Insulin Resistance Adelaide

Tired, craving sugar, gaining weight, but blood tests look “normal”?

 

Sometimes the body starts to feel different even when standard blood tests appear normal.

Energy may disappear halfway through the afternoon. Hunger can return soon after eating. Sugar or carbohydrate cravings may become stronger. Weight can become harder to shift, particularly around the middle.

Concentration may not feel as sharp. Sleep may no longer feel restorative. Coffee, snacks or sheer willpower can start filling the gaps.

Perhaps you have already had blood tests and been told:

“Everything looks fine.”

But things still do not feel quite right.

There can be many reasons for changes like these.

One area worth understanding is metabolic health, including how well the body is responding to insulin.

There is no need to already understand insulin resistance before seeking support.

The starting point is simply the pattern.

This page is for general education only. It does not diagnose insulin resistance, prediabetes, diabetes or any other medical condition.

What is insulin?

Insulin is a hormone produced by the pancreas.

One of its main roles is to help move glucose from the bloodstream into cells, where it can be used or stored for energy.

When cells become less responsive to insulin, the body may need to produce more insulin to achieve the same effect.

This reduced response is known as insulin resistance.

It often develops gradually.

For some people, blood glucose can remain within the normal range for some time because the body is compensating by producing more insulin.

That is why metabolic health is not always reflected by a single blood glucose result.

Does any of this sound familiar?

None of these signs proves insulin resistance, and many have other possible causes.

When several appear together, the overall pattern may be worth exploring.

Common changes can include:

• afternoon energy slumps

• frequent cravings for sweet or carbohydrate rich foods

• hunger returning soon after meals

• increasing weight around the abdomen

• difficulty losing weight despite effort

• poor concentration or mental fatigue

• sleep that does not feel restorative

• relying on caffeine to keep going

• skin tags

• loud snoring

The broader picture matters more than any one symptom.

Sometimes there are no obvious symptoms

Insulin resistance and prediabetes do not always produce noticeable symptoms.

Personal and family risk factors can therefore be just as important as how someone feels.

A conversation with a GP may be worthwhile when one or more of the following are present:

• family history of type 2 diabetes

• PCOS

• previous gestational diabetes

• high blood pressure

• elevated triglycerides

• low HDL cholesterol

• fatty liver disease

• sleep apnoea

• increasing abdominal weight

• previously elevated blood glucose

• a history of prediabetes

Age, genetics, medications, activity levels, sleep, nutrition and other health conditions can also influence metabolic health.

But my blood sugar was normal

Insulin resistance and diabetes are related, but they are not the same thing.

In the earlier stages, the body may compensate for reduced insulin sensitivity by producing more insulin.

Blood glucose can therefore remain within the laboratory reference range for a period of time.

Normal glucose does not prove hidden insulin resistance, but it also does not describe the entire metabolic picture on its own.

What may be worth discussing with a GP?

A GP is the appropriate person to diagnose prediabetes, diabetes and other medical conditions.

Depending on medical history, symptoms and risk factors, investigations may include:

Test or measure	Why it may be considered
Fasting glucose	Measures blood glucose after a period without food
HbA1c	Gives an indication of average blood glucose over approximately 2 to 3 months
Oral glucose tolerance test	May be used in certain circumstances to assess how the body handles glucose
Triglycerides and HDL cholesterol	Form part of the wider cardiometabolic picture
Blood pressure	An important cardiovascular and metabolic health measure
Waist circumference	Can provide additional information about cardiometabolic risk
Liver enzymes	May be considered when assessing possible metabolic liver changes
Other investigations	Additional testing may be recommended depending on symptoms, medications and medical history

Some practitioners also consider fasting insulin in selected situations.

Fasting insulin is not routinely used as a standard diagnostic test for insulin resistance, and there is no single universally accepted fasting insulin cut off that diagnoses the condition.

A GP can determine whether additional testing may provide useful information.

The numbers are only part of the picture

Blood tests matter, but everyday patterns matter too.

These can include:

• eating habits and meal timing

• appetite and cravings

• energy after meals

• sleep quality

• movement and activity

• stress load and recovery

• hormonal changes

• medications

• medical and family history

These areas are often considered separately.

Looking at them together can sometimes make the overall picture clearer.

Metabolic Health Assessment

No diagnosis is needed

There is no need to already understand insulin resistance before coming in.

The starting point can be as simple as:

“Something has changed, and I want to understand what might be contributing.”

A Metabolic Health Assessment provides time to step back and look at the broader pattern rather than focusing on one symptom at a time.

Areas explored may include:

• energy and appetite patterns

• eating habits

• sleep quality

• stress and nervous system load

• movement and activity

• changes in weight or body composition

• relevant health history

• previous pathology results

• questions that may be useful to raise with a GP

The purpose is not to diagnose a medical condition.

The aim is to identify patterns, provide general lifestyle guidance around food, sleep, movement and stress, and recognise when medical follow up may be appropriate.

Supporting metabolic health

There is no single diet, supplement or exercise program that is right for everyone.

Depending on individual circumstances, metabolic health may benefit from attention to:

• minimally processed foods

• adequate protein

• dietary fibre

• carbohydrate quality and quantity

• regular movement

• resistance exercise

• reducing long periods of sitting

• restorative sleep

• appropriate treatment of sleep apnoea

• stress management

• reducing excess alcohol

• maintaining an appropriate weight where clinically relevant

The most useful approach is generally one that can be maintained consistently rather than an extreme short term program.

