The other night, my son called me and said he was cooking dinner.
Naturally, because I am his mother, one of my first questions was:
“What are you eating?”
Ground beef and rice.
Simple enough.
He had just made the rice in his rice cooker and was getting ready to eat with his roommate—who happens to be every bit as interested in health, wellness and biohacking as I am.
So I asked him another question.
“Wait. You’re eating the rice right now?”
Silence.
“Yes. Why?”
I was genuinely surprised.
“You’re not going to cool it first?”
That was followed by the predictable:
“What are you talking about?”
And just like that, we had our next AO Scan Global biohacking conversation.
Because sometimes the most interesting wellness strategies are not complicated.
They are sitting in your kitchen.
And this one may be as simple as:
Cook it. Cool it. Reheat it.
What happens next involves something called resistant starch.
And it is fascinating.
What Is Resistant Starch?
Most starch is broken down in the small intestine into glucose that can be absorbed and used for energy.
Resistant starch behaves differently.
As the name suggests, it is more resistant to digestion in the small intestine. Some of it travels farther through the digestive tract, where it can behave more like fermentable fiber.
There are several types of resistant starch.
The type that interests us here is commonly known as type 3 resistant starch, or RS3.
RS3 can form when certain cooked starchy foods are cooled.
Rice.
Potatoes.
Pasta.
Other cooked starches.
The process behind it is called starch retrogradation.
Don’t let the term make this sound complicated.
The concept is actually pretty simple.
When starch is cooked with water and heat, its structure changes.
As that cooked starch cools, portions of the starch molecules can begin reorganizing into a more ordered structure.
That reorganized starch can become more difficult for digestive enzymes to break down.
In other words:
The rice you eat tomorrow may not behave exactly the same way as the rice you eat straight out of the cooker tonight.
Same rice.
Different preparation.
Potentially different metabolic response.
Now we have my attention.
What Does the Research Say About Cooled Rice?
This is where this little kitchen biohack becomes much more interesting.
In a randomized crossover study published in the Asia Pacific Journal of Clinical Nutrition, researchers compared freshly cooked white rice with white rice that had been:
- cooked,
- cooled for 24 hours at approximately 4°C / 39°F,
- and then reheated before eating.
The freshly cooked rice contained approximately 0.64 grams of resistant starch per 100 grams.
The cooled-and-reheated rice contained approximately 1.65 grams per 100 grams.
Even more interesting, the cooled-and-reheated rice produced a lower glycemic response in the healthy adults participating in the study.
You can read the study through PubMed here.
Notice something important:
They reheated the rice.
So no—you do not necessarily have to stand over your refrigerator eating cold rice for breakfast in the name of biohacking.
The resistant-starch effect was still observed after reheating.
Does That Mean Cooled Rice Is a “Free Carb”?
No.
And this is where wellness information can go sideways very quickly on social media.
Cooling rice does not turn rice into broccoli.
It does not remove all of the carbohydrate.
It does not mean everyone will have the same glucose response.
And it certainly does not mean someone with diabetes or a metabolic condition should start changing meals or medication without understanding what is happening.
Another human study looked at cooled rice in people with type 1 diabetes and found a lower rise in post-meal glucose compared with freshly prepared rice.
But there was another finding that matters just as much:
Using the usual insulin dose with the cooled rice increased the risk of post-meal hypoglycemia.
That is an important reminder that a “biohack” can become clinically significant when medications are involved.
You can review that study here.
If you use insulin or glucose-lowering medication, changing the carbohydrate characteristics of a meal is something to discuss with your qualified healthcare professional.
The lesson is not:
Everyone should eat cooled rice.
The lesson is:
How food is prepared may change how that food behaves.
And that opens up a much bigger conversation.
Same Food. Different Information.
This is precisely the kind of thing that fascinates me about personalized wellness.
Two plates can look almost identical.
Same rice.
Same serving size.
Same calories on the label.
Yet preparation may change something about the starch structure before that food ever reaches your mouth.
Now zoom out.
What about:
Sleep the night before?
Exercise?
Stress?
Hydration?
Meal timing?
Protein eaten with the meal?
