Transform Your Body, Improve Metabolism and Lose Weight For Good

  • Are You Stuck In A Cycle of Low Calorie Dieting And Not Seeing Results?

  • Are You Tired Of Not Being Able to Eat 'Normally' Without Gaining Weight?
  • Box Nutrition Has The Solution - Metabolism Testing & Nutrition Coaching

Millions of people diet each year, but almost all of them will regain the weight they lose. 

Dieting is hard. It's tempting to cut out entire food groups or have another go at that diet which didn't work last time.


But this kind of restrictive dieting is not sustainable in the long term, and it often leads to feelings of guilt and frustration when you can't stick to your plan.

Ignite is a different kind of diet programme. We use metabolism testing to help understand your unique needs and nutrition coaching to help you create a healthy, sustainable diet that fits into your lifestyle.


Our programme is designed to help you break free from chronic dieting and finally achieve your fat loss goals.

Ignite uses a combination of clinical tests and advanced technology to build a nutrition and exercise plan that is tailored specifically for your unique metabolism.


That means you’ll see results faster, and you’ll be able to keep the weight off for good.

Tone up, slim down, and feel better than ever before with Ignite by Box Nutrition. Our Nutrition Coaching, Metabolic Testing / Metabolism Testing Transformation Programme will help you lose 5-10lbs per month, without any restrictive diets or gruelling workouts.

It's Not Your Fault

Do you find that you’ve tried everything but nothing seems to work?

You’re not the only one.

With SO much information currently available, it can be difficult to know who to believe, what to do and where to start.


Even ‘experts’ can’t agree:

“Just eat less”… “You need to eat more to fire up your metabolism”

“Cut out carbs”…. “You need to eat carbs to exercise”

“Create a kcal deficit”…. “Kcals don’t matter!”


It’s confusing right??!!?

This is the reason why it's not your fault.

You need a plan that is specific to your needs and to your body.

This is how we can help.

Through a simple process called metabolic testing, we can measure exactly how many calories you need to help you lose weight, without having to starve yourself. Have you ever wondered if your metabolism is slow? We can find out.

We also use something called VO2 testing to measure your calorie and fat burning during exercise so you know what to do to lose fat most efficiently.

This is Ignite, the fat loss programme specifically for people struggling to break the diet cycle.

How Does It Work?

IGNITE uses a three step system.

Step 1 - Metabolic / Metabolism Testing 

Test Don't Guess!


We use something called metabolic testing to help people like you finally break the diet cycle and eat normally without gaining weight.


Our metabolic testing service uses a combination of clinical tests and advanced technology to build nutrition and exercise plans that are tailored specifically for your unique metabolism. Unlike other coaches who simply guess your calories and macros and hope for the best or, macro calculators which are woefully inaccurate.

1. Test Your Metabolism

From a simple RMR (resting metabolic rate test) we can measure exactly how many kcals you burn at rest. From this we can provide you with the number of kcals (how much food) you need to help you lose weight, but most importantly how much you can eat without starving yourself! Who wouldn’t want to eat more food if they didn’t have to.

The metabolism testing is a simple test, which involves you sitting down and relaxing for 20mins. You breath into a mouth piece and using a metabolic cart, we measure the oxygen that you’re breathing in and the carbon dioxide that you’re breathing out. This ratio helps us determine how many kcals you burn at rest. This is called indirect calorimetry. This is the gold standard for measuring calorie burn.

2. Test Your Body Composition

Using the premier body composition analyser, the InBody 270, we measure how much lean mass you have in each body segment, as well as segmental fat and visceral fat analysis. In conjunction with your metabolic data, this body composition analysis helps us to provide a unique nutritional plan and exercise regimen for you to optimise fat loss and muscle gain.

3. Test Your Active Calorie and Fat Burn

Don't be scared by this part! This simple test helps us measure how many kcals you burn (accurately) and your fat burning capability, which shows us the most efficient way for you to lose fat and get fit. We can also use this test to help design an exercise plan based on your specific heart rate data and current fitness level.

What is the Fitness Test?

The Fat Max or VO2 test is a simple exercise test performed on a treadmill or bike, where the speed or resistance increases gradually until you can’t exercise any longer.


The speed is based on your fitness level and can be done either walking or running. You do NOT need to be fit to do this test.

During the test, you will be wearing a mask connected to the metabolic cart. The metabolic cart will analyse the oxygen you breathe in and the carbon dioxide you are breathing out. You will also be wearing a heart rate monitor to gather as much information as possible about your health and fitness. 

From the data, we can accurately assess your calorie and fat burn during activity, as well as being able provide you with exercise sessions to help supercharge both your fitness and fat loss.

Step 2 - Metabolic Cycling

Fortunately you can't break your metabolism, but past and present diet, exercise, lifestyle choices and behaviours will bend and mould it to either help, or hinder your progress.

This is where pillar 2 comes in - Metabolic Cycling. This 3 phased approach helps you avoid the 'race to the bottom' diet culture and instead, focuses on building you up and priming your body to burn fat instead of storing it.

Phase 1 - The Reset

Phase 1 is the reset phase, which helps restore your metabolic rate to normal. During this time we help rediscover your energy levels, improve your training and support your health.

Exercise will be heavily based around getting you stronger and managing your NEAT/cardio correctly. This will be tailored to your current situation and exercise history.

If your metabolic rate is normal, you will skip this phase and go straight to phase 2.


Phase 2 - The Cut

After a second RMR test, a new 12-16 week fat loss phase will help implement a sustainable deficit that helps improve the way you look and doesn't compromise your metabolism. This helps you eat the most amount possible so you can still lose weight and not feel deprived.

This is when the intensity will ramp up and you will begin to see the fruits of your labour.

Phase 3 - Maintain

At this stage of the programme, the goal is to move away from tracking and be more intuitive with your eating. You should also now have found an exercise regime that has become part of your daily routine.


If you haven't reached your target weight, you will enter a second cutting cycle only after you have finished a 4-8 week maintenance phase. This helps restore hunger hormones back to normal, gives you a psychological break from dieting as well helping with energy levels and improvements in fitness.

Step 3 - Nutrition and Exercise Coaching

The key part of Ignite's success is access to your own nutrition and exercise coach. We understand that the data isn't enough, which is why your coach will act as your accountability to keep you on track and ensure you keep moving towards your goals

Understanding metabolism and how it affects your weight loss goals goes beyond just creating a calorie deficit and setting some macros. This is where coaching comes in. Your nutrition and exercise coach will not only help you understand how your metabolism works, but they will also be able to provide nutritional guidance and create a nutrition plan that is tailored specifically for you – taking into account your unique metabolism and factors that could be affecting it.


The nutrition element of the programme combines focusing on key drivers such as calories and macros, but also habits that form the foundations for long term success. These include hitting fibre, water and micronutrient targets, understanding about portions, balancing meals, learning how to control cravings or how to prep properly for the week.

Your coach is there to help you to find a setup that suits your lifestyle, to make it as easy as possible to stick to your plan.


The activity part of Ignite factors in your testing results and exercise history, so we put together an activity plan that is based on your individual needs. More is NOT always better. Depending on your results and preference, this may favour my weights, more cardio or even just walking.


Ignite is all about results. This is why as part of the programme you have a number touch points with your coach to ensure you stay on track. These include weekly diary checks, bi-weekly check in calls and a in person check in 2 3 months into the programme.
