When most people think about gout, they immediately think about purines.
They think about red meat, seafood, beer, and all the foods they’ve been told to avoid. I’ve lived with gout for many years, and I’ve learned that diet certainly matters. But I’ve also learned that gout is much more complicated than simply eating too many high-purine foods.
One area that deserves much more attention is insulin resistance.
Researchers have found a strong relationship between insulin resistance, high uric acid, gout, obesity, high blood pressure, and other metabolic conditions. In fact, understanding insulin resistance may help explain why gout so often appears alongside these other health problems.
So let’s take a closer look at what insulin resistance actually means and why I believe people living with gout should know about it.
What Is Insulin Resistance?
Insulin is a hormone made by your pancreas. One of its main jobs is helping glucose, or sugar, move from your bloodstream into your cells, where it can be used for energy.
Think of insulin like a key that helps unlock the door to your cells.
When you become insulin resistant, your cells don’t respond to insulin as efficiently as they should. Your pancreas then has to produce more insulin to get the job done.
For a while, your blood sugar might still appear normal because your pancreas is compensating by producing extra insulin.
That’s an important point: you can have insulin resistance before you develop type 2 diabetes.
Over time, insulin resistance can contribute to higher blood sugar and is closely connected with metabolic syndrome, excess abdominal fat, abnormal cholesterol or triglycerides, and high blood pressure.
And this is where gout enters the picture.
What Does Insulin Have to Do With Uric Acid?
Your kidneys play a major role in controlling the amount of uric acid in your bloodstream.
Uric acid is created when your body breaks down purines. Normally, much of that uric acid travels through your bloodstream to your kidneys, where it can eventually leave your body in urine.
But insulin resistance may interfere with that process.
A study involving 133 people with gout found that greater insulin resistance was associated with less efficient kidney clearance of uric acid. The researchers concluded that insulin resistance and the kidneys’ handling of sodium may help explain why hyperuricemia is frequently associated with conditions such as hypertension and diabetes.
Put simply:
Insulin resistance → higher insulin levels → kidneys may excrete less uric acid → uric acid can build up in the blood.
When uric acid remains high enough, monosodium urate crystals can form in and around joints. Your immune system’s reaction to those crystals is what produces the intense inflammation and pain of a gout flare.
For me, this is one of the most interesting pieces of the gout puzzle.
Is It a Two-Way Street?
Here’s where things become even more interesting.
Scientists are investigating whether the relationship could work in both directions.
We have evidence suggesting that insulin resistance can make it more difficult for the kidneys to eliminate uric acid. But researchers are also investigating whether elevated uric acid itself might contribute to insulin resistance through mechanisms involving oxidative stress, inflammation, blood vessel function, and insulin signaling.
A review of the evidence described insulin resistance and hyperuricemia as potentially having a bidirectional relationship.
However, I want to be careful here.
Association doesn’t automatically prove causation. Researchers are still trying to determine exactly how much elevated uric acid contributes to insulin resistance in humans, and reviews of the evidence acknowledge that the causal relationship remains controversial.
So I wouldn’t say that gout causes insulin resistance or that insulin resistance alone causes gout.
What I would say is that these conditions are interconnected enough that we shouldn’t look at gout in isolation.
The Metabolic Syndrome Connection
Another term people with gout should know is metabolic syndrome.
Metabolic syndrome isn’t one disease. It’s a group of metabolic risk factors that tend to occur together, including problems such as:
- Abdominal obesity
- High blood pressure
- High blood sugar
- High triglycerides
- Low HDL cholesterol
Insulin resistance is thought to play an important role in this metabolic picture.
This helps explain something I’ve discussed many times over the years: gout isn’t simply a joint problem.
The painful joint may be what gets our attention, but high uric acid frequently exists alongside broader metabolic health issues.
That’s why I believe someone living with gout shouldn’t focus exclusively on whether yesterday’s steak contained too many purines.
We need to look at the bigger picture.
Sugar and Fructose Deserve Attention
If we’re talking about insulin resistance and gout, we also have to talk about sugar.
I’m particularly cautious about sugar-sweetened beverages.
Fructose is metabolized differently from other carbohydrates and can increase uric acid production. Regularly consuming large amounts of sugary drinks can also make it easier to consume excess calories and gain weight, which can further contribute to poor metabolic health.
