Fuel your training and your busy life
Stop overthinking food
Show up to your next race with confidence
No Sweat Nutrition was founded by Sandra Kilmartin, a BC-based Registered Sports Dietitian and ultrarunner.
As an endurance athlete, Sandra knows firsthand how powerful nutrition can be — not only for performance, but for energy, recovery, and overall well-being. She also understands the all-too-common stories of undereating, fatigue, injury, and lost joy in sport.
What began as a solo practice has grown into a collaborative team of sports dietitians who share a common mission: To create a space where athletes can heal their relationship with food and fuel with confidence.
You've heard it all...take this supplement, carb load, eat more protein, gels give you diabetes, become fat adapted. It's exhausting.
We get it. You just want to fuel well, perform strong, and still have the energy for life outside of training.
We believe sports nutrition shouldn't feel like a full-time job.
We can help you:
• show up on race day with confidence in your fueling and hydration plan
• finally get to the bottom of gastrointestinal issues including “runners stomach”, constipation, Celiac disease, and Irritable Bowel Syndrome (IBS)
• correct iron deficiency and reclaim your energy
• recover from relative energy deficiency in sport (REDs) and start to feel like yourself again
• get your period back and recover from hypothalamic amenorrhea (HA)
• navigate disordered eating and recover from an eating disorder (no formal diagnosis required)
• eat well for injury recovery and rehabilitation
We support a wide range of athletes and active individuals across BC and Ontario, including:
• Endurance athletes: runners, cyclists, triathletes, ultrarunners, cross country/nordic skiers, and adventure racers
• Climbers, mountain bikers, swimmers, dancers, gymnasts, and team-sport athletes (rugby, soccer, hockey, etc.)
• Shift workers such as firefighters, police, paramedics, and healthcare professionals
• Child, youth, and adolescent athletes
