How to Switch from WeightWatchers to MyFitnessPal (2026 Guide)

Why People Switch from WeightWatchers to MyFitnessPal

The drivers in our reader survey are usually:

• Cost: WW is $20-25/mo depending on plan; MyFitnessPal Premium is $7/mo annual.
• Points fatigue: Users tire of the Points system, particularly after WW has changed it multiple times (Points → SmartPoints → PersonalPoints → current).
• Wanting actual calories: Many users find Points opaque and prefer direct calorie + macro counting.
• Plateau: After initial weight loss, users feel they have outgrown the program structure.
• Lifestyle change: Migrating to a recomp or maintenance phase where Points framing is less useful than macro precision.

This migration is more a category change than a feature swap — you are leaving a behavioral program for a measurement tool.

Before You Migrate: What to Know

WW and MyFitnessPal use different math. WW’s Points system is a weighted formula combining calories, saturated fat, sugar, and protein into a single number. MyFitnessPal uses straight calorie counting with macro tracking on top.

This means historical Points data does not cleanly translate to calorie data. The conversion is approximate — useful for understanding past patterns, not useful as a measurement reference.

If the Points system is what made WW work for you, MyFitnessPal will feel different. The lack of “ZeroPoint” foods (free foods in WW) means everything you eat now has a number on it. Some users find this clarifying; some find it harder.

Step 1: Export Your Data from WW

WW complies with data export requests, but the timeline is the longest in our migration catalog:

1. Open weightwatchers.com on web.
2. My Profile → Account Settings → Data Download.
3. Submit the request.
4. Wait 14-30 days for the email with the download link.
5. Download the ZIP. The relevant files: weigh-in history, food log (with Points), workshop attendance.

Export before cancelling. Some data is harder to access after cancellation.

Step 2: Cancel the WW Subscription

1. Account → Subscription → Cancel.
2. The flow is multi-step with retention offers.
3. Save the cancellation confirmation email.
4. If you are on a Workshop subscription, that has separate cancellation logic.

Step 3: Import to MyFitnessPal

The Points-to-calorie conversion is the bottleneck:

1. Run ww-to-mfp from github.com/calorie-tools/ww-to-mfp on the WW food log CSV. This applies the published Points formula in reverse to estimate calories.
2. Sign in to myfitnesspal.com → Settings → Import.
3. Upload the converted CSV.
4. Review the Pending folder.
5. Decide: import for historical reference, or treat the export as reference-only and start fresh.

Most users find a fresh start cleaner. The Points conversion error (±10-15%) means imported history is approximate; the weight history (which is exact) is the more useful artifact to bring forward.

MyFitnessPal Premium is required for CSV import.

What You’ll Lose

• Points scoring: Converted approximately to estimated calories.
• ZeroPoint foods: The “free foods” framework does not exist in MyFitnessPal.
• Workshop attendance and coach history.
• WW recipes with Points scores.
• Behavioral framing: WW’s program structure does not exist in MyFitnessPal.
• Streaks.

What’s Better in MyFitnessPal

• Cost: $7/month annual vs $20-25/month WW.
• Calorie + macro precision: Actual numbers instead of weighted Points.
• Database breadth: 14M entries.
• Restaurant chain coverage: Best in category.
• Photo AI: Meal Scan on Premium.
• Free tier: Usable.

What’s Worse in MyFitnessPal

• No behavioral program: WW provides structure that MyFitnessPal does not.
• No coach access: If WW Workshops were part of why you joined, this gap is real.
• Mid-tier accuracy: ±18% MAPE per the DAI Six-App Validation Study. WW was not validated, but the program quality is more about behavioral support than measurement.
• Ad load: MyFitnessPal serves ads aggressively on free.

First-Week Setup in MyFitnessPal

1. Set a daily calorie goal. This is the central change from Points — you are now hitting a number, not a Points budget.
2. Set macro percentages under Goals. WW’s PersonalPoints algorithm baked macro guidance into the Points system; MyFitnessPal makes you set this explicitly.
3. Pin your most-used foods.
4. Decide on Premium ($79.99/yr). Most ex-WW users find Premium worth it because the cost is still less than half of WW.
5. Establish a logging cadence that does not depend on coach check-ins.

Bottom Line

WW-to-MyFitnessPal is a category change more than a feature change. You are saving roughly $13-18/month and shifting from a behavioral program to a measurement tool. If the program structure was what worked for you, this migration will feel less supportive. If you have already extracted the behavioral value and want to track calories cheaply, MyFitnessPal is a reasonable destination.

Users who specifically want measurement-grade accuracy after WW would do better looking at Cronometer (±5.2%, $54.95/yr Gold, free tier excellent) instead of MyFitnessPal.

Step 1: Export from WeightWatchers

1. Open WeightWatchers (WW) on web at weightwatchers.com — mobile export is limited.
2. Sign in and go to My Profile → Account Settings → Data Download.
3. Submit a data export request. WW complies with GDPR/CCPA-style requests.
4. Wait for the email confirmation. Export typically arrives within 14-30 days.
5. The export ZIP includes weigh-in history, food log (with Points), workshop attendance, and account metadata.
6. Important: cancel the subscription separately under Account → Subscription. Cancellation is multi-step.

Step 2: Import to MyFitnessPal

1. MyFitnessPal does not have a guided WW importer.
2. WW's food log uses Points, not calories — these need conversion before import.
3. Use the community converter 'ww-to-mfp' at github.com/calorie-tools/ww-to-mfp which converts Points entries to estimated calorie values using WW's published formulas.
4. The converter is approximate — Points-to-calorie conversion produces ±10-15% error on the converted log.
5. Sign in to myfitnesspal.com → Settings → Import.
6. Upload the converted CSV.
7. Review the Pending folder for unmatched entries.
8. Mostly, treat the imported history as reference and start fresh logging in MyFitnessPal.

What you'll lose in migration

• Points scoring does not transfer — converted to estimated calories with meaningful approximation error.
• ZeroPoint food categorization (free foods in WW) does not exist in MyFitnessPal — those foods become standard calorie entries.
• Workshop attendance and coach interaction history is WW-specific.
• WW recipes do not transfer with their Points scores.
• Any active WW Workshop or coach relationship ends with the subscription.
• Streaks reset.
