Custom Food Entry

Also known as: custom food, user-created entry

A food entry you create yourself — typically from a nutrition label — when the database doesn't have a reliable match for something you eat often.

Key takeaways

  • Custom food entries fill gaps in the database for foods you actually eat but can't find a verified match for.
  • Created once from the label, then reused every time you log that food — no more re-searching.
  • Private (only you see them) by default in most apps; some let you share to the community.
  • Worth building a small library of your top 10–20 personal staples; saves huge adherence friction.

A custom food entry is a food you add to your tracking app yourself — typically by typing in the nutrition info from the package label — when the existing database doesn't have a match you trust. Most apps let you build a private library of custom foods that only appear in your searches.

When you need one

Four common scenarios:

  • Store-brand packaged food. Store brands often aren't in the manufacturer database.
  • Regional or international product. A brand popular in one country but not the app's primary market.
  • Home-made staple. Your usual breakfast smoothie, protein shake mix, or granola batch.
  • Restaurant item not in chain database. A local cafe's sandwich you order weekly.

How to create one

The flow is similar across apps:

  1. Tap "Add food" or "Create custom food."
  2. Enter the food name.
  3. Enter the serving size (grams is best; use whatever the label says).
  4. Enter calories, protein, carbs, fat, fiber — straight from the label.
  5. Optional: enter brand, micronutrients, or a photo.
  6. Save.

Takes 60 seconds. You only do it once per food.

Where apps differ

  • Cronometer: custom entries can include detailed micronutrient fields, which pays off if you track vitamins and minerals.
  • MacroFactor: supports custom foods with gram-first entry.
  • MyFitnessPal: custom foods are private by default, with a toggle to share with the community.
  • Lose It!: straightforward custom-entry form.
  • Yazio: simple custom entry; fewer optional fields.

Custom foods and barcode scanning

Some apps can attach your custom entry to a scanned UPC — so next time you scan the bag, your custom entry shows up instead of a "not found" message. Others don't link the two, meaning you'll have to search for your custom entry manually. Check your app's behavior on the first repeat scan.

Keeping the library clean

After a few months, your custom list can get cluttered with items you tried once. Every quarter or so, prune the entries you haven't used. You can also prefix names ("[HOME] Breakfast oats") to separate your daily staples from one-off imports.

Why it's worth the setup

A personal library of 10–20 custom foods you eat weekly changes the logging experience. Searches get faster. Results are accurate. You stop picking between three user-submitted guesses. That small friction reduction is often the difference between sustainable tracking and giving up in month two.
