A cup of cooked long-grain white rice contains roughly 200 calories, with the vast majority coming from carbohydrates. That makes it one of the most calorie-dense staple grains per serving, though the exact number shifts depending on the variety you choose and how you prepare it.
Calories by Rice Variety
Not all white rice is created equal. The variety you pull off the shelf changes the calorie count enough to matter if you’re tracking closely. Basmati rice runs about 210 calories per cooked cup, while jasmine rice comes in slightly lower. Short-grain varieties like sushi rice tend to be stickier and more compact, which means a “cup” of cooked short-grain rice can pack more grains and slightly more calories than the same cup of a fluffier long-grain variety.
The difference between varieties rarely exceeds 20 to 30 calories per cup, so for most people, it’s not worth agonizing over. What matters more is how much you serve yourself, since rice is easy to over-portion.
What Else Is in That Cup
White rice is almost pure starch. A cup of cooked long-grain white rice delivers about 44 grams of carbohydrates, around 4 grams of protein, and less than 1 gram of fat. Fiber is minimal at roughly 1.4 grams per cup, because the milling process strips away the bran layer where most of the fiber lives.
Most white rice sold in the U.S. is enriched, meaning manufacturers add back some of the B vitamins and iron lost during milling. You’ll get a meaningful amount of folate and thiamine from enriched white rice, though it still falls short of brown rice in terms of overall nutrient density. If rice is a staple in your diet, the enrichment matters: it’s the reason white rice consumption doesn’t commonly lead to nutrient deficiencies in countries that mandate fortification.
How Cooking Changes the Calorie Math
A lesser-known trick can nudge the calorie count down. Researchers found that cooking rice with a small amount of coconut oil, then refrigerating it for 12 hours before eating, reduced digestible calories by 10 to 15 percent. The cooling process converts some of the rice’s starch into resistant starch, a form your body can’t fully break down and absorb. Reheating the rice afterward doesn’t reverse this effect.
In practical terms, that could drop a 200-calorie cup down to around 170 to 180 calories. The researchers projected that using rice varieties naturally high in a specific type of starch (called amylose) could push the reduction even further, potentially to 50 or 60 percent. For now, the 10 to 15 percent drop is what’s been confirmed in lab testing, and it’s an easy win if you meal-prep rice ahead of time anyway.
How Rice Compares for Fullness
Calories only tell part of the story. How full a food keeps you determines whether those 200 calories tide you over until dinner or leave you snacking an hour later. In a well-known satiety study published in the European Journal of Clinical Nutrition, researchers ranked common foods by how satisfying they were per calorie, using white bread as the baseline at 100 percent.
White rice scored 138 percent, meaning it kept people noticeably fuller than white bread, French fries (116 percent), or white pasta (119 percent). Brown rice scored slightly lower at 132 percent. Boiled potatoes dominated the chart at 323 percent, more than double the satiety of rice for similar calories. So if you’re trying to feel full on fewer calories, potatoes are the clear winner. But rice holds its own against most other starchy sides.
Portion Sizes That Match Your Goals
Rice expands dramatically when cooked, roughly tripling in volume. A quarter cup of dry rice yields about three-quarters of a cup cooked, which comes to roughly 150 calories. That’s a reasonable side portion for most adults. Restaurant servings are typically a full cup or more, which can push a single side dish past 300 calories before you add anything on top.
UK government guidelines for school meals suggest 55 to 65 grams of dry rice per serving for teenagers, which works out to about 190 to 225 calories of cooked rice. That’s a useful benchmark for adult portions too, since it lands in the range most dietitians consider moderate.
Blood Sugar Response
White rice has a glycemic index ranging from 64 to 93 on a scale where pure glucose is 100. That’s a wide range, and the variety you eat explains most of the difference. Rice varieties high in amylose (a type of starch that resists digestion) produce a significantly lower blood sugar spike than sticky or “waxy” varieties, which are digested quickly and send glucose into your bloodstream faster.
Basmati rice tends to fall on the lower end of the glycemic index spectrum, while sticky rice sits near the top. Refrigerating cooked rice before eating it also lowers the glycemic response across all varieties, with the stickiest types seeing the biggest drop. If you’re managing blood sugar, choosing a long-grain basmati and cooling it before eating gives you the gentlest glycemic profile white rice can offer.