Fiber?
The order in which foods are eaten?
A walk afterward?
Your individual metabolic health?
Your microbiome?
Your nervous system?
Suddenly, “How many carbohydrates are in this?” starts looking like only one question among many.
And this is exactly where AO Scan becomes interesting to me.
Where AO Scan Fits Into This Conversation
First, let’s be very clear about what AO Scan is not.
AO Scan is not a continuous glucose monitor.
It is not a glucometer.
It is not an insulin assay.
It is not a laboratory blood test.
And an AO Scan value should never be interpreted as an actual blood glucose or insulin measurement.
AO Scan is an educational, non-diagnostic frequency wellness technology.
The technology looks across a remarkably broad collection of energetic data points and compares that information against blueprint frequencies to help users explore patterns within the body.
AO Scan evaluates information associated with more than 170,000 points throughout the body, compared against more than 120,000 blueprint frequencies.
That does not make AO Scan a replacement for laboratory medicine.
It gives us a different informational lens.
And that difference matters.
Start With the AO Scan Vitals Report
For this particular experiment, I would pay special attention to Vitals.
The AO Scan Vitals report organizes energetic information using familiar wellness and physiological terminology.
Within Vitals are categories that touch on areas related to:
- insulin response,
- glucose and carbohydrate metabolism,
- pancreatic function,
- digestive processes,
- metabolic regulation,
- nutritional factors,
- and other interconnected wellness values.
These are energetic readings, not clinical blood measurements.
That distinction cannot be overstated.
But what they can give an AO Scan user is something very interesting:
Another set of patterns to observe.
Then we can broaden the view with the other core AO Scan reports.
Comprehensive: Look Wider
The AO Scan Comprehensive report allows us to look beyond one metabolic term.
Because carbohydrate metabolism does not occur in isolation.
Think about everything potentially involved:
The pancreas.
Liver.
Digestive system.
Nervous system.
Circulation.
Cellular energy production.
Nutrients.
Minerals.
Hormonal signaling.
Stress response.
Mitochondrial function.
That is precisely why I am always far more interested in patterns than one isolated red, yellow or out-of-balance value.
One value can be interesting.
Several related values showing a similar energetic pattern become more interesting.
And when you begin repeating scans over time while changing specific lifestyle variables?
Now you are learning.
Body Systems: Step Back Even Further
The Body Systems report gives us another perspective.
Instead of becoming fixated on one value labeled “insulin” or “glucose,” we can ask:
What else is happening in related systems?
Is there a repeating energetic pattern involving digestion?
Pancreatic-related values?
Liver-related values?
Stress?
Nervous-system balance?
Nutritional patterns?
Energy metabolism?
The objective is not to diagnose a problem.
The objective is to become a more informed observer of your own wellness patterns.
And that brings me to the experiment I really want AO Scan users to try.
The Fresh Rice vs. Cooled Rice AO Scan Experiment
Here is where this becomes fun.
Pick two relatively similar days.
On Day One, prepare a meal containing freshly cooked rice.
Before eating, run the AO Scan reports you want to compare.
Then eat your meal.
At a consistent time afterward, scan again.
Save your results.
Don’t panic about one value.
Don’t start diagnosing yourself.
Just observe.
Then, on another comparable day, repeat the experiment.
This time:
Cook the same type of rice ahead of time.
Cool it safely in the refrigerator for approximately 24 hours.
Reheat it.
Try to use approximately the same serving size.
Pair it with a similar meal.
Scan at approximately the same times.
Then compare.
What changed?
What stayed the same?
Did related energetic values move together?
Do you see anything worth repeating?
This is where AO Scan becomes a fascinating tool for the curious biohacker.
Not because it proves what your blood sugar did.
But because it encourages you to change one variable, observe, repeat and look for patterns.
And that is a very different way of moving through your wellness journey.
Make the Experiment Better by Controlling the Obvious Variables
If you really want to learn something from your own experiment, don’t change twelve things at once.
That is not biohacking.
That is chaos with a wellness label.
Try to keep the two meals as similar as reasonably possible.
