Among common rice varieties, long-grain white rice is one of the lower-calorie options at about 205 calories per cooked cup, while short-grain white rice comes in higher at roughly 270 calories for the same amount. But the real winner depends on whether you’re comparing traditional rice varieties or including rice substitutes like konjac rice, which contains just 9 calories per 100 grams.
Calorie Counts by Rice Variety
Rice calories vary more than most people expect. For a standard cooked cup, here’s how the most popular varieties compare:
- Long-grain white rice: ~205 calories per cooked cup
- Brown rice: ~194 calories per 3/4 cup cooked (roughly equivalent by dry weight to 1 cup of white)
- Parboiled rice: ~194 calories per cooked cup
- Red rice: ~217 calories per cooked cup
- Short-grain white rice: ~270 calories per cooked cup
The surprise here is that brown rice and parboiled rice actually come in slightly lower than standard white rice when you compare equal dry amounts. Brown rice is denser and absorbs less water during cooking, so a cup of cooked brown rice contains more actual grain than a cup of cooked white rice. When researchers compare equal weights of cooked rice (about 155 grams), brown and parboiled rice both land at 194 calories versus 205 for white.
Why Short-Grain Rice Has More Calories
Grain length makes a meaningful difference. A half cup of cooked long-grain white rice has about 105 calories, while the same amount of short-grain white rice has 135 calories. That’s nearly 30% more. Short-grain varieties (like sushi rice) are stickier because they contain more of a specific type of starch that packs tightly together. This higher starch density translates directly into more calories per bite. If you’re choosing between rice types at the grocery store and calories matter to you, long-grain varieties are the better pick.
Konjac Rice: The Ultra-Low-Calorie Substitute
If your goal is to cut calories dramatically, konjac rice (sometimes called shirataki rice) is in a different league entirely. It contains just 9 calories per 100 grams, compared to roughly 130 calories per 100 grams for cooked white rice. That’s over 90% fewer calories.
Konjac rice is made from the root of the konjac plant, which is almost entirely water and a type of soluble fiber called glucomannan. It doesn’t taste like rice on its own. The texture is slightly rubbery, and it works best in dishes with strong sauces or seasonings that can carry the flavor. Many people mix it 50/50 with regular rice to cut calories without fully giving up the taste and texture they’re used to.
How Cooking and Cooling Changes the Math
You can lower the usable calories in any rice by cooking it, then cooling it in the refrigerator before eating. When cooked rice cools, some of its starch converts into resistant starch, a form your body can’t fully digest. Resistant starch provides about 2.5 calories per gram instead of the usual 4 calories per gram for regular starch. That’s a roughly 40% calorie reduction for every gram of starch that converts.
The total calorie savings for an entire serving are more modest, since only a portion of the starch actually converts. But it adds up if you eat rice regularly. The resistant starch remains even if you reheat the rice afterward, so cooking a batch ahead of time and refrigerating it before reheating is a simple way to shave off some calories without changing what you eat. Parboiled rice already contains more resistant starch than regular white rice due to its processing, which partly explains its lower calorie count.
Black Rice and Red Rice: More Nutrients, Similar Calories
Black rice (sometimes called forbidden rice) and red rice don’t offer calorie savings over white rice. Red rice runs about 217 calories per cooked cup, slightly above white rice. Black rice is comparable, with a quarter cup of dry black rice providing about 160 calories before cooking.
Where these varieties stand out is in their nutrient density. Both contain pigments called anthocyanins, the same compounds that give blueberries and red cabbage their color. They also deliver more fiber and minerals than white rice. If you’re choosing rice purely for the lowest calorie count, these aren’t the answer. But if you’re trying to get more nutrition from each calorie you eat, they’re worth considering.
Practical Ways to Reduce Rice Calories
Your best strategies depend on how much you’re willing to change your routine:
- Easiest swap: Switch from short-grain to long-grain rice. This alone can save 50 or more calories per cup with no change in how you cook or eat.
- Cook and cool: Make rice ahead of time, refrigerate it for at least 12 hours, then reheat. This increases resistant starch and lowers digestible calories.
- Try parboiled rice: It has about 10 fewer calories per cup than regular white rice, plus more resistant starch and a firmer texture that holds up well in meal prep.
- Blend with konjac rice: Mixing half regular rice with half konjac rice can cut the calorie count of your portion nearly in half while keeping a familiar texture.
- Reduce portions with volume: Stirring riced cauliflower into cooked rice is another common strategy for lowering calories per serving without eating a noticeably smaller bowl.
