Behaviour-Change Method

To see results, you’ll need to be consistent. To be consistent, you’ll need help.

Lose weight, build strength, and have more energy.

I always start with your needs and goals. Then we’ll work together to develop a plan to help you eat, move, and live better—in a way that works for your body, and your life.

Get the support you need—every step of the way.

I’ll remove all the guesswork and provide the accountability, direction, and support you need to stay consistent, no matter what life throws at you. We’re in this together.

Achieve your goals—even when life gets crazy.

I’ll break your big goals into small daily practices that add up to massive changes. As a result, you’ll progress toward your goals without ever feeling overwhelmed, and build habits that last a lifetime.

Health benefits beyond weight loss.

My science-based coaching method does more than just teach you how to eat better. In the end, it won’t be just about what you lose, but what you’ll gain: knowledge, control, and the confidence that comes with knowing you’re capable of anything.

No more weird diets or unrealistic workouts.

You don’t have to go to extremes to get amazing results. I’ll help you achieve your goals without flipping your life upside down.

One-on-one coaching done right.

Build the habits you need to look and feel better for life. (Here’s how it works.)


Easy-to-use online platform

You’ll start by telling me all about yourself, including your goals, health challenges, and daily routine. From there, I’ll customize your entire program and we’ll start the proven coaching process.


Small yet powerful practices to improve everyday life

We’ll work together to create and practice healthy habits across every aspect of your life, from sleep and stress-management to movement and mindfulness. These new habits will help you feel more calm, confident, and prepared for each day—no matter what life throws at you.


Simple practices and daily accountability

Every day, you’ll work on nutrition or lifestyle practice. Each practice will be customized to help you get the results you are looking for.


Personal coaching and detailed progress checking

I’ll check in with you frequently to see how you’re doing and to answer any questions you have. Also, you can message me whenever you need. The program also tracks everything from your measurements to your consistency, so you can see just how much progress you’ve made.

Limited spots available

How to get into the best shape of your life — and stay that way.

Expert nutrition coaching and personal accountability from Coach Nicolas Gunn.

Transform your body forever

You tell me what you want to do. I’ll help you do it. First, I’ll learn about your lifestyle, needs, and specific goals. Then, over the course of the program, I’ll give you everything you need to look, feel, and perform better than you thought possible.

Proven strategies to help you get (and keep) the body you want

You’ve probably tried multiple diet and workout programs in the past. And you’ve concluded that they simply don’t work in the long run.

Instead of the all-or-nothing dieting approach, I use a sustainable, practice-based approach to build healthy habits into your life, one day at a time.

The result? You’ll lose the weight (and inches) you haven’t been able to shed for years. You’ll have more energy than ever before. And you’ll build physical strength and find new confidence in your body.

Stay accountable and consistent with personal help from me

I live and breathe this stuff every day, and have dedicated my professional life helping people like you become fitter, stronger, and healthier than ever.

Whatever obstacles arise, I’ll help you overcome them by modifying your program or offering new solutions. In the end, know that I’m here to support you every step of the way, no matter what life throws at you.
