Plate Diameter Portion Illusion
Plate diameter portion illusion changes how much food looks on camera—standard plates or noted dish size improve photo portion guesses.
Plate diameter portion illusion makes the same grams look like a small or large serving depending on dish size—dinner plates versus salad plates change perceived adequacy and photo-model volume guesses. Large rims also shrink the edible area models measure.
Note your usual plate in settings or include a standard bowl in meal prep photos.
Common questions
-
Do smaller plates help logging accuracy?
They reduce illusion for eaters but can confuse models trained on average dinnerware—consistency matters more than size. Pick one default plate for photo meals you log often.
