Reading Food Labels & Logging by Barcode

Packaged foods hide a lot. Two minutes of label literacy saves your deficit.

Packaged and restaurant foods are where hidden calories live. Learning to read a label — and logging accurately — is a skill that pays off for life.

What to check first

• •Serving size — the numbers are per serving, not per pack
• •Calories per serving (and how many servings you'll really eat)
• •Protein — your most important macro
• •Added sugar and oils hiding in the ingredient list

Watch the serving-size trick

A snack pack may list 90 calories per serving but contain 2.5 servings. Always multiply by what you actually eat. Drinks and condiments are notorious for this.

PRIME lets you scan a barcode to pull nutrition straight from the Open Food Facts database, or snap a photo of a meal for an AI estimate — so logging packaged and home food is fast and honest.
