Cassidy Duffield

Macro Nutrition Coaching Online or in Midvale, UT

I was a competitive gymnast for 10 years. After that I was a globo gym rat until I discovered CrossFit! I competed at the South CrossFit regional with a team in 2013, 2014, 2015, and as an individual in 2016. I’m also a competitive 69 kg weightlifter and won my first National meet, making me the National Champion in 2014, and 4th in the country 2015 after coming back from an injury. Since then I’ve focused on competing and training as an individual for CrossFit. I coach CrossFit and am the head barbell coach out of SLC CrossFit in Utah.

What were you doing before you started counting macros?

Mostly eating Paleo and “clean”. Definitely undereating!

How has flexible dieting changed your life?

As an athlete it has greatly improved my recovery and performance. It’s a lifestyle you can maintain, not just a fad diet where you starve yourself and can’t maintain it for longer than a few weeks. Focusing and finding things that fit your lifestyle and goals is truly satisfying – and it works! Exercising and eating for your own goals and health are the two things that you constantly control, and I love the satisfaction of knowing that no matter how crazy the day gets or things that happen in life, you can still control what you eat and don’t eat.

What got you involved in the nutrition world and why did you become a coach?

I started working with Jason and finally discovered how to have a positive relationship with food. When that happened, it made me realize I wanted to help others reach their goals whether it be their performance or aesthetic goals.

What is it you love most about helping people?

I love the moment when it clicks with clients – when they realize that it’s not a diet, and it’s something that anyone can do with just a little effort.

Best success story from client relationship:

I just recently helped a client cut from a 58 kg lifter to a 53 kg for a state meet. She was nervous from tough cuts before and skeptical about all the food I was still having her eat weeks out from the meet. She was training more, feeling stronger, recovering great, AND getting leaner while in the process of her cut. She woke up the day of and was pleasantly surprised to weigh in at 52.6, and set some new state records in her weight class!

How do you motivate and inspire people?

I use positivity! I’ve been in the same place before. It’s hard to address and discuss lifestyle changes that need to happen for most people. For clients struggling with self-image issues it’s important for me to help them discover that they aren’t broken and find a way to create a healthy relationship with food and lifestyle.