Nutritional foundations, trace minerals and hydration

Metabolic health involves more than glucose and insulin.

Adequate nutrition, hydration and essential minerals support normal muscle function, nerve signalling, fluid balance and energy metabolism.

Minerals such as magnesium, potassium and sodium all have important roles in normal body function.

More is not necessarily better.

Supplement needs vary between people, particularly when medications are being used or when kidney, heart or blood pressure conditions are present.

Potassium in particular may not be appropriate to supplement without professional guidance in some circumstances.

A separate resource explains trace minerals, electrolytes and hydration in more detail.

What about metabolic support products?

Nutrition, movement, sleep and other lifestyle foundations remain important.

Some clients also ask about the Unicity Feel Great System.

Use of Unicity products is completely optional and is not required to work with me.

The Unicity Feel Great System

Feel Great combines Unicity products with a time restricted eating approach.

Unimate

Unimate is made with concentrated yerba mate extract.

Unicity’s current Australian product material describes Unimate as supporting cognitive function and focus.

It contains naturally occurring compounds found in yerba mate, including theobromine and caffeine.

Balance

Balance is a fibre based nutritional supplement used before meals as part of the Feel Great program.

For current Australian product information, ingredients and permitted claims, refer directly to Unicity’s Australian information.

What does the research say?

Unicity maintains a research site containing studies relating to Balance, Unimate and the Feel Great program.

Research listed there includes studies examining post meal glucose responses, appetite, HbA1c, body weight, waist circumference and other metabolic measures.

As with any research, study design matters.

One 60 day Feel Great study involved 42 healthy adults aged 20 to 65.

Participants followed a program combining Unimate, Balance and a 14 to 16 hour overnight fast.

Because several elements were used together, the study does not establish how much of any observed change was attributable to Unimate, Balance, fasting or the combination.

Because the participants were healthy adults, the findings may not apply in the same way to people with diagnosed insulin resistance, prediabetes or diabetes.

Frequently asked questions

Can insulin resistance occur when blood sugar is normal?

It can.

During earlier stages of insulin resistance, the pancreas may compensate by producing more insulin, helping keep glucose within the normal range.

Normal glucose does not by itself prove or exclude insulin resistance.

Medical history, risk factors and appropriate clinical assessment matter.

Can insulin resistance cause fatigue?

Fatigue can occur alongside impaired glucose regulation and metabolic dysfunction, but it has many possible causes.

These include poor sleep, anaemia, thyroid conditions, nutrient deficiencies, medications, hormonal changes, infection, mood disorders and chronic health conditions.

Persistent or unexplained fatigue should be discussed with a GP.

Can insulin resistance cause brain fog?

Difficulty concentrating or mental fatigue can occur alongside many health conditions.

Brain fog is not specific to insulin resistance.

Sleep, stress, menopause, medications, thyroid dysfunction, iron or B12 deficiency and other factors may contribute.

That is why looking at the whole picture matters.

Can insulin resistance affect sleep?

Sleep and metabolic health are closely connected.

Poor sleep can influence glucose regulation and insulin sensitivity.

Conditions such as obstructive sleep apnoea are also associated with metabolic disease.

Persistent snoring, breathing pauses during sleep, significant daytime sleepiness or suspected sleep apnoea deserve medical assessment.

Can insulin sensitivity improve?

Yes.

Physical activity, nutrition, sleep, weight management where appropriate and other lifestyle factors can improve insulin sensitivity and metabolic health.

How much improvement occurs varies between individuals and depends on many factors.

Is weight loss always necessary?

No.

Movement, resistance training, sleep and improved food quality can benefit metabolic health even without substantial weight loss.

For some people with overweight or obesity, reducing body weight can significantly improve insulin sensitivity and cardiometabolic risk.

The appropriate goal varies from person to person.

Do carbohydrates need to be eliminated?

No.

Carbohydrates are not all the same.

The amount, type and overall dietary context matter.

Vegetables, legumes, whole grains and fruit are very different nutritionally from sugary drinks, confectionery and highly refined foods.

The aim is generally to improve overall food quality rather than fear an entire food group.

Should fasting insulin be tested?

It can be discussed with a GP.

Some clinicians use fasting insulin in selected circumstances, but it is not universally recommended as a routine diagnostic test for insulin resistance.

A GP can determine which investigations are appropriate based on medical history and individual risk factors.

Do you diagnose insulin resistance?

No.

Diagnosis and medical investigation belong with a GP or another appropriately qualified healthcare professional.

My role is complementary.

I provide general lifestyle education, help identify patterns and support conversations with healthcare providers.

When should medical advice be sought?

Persistent, unexplained or concerning symptoms deserve medical assessment.

Prompt medical care is particularly important for symptoms such as:

• chest pain

• significant shortness of breath

• fainting

• a new or persistent racing or irregular heartbeat

• unexplained swelling

• excessive thirst and urination

• unexplained significant weight loss

• severe or rapidly worsening fatigue

• any sudden, severe or unusual symptom

Information on this page should never be used to delay medical assessment.

Sometimes the first step is simply making sense of the pattern

Energy changes.

Appetite changes.

Sleep changes.

Weight or body composition changes.

None of these automatically means insulin resistance is the cause.

But when several changes begin happening together, the overall pattern may be worth understanding.

A Metabolic Health Assessment provides time to look at those pieces together, identify practical lifestyle priorities and recognise what may need further discussion with a GP.
