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:
- take this supplement
- carb load
- eat more protein
- gels give you diabetes
- become fat-adapted
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.
Our approach helps you cut through the noise and focus on what actually matters for your sport, your body, and your goals — no extremes, no guilt, just clarity and confidence. Whether you're training for your first a 5K, a 100-mile ultra, or just want the energy to chase your kids around after training, we’ll help you stop overthinking food and dial in a nutrition strategy that actually works.
Athlete-Centred:
We build fueling plans that fit your goals, schedule, preferences, and sport.Evidence-Based:
We help you make sense of the endless stream of nutrition information by translating science into simple, actionable steps.Weight-Neutral:
We focus on health, athlete well-being, and performance — not weight or appearance.
We support a wide range of athletes and active individuals across BC and Ontario, including:
- Athletes navigating relative iron deficiency, energy deficiency in sport (REDs/RED-S), hypothalamic amenorrhea (HA), and disordered eating
- 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 including college/varsity
