MyNetDiary and Fitbit – integrate your diet and exercise

MyNetDiary online and mobile diet program helps you lose weight by tracking your food calories with the best nutrition database in the world. MyNetDiary can also keep track and estimate your activity calories based on activity type and duration.

Fitbit tracker uses an accelerometer and other sensors to estimate your daily calories burn, while Fitbit weight scale can automate your weight tracking.

By linking MyNetDiary with Fitbit you get the best of both worlds:

  1. MyNetDiary shows the activity calories, daily steps, and weight measured by Fitbit.
  2. Fitbit shows your food calories and nutrients tracked by MyNetDiary.

Using Fitbit with MyNetDiary helps to calculate daily calorie balance more accurately, see the actual balance of the calories you burn and eat during the day, and ultimately - helps you lose weight faster and smarter!

We highly recommend using Fitbit for activity and weight tracking, while you use MyNetDiary to improve your diet and lose weight.

How does linking work?

Fitbit trackers calculate your activity calories, daily steps, weigh ins, and more, and sync them to the Fitbit website. MyNetDiary keeps track of your foods logged online or via mobile apps. By creating a link, you allow MyNetDiary to talk to Fitbit website and exchange the following data:

  • From Fitbit to MyNetDiary
    • Exercise burned calories (Flex™, One™, Zip™, Charge, Charge HR, Surge)
    • Daily steps (Flex™, One™, Zip™, Charge, Charge HR, Surge)
    • Hours of sleep (Flex™, One™, Charge, Charge HR, Surge)
    • Body weight and body fat percentage (Aria™ WiFi Smart Scale)
    • Body measurements (neck, bicep, chest, waist, hips, thighs, calf)
  • From MyNetDiary to Fitbit
    • Daily foods - including food name, calories, fat, fiber, carbs, sodium and protein content.

Your data is transferred one-way after linking:

  • Fitbit activities, steps, and weigh-ins (if available) are transferred to MyNetDiary
  • MyNetDiary foods entries are transferred to Fitbit.

First of all, make sure you Sign Up for MyNetDiary Maximum or Upgrade to MyNetDiary Maximum. Fitbit linking and many other premium MyNetDiary features are available with MyNetDiary Maximum.

Exchange details

What happens after I link?

After you link to Fitbit, MyNetDiary performs automatic data exchange within several minutes after you enter foods in MyNetDiary, one exchange per hour. If you don't log foods for some day, MyNetDiary will download your Fitbit data during the night. In the case you do not log foods in MyNetDiary for 10 contiguous days, MyNetDiary stops exchanging your data with Fitbit. When you resume logging foods, MyNetDiary resumes Fitbit data exchanges.

If you want to expedite exchange of today's data, go to Account/Fitbit Settings page and click "Verify link" button.

MyNetDiary exchanges last 5 days of data after the link is established or restored.

Fitbit exercise vs. Fitbit calories

Fitbit download creates "Fitbit exercise" entry at MyNetDiary Exercise, which is different from the Daily Total Calories you see on Activities tab at Fitbit web site. MyNetDary exercise includes only the calories burned in addition to normal lifestyle determined by your personal activity level. This is why MyNetDiary subtracts Personalized DRI calories from the downloaded total calories:

Fitbit exercise = Fitbit Daily Total Calories Burned − MyNetDiary Personalized DRI

If Fitbit total calories are less than Personalized DRI, Fitbit exercise is set to zero because negative exercise cannot be used by MyNetDiary planning and analysis features.

Make sure you have chosen the same timezone in MyNetDiary and Fitbit, also make sure your body weight, gender and date of birth settings are the same in both systems.

We recommend setting MyNetDiary Activity Level to Sedentary, since only the calories above the Sedentary level are tracked by "Fitbit exercise" daily entry.

Fitbit body measurements

In addition to exercise calories, Fitbit tracker counts daily steps and may determine hours of sleep. Fitbit Aria scale measures body weight and body fat percentage. You may also enter body measurements like calf, chest, waist, neck, thigh, bicep, hip on the Fitbit website.

MyNetDiary downloads all these measurements from Fitbit. To see the downloaded measurements in MyNetDiary, go to MyNetDiary Daily Details page and click “Select Measurements to Track” link.

Catching up on last several days

In the case you would like to repeat Fitbit download for the last 5 days, please, unlink Fitbit and link it again.
