One cup of cooked brown rice contains 218 calories. That’s based on a standard serving of 195 grams, with the rice cooked in plain water without added oil or butter. If you’re measuring by weight rather than volume, 100 grams of cooked brown rice comes to about 112 calories.
Full Nutrition Breakdown Per Cup
Most of those 218 calories come from carbohydrates. A single cup of cooked brown rice delivers 45.8 grams of total carbohydrates, 3.5 grams of dietary fiber, and 1.6 grams of fat. The protein content sits around 5 grams.
Where brown rice really stands out is in its micronutrient profile. One cup provides nearly 100% of your daily value for manganese, a mineral involved in bone health and metabolism. You also get about 30% of your daily phosphorus and 25% of your daily magnesium. These minerals are concentrated in the bran layer, the outer coating that gets stripped away when rice is milled into white rice.
How Brown Rice Compares to White Rice
Calorie-wise, brown and white rice are surprisingly close. A cup of cooked white rice has roughly 205 calories compared to brown rice’s 218. The real difference is in what comes along with those calories. Brown rice retains its bran and germ layers, which carry more fiber, more minerals, and more B vitamins. White rice loses most of that during processing.
Brown rice also has a lower glycemic index. Harvard Health Publishing rates it at 68, placing it in the “medium” category, while white rice typically lands in the high range around 72 to 73. That means brown rice raises blood sugar somewhat more gradually, though the difference is moderate rather than dramatic.
Does Brown Rice Keep You Fuller?
The extra fiber in brown rice does appear to increase feelings of fullness compared to white rice. Research published in the Philippine Journal of Crop Science found that satiety scores tended to be higher after eating brown rice, and that this effect correlated with its higher fiber content. The fiber slows glucose release after a meal, which can help sustain energy levels.
That said, the practical impact on how much you eat afterward may be limited. The same study found that despite feeling fuller, participants ate similar amounts of food two hours later regardless of whether they’d had brown or white rice. The extra 2 to 3 grams of fiber in brown rice may not be enough on its own to significantly reduce subsequent calorie intake. Pairing rice with protein, vegetables, or healthy fats will do more for satiety than the rice type alone.
How Cooking Method Changes the Count
The 218-calorie figure assumes you’re cooking brown rice in plain water. Adding oil, butter, or broth during cooking increases the calorie count, sometimes substantially. A single tablespoon of olive oil adds about 120 calories to your pot. Coconut milk, a common addition in many recipes, can add 50 to 80 calories per serving depending on how much you use. If you’re tracking calories carefully, stick with water and season after cooking so you can measure additions precisely.
It’s also worth noting the difference between raw and cooked measurements. Dry brown rice is much more calorie-dense per gram because it hasn’t absorbed water yet. One cup of dry brown rice yields roughly three cups cooked. If a recipe lists rice quantities in dry measurements, multiply the serving size accordingly to get an accurate calorie count.
Serving Size in Practice
One cup of cooked rice is a generous serving, roughly the size of a baseball or a tightly packed fist. Many restaurants serve portions closer to 1.5 or 2 cups, which would put you at 327 to 436 calories from rice alone. If you’re eating brown rice as a side dish, half a cup (about 109 calories) is a reasonable portion that leaves room on your plate for protein and vegetables. For a grain bowl where rice is the base, a full cup is standard.
