Kristen's Story - sitting in a car during culinary school

Hi, there I’m Kristen, a Registered sports dietitian, certified personal trainer, and owner of Elite Nutrition & Performance! I created ENP several years ago while working at the University of South Carolina as a campus dietitian. During my stent there, many people outside of USC asked me if I could help them with their diet and training. Anything from training for a competition to helping them overcome an eating disorder. Back when I was studying for my undergraduate degree at the University of Maryland, I knew that I wanted to start my own business helping people live healthier active lives. However, it wasn’t until I got to Columbia that I realized there was a great need for someone to teach athletes and active individuals how to use food properly to fuel their bodies. That’s when ENP was born!

I’ve been an athlete most of my life…most. I was a dancer for over a decade (mostly acrobatics), played basketball and soccer, and ultimately ended up a competitive swimmer for a local team. Yes, I was one of those people who could eat anything and everything and not gain an ounce…up until I graduated high school that is. This is where the story goes downhill. I started my college career by going to Johnson & Wales University to study culinary arts. I was cooking and eating gourmet food five days a week and no longer exercising 2 hours a day. As you can imagine, the weight came flooding on.

I was completely lost on what to do. I knew that I wanted to lose weight but I had no idea how. I didn’t know what the difference was between a calorie and a gram of fat. I didn’t know what role of carbs or protein played in my diet. I knew nothing about nutrient timing. Instead, I did what was easiest and started taking diet pills. After suffering through extreme shakiness and feeling anxious, I lost 30 lbs only to realize these things were killing people! I quickly threw them out and almost instantly regained the 30 lbs. Now what? I did what was the next easiest thing…starve! That summer I returned from school and barely ate, losing 30 lbs in a matter of 2 ½ months. What started as a benign attempt to lose weight quickly spiraled out of control into an eating disorder that lasted over 3 years.

I left culinary school to focus on my passion, nutrition. I pursued a degree in dietetics from the University of Maryland all while struggling with my own nutrition issues. I’ll spare you all the gory details but these “issues” ranged from anorexia, over-exercising, binge eating and unsuccessfully attempting to purge. I had a horrible relationship with food and my body and struggled with body dysmorphia. After joining a group on campus called S.E.E.D.S (Students Educating on Eating Disorders), I realized I wasn’t the only one with this problem and wanted to get better.

I started reading every self-help book I could and nutrition book (written by registered dietitians, of course) I could. Between school and these books, I learned the basics of nutrition and started to put them into practice for myself. I learned how to eat mindfully and actually listen to my body. I ate when I was hungry, what I was hungry for, and stopped when I was full. I tried to follow a workout routine rather than exercising in response to eating. I even got rid of as many “triggers” to my disorder as I could, including fitness magazines. I did everything I could to set myself up for success.

After graduating from the University of Maryland with my B.S. in dietetics, I got certified through the American Council on Exercise as a personal trainer. That’s the time when I started to get interested in triathlons. I had a swimming background and cycled a lot with my dad so I figured adding in a run wouldn’t be too hard. I was always interested in sports nutrition due to my athletic background. However, training for and competing in triathlons made me realize just how important proper nutrition and hydration are in sports performance. I started reading, interning with sports dietitians, and attending as many sports nutrition conferences as I could.  That’s when I learned how to put together sports nutrition plans for endurance athletes that are as specific as how many grams of carbs to eat per minute!

Kristen's Story - Bodybuilding competition

After moving to SC, I started to shift my focus from endurance training to more weight training. I’ve always loved to lift weights and knew that I put on muscle easily. After loosely joking about competing in a body-building competition for years, I was encouraged by my husband and my co-worker, Sam, to finally sign up. After 8 physically and mentally demanding months, I finally competed in the figure division and was awarded 3rd place.

While training I learned a lot about myself, how the body responds to training adaptations and nutrition firsthand…far more than any textbook could have taught me! I also accomplished something that I always wanted to do but never thought I would. This was way more than just stepping out on stage; I was finally able to prove to myself that I had totally separated myself from my eating disorder over the years. I was able to follow through with an intensive nutrition and training plan. I was able to balance eating to fuel my working body yet eat foods I enjoyed that still fit into my plan.

To say that my life surrounding my relationship with food, exercise, and my body has been a rocky road is an understatement. It took several years, setbacks, and trying again to get where I am today. It’s funny to hear my clients say, “you must only eat healthy food “or think that I’ve been this way my entire life. I tell them that all of this has been a process and it’s totally possible for everyone to live a happy, healthy, and properly fueled active life!
