Metabolism Testing For Fat Loss

What we test with metabolic testing

VO2Max and lactate testing - How fit are you?

Fuel utilisation/metabolic efficiency - How effective are you at burning fat?


Energy expenditure - how many kcals do you burn at different intensities/zones


Resting Metabolic Rate (metabolism) Test - How many kcals do you burn at rest

Performance testing also includes  speed and power at your aerobic and anaerobic thresholds as well establishing your training zones.

Improve Metabolism

​Metabolism is the process by which your body converts food into energy. A fast metabolism means that your body is able to effectively use the calories you consume, while a slow metabolism can lead to weight gain. There are a number of factors that can affect your metabolism, including your age, genetics, and activity level.

However, there are also some lifestyle changes you can make to improve metabolism. Eating more food is one of the easy fixes to help increase the amount of calories you burn at rest. More Regular exercise can also help improve metabolism, by improving your ability to use and store carbohydrates.

Building more muscle tissue can also help speed up your metabolic rate, as muscle is more metabolically active than fat tissue. Sleep deprivation can lead to weight gain as it alters hormone levels which impact metabolism and hunger cues. likewise, high stress can impact food choices. So try and get a good nights sleep and take it easy! Making these simple changes can help to give your metabolism a boost.

Broken Metabolism Symptoms

​Although it is unlikely that your metabolism is broken, a metabolism that isn't working as quickly as normal is a problem amongst some. Low-energy levels, frequent fatigue and trouble losing weight are all signs that your metabolism could use a boost. If you're struggling to lose weight, even though you're eating healthy and exercising regularly, it could be a sign that your metabolism is slow (not broken).


Symptoms of a suppressed metabolism include:

  • Fatigue

  • Headaches

  • Weight gain

  • Constipation

  • Depression

  • Hair loss

  • Dry skin

  • Muscle weakness

  • Brain fog

  • Cold intolerance

  • Decreased libido

Another way to boost there are a number of things you can do to improve your metabolism, including eating more protein, getting more sleep, and exercising regularly. If you're struggling with any of these symptoms, it's important to talk to your doctor to see if there might be an underlying medical condition causing them. Treating the underlying condition can often help to improve the symptoms.

Testing Data

After a metabolic testing session, you will receive a complete breakdown and debrief session running through the testing data.


This includes:

  • Training zones and thresholds


  • Kcal expenditure and speed/watts at each zone


  • Metabolic efficiency point - carb vs fat burn


  • Identification of strengths and weaknesses against normative values


  • RMR report - resting metabolic rate and predicted daily kcal requirements
