From veggie hater to food obsessed finally becoming a balanced, confident eater.

Hi, I’m Gillian

I’m currently the healthiest and happiest I’ve ever been, and (most days) feel incredibly comfortable in my body… but it’s been a long road to get here. Food and my body were constant sources of self doubt, stress and frustration for most of my life.

When I was younger, there were so many rules in my home about which foods were ‘good’ and which were ‘bad’, and while I knew that eating vegetables and less processed food was ‘healthier’, I rebelled. 

When I got to college, all I wanted was pizza, breakfast cereal and Starbucks coffee cake- all the stuff my dad wouldn’t let us eat.

Eventually, like many of us when we head to college, my jeans didn’t fit. This was the spark that got me interested in nutrition.

When I finally decided to change my eating habits on my OWN terms, it was a learning process.

Slowly, I practiced including more vegetables and less processed food into my diet and I started exploring new types of exercise. I stopped smoking, and reduced my alcohol intake. Little by little, I saw the results of these small changes add up- I had way more energy, and for the first time in my life, I lost weight without even really ‘trying.’


When I discovered dieting, it exposed a lot about my issues with food + body

When I moved to Barcelona in 2014, I really got into CrossFit (I even ended up coaching CF for over 5 years!) 

When I found CrossFit, my desire to just be skinny transformed into a deep desire to look like a ‘fit girl’. I believed that if I could just have the ‘perfect’ body… life would be easier.

It was the first time I actually went on a specific diet for fat loss, and I went from loving eating out with friends and travelling to stressing over hitting my macros, constantly checking myself in the mirror, and obsessively weighing myself and pinching my belly in the mirror. 

I thought my insecurities about my body would disappear when I was lean, the reality was that I was more preoccupied with my weight and my body than ever.

I was SO strict with my nutrition and training that my physical and mental health suffered. I would wake up hungry in the middle of the night, was losing my hair, had ZERO sex drive, and felt lonelier than ever.

HERE’S THE THING: I knew exactly ‘what to do’ to eat healthfully- I was already coaching nutrition! But instead of following the balanced eating recommendations I gave my clients, my desire to keep my body looking a certain way took precedence.

Luckily, my love for reading nutrition and psychology books + research uncovered the concepts of Mindful and Intuitive Eating. As I learned, I finally understood how restriction had affected my ability to have a balanced relationship with food.

I learned to manage my thoughts, emotions and cravings and how to finally nourish my body with care and respect.

It took practice to re-establish my hunger and fullness cues after years of dieting, and mindful eating helped me become an expert in my own body.

Now, my relationship with food AND my physical health are better than ever…


A great relationship with food is possible for you, too. Bite Size Nutrition programs include nutrition, psychology and mindfulness to help you build trust in your body and your decisions around food.


Every single aspect of my day to day life has improved since working with Gillian, and I say that without exaggeration.

My mindset towards health has completely shifted.

I missed out on so many life events I wanted to participate in because I was scared to not have total control over my food. Gillian helped me to challenge the beliefs I had, and was patient when I was fearful to try new habits. In the end, I feel much more confident being an active participant in my life. 

Before working with Gillian, I would say no to things in life that I really wanted to do because I was afraid of not being able to count my macros and I would overeat anytime I wasn’t controlling what I ate.

If I knew a friend who was struggling I would want them to get the same support and help I got from working with Gillian.

Why I became a coach + my education

I became a coach because I know how hard it is to find balance… and the ‘health and wellness’  industry makes it seem like health has to be all or nothing.

My goal for ALL my clients is to feel like they have autonomy over their bodies, and can trust themselves to choose to eat in a way that supports their physical and mental health.

My journey to become a coach started in 2011, with a certification from the Institute of Integrative Nutrition. Over the last decade, I’ve continued to educate myself with completed multiple nutrition and psychology courses, including Acceptance and Commitment Therapy, Body Image, and Motivational Interviewing. (scroll down for a full list of my professional education)

My coaching style combines nutrition science, psychology, behavior change and mindfulness practices… because just ‘knowing what to eat’ is NOT enough.

What's Bite Size Nutrition all about?

My coaching framework teaches you how to eat in a way that aligns with the type of life you want to live- because our diet should fit into our ideal life, not the other way around.

My coaching includes principles of motivational interviewing, intuitive and mindful eating, behavior change psychology and a holistic approach to health to changing your habits for good.

Working with me, you’ll learn why you do what you do, and how to change it to support a great relationship with food. It’s not just nutrition coaching, it’s behavior and mindset change.

I started Bite Size Nutrition in 2016 to help women feel in charge of their eating habits and at home in their bodies… because I know the stress, overwhelm and frustration that comes with dieting and body shame.

Bite Size Nutrition Coaching will help you break your all or nothing patterns and learn how to create (and maintain!) balance in your eating habits.
