Improve your quality of life

I haven’t always liked eating healthy and exercising! Until I was almost 21 years old I hated vegetables, loved sugar and drank soda! With a combination of changes to my diet and a bit of exercise, I was able to lose almost 10 kilos- and never gain it back! If you want to improve how you see yourself in the mirror, learn how to eat in alignment with your goals AND like your diet… let me help you achieve those goals!

The keys to reach your goals:

Exercise 0
Nutrition 0
Rest 0

A little more about me…

Hi…  I’m Gillian!

When I was growing up, food was always a complicated issue for me. I hated vegetables, loved sugary foods, and drank soda whenever I could get my hands on it. After a chubby childhood, I went off to university and gained almost 10 kilos as a result of no exercise, too much beer and crappy cafeteria food. I didn’t feel good in my own skin (or my clothing!) and I didn’t like what I saw in the mirror… so I knew something had to change.

The problem was I didn’t really know where to start! I knew less beer and more vegetables was probably a good idea, so I started with that! For exercise, I started trying to go to the gym once or twice each week, and began attending a bootcamp class with some friends. With a bit of work on the QUALITY of my nutrition plus more overall movement in my daily life, I noticed my clothing fit better and I was liking what I saw in the mirror.

That was a good start, but in order to reach my goals, I needed to take my nutrition a step further. Finding the balance between eating the right types of foods and eating the right AMOUNT can be tough! After moving to Barcelona, I started Olympic Weightlifting, and in order to fit into my weight class category, I found I needed to drop a few more kilos. A friend of mine who had competed on an international level in body building suggested “macro-counting” (a form of flexible dieting)- basically, weighing and measuring my food intake. By adding precision to my diet, I was not only able to lose body fat, but able to maintain (and even improve!) my strength in my sport.

Since then, I have found a point in which I am able to maintain a body composition and performance level that works well for my lifestyle without weighing and measuring what I eat every day… because no one wants to eat out of tupperware for the rest of their lives.

It has been a long road to becoming a Nutritional Coach! Over the last 10 years, I have studied and experimented with tons of different diet theories- everything from vegetarian to Paleo to “gluten-free”. I completed the Holistic Health Coach certification with the Institute of Integrative Nutrition in 2011 and also hold the Level 1 coaching certification from Precision Nutrition (both EEUU certifications). In 2017 I completed ANEF’s Sports Nutrition course in Barcelona, and have been working as a CrossFit and Bootcamp coach for the last 3 years. I also hold the CrossFit Level 3 certification (CCFT) and am proud to be one of less than 15 people in all of Spain to hold this title.

I love working with clients to help them find what works best for their nutrition and lifestyle, and outside of my work I spend countless hours reading studies, books and articles in order to always stay on top of the newest information in the world of nutrition!
