AM I INSULIN RESISTANT? — THE 6-PART SERIES
Part 4: Sugar & Carb Cravings — Could Frequent Cravings Be a Clue to Insulin Resistance?
Published: September 2026 | Reading Time: 9–11 minutes
You have eaten lunch.
A couple of hours later, you want something sweet.
Not because dessert simply sounds nice.
It feels more urgent.
A biscuit. Chocolate. Bread. Something starchy. Something that gives you energy quickly.
Perhaps the craving arrives with hunger, irritability, tiredness or that familiar afternoon dip.
Does craving sugar mean you are insulin resistant?
No.
Food cravings are common and can be influenced by many things—from sleep and stress to menstrual-cycle changes, habits, food availability and simply enjoying sweet foods.
But frequent, intense cravings for sugar or refined carbohydrates—particularly when they occur alongside increased hunger, energy dips or other metabolic clues—may sometimes be worth looking at in a wider metabolic context.
Cleveland Clinic notes that increased hunger can occur when insulin resistance has progressed to the point that blood glucose is persistently elevated.
Earlier insulin resistance may cause no obvious symptoms at all.
Metabolic-health education sources, including SustainMD and Rejuvime/WAFB sponsored content, also describe strong sugar and carbohydrate cravings among patterns reported by some people with insulin resistance.
But these cravings are not established diagnostic criteria.
The important word is pattern.
In Part 4 of Diafemme's “Am I Insulin Resistant?” series, we separate an ordinary desire for something sweet from cravings that may be occurring alongside unstable energy, hunger and metabolic risk.
Quick Highlights
- Craving sweets or carbohydrates occasionally is normal and does not mean you have insulin resistance.
- Early insulin resistance may cause no obvious symptoms while the pancreas is still compensating adequately.
- As insulin resistance progresses and blood glucose remains elevated, increased hunger can occur.
- Some metabolic-health education sources describe sugar and refined-carbohydrate cravings among patterns reported by people with insulin resistance.
- The scientific evidence linking specific sugar cravings directly to insulin resistance is less established than the evidence for signs such as acanthosis nigricans or central adiposity.
- A craving becomes more interesting metabolically when it repeatedly occurs with hunger, fatigue, post-meal energy dips, shakiness or other metabolic risk factors.
- Stress, sleep loss, restrictive dieting, menstrual-cycle changes and learned eating habits can also influence cravings.
- Cravings alone cannot diagnose insulin resistance, prediabetes or diabetes.
Diafemme Knowledge Card
What Are We Looking At?
Frequent or unusually intense cravings for sweets or refined carbohydrate foods.
Examples
Chocolate, sweets, biscuits, sugary drinks, white bread, bakery foods, chips or other rapidly digested carbohydrate-rich foods.
Why Might They Matter?
Some people experiencing disturbed glucose and insulin regulation also report increased hunger, carbohydrate cravings and energy dips.
Does Wanting Something Sweet Mean Insulin Resistance?
No. Cravings are highly nonspecific.
When Are They More Worth Noticing?
When they are frequent, intense, recurring after meals or accompanied by hunger, fatigue, shakiness or other metabolic clues.
Most Important Principle
Look for a recurring pattern—not an isolated craving.
First, What Do We Mean by a “Craving”?
Hunger and craving are not exactly the same thing.
Hunger is the body's broader drive to obtain food.
A craving is usually a stronger desire for a particular food, taste or type of food.
You may be physically hungry and crave food.
But you can also crave chocolate while not particularly wanting a full meal.
That distinction matters because cravings are influenced by far more than glucose alone.
They may reflect:
- habit
- reward and pleasure
- stress
- sleep deprivation
- food restriction
- environmental cues
- menstrual-cycle changes
- emotional state
- meal composition
So the question is not:
“Do I ever crave sugar?”
Most people do.
A more useful question is:
“Is there a recurring pattern to when, how strongly and under what circumstances these cravings occur?”
What Might Insulin Resistance Have to Do With Hunger?
Insulin helps regulate blood glucose and supports the movement and storage of glucose in tissues.
With insulin resistance, cells in muscle, fat and liver do not respond to insulin as effectively as they should.
The pancreas may initially compensate by releasing more insulin.
