At this time, there is not a data reset feature available for the program. We will definitely consider making this option available in a future update.
Our recommended option is to reset your starting date, weight and goals. As an alternative, you may delete your account and start over, but doing so will delete all of your information, and will require you to chose a new username.
You may access either option on our website at www.myfitnesspal.com. Mobile app users should log in using the same email address and password they use in the app.
Once you've logged in, If you would like to delete your account, click "My Home" then "Settings" then "Delete Account." Please note, if you are a Premium member, you will need to wait until your subscription ends before deleting your account, as Premium subscriptions are non transferable from one account to another. You may also delete your account in the apps by going to the "Menu" (or "More") page > "Help" > then "Delete Account."
If you would prefer to update your profile on our website, click "My Home" then "Settings" then "Update diet/fitness profile" to set a new starting weight and goal weight.. Make sure you hit the green "Update Profile" button at the bottom of the page. In our apps, select the "Menu" (or "More") button > "Goals" > then tap the information there you wish to update.
We then recommend updating your current starting weight and date so that your weight loss ticker will reflect your fresh start.
