Brown rice has gained popularity in recent years as a nutritious alternative to white rice. With its nutty flavor, chewy texture and abundance of fiber, vitamins and minerals, brown rice has become a staple for many health-conscious eaters looking to improve their diets. But can brown rice be part of a low-carb diet? Let’s take a closer look.
What is brown rice?
Brown rice is a whole grain that has only the outermost layer, the hull, removed during processing. This leaves the nutrient-dense bran and germ of the rice kernel intact. The bran contains beneficial fiber, vitamins, minerals and phytonutrients. The germ includes healthy fats, B vitamins, minerals, antioxidants and various phytochemicals.
On the other hand, white rice has both the hull and bran layers removed, stripping away most of the fiber, vitamins and minerals. While white rice is enriched with some B vitamins and iron, it does not provide the same robust nutritional profile as brown rice.
Some key differences between brown and white rice:
| Nutrient | Brown Rice | White Rice |
|---|---|---|
| Fiber | 3.5g per cup cooked | 0.6g per cup cooked |
| Magnesium | 84mg per cup cooked | 19mg per cup cooked |
| Phosphorus | 162mg per cup cooked | 53mg per cup cooked |
| Selenium | 19mcg per cup cooked | 15mcg per cup cooked |
As you can see, brown rice outshines white rice when it comes to nutritional value.
Carb content of brown rice
So what about the carb content of brown rice? Here is the breakdown for a 1 cup serving of cooked brown rice:
- Total carbohydrates: 44g
- Dietary fiber: 3.5g
- Sugars: 0.9g
- Starch: 39.6g
Brown rice is high in carbohydrates, providing nearly 45g per cup. However, it contains 3.5g of dietary fiber. Fiber is a type of carbohydrate that our bodies cannot digest. So we can subtract the fiber grams from the total carbs to determine the net carb content.
The resulting net carbs in a 1 cup serving of brown rice is approximately 40g. Compared to white rice which provides about 45g net carbs per cup, brown rice is slightly lower. But it still contains a substantial amount of digestible carbohydrates.
Glycemic index of brown rice
Another factor to consider is the glycemic index (GI). This measures how quickly a food raises blood sugar levels. Foods are ranked on a scale of 0 to 100.
Brown rice has a GI of 50, which is considered a medium GI food. This means it can raise blood sugar more moderately than a high GI food like white rice (GI of 73).
However, GI doesn’t tell the whole story. We also have to look at the glycemic load (GL). GL factors in the amount of carbohydrates consumed. While brown rice may have a lower GI than white rice, a 1 cup serving still provides a GL of 20 which is considered high (above 10 is high).
So brown rice is not a low glycemic food and will still cause a noticeable spike in blood sugar for most people. Those with diabetes need to be mindful of portion sizes.
Is brown rice keto-friendly?
The ketogenic diet is a very low carb, high fat diet. It puts the body in a state of ketosis, relying on fat and ketones for energy instead of glucose from carbohydrates.
Keto macros often call for limiting carbs to just 20-50g per day. Some people can remain in ketosis with carb intake up to 50g, while others need to restrict to 20-30g.
With 40g net carbs per cup, brown rice would use up most of the daily carb allowance on keto. A 1 cup serving would make it very tough to stick to keto macros and remain in ketosis.
The high glycemic load is another strike against brown rice for keto. Even small amounts could disrupt ketosis by spiking blood sugar and insulin.
Can brown rice fit into a low carb diet?
Low carb diets have a broader range of carb intake than keto. They typically call for 100-150g of carbs per day. Some people can go up to 200g daily and still benefit from reduced carbs.
Within these carb ranges, small servings of brown rice may be included in a low carb eating pattern. A ??????? cup serving provides about 20g net carbs. This moderate portion can fit into a low carb day, but timing matters.
It’s best to pair brown rice with a protein like chicken, fish or eggs. This helps slow digestion and prevents blood sugar spikes.
Eating brown rice later in the day may work well for those who are more active in the morning and early afternoon. The carb energy can be utilized during and after exercise.
Going over about 150g of carbs daily tends to take someone out of the low carb range. So portions of brown rice should still be monitored.
Benefits of brown rice on a low carb diet
Here are some potential benefits of incorporating modest amounts of brown rice into a low carb eating plan:
More nutrients
Brown rice provides nutrients like magnesium, phosphorus, selenium, and various B vitamins. These support energy levels, metabolism, nerve function, and cell repair. White rice lacks many of these nutrients.
More fiber
Brown rice is rich in insoluble fiber from the bran. This improves digestive health, keeps you full, and feeds beneficial gut bacteria.
Better gut microbiome
Beyond fiber content, research suggests compounds in brown rice may support a healthier gut microbiome compared to white rice.
Lower GI benefits
With a lower GI than white rice, brown rice in small portions may help stabilize blood sugar when eaten with protein, fat, veggies and fiber.
Satisfies cravings
The fiber, nutrients and nutty taste of brown rice can satisfy cravings for comfort foods. This makes it easier to stick to low carb goals.
Adds variety
For those missing grains on a low carb diet, brown rice can provide variety to enjoy occasionally. This adds flexibility and sustainability to the eating pattern.
Potential downsides of brown rice on a low carb diet
Here are a few drawbacks to keep in mind with brown rice on a low carb eating plan:
High net carbs
Brown rice is not a low carb food. Moderate portions are required to keep net carbs in check. It can easily add up to too many carbs if overeaten.
Can cause cravings
Eating foods that spike blood sugar may perpetuate carb cravings. Some find avoiding rice and grains helps control appetites.
May cause digestive issues
The extra fiber in brown rice could cause gas, bloating or loose stools, especially when transitioning from a low fiber diet. Slowly increasing fiber intake helps minimize problems.
Prep time
Preparing brown rice takes more time than white varieties. The extra cooking time and planning required could be a drawback for some people.
Glycemic impact
Despite having a lower GI than white rice, brown rice still provides a high GL. Small portions are needed to prevent reactive hypoglycemia.
Potential arsenic concerns
Brown rice contains trace levels of arsenic, a toxic heavy metal. White rice tends to be lower. Exposure should be limited.
Tips for fitting brown rice into a low carb diet
Here are some suggestions for incorporating brown rice:
– Measure exact serving sizes with a food scale or measuring cups to control portions
– Limit to 1-2 servings per week max to keep net carbs in check
– Always pair with protein, fat or veggies to stabilize blood sugar response
– Choose boiled, steamed or toasted rice over fried varieties
– Time carb intake around activity and exercise for better energy utilization
– Select organic, low-arsenic brown rice when possible
– Experiment with alternative whole grains like quinoa or farro for more variety
– Be mindful of overall daily carb tally with rice added to the menu
– Monitor cravings and hunger levels. Adjust portions if needed.
– Watch for any digestive upset and reduce intake if necessary

The bottom line
While brown rice cannot be considered a low carb food, incorporating 1-2 moderate servings per week may work for some following a low carb diet. Paying attention to portion sizes, timing, and overall daily carb totals allows brown rice to be enjoyed in a low carb eating pattern. It provides more nutrients, fiber and satisfaction compared to refined grains.
However, those adhering to a strict keto diet should avoid brown rice. Even small amounts could make it difficult to maintain ketosis. People vary in terms of carb tolerance, so finding the right balance is key. As with any change to your diet, keep an eye on how you feel and adjust as needed to optimize health.