During this earlier stage, blood glucose may remain within the normal range.
That is why insulin resistance may exist without obvious symptoms.
If insulin resistance progresses and the pancreas can no longer compensate sufficiently, blood glucose may remain persistently elevated.
At that stage, symptoms associated with high blood glucose may appear.
Cleveland Clinic lists increased hunger among these symptoms.
This gives us a clinically supported connection between worsening glucose regulation and appetite.
But increased hunger is still not the same as specifically craving sugar.
The clearest clinical evidence supports increased hunger when glucose regulation has worsened. Specific cravings for sweets or refined carbohydrates are less specific and should not be treated as a diagnostic symptom of insulin resistance.
Why Might Someone Reach for Sugar or Refined Carbohydrates?
Sugary and highly refined carbohydrate foods are rapidly digested and can raise blood glucose relatively quickly.
They are also highly palatable and strongly associated with reward.
Metabolic-health education sources such as SustainMD and Rejuvime/WAFB describe a pattern in which some people with insulin resistance report stronger desires for carbohydrate-rich foods, particularly when they also experience hunger or low-energy sensations.
One proposed explanation is that changes in appetite and energy-regulation signals may influence the desire for quick-energy foods such as sweets, bread, pasta or chips.
This is plausible, but it is not a proven universal mechanism.
Human appetite is regulated by a complex interaction involving:
- blood glucose
- insulin
- gut hormones
- brain reward pathways
- sleep
- stress
- learned behaviour
- food environment
So it is safer to say:
Frequent sugar or carb cravings may sometimes occur alongside impaired glucose and insulin regulation—but cravings do not uniquely identify insulin resistance.
Does the Craving Become More Meaningful When an Energy Dip Comes With It?
Potentially.
This is where looking at combinations becomes more useful than looking at a craving alone.
Imagine a recurring pattern:
You eat a carbohydrate-heavy meal.
A few hours later, you feel tired.
You become hungry again.
You feel irritable or unable to concentrate.
And suddenly you strongly want something sweet or starchy.
Metabolic-health education sources describe combinations such as:
- strong carbohydrate or sweet cravings
- afternoon fatigue
- increased hunger
- brain fog
- feeling shaky or irritable between meals
That pattern can provide a reason to look more closely at metabolic health.
But it still cannot tell us what is causing the symptoms.
Sleep deprivation, long gaps between meals, restrictive dieting, stress and other factors can produce similar experiences.
The craving itself is weak evidence. The repeating sequence—meal → energy dip → hunger → craving—may be more informative.
Does Frequent Sugar Craving Mean “I Am Insulin Resistant”?
No.
This distinction is especially important in Part 4 of the series.
Compared with acanthosis nigricans, which has a much more established association with insulin resistance, a food craving is far less specific.
You may crave sugar because you:
- have not eaten enough
- have gone too long between meals
- slept poorly
- are stressed
- have deliberately restricted carbohydrates
- have developed a habitual snack pattern
- are experiencing menstrual-cycle-related appetite changes
- simply enjoy sweet foods
None of these possibilities automatically excludes metabolic dysfunction either.
It simply means cravings need context.
Specific sugar and carbohydrate cravings are described mainly by metabolic-health education platforms rather than major diagnostic guidelines. Major clinical sources more clearly support increased hunger as glucose regulation worsens. Cravings should therefore be considered a possible associated pattern, not an established clinical sign.
Can the Foods We Crave Also Affect Glucose and Insulin?
Yes.
This relationship can move in both directions.
Cleveland Clinic notes that high-glycemic foods generally contain larger amounts of rapidly digested carbohydrates or sugar.
They can raise blood glucose quickly and require a stronger insulin response.
Examples may include:
- sugary drinks
- white bread
- many breakfast cereals
- cakes and cookies
- other refined starches and sweets
This does not mean carbohydrate foods are inherently harmful.
Nor does insulin resistance require eliminating carbohydrates.
But when an eating pattern repeatedly relies on rapidly absorbed refined carbohydrates, glucose and insulin responses may be less stable than with meals containing more fibre, protein and minimally processed foods.
So the practical objective is not:
“Never eat sugar again.”
It is:
“Can I create meals that leave me more satisfied and produce a steadier metabolic response?”
