How to Switch from WeightWatchers to MyFitnessPal (2026 Guide)

Reasons for Switching from WeightWatchers to MyFitnessPal

The main reasons highlighted in our reader survey include:

This transition is more of a category shift rather than just a feature exchange, as you are moving from a behavioral program to a measurement tool.

Important Information Before You Migrate

WW and MyFitnessPal utilize different calculations. WW’s Points system is based on a weighted formula that combines calories, saturated fat, sugar, and protein into a single value. In contrast, MyFitnessPal relies on straightforward calorie counting along with macro tracking.

This implies that historical Points data does not directly convert to calorie data. The conversion is only an estimate, suitable for grasping past trends, but not effective as a precise measurement reference.

If the Points system was the reason WW was effective for you, MyFitnessPal will present a different experience. The absence of “ZeroPoint” foods (the free foods in WW) indicates that everything consumed will now have a numeric value. Some users appreciate this clarity, while others may find it challenging.

Step 1: Export Your Data from WW

WW accommodates data export requests, but the process takes the longest among our migration guides:

  1. Visit weightwatchers.com on a web browser.
  2. My Profile → Account Settings → Data Download.
  3. Submit your request.
  4. Wait for 14-30 days to receive an email containing the download link.
  5. Download the ZIP file, which includes weigh-in history, food log (with Points), and workshop attendance records.

Make sure to export your data before cancelling. Some information may be more challenging to access post-cancellation.

Step 2: Cancel the WW Subscription

  1. Account → Subscription → Cancel.
  2. The cancellation process involves multiple steps with retention offers.
  3. Keep the email confirmation of your cancellation.
  4. If you have a Workshop subscription, note that it has a different cancellation process.

Step 3: Import to MyFitnessPal

The conversion from Points to calories is the critical step:

  1. Use ww-to-mfp from github.com/calorie-tools/ww-to-mfp on the WW food log CSV. This tool applies the published Points formula in reverse to estimate calorie content.
  2. Log in to myfitnesspal.com → Settings → Import.
  3. Upload the converted CSV file.
  4. Check the Pending folder for any entries that need review.
  5. Decide whether to import for historical context or treat the export as a reference and start anew.

Many users find starting fresh to be a cleaner approach. The Points conversion error (±10-15%) indicates that imported history is approximate; the weight history (which is accurate) is the more valuable data to transfer.

CSV import requires a MyFitnessPal Premium subscription.

What You Will Lose

Advantages of MyFitnessPal

Disadvantages of MyFitnessPal

Setting Up Your First Week in MyFitnessPal

  1. Set a daily calorie target. This represents a fundamental shift from Points, as you will now be aiming for a specific number rather than a Points budget.
  2. Define macro percentages under Goals. WW’s PersonalPoints algorithm integrated macro guidance into the Points system, while MyFitnessPal requires you to set this separately.
  3. Pin your frequently used foods.
  4. Consider Premium ($79.99/year). Most former WW users find Premium to be worthwhile since the cost is still less than half of WW.
  5. Establish a logging routine that does not rely on coach check-ins.

Conclusion

For users specifically seeking measurement-grade accuracy post-WW, it would be advisable to consider Cronometer (±5.2%, $54.95/year Gold, excellent free tier) instead of MyFitnessPal.

Step 1: Export from WeightWatchers

  1. Access WeightWatchers (WW) online at weightwatchers.com; mobile export options are limited.
  2. Log in and navigate to My Profile → Account Settings → Data Download.
  3. Request data export. WW adheres to GDPR/CCPA-style regulations.
  4. Await the email confirmation; the export typically arrives within 14-30 days.
  5. The exported ZIP file contains weigh-in history, food log (with Points), workshop attendance, and account metadata.
  6. It's crucial to cancel your subscription separately via Account → Subscription, as cancellation follows a multi-step process.

Step 2: Import to MyFitnessPal

  1. MyFitnessPal lacks a guided WW importer.
  2. WW's food log is based on Points rather than calories, necessitating conversion prior to import.
  3. Utilize the community converter 'ww-to-mfp' at github.com/calorie-tools/ww-to-mfp, which translates Points entries into estimated calorie values using WW's published formulas.
  4. The converter provides an approximation, with Points-to-calorie conversion resulting in ±10-15% error in the converted log.
  5. Log in to myfitnesspal.com → Settings → Import.
  6. Upload the converted CSV file.
  7. Review the Pending folder for any unmatched entries.
  8. Generally, treat the imported history as a reference and begin fresh logging in MyFitnessPal.

What you'll lose in migration

  • Points scoring does not carry over; it will be converted into estimated calories with significant approximation error.
  • ZeroPoint food categorization (free foods in WW) does not exist in MyFitnessPal, turning those foods into standard calorie entries.
  • Workshop attendance and coach interaction history are specific to WW.
  • WW recipes do not transfer with their Points values.
  • Any ongoing WW Workshop or coaching relationship terminates with the subscription.
  • Streaks will reset.

FAQs

Why switch from WeightWatchers to MyFitnessPal?

Common reasons include cost (WW is about $20-25/month versus $7/month for MyFitnessPal Premium), a preference for actual calorie counting over Points, and dissatisfaction with the evolving Points system throughout WW versions.

Can Points be converted to calories accurately?

Not precisely. The established Points formulas (which have evolved over time, including Points, SmartPoints, PersonalPoints, and the current system) factor in calories, saturated fat, sugar, and protein. The converter applies the formula in reverse to estimate calories, with an error margin of ±10-15%, which is not suitable for precise measurement but can be helpful for historical reference.

Should I import the historical data or start from scratch?

Most users find beginning anew to be more effective. Import the weight history (which is accurate) and start logging foods in MyFitnessPal from day one. The historical food log serves better as a reference than as live data.

What is the process to cancel WW?

Navigate to Account → Subscription → Cancel. This process includes retention offers and may involve multiple steps. Retain the cancellation confirmation. If you have a Workshop subscription, note that it has a different cancellation procedure.

Is MyFitnessPal more accurate than WW?

This is a different inquiry; WW Points do not directly correlate with calorie measurement. MyFitnessPal achieved a ±18% MAPE in the DAI Six-App Validation Study (March 2026). WW was not included in the study as it does not primarily function as a calorie tracker.
