Logging foods will not be 100% accurate, the actual eaten portion can contain more or less nutritients / calories.. when estimating food intake, could log more or less than actually eaten. Depending on the type of foods, the body can require more or less energy for digesting a certain food. Some foods can also take up to 36+ hours before fully digested..
Foods prepackaged can also contain more or less calories than mentioned on the package.
When desired, aim to eat nutrition rich foods overall when hungry as minimal as processed, those foods contain lots of nutritients the body requires and nature intended us to have, leaving satisfied for longer, on lower calories overall.. having a little treat once a while..
(Fruits, vegetables, eggs, meats, fish,..), foods without labels are the best for the body.. (when counting calories, it's easier to scan a label of some junk food, though the fruits,.. being a better choice for the body when wanting to, and leaves satisfied for longer). Not restricting any foods, having everything with care.. (eating until comfortably satisfied, not stuffed).
Foods like cookies, containing sugars,.. overall higher in calories.. leave the body possibly being hungry, and wanting more from (cause of the added sugars).. not necessary out of being hungry.
