutrition — reducing inflammation, speeding up recovery between sessions
• Injury prevention and immune system support through nutrition

Cognitive & Entrepreneurial Performance Nutrition
• Nutrition for mental clarity, focus, and sustained energy throughout 10-14 hour work days
• ADHD-specific nutrition strategies — supporting focus, dopamine regulation, and impulse control through diet
• Blood sugar stability — avoiding spikes and crashes that worsen ADHD symptoms
• Managing energy levels — avoiding crashes, brain fog, and afternoon dips
• Nutrition strategies for high-pressure situations (investor pitches, negotiations, long work sprints)
• Gut-brain connection — optimizing gut health for mental performance
• Sleep optimization through nutrition
• Stress resilience and mood stability through diet
• Nutrition for decision-making and creative thinking under pressure

Integrated Performance
• Balancing athletic fueling and cognitive fueling — days with training + heavy work need both
• Periodization — adjusting nutrition across game days, training days, heavy work days, and rest days
• Travel nutrition — maintaining performance during business trips, jet lag, irregular schedules
• Long-term health, longevity, and sustainable high performance across both domains

Body Composition & Health
• Body composition optimization — lean muscle for hockey, not bulk
• Blood work analysis and adjustments based on biomarkers
• Long-term health monitoring and proactive adjustments

Ongoing Support
• Meal planning — practical, time-efficient meals (I'm busy)
• Grocery lists and meal prep guidance
• Regular check-ins and plan adjustments based on training load, travel, and work schedule
• Quick async support when plans change last minute

WHO YOU ARE
• Certified sports nutritionist or registered dietitian
• 5+ years experience working with competitive or elite athletes
• Understanding of cognitive performance nutrition — not just physical
• Evidence-based approach — science, not fads
• Practical mindset — plans that work in a busy, real-world lifestyle
• Proactive — you check in, adjust, and optimize continuously

Ideal:
• Experience with ice hockey players — professional leagues (NHL, KHL, SHL, DEL, Liiga, NL Eredivisie), national teams, or competitive club level
• Experience working with entrepreneurs, executives, or high-performers balancing sport and career
• Understanding of nutrition for both physical and cognitive peak performance
• Experience with ADHD and neurodivergent clients — understanding how nutrition impacts focus, dopamine, and executive function

Bonus:
• Experience with other elite winter sports or explosive team sports athletes
• Familiarity with Dutch/European food availability
• Experience with bloodwork interpretation and biomarker optimization
• Published research or speaking experience in sports or cognitive performance nutrition

HOW WE WORK
• Remote — video calls, messaging, async support
• Regular check-ins (weekly or bi-weekly)
• Flexible — adapt plans based on training schedule, travel, and work demands
• Long-term relationship — this is not a one-time meal plan
