KRISTIN DUYN

MScN

Kristin holds a Master of Science in Nutrition Degree from the National University of Natural Medicine in Portland, OR. Her approach to nutrition is evidence-based and integrates nutritional biochemistry with advanced clinical nutrition. Kristin’s education and clinical experience provides her with a solid foundation in holistic nutrition and skilled training in cooking, teaching, and nutritional counseling.

Kristin was drawn to nutrition through her own athletic pursuits. After being a multisport high school athlete she went on to compete in track and field at the University of Montana. After graduation, she moved to Portland, OR and began racing road marathons, mountain bikes, and road bikes. Some of her athletic achievements include:

Road Marathon PR: 2:46 (2012 Olympic B Standard Qualifier)
Half Marathon PR: 1:17
1st Place Tour of Gila Road Bike Race
1st Place USA Mountain Bike National Championships Category 1

As an athlete, Kristin understands the importance of proper fueling and how critical nutrition is to support the demands of training, racing, and recovering. The combination of years of personal experience as an endurance athlete and scientific expertise in human biochemistry and functional nutrition allows her to approach nutrition and coaching from a unique perspective.

Kristin is an active member of the International Society of Sports Medicine (CISSN). She is also a USATF Level 1 Certified Running Coach, a Training Peaks Level 1 Certified Coach, and coaches cross country and track at the high school level.

Kristin enjoys working with endurance athletes at all levels and specializes in helping clients maintain optimal hormonal balance. A disruption of hormones can impair short term performance gains, lead to injury and lack of recovery, and cause long term health issues. Years of personal experience with this issue is what motivated Kristin to pursue an education in nutritional biochemistry and she is passionate about sharing her knowledge with other athletes looking to optimize performance and longevity in sport.

WHAT KRISTIN’S CLIENTS SAY

Kristin has helped me during various phases of life and training! From helping me optimize my nutrition to perform better (I began hitting paces in workouts I’ve never hit before – all while feeling ENERGIZED), she leaned into my love of cooking and gave me a variety of recipes to try, worked with my family’s ever-changing schedule, and even supported my family through changing over to a gluten free household after finding out my husband has celiac disease (unexpected). Grateful for her support, and making me feel so empowered about a topic that used to feel intimidating!

Toni K. – Runner, Pennsylvania

I want to THANK YOU for everything! Your support through my time of dealing with breast cancer and ALL of the suggestions and guidelines you’ve provided in these past 3 months have been LIFE CHANGING, for sure!

N.C.

I started working with Kristin in July following a prolonged period of time with lack of energy, not enjoying my training or not hitting the numbers in my training sessions. Kristin has made it easy for me to know how much to eat before and after varying lengths of workout. Thankfully, my energy levels are back to where I want them to be and I am enjoying my training better knowing I am fueling my body properly. I finally feel like I am eating like an athlete.

Anita S. – Triathlete, United Kingdom

Kristin has been phenomenal in helping me understand my big picture needs and how to make long-term better health choices as well as short-term athletic gains. As a backcountry mountain bike guide, craftsman, skier, cyclist, and runner, her program has helped me target better performance and most notably recovery in each realm of sport. I feel empowered to guide my health in proactive ways that I didn’t feel was possible before. I’ve learned to slow down a little, focus on the process of eating well, planning and recovery, and have been feeling more rested and better balanced as a result.

Paul L. – Multi-sport endurance athlete (biking, skiing, running), Oregon, USA

I mentioned the other day that I was looking forward to weighing in this morning, not in hopes of some crazy weight loss but in breaking through a bit of a plateau. Well, I have broken through it…..I’m now at 179 lbs, and I started out 4 years ago at 285. I’ve gotten close to the 100lb mark, but haven’t been able to break through. Now, with your help, I’ve broken through. Thank you again for your help and support. The meal plan approach has been a complete change for us, but is working.