Use:
- the same type of rice
- approximately the same serving size
- the same or similar protein
- similar added fats and sauces
- similar meal timing
- similar AO Scan timing
- similar hydration
- similar caffeine intake
- similar activity before and after the meal
And pay attention to sleep and stress.
If you slept nine hours before one experiment and four hours before the other, that matters.
If one meal follows a peaceful Sunday morning and the other follows three cups of coffee and an argument before lunch, that matters too.
The point is not to create a perfect laboratory in your kitchen.
It is simply to avoid changing so many variables that you have no idea what you are actually observing.
Then repeat it.
One comparison is interesting.
A repeated pattern is much more interesting.
Want an Even Better Experiment? Add a Glucose Meter or CGM
This is where we can combine tools without confusing what any one tool actually does.
If you already use a continuous glucose monitor or a validated blood-glucose meter, you could observe your actual glucose response alongside your AO Scan energetic patterns.
Now we have two completely different types of information.
The glucose monitor answers:
What happened to my measured glucose?
AO Scan invites another question:
What energetic patterns am I seeing across the broader wellness picture?
Those are not interchangeable.
They do not need to be.
One of the biggest mistakes in wellness is insisting that every technology answer the same question.
Different tools can provide different information.
Use each for what it actually does.
That is smart biohacking.
The Gut Gets Involved Too
Resistant starch is interesting for another reason.
Because it resists digestion in the small intestine, more of it can reach the colon, where gut microbes can ferment it. Research has linked resistant starch intake with changes in the gut microbiome and the production of short-chain fatty acids, including butyrate.
That opens an entirely different wellness conversation.
We started with:
What happens to my blood sugar after rice?
Now we are also talking about:
- digestion
- the microbiome
- fermentation
- short-chain fatty acids
- the intestinal environment
- metabolic signaling
This is exactly why I resist looking at nutrition as though one food has one job.
The body does not work like that.
Neither should our wellness thinking.
And Yes, This Is Where Food Preparation Gets Fascinating
Think about what just happened.
The ingredient did not change.
The rice was still rice.
But time and temperature changed the physical structure of some of its starch.
That is such a beautifully simple example of why food is more than the number printed next to “carbohydrates” on a nutrition label.
Preparation matters.
Cooking matters.
Cooling matters.
Pairing foods matters.
Movement matters.
And the person eating the food matters.
This is why I want people to become curious rather than fearful.
I don’t want you staring at a bowl of rice thinking:
CARBS!
I want you asking:
What happens when I prepare this differently?
That is a much more useful question.
Another Biohack: What You Do After the Meal Matters Too
There is another piece to this metabolic puzzle that we recently explored at AO Scan Global.
Movement after eating.
Research suggests that light-to-moderate walking after meals can reduce post-meal glucose excursions for many people, in part because contracting skeletal muscle can increase glucose uptake through pathways that are not entirely dependent on insulin. Our recent AO Scan Global article walks through the science and the AO Scan connection in detail.
Read it here:
Walking After Meals: What Blood Sugar, AGEs, and AO Scan Patterns Can Teach Us
Now put the ideas together.
What if you compared:
Freshly cooked rice + sitting after dinner
with
Cooled/reheated rice + a short walk afterward
Or better yet, don’t change both variables at once.
Test them independently.
That is how you begin figuring out what may matter for you.
Fresh rice versus cooled rice.
Walking versus sitting.
Earlier meal versus later meal.
More protein versus less.
Better sleep versus poor sleep.
Change one thing.
Observe.
Repeat.
This is how wellness becomes personal instead of theoretical.
Food Safety: Please Don’t Turn This Biohack Into Food Poisoning
This section matters.
Cooked rice should not sit around on the kitchen counter for hours while you wait for it to cool.
Cooked rice can be associated with Bacillus cereus, a bacterium whose spores may survive cooking and create food-safety problems when cooked rice is improperly held or cooled. FDA guidance identifies cooked rice among foods where Bacillus cereus survival and toxin formation can be a concern.
For home food safety, the FDA recommends refrigerating perishable cooked foods within two hours and using shallow containers to help leftovers cool more quickly. Keep the refrigerator at 40°F/4°C or below.