The American College of Rheumatology’s gout guideline conditionally recommends limiting high-fructose corn syrup for people with gout.
This doesn’t mean someone with gout can never eat something sweet.
Personally, I think that’s the wrong way to approach a sustainable gout diet.
Instead, I’d pay particular attention to where large amounts of added sugar are sneaking into your diet—soft drinks, energy drinks, sweetened coffees, desserts, candy, and heavily processed foods are obvious places to look.
What About Losing Weight?
Weight is another important part of this discussion, but it needs to be approached carefully.
Being overweight or obese is associated with gout, insulin resistance, and metabolic syndrome. For people with gout who are overweight or obese, the American College of Rheumatology conditionally recommends a weight-loss program.
Interestingly, the guideline cites research in which changes in body weight were associated with recurrent gout flares. A greater than 5% decrease in BMI was associated with 40% lower odds of recurrent flare compared with people whose weight remained relatively stable. However, the guideline rates the overall certainty of evidence surrounding weight-loss interventions for gout as very low.
So I wouldn’t look for a crash diet.
I’d focus on sustainable habits.
Losing weight gradually when appropriate, becoming more active, eating better-quality foods, and improving your overall metabolic health makes far more sense to me than chasing another extreme diet.
Exercise Is About More Than Burning Calories
Exercise is another tool worth discussing because physical activity can help improve insulin sensitivity.
That doesn’t mean you need to become a marathon runner.
Walking, cycling, swimming, resistance training, and other activities you enjoy can all be part of an active lifestyle.
During an active gout flare, of course, I wouldn’t try to push through severe pain in an affected joint. Resting that joint and following your healthcare provider’s treatment plan is more sensible.
But between attacks, regular movement can be an important part of looking after your overall metabolic and cardiovascular health.
I like to think of exercise as something I’m doing for my entire body—not simply as a way to burn calories.
What I Would Focus On
If I were trying to improve both my gout management and metabolic health, I wouldn’t obsess over one individual food.
I’d concentrate on the pattern of my lifestyle.
I’d eat plenty of vegetables and whole plant foods, choose high-fiber carbohydrates, watch my intake of sugary beverages and heavily processed foods, stay hydrated, maintain an appropriate body weight, exercise regularly, moderate alcohol, get enough sleep, and continue monitoring my uric acid.
And if I’ve been prescribed uric-acid-lowering medication, I wouldn’t replace it with diet or exercise.
This is particularly important because lifestyle changes usually produce relatively modest changes in serum uric acid compared with medication. The American College of Rheumatology specifically notes that dietary changes generally have only a small effect on serum urate, even though certain foods and drinks can still act as flare triggers.
For many people with gout, medication and lifestyle aren’t competing strategies.
They work together.
Should You Get Checked for Insulin Resistance?
If you have gout—particularly if you also have excess abdominal weight, high blood pressure, high triglycerides, abnormal blood sugar, or a family history of type 2 diabetes—I think it’s worth discussing your metabolic health with your healthcare provider.
That doesn’t necessarily mean asking for one particular insulin-resistance test.
Your doctor may evaluate fasting glucose, A1C, blood pressure, cholesterol, triglycerides, waist circumference, and other factors depending on your individual situation.
The important thing is not to assume that because your gout is under control, everything else is automatically fine.
My Takeaway
After living with gout and researching this disease for years, one lesson keeps coming back to me:
Gout is about much more than purines.
Yes, what we eat matters. Alcohol matters. Hydration matters. Genetics matter. Kidney function matters.
But metabolic health matters too.
Insulin resistance may make it harder for the kidneys to efficiently eliminate uric acid, while high uric acid and insulin resistance frequently exist alongside obesity, high blood pressure, diabetes, and metabolic syndrome. Researchers are also continuing to investigate whether the relationship between uric acid and insulin resistance goes both ways.
That’s why I don’t believe the answer to living well with gout is simply memorizing a list of high-purine foods.
I prefer to look at the entire picture: manage your uric acid, improve the quality of your diet, stay active, maintain a healthy weight, monitor your metabolic health, and work with your healthcare provider on the treatment plan that’s right for you.
Your big toe might be where gout gets your attention.
But what is happening throughout the rest of your body deserves attention too.
