The lowest calorie traditional rice is parboiled (converted) rice at 194 calories per cooked cup. If you’re open to substitutes, cauliflower rice drops that number to just 28 calories per cup, and konjac-based shirataki rice is essentially calorie-free. Which option makes sense depends on whether you want actual rice or simply something that looks and functions like rice on your plate.
Traditional Rice, Ranked by Calories
All true rice varieties land in a surprisingly narrow range, roughly 194 to 215 calories per cup cooked. The differences are real but modest. Here’s how they stack up:
- Parboiled (converted) rice: 194 calories per cooked cup, with 1.4 grams of fiber. Parboiled rice is steamed in the husk before milling, which changes its starch structure and slightly lowers its calorie density compared to regular white rice.
- White rice (long-grain): about 205 calories per cooked cup. This is the baseline most people are familiar with.
- Brown rice: 215 calories per cooked cup, the highest of the common varieties. It does deliver 3.5 grams of fiber, more than double what parboiled rice offers, so the extra calories come with extra nutrition.
Wild rice is often grouped with these options, but it’s technically a semiaquatic grass rather than true rice. Its calorie count is comparable to parboiled rice, and it has a chewier texture and nuttier flavor that won’t work in every dish. Jasmine and basmati rice fall close to regular white rice in calories, typically in the 200 to 210 range per cooked cup depending on brand and preparation.
The takeaway: if you’re sticking with real rice, parboiled is your best bet for cutting calories, but you’re only saving about 10 to 20 calories per cup compared to white rice. That’s not going to transform a meal. The bigger calorie savings come from the alternatives below.
Cauliflower Rice: The Biggest Calorie Drop
Cauliflower rice contains 28 calories per cup, according to the Medical University of South Carolina. That’s roughly 88% fewer calories than the same volume of white rice. It also has just 6 grams of carbohydrates compared to over 53 grams in a cup of white rice.
The tradeoff is texture and taste. Cauliflower rice doesn’t absorb sauces the same way, has a slightly grainy bite, and carries a mild vegetable flavor that can come through in dishes with lighter seasoning. It works best in stir-fries, burrito bowls, and heavily seasoned meals where rice is more of a vehicle than a feature. You can buy it frozen in most grocery stores or make it at home by pulsing cauliflower florets in a food processor.
Broccoli rice is a similar option with a comparable calorie count, though it has a stronger flavor that’s harder to mask. For pure calorie reduction with the least noticeable taste difference, cauliflower wins.
Shirataki (Konjac) Rice: Nearly Zero Calories
Shirataki rice, made from konjac root, is the lowest calorie rice substitute you can buy. A full 200-gram packet (drained) contains roughly 10 calories and just 3 grams of net carbohydrates. Per ounce, it has about 1 calorie. The bulk of the product is water and a soluble fiber called glucomannan, which is what gives it structure.
The experience of eating shirataki rice is different from regular rice. It has a slippery, slightly rubbery texture and virtually no flavor on its own. Most brands recommend rinsing it thoroughly and dry-frying it in a pan for a few minutes before adding it to a dish, which helps remove the mild packaging odor and improves the texture. It performs best in dishes with bold sauces or strong seasonings where the rice doesn’t need to contribute flavor.
You’ll find shirataki rice in the refrigerated section of many grocery stores, often near tofu or in the Asian foods aisle. It’s shelf-stable in some brands and sold in pouches.
Legume-Based Rice Alternatives
Products like Banza and RightRice are made from chickpeas, lentils, or other legumes shaped into rice-like grains. They take a different approach than cauliflower or konjac rice. Rather than slashing calories dramatically, they reduce carbohydrates by about 10 grams per serving compared to white rice while delivering significantly more protein and more than five times the fiber. Banza has a slight edge over RightRice on both calories and protein.
These products are designed for people who want rice that still feels like a grain, holds up in pilafs or grain bowls, and adds more nutritional value per bite. The calorie savings are moderate rather than dramatic, but the higher protein and fiber content can help you feel full longer, which may matter more for overall intake than the per-serving calorie number.
How Cooking Affects Calorie Density
One often overlooked factor is that rice roughly triples in volume when cooked. One cup of dry rice yields about three cups cooked. This means the calorie density of your bowl depends heavily on how much water the rice absorbs. Rice varieties that absorb more water (like parboiled or long-grain white) end up slightly less calorie-dense per cup because you’re eating more water by volume.
This also means that letting rice cool after cooking can change its nutritional impact. When cooked rice cools, some of its starch converts into a form your body can’t fully digest, called resistant starch. Reheating the rice doesn’t reverse this process entirely. The practical calorie reduction from this effect is modest, but it’s a free bonus if you’re already meal-prepping rice in advance.
Choosing the Right Option
Your best choice depends on how much of a calorie cut you’re after and how much you care about the eating experience. If you want real rice with a small edge, parboiled rice at 194 calories per cup is the move. If you want to cut calories dramatically and don’t mind a different texture, cauliflower rice at 28 calories per cup is the most practical swap for everyday cooking. If you’re counting every calorie or following a very low-carb diet, shirataki rice is as close to zero as you’ll get.
Mixing works well too. A half-and-half blend of cauliflower rice and white rice gives you a noticeable calorie reduction, around 115 to 120 calories per cup, while keeping a more familiar texture than going fully cauliflower. It’s a middle ground that many people find easier to stick with long-term.