When reheating leftovers, USDA guidance recommends heating them to 165°F/74°C.
My simple rice routine:
Cook it.
Portion it into a shallow container.
Get it refrigerated promptly.
Let it chill.
Reheat it thoroughly when you’re ready to eat it.
Then enjoy your experiment.
This is not the place for the “I’ve left rice on the counter overnight my whole life and I’m fine” school of research.
We have better information than that.
Use it.
What About Potatoes and Pasta?
Rice gets a lot of attention because it has been studied specifically, but the underlying concept of retrograded resistant starch is not exclusive to rice.
Cooling cooked starches such as potatoes and pasta can also change portions of their starch structure.
But this is important:
Do not assume every starch, every cooking method and every person will produce the exact same result.
Different foods contain different proportions of amylose and amylopectin.
Varieties differ.
Cooking methods differ.
Cooling time matters.
Reheating matters.
Meal composition matters.
And human metabolism varies.
That is why I keep coming back to the same idea.
Observe your patterns instead of blindly copying someone else’s.
This Is the Kind of Biohacking I Love
Biohacking gets unnecessarily complicated sometimes.
People hear the word and imagine:
expensive chambers,
twenty-seven supplements,
wearables on every limb,
a refrigerator full of peptides,
and a morning routine that requires three hours and a personal assistant.
Sometimes biohacking is much simpler.
Sometimes it is:
Cook tonight’s rice for tomorrow.
That is it.
A tiny change.
Backed by an interesting physiological mechanism.
Supported by human research.
Easy enough for almost anyone to understand.
Then, if you’re an AO Scan user like me, you have another layer:
Scan and observe.
That is my kind of experiment.
What AO Scan Can—and Cannot—Tell You About Insulin Response
I want to circle back to this because the terminology inside AO Scan can be very compelling.
When you see familiar words associated with insulin, glucose metabolism, pancreas-related functions, nutrients or metabolic processes inside an AO Scan report, it can be tempting to interpret them exactly as you would a laboratory result.
Don’t.
An AO Scan value labeled with familiar physiological terminology is not the same thing as a laboratory measurement of that substance or function.
If you need to know:
- fasting glucose
- fasting insulin
- hemoglobin A1C
- oral glucose tolerance
- actual post-meal glucose
- clinical insulin resistance
there are established medical tests for those questions.
Use them when appropriate.
What AO Scan gives us is an opportunity to explore educational energetic information and repeating patterns across a very broad wellness picture.
And because the reports can be repeated, we can ask better questions over time.
That is where I believe its value becomes so fascinating.
What About Epigenetics and AO Scan?
You will sometimes hear the word epigenetics in personalized-wellness conversations.
At its simplest, epigenetics is part of the science of how environmental and behavioral influences can affect the regulation of gene activity without changing the underlying DNA sequence itself.
Food choices.
Exercise.
Sleep.
Stress.
Environment.
These are all examples of inputs that can influence physiology over time.
But AO Scan is not an epigenetic laboratory test.
It does not measure DNA methylation or directly measure gene expression.
I think the useful connection is this:
AO Scan can encourage you to look at the lifestyle inputs you actually control.
Instead of seeing an energetic pattern and becoming afraid of it, ask:
What is this prompting me to pay attention to?
Maybe it is food.
Maybe movement.
Maybe hydration.
Maybe stress.
Maybe sleep.
Maybe nutrients.
Maybe it is simply telling you to investigate further with appropriate clinical testing.
Those are the kinds of educational wellness suggestions that can move us toward making better-informed choices.
And ultimately, that is what I mean when I talk about helping the body move toward homeostasis.
Not forcing it.
Supporting it.
Stop Looking for the Perfect Number
This may be one of the most important lessons for new AO Scan users.
Please do not chase every single number.
The body is dynamic.
Your energetic field is dynamic.
You are responding all day long to food, light, thoughts, movement, hydration, sleep, people, environment, stress and countless other inputs.
One unusual value is not a verdict.
One scan is not your identity.
And one meal is not your destiny.
Look for patterns.
Look for repetition.
Look at related areas.
Then ask better questions.
