We are a team of sports dietitians who share one common mission: To create a space where athletes can heal their relationship with food and fuel 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.

We are a virtual clinic that supports 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/eating disorders

-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

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.

Our approach is guided by three pillars:
1. Athlete-Centred: We build fueling plans that fit your goals, schedule, preferences, and sport.
2. Evidence-Based: We help you make sense of the endless stream of nutrition information by translating science into simple, actionable steps.
3. Weight-Neutral: We focus on health, athlete well-being, and performance — not weight or appearance.

Our team of registered sports dietitians brings together diverse athletic backgrounds — from track and ultramarathon running to climbing and rugby.
