How to Switch from Lose It! to MyFitnessPal (2026 Guide)

Why People Switch from Lose It! to MyFitnessPal

The driver is almost always database breadth. Lose It!‘s 7M entries are excellent for North American users; less good for international users. The most common pattern in our reader survey:

• User starts Lose It! for the cleaner UX.
• Travels internationally or moves; finds barcode and chain coverage thin.
• Searches for specific items more often than ideal; result quality drops.
• Migrates to MyFitnessPal for the 14M-entry catalog.

Other drivers:

• Wanting access to MyFitnessPal’s larger community/feed.
• Preferring MyFitnessPal Meal Scan over Lose It!‘s Snap It (both photo AI features are mid-pack but some users prefer one over the other).
• Returning from a hiatus and finding old MyFitnessPal credentials still active.

This migration is unusual: you are paying more ($79.99 vs $39.99 Premium) for a slightly worse-accuracy app with broader coverage. Make sure the trade-off solves a real problem before making it.

Before You Migrate: What to Know

Both Lose It! and MyFitnessPal are similar-category apps with similar database structures (largely user-submitted, with verified layers). The differences are at the margins:

• Database breadth: MyFitnessPal wins.
• UX polish: Lose It! wins.
• Premium price: Lose It! wins ($39.99 vs $79.99).
• Accuracy: Lose It! wins marginally (±12.4% vs ±18% MAPE per the DAI Six-App Validation Study).
• Restaurant chain coverage: MyFitnessPal wins.
• International coverage: MyFitnessPal wins.
• Community features: MyFitnessPal wins.
• Photo AI: Roughly tied.
• Free tier value: Roughly tied.

If the only reason to migrate is to access a few specific restaurant chains MyFitnessPal has and Lose It! does not, consider keeping Lose It! and using a free MyFitnessPal account selectively for those entries.

Step 1: Export Your Data from Lose It!

Lose It!‘s export is web-only and Premium-required for full history. The free tier exports the last 30 days only.

1. Sign in to loseit.com on web.
2. Settings → Export Data.
3. Date range: All Time.
4. Format: CSV.
5. Submit — CSV downloads within about a minute (no email wait).

If you are on free, upgrade to Premium for one month ($39.99 prorated, or just take a one-month subscription) to access full export.

Step 2: Import to MyFitnessPal

MyFitnessPal does not ship a guided Lose It! importer. Use the generic CSV path with the community converter:

1. Run loseit-to-mfp from github.com/calorie-tools/loseit-to-mfp on your Lose It! CSV.
2. Sign in to myfitnesspal.com.
3. Settings → Import.
4. Upload the converted CSV.
5. Review the Pending folder for unmatched entries.
6. Resolve each: map to MyFitnessPal database, create custom food, or skip.

MyFitnessPal Premium is required for CSV import. If you do not have it yet, upgrade for one billing cycle for the migration.

What You’ll Lose

• Lose It!‘s cleaner UX.
• Snap It photo logs: Only the resulting calorie entries transfer; the photo logs themselves do not.
• Recipes: Rebuild in MyFitnessPal.
• Custom foods: Adjust serving sizes for MyFitnessPal’s format.
• Community features specific to Lose It!: The community in MyFitnessPal is different.
• Streaks.
• Half your annual Premium cost: $79.99 vs $39.99.

What’s Better in MyFitnessPal

• Database breadth: 14M entries.
• International coverage: Stronger barcode and chain coverage outside North America.
• Community feed: More active.
• Integrations: Marginally broader.

What’s Worse in MyFitnessPal

• UX: More cluttered, more ads on free, more upsell pressure.
• Premium price: Double.
• Accuracy: Marginally worse.
• Free tier: More features paywalled (recipe URL import, verified-entry filter, micros, data export).

First-Week Setup in MyFitnessPal

1. Set up goals.
2. Resolve the Pending folder for the top 30 most-frequent imports.
3. Set the verified-entry filter to default (Premium feature).
4. Pin your most-used foods.
5. Connect integrations under Apps.
6. Decide whether the broader database actually solves your problem. If it does not, going back to Lose It! within the first 30 days is a reasonable choice.

Bottom Line

Lose It!-to-MyFitnessPal is an unusual migration because Lose It! is in many ways the better-designed app at half the Premium price. The reason to switch is database breadth and restaurant coverage. If that is your specific need, MyFitnessPal solves it. If your need is accuracy, look at Cronometer (±5.2%) or PlateLens (±1.1%) instead — both materially tighter than either of these mid-tier options.

Step 1: Export from Lose It!

1. Open Lose It! on web at loseit.com — mobile app does not allow full export.
2. Sign in and go to Settings → Export Data.
3. Choose date range — 'All Time' for full history.
4. Select export format: CSV.
5. Submit. The CSV downloads directly within a minute (no email wait).
6. Premium is required for full export; free tier offers a limited 30-day export.

Step 2: Import to MyFitnessPal

1. MyFitnessPal does not have a guided Lose It! importer in 2026.
2. Use the generic MyFitnessPal CSV importer at myfitnesspal.com → Settings → Import.
3. The community converter 'loseit-to-mfp' at github.com/calorie-tools/loseit-to-mfp reformats Lose It! CSVs to MyFitnessPal-expected column headers.
4. Upload the converted CSV to MyFitnessPal web.
5. Review the Pending folder for unmatched entries.
6. Map each pending entry to a MyFitnessPal database hit, custom food, or skip.
7. MyFitnessPal Premium is required for CSV import.

What you'll lose in migration

• Lose It! Snap It photo logs do not transfer — only resulting calorie/macro entries do.
• Custom foods will need adjustment for MyFitnessPal's serving size formats.
• Recipes will need to be rebuilt in MyFitnessPal's recipe editor.
• Lose It!'s community features and any saved meal plans do not transfer.
• Streaks reset on the new app.
• Some Lose It! database entries do not have a clean MyFitnessPal equivalent and will land in Pending for manual mapping.
