Is this calorie calculation correct?

I know the calculation for the rice is way off (unless it's prepared some special, calorie dense way).

I'm guessing you are talking about a 16 ounce package of uncooked rice, which would be in that range, maybe a couple hundred more. Cooked rice on the other hand has about 1.3 calories per gram, or 206 for 158 grams which is pretty close to a cup, according to rice packages.

white rice (16 oz)
- 1350 calories
- 296 carbs
- 26 protein


So is the TOTAL correct? What i mean is, is white rice really 1350 calories (16 oz), etc.. is everything seems to be normal and not over calculated?

The quick answer is YES, the numbers you calculated are in the ballpark.

Here is the detailed explanation.

Note that a lot of packaged rice in the US is partially boiled (parboiled) and the little bit of water introduced in that process reduces the macros per 100g slightly. If you have the Nutrition Facts from the package, you can just substitute those numbers into the calculations below. I got the macros from the MFP food database, which mirrors the USDA numbers.

1-8oz glass of uncooked (raw) rice = 227g uncooked (raw) rice

2-8oz glasses of raw rice x 227g = 454g raw rice

from the MFP database:
Rice - white, long-grain, regular, raw, enriched = 365 cal/80g carbs/1g fat/7g protein per 100g

So,
454g rice, raw x 365 cal/100g = 1657 cal
454g rice, raw x 80g carbs/100g = 363.2g carbs
454g rice, raw x 1g fat/100g = 4.54g fat
454g rice, raw x 7g protein/100g = 31.8g protein

Hope this helps.
