An equation is a starting estimate
The maintenance calculator combines an equation for resting expenditure with an activity assumption. Neither is a direct measurement of your energy use. It does not set an automatic weight-loss target.
Match the record to the food
Dry rice and cooked rice describe different water contents. The food calculator identifies preparation states and lets you enter a package label. Do not substitute one state for another simply because the food name matches.
Use a batch total when cooking changes weight
For a mixed dish, add the relevant ingredients and divide by the measured finished batch or number of portions. Water loss changes final weight; it does not turn one hundred grams of a cooked dish into the same amount of every raw ingredient.
