Fried rice vs white rice
Swap one for the other at the same meal on different days. In our members, the typical rise was 2.0 mmol/L for fried rice and 1.8 for white rice.
We looked at Vively members who ate fried rice on its own while wearing a glucose sensor. Here is what happened, how it compares, and how to find out what it does to you.
Half of members rose between 1.3 and 2.9 mmol/L.
Short answer: Fried rice raised blood sugar by a typical 2.0 mmol/L in 263 Vively members who wore a continuous glucose monitor (CGM) and logged it on its own. The middle half of members rose between 1.3 and 2.9 mmol/L. Frying the rice in oil didn't lower the rise: fried rice rose a little more than plain white rice.
When you eat carbohydrate, your body breaks it down into glucose and your blood glucose rises. That is normal, because glucose is your body’s main fuel. Insulin then moves it out of your blood and into your cells, and your level comes back down.
A big rise is sometimes followed by a dip below where you started. In a study of 1,070 people, those with bigger dips after breakfast felt hungrier sooner and ate more over the rest of the day.
Bigger, more frequent rises mean your body releases more insulin. If your cells stop responding well to it (insulin resistance), your body has to make even more. Insulin resistance usually builds for 10 to 15 years before a standard glucose blood test picks it up.
Studies of people without diabetes have linked higher glucose levels, including two hours after a sugary drink, with a higher risk of heart disease. Higher rises after meals are also often one of the first changes on the way to type 2 diabetes.
Glucose is meant to go up after you eat. What matters is your pattern over weeks: how high you go, how often, and how quickly you come back down. That pattern is personal, so measuring it beats guessing.
If you have diabetes or take medicine that lowers glucose, talk to your doctor before changing how you eat.
Two groups of members in the Sydney and Melbourne time zones, each eating one food on its own: 140 for fried rice and 328 for white rice. These are their average curves. Drag across a chart to read it.

typical rise in mmol/L, fried rice vs white rice
Average curves look gentler than any one person’s, because people peak at different times. These are different groups of people, so treat it as a guide, not a verdict.
22% barely moved. After fried rice on its own, 22% of members rose less than 1 mmol/L and 36% rose 2.5 or more. Which group are you in?
Test it on yourselfLine up 263 members from smallest to biggest typical rise after fried rice, then pick ten people evenly spaced along the line. Same food, very different curves.
barely moved, with a typical rise under 1.0 mmol/L
rose 2.5 mmol/L or more
Fried rice is white rice stir-fried with oil, egg, vegetables and sauce. People often expect the oil and egg to slow the rise, but the rice is still the main ingredient, and takeaway serves are large.
Members' curves peaked around 45 minutes after eating and stayed raised for a while, similar to sushi.
Portion size, what you ate earlier, sleep, stress, movement and your menstrual cycle all change the curve too. That is why we built Vively around testing your own meals instead of handing out food lists.

Averages only get you so far. These are the tests our members run with their sensors.
Swap one for the other at the same meal on different days. In our members, the typical rise was 2.0 mmol/L for fried rice and 1.8 for white rice.
Ask for extra vegetables and egg with a smaller serve of rice, or share a takeaway serve.
After the same meal, sit one day and take a 10-minute walk the next. Compare how high you go.
Wear a CGM with Vively and see the rise, the peak and the recovery for every meal you log. Then try a swap and compare the two curves side by side.
Get your CGM
In our data, yes. 263 Vively members wearing a CGM rose a typical 2.0 mmol/L after fried rice, slightly more than after plain white rice (1.8). The middle half of members rose between 1.3 and 2.9 mmol/L.
Not in our members. The oil and egg in fried rice didn't bring the typical rise below plain white rice. Portion size is likely a bigger factor, because takeaway fried rice is usually a large serve.
Cooling cooked rice can turn some starch into resistant starch, which digests more slowly. Studies have found modest effects, and we can't see from our data whether members' fried rice was made from leftovers. A CGM is a good way to test it for yourself.
There is no official cut-off for a spike in people without diabetes. In a 2019 study of healthy adults who wore CGMs, glucose stayed between 3.9 and 7.8 mmol/L for about 96% of the day. Rises after meals are normal. How high you go, how long you stay there and your pattern over weeks matter more.
We used meals logged in the Vively app by members wearing a CGM between January 2022 and October 2026, leaving out members who told us they have type 2 diabetes, and our own staff. The rise is the highest reading in the two hours after eating, minus the member’s average for the four hours before. If glucose fell, we counted the rise as zero. We took each member’s own median first, then the median across members. “On its own” means the food was the only item logged for that meal. The curves use members in the Sydney and Melbourne time zones, meals since January 2023 and each member’s three most recent meals of each kind. Data is de-identified and only shown when at least 30 members contribute. This is observational app data, not a controlled GI test, and portions vary.
