Water absorption
Cooked rice weighs more because it absorbs water, which adds weight but not calories.
Rice weight tracking
Rice gets heavier when cooked because it absorbs water, so dry and cooked weights need matching nutrition entries.
Quick answer
Track rice by using dry weight with a dry rice entry, or cooked weight with a cooked rice entry. Do not weigh boiled rice and log it as dry rice. Water changes weight, not the original calories from the dry rice.
Decision criteria
Food tracking works best when the major calorie and macro drivers are separated instead of collapsed into one vague entry.
Cooked rice weighs more because it absorbs water, which adds weight but not calories.
Dry weights need dry entries. Cooked weights need cooked entries.
Meal prep works best when total dry rice calories are divided across cooked servings.
Dry rice absorbs water during cooking. The pot gets heavier, but the added weight is mostly water, not new calories.
That is why cooked rice has fewer calories per gram than dry rice. It is diluted by water.
The big mistake is weighing cooked rice and logging that number as dry rice. That can overcount dramatically.
Either weigh the dry rice before cooking, or weigh your cooked serving and use a cooked rice entry.
Create a recipe from the dry rice amount, then divide the final cooked batch into servings. Or save a cooked rice entry you trust and weigh cooked portions.
Use one method consistently across meal prep.
Either works if you use the matching entry. Dry weight with dry rice, cooked weight with cooked rice.
Because it absorbs water, increasing weight without adding calories.
No. That will usually overcount because cooked rice includes water weight.
