What measurements show
In three US cities, frequently ordered meals from smaller restaurants had 1,205 kcal on average, with a wide spread of plus or minus 465 kcal.[1] The measurements come from the US and cannot simply be applied to other countries.
Printed values are only a guide too. Across 269 foods from 42 restaurants they were accurate on average, but 19% had at least 100 kcal more than stated.[2]
The portion counts too
In a trial with 51 people, participants ate 30% more energy from the largest portion than from the smallest.[3] This was true no matter who filled the plate.
What helps in everyday life
- Enter a range instead of looking for an exact number. That is what ranges in the app are for.
- Share a large portion or take the rest with you if you are already full.
- See the evening as one day among many. Single days say little.
Why ranges are more honest here is explained in Why the app shows ranges.
The app does not replace medical advice.