Why Can Cravings Be Particularly Complicated for Women?
Because appetite does not operate separately from hormonal life.
Women may experience changes in appetite or food preference across:
- the menstrual cycle
- pregnancy
- the postpartum period
- perimenopause
- menopause
- PCOS
Stress, sleep disruption and changing routines can add further influences.
This means that a woman noticing stronger cravings should not immediately assume insulin resistance.
Instead, ask whether the cravings:
- occur at a predictable point in the menstrual cycle
- appear after particular meals
- follow poor sleep
- occur on stressful days
- arrive with fatigue or shakiness
- are new or markedly stronger than before
Women with PCOS may also have insulin resistance, so cravings occurring alongside irregular cycles, central fat, acanthosis nigricans or abnormal glucose deserve a broader perspective.
What Else Should You Look at Before Blaming Insulin Resistance?
Think of cravings as one possible piece of information.
The picture becomes more meaningful if other metabolic clues are present.
- increasing waist circumference
- acanthosis nigricans
- multiple skin tags
- recurrent post-meal energy dips
- persistent increased hunger
- higher fasting glucose
- higher HbA1c
- high triglycerides
- low HDL cholesterol
- high blood pressure
- PCOS
- history of gestational diabetes
- family history of type 2 diabetes
Several independent clues occurring together are much more informative than craving one particular food.
Could You Track the Pattern for a Week?
You do not need to count every gram of carbohydrate or turn eating into a laboratory experiment.
For a week or two, simply notice:
| Notice | Ask Yourself |
|---|---|
| Time | When does the craving usually arrive? |
| Previous Meal | What and when did I last eat? |
| Hunger | Am I genuinely hungry or specifically wanting one food? |
| Energy | Do I also feel tired, shaky or unfocused? |
| Sleep | Did I sleep poorly the night before? |
| Stress | Is this occurring during stress or emotional strain? |
| Cycle | Is there a recurring menstrual-cycle pattern? |
The aim is not to label every craving.
It is to see whether apparently random episodes form a repeatable pattern.
What Can You Do About Frequent Cravings?
Start with consistency rather than restriction.
Severe food restriction can itself intensify cravings.
Cleveland Clinic recommends nutritious eating patterns and reducing excess sugar and processed starches when managing insulin resistance.
Useful general principles may include:
- avoid repeatedly skipping meals if that leads to intense hunger later
- include protein in meals
- include fibre-rich foods
- choose minimally processed carbohydrate sources more often
- pair carbohydrates with protein, fibre or healthy fats
- reduce reliance on sugary drinks and highly refined snacks
- pay attention to sleep
- stay physically active
This is not about banning dessert.
It is about reducing the circumstances in which the body repeatedly moves from:
very hungry → quick-energy craving → short-term relief → hungry again
The goal is not to prove your willpower by resisting every sweet food. The goal is to create an eating pattern in which urgent cravings become less necessary.
When Are Cravings Worth Discussing With a Healthcare Professional?
Cravings alone rarely require metabolic testing.
But broader assessment may be reasonable when frequent cravings occur alongside:
- persistent increased hunger
- recurrent unexplained fatigue
- central weight gain
- acanthosis nigricans
- multiple skin tags
- PCOS
- previous gestational diabetes
- strong family history of type 2 diabetes
- borderline or abnormal glucose results
Cleveland Clinic notes that healthcare professionals evaluating insulin resistance may consider medical history, family history, physical findings and tests such as fasting plasma glucose, HbA1c and a lipid panel.
The important point is that testing decisions should be based on overall risk—not on a craving for chocolate.
Myths Worth Avoiding
Myth: “Craving sugar means I have insulin resistance.”
Fact: No. Sugar cravings are common and highly nonspecific.
Myth: “People with insulin resistance always crave sweets.”
Fact: No. Many people with insulin resistance have no symptoms, especially while the pancreas is still compensating.
Myth: “My cells are starving, so I must eat sugar.”
Fact: Appetite and cravings are controlled by complex metabolic and neurological signals. A craving itself does not prove that your cells lack glucose.
Myth: “All carbohydrates cause insulin resistance.”
