  1. What are the three steps in a typical photo food-logging process?
    • Scan the barcode, weigh the food, print a label
    • Identify foods, estimate portions, look up nutrients in a database
    • Take a photo, share it, get likes
    • Count chews, time the meal, estimate calories
  2. Which step does the guide call the hardest?
    • Identifying a banana
    • Adding up the totals
    • Portion estimation
    • Choosing the photo angle
  3. Why do home-cooked stir-fries often come out too low in calories?
    • Cooking oil is often invisible in the photo and never logged
    • Vegetables are always overestimated
    • Apps cannot recognize chicken
    • Stir-fries are not in nutrition databases
  4. What does the guide say about a precise-looking total such as 612 calories?
    • It proves the app used a food scale
    • It is always within 5 calories
    • It means the app used the USDA database
    • How confident the app looks tells you nothing about how accurate it is
  5. Why can two plates of the same size look different in a single photo?
    • Cameras change the colors of food
    • A flat image loses depth, so distance from the camera changes apparent size
    • Apps crop every image the same way
    • Plates reflect light differently
  6. Why does converting food volume to weight add error?
    • The same volume of food can weigh different amounts, like packed versus fluffy rice
    • Weight is not used in nutrition databases
    • Apps always round weight to the nearest kilogram
    • Volume cannot be measured at all
  7. What self-test does the guide suggest for checking an app's accuracy?
    • Photograph the same meal with the flash on and off
    • Compare two different apps' totals
    • Log a few meals you have weighed and compare them with the app's estimates
    • Ask the app to rate its own confidence
  8. Who does the guide say should talk to a doctor or dietitian rather than start with a tracking app?
    • Anyone who eats at restaurants
    • People who cook with oil
    • People with a phone that has no depth sensor
    • People with a history of disordered eating
