Have you ever wondered how to look lean without compromising your endurance as a runner? Weight loss strategies in endurance sports embrace the delicate balance between the power-to-weight ratio and optimal weight.
Recent Australian statistics reveal that many female athletes actively seek effective weight management strategies to enhance their performance. With 67% of runners expressing concerns about weight impacting their performance and 23% battling bloating and digestive issues, there's a clear need for tailored solutions that prioritise health and performance for endurance runners.
Embarking on a weight loss journey as an endurance runner requires a careful and evidence-based approach. Safe weight loss is not just about shedding kilograms rapidly; it's about achieving a sustainable balance that supports optimal performance and overall well-being. Based on recent medical research and expert guidance, here are guidelines on what safe weight loss looks like over time:
Aim for gradual weight loss, typically around 0.5-1 kilogram weekly. This allows for a more sustainable and manageable approach, reducing the risk of negative impacts on performance and health.
Recognise that optimal weight differs for everyone. As the Journal of Sports Sciences (2021) highlights, a personalised assessment is crucial to understanding your body's unique needs and determining a realistic weight loss goal. Weight loss depends on many factors, including age, genetics, activity levels, nutrition, hormones, body type, muscle mass and state of health.
Focus on losing fat while preserving muscle mass. The International Journal of Sports Nutrition and Exercise Metabolism (2019) emphasises the importance of maintaining strength and power during weight loss, which is crucial for endurance athletes.
Implement gradual changes to your nutrition. The British Journal of Sports Medicine (2020) recommends a steady approach to weight loss to avoid negative impacts on performance, health, and hormonal balance. Gradual changes also allow the athlete to incorporate necessary changes into their lifestyle, making them easier to adhere to and more sustainable.
Embrace a holistic approach that goes beyond the numbers on the scale. Consider other factors such as digestive health, hormonal health and stress. The Journal of the International Society of Sports Nutrition (2018) suggests these factors can impact training and competition experiences.
Seek guidance from a qualified sports nutritionist and health professional. Kate Smyth combines naturopathy, targeted sports nutrition, and female-friendly coaching techniques based on her experience and the latest research.
Monitor your progress regularly and make adjustments as needed. The Journal of Science and Medicine in Sport (2022) emphasises the role of ongoing nutrition optimisation in supporting endurance performance. Adjusting fuelling techniques, food volumes, and nutritional density helps to avoid issues such as REDs during a weight loss phase.
Pay attention to how your body responds to changes in nutrition and training. Consult a healthcare professional to adjust your plan if you experience any adverse effects or performance declines. Fuelling for performance is always better than restricting fuel for weight loss, which will likely impact performance.
Ensure proper hydration and nourishment. Weight loss should not compromise your body's essential needs, and maintaining proper hydration and nutrient intake is crucial for overall health. Hydration has been a popular topic. Read some of our recent blogs on the topic of hydration and electrolytes.
Acknowledge and celebrate non-scale victories, such as improved energy levels, better sleep, and enhanced overall well-being. These indicators are just as important as the numbers on the scale.
Remember, safe weight loss is a journey that requires patience, dedication, and a commitment to your overall health and performance. By following these guidelines and consulting with experts, you can achieve your weight loss goals while optimising your endurance journey.
Achieving weight loss as an endurance runner doesn't mean compromising your health or performance. At the Athlete Sanctuary, we're committed to helping you unlock your full potential through a holistic approach that addresses your unique needs.

Kate Smyth is a sports naturopath, nutritionist and female-centric running coach. She is the founder of the Athlete Sanctuary - a holistic healthcare clinic for athletes of all levels and sporting codes.
Kate has a thirst for knowledge, with two bachelor's and a master’s degree under her belt. She has been involved in sports for many decades and competed for Australia in the Commonwealth Games and Olympic Games marathons with a personal best time of 2 hours 28 minutes.
Kate’s path into high‑performance sport didn’t follow the traditional script. A late bloomer and recreational runner, she found her spark during the Sydney 2000 Olympics, watching her idols surge into the stadium. That moment ignited a commitment that would quietly and profoundly reshape the course of her life.
Eight years later, she realised her own Olympic dream, representing Australia in the women’s marathon at the 2008 Beijing Olympic Games.
Her running career spanned the Commonwealth Games, multiple Australian representative teams, and national‑level competition across cross‑country, track, and road racing. With a marathon personal best of 2:28, Kate was one of Australia’s all time fastest female marathoners.
But her journey was far from linear. Significant health challenges forced her to question conventional medicine, sports nutrition and traditional training models. What felt like setbacks at the time became turning points, pushing her to explore deeper, listen more closely to her body, and ultimately develop a more sustainable, female‑centred approach to performance.
These experiences now form the foundation of the work she shares with other women: how to train smarter, nourish deeply, honour physiology, and build resilience from the inside out.
She holds three degrees including a Masters and Bachelor of Health Science (Naturopathy). Kate is an accredited athletics coach with Athletics Australia and a member of NHAA.
Kate’s expertise is widely recognised, leading to regular invitations to speak on podcasts, at seminars, within industry education forums, and across corporate and women’s health initiatives.