Fact: Carbohydrate foods vary greatly. Whole grains, legumes, vegetables, fruits and minimally processed foods affect metabolism differently from frequent intake of highly refined carbohydrate foods and sugary drinks.
Myth: “The answer is to eliminate carbohydrates completely.”
Fact: Extreme restriction is not required for everyone and may be inappropriate. Sustainable meal quality, quantity and overall dietary pattern matter more.
Myth: “If I have good willpower, I should never crave food.”
Fact: Cravings are influenced by physiology, environment, sleep, stress, hormones and learned behaviour—not simply willpower.
Diafemme Perspective: A Craving Is Information, Not a Diagnosis
Women are often encouraged to treat cravings as a failure of discipline.
That is not particularly useful.
A craving may simply mean that a particular food is enjoyable.
It may reflect stress.
It may follow poor sleep.
It may occur predictably before menstruation.
Or it may be part of a pattern involving hunger, energy dips and metabolic dysfunction.
The craving itself cannot tell you which explanation is correct.
That is why the useful response is neither:
“My body wants sugar, so I must need sugar.”
nor:
“I crave sugar, therefore I am insulin resistant.”
Instead ask:
When does it happen? What came before it? What happens after it? And what else is happening in my health?
A craving is not a metabolic diagnosis. But a repeating craving pattern can be useful information.
Am I Insulin Resistant? — The 6-Part Series
Insulin resistance does not always announce itself with high blood sugar. Diafemme examines six possible clues—one at a time.
- Waist & Central Fat
- Skin Tags
- Acanthosis Nigricans
- Cravings — You are here
- Energy Crashes
- Cycle Issues
One clue is not a diagnosis. The purpose of this series is to help women recognize patterns worth discussing with an appropriate healthcare professional.
Frequently Asked Questions
Are sugar cravings a sign of insulin resistance?
They can occur in people with insulin resistance, but sugar cravings are highly nonspecific and are not considered a diagnostic sign. They become more interesting when they repeatedly occur alongside increased hunger, energy dips or other metabolic risk factors.
Why might insulin resistance make me feel hungry?
Increased hunger can occur when insulin resistance has progressed and blood glucose remains persistently elevated. Earlier insulin resistance may cause no obvious symptoms.
Why do I crave carbohydrates in the afternoon?
There are many possible reasons, including the composition and timing of previous meals, sleep, stress, habit and changes in energy regulation. A recurring afternoon pattern does not by itself establish insulin resistance.
Does craving chocolate mean my blood sugar is low?
No. A food craving cannot tell you whether your blood glucose is low. Symptoms and, when medically appropriate, glucose measurement are required to determine actual blood-glucose status.
Can insulin resistance exist if my fasting glucose is normal?
Yes. Early in insulin resistance, the pancreas may produce additional insulin to maintain glucose within the normal range.
Should I stop eating carbohydrates if I think I am insulin resistant?
Not automatically. Carbohydrate foods vary widely in nutritional quality and metabolic effect. Extreme dietary restriction should not be started solely because of cravings or suspected insulin resistance.
What foods may help me stay fuller for longer?
Meals containing adequate protein, fibre-rich foods and minimally processed carbohydrates may provide greater satiety and steadier energy than meals dominated by rapidly digested refined carbohydrates.
When should cravings make me consider metabolic testing?
Cravings alone usually do not justify testing. If they occur alongside persistent hunger, fatigue, central weight gain, PCOS, acanthosis nigricans, family history of diabetes or abnormal glucose results, discuss your overall risk with a healthcare professional.
Diafemme's Takeaway
Wanting something sweet does not mean you are insulin resistant.
Neither does enjoying bread, rice, chocolate or dessert.
The evidence connecting specific sugar cravings directly to insulin resistance is much less definitive than the evidence behind some of the earlier clues in this series.
But frequent, intense cravings may sometimes occur as part of a broader pattern involving:
hunger + energy dips + refined-carb cravings + other metabolic risk factors.
That pattern is worth noticing.
Not fearing.
Not diagnosing.
Not punishing with extreme restriction.
Notice when the craving happens.
Notice what you ate before it.
Notice your energy.
Notice your sleep, stress and cycle.
And consider what else your metabolic health may be telling you.
One craving tells you very little. A repeating pattern may tell you something worth investigating.