That is a much healthier relationship with wellness technology.
A Simple Resistant Starch Experiment to Save
Here is the entire experiment in one place.
Day 1: Fresh Rice
- Choose a normal meal containing freshly cooked rice.
- Keep the portion reasonable and record approximately how much you ate.
- Run the AO Scan reports you want to compare.
- Eat.
- Repeat the same reports at a consistent post-meal interval.
- Save the results.
- Record how you actually feel.
Day 2: Cooled & Reheated Rice
- Use the same type of rice.
- Cook it ahead.
- Refrigerate it safely for approximately 24 hours.
- Reheat it thoroughly.
- Use a similar portion and meal.
- Scan at approximately the same times.
- Save the results.
- Record how you feel.
Then Ask:
- Did anything repeat?
- Were there noticeable differences?
- Did related metabolic or digestive themes move together?
- Did your energy feel different?
- Hunger?
- Fullness?
- Brain fog?
- Sleepiness?
- Cravings?
- How did you feel two or three hours later?
If you have a CGM or glucose meter, you can compare your actual glucose data too.
Then repeat the experiment another day.
Scan. Observe. Repeat.
Not because one experiment proves anything.
Because curiosity creates better questions.
The Bigger Metabolic Picture
This conversation started with rice.
But resistant starch is really just the doorway.
It teaches us that the body responds not only to what we eat but also potentially to:
- how food is prepared,
- what we pair it with,
- when we eat it,
- how much we eat,
- what we do afterward,
- how well we slept,
- and the metabolic state we brought into that meal.
That is a lot more interesting than labeling foods simply “good” or “bad.”
And it is much closer to how the body actually behaves.
Frequently Asked Questions
Does cooling rice really increase resistant starch?
Research shows that cooling cooked rice can increase resistant starch. In one randomized crossover study, white rice cooled for 24 hours at approximately 4°C/39°F and then reheated had higher resistant starch content than freshly cooked rice and produced a lower glycemic response in healthy adults.
Can I reheat the rice?
Yes. The human rice study discussed in this article specifically tested rice that had been cooled and then reheated.
How long should rice be cooled for resistant starch?
The rice study highlighted here used 24 hours of refrigeration at approximately 4°C/39°F. That does not mean 24 hours is the only possible preparation method, but it gives us a studied protocol rather than an internet guess.
Does cooled rice lower blood sugar?
Some human studies have found a lower post-meal glycemic response with cooled or cooled-and-reheated rice compared with freshly cooked rice. Individual responses vary, and people who use insulin or glucose-lowering medication should take particular care because altering meal glycemic response may affect medication needs.
Does AO Scan measure blood sugar?
No. AO Scan does not measure blood glucose, insulin, A1C or other clinical metabolic biomarkers. It provides educational frequency-based wellness information.
Can AO Scan show insulin resistance?
AO Scan may display energetic information using terminology associated with insulin, metabolic processes, the pancreas and other body systems, but those values are not a diagnosis of insulin resistance. Clinical concerns require appropriate medical testing.
Is resistant starch good for the gut?
Resistant starch can reach the colon and be fermented by gut microbes. Research has linked resistant starch with changes in microbiome activity and short-chain fatty-acid production, including butyrate. Effects vary among individuals and resistant-starch types.
Is cold rice safe?
Rice should be cooled and stored safely. Refrigerate cooked food promptly, use shallow containers for faster cooling, keep your refrigerator at 40°F/4°C or below, and reheat leftovers thoroughly to 165°F/74°C.
Curious? Scan It.
This is why I love AO Scan.
It inspires curiosity.
It reminds us that wellness is not one static snapshot.
It gives us a reason to pay attention.
And when we combine that curiosity with legitimate research, good nutrition, movement, sleep, appropriate medical testing when needed, and a willingness to experiment intelligently?
Now we are doing something useful.
Maybe tonight you eat the rice straight from the cooker.
Maybe tomorrow you cool it first.
Maybe you compare.
Maybe you notice absolutely nothing.
Or maybe something makes you stop and say:
Huh. That’s interesting.
Either way, you learned something.
And that is always a good place to begin.
