MyNetDiary and Fitbit – integrate your diet and exercise

MyNetDiary online and mobile diet program allows you to lose weight by tracking your food calories with the best nutrition database in the world. MyNetDiary estimates your activity calories if you enter activity type and duration.

Fitbit tracker uses an accelerometer to measure your activity automatically while Fitbit weight scale automates your weight tracking.

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

  1. MyNetDiary shows the activity calories and weight measured by Fitbit.
  2. Fitbit shows your food calories measured by MyNetDiary.
We highly recommend using Fitbit for activity and weight tracking while achieving sustainable weight loss with MyNetDiary.

How linking works?

Fitbit devices measure, collect your activity and weight data and transfer them at Fitbit website. MyNetDiary stores your food entries logged online or via mobile apps. By creating a link, you authorize MyNetDiary website to call 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:
    • Meals’ food entries (with particular food name, calories, fat, fiber, carbs, sodium and protein content).

Your data is transferred one-way after linking:

  • Fitbit activities and weigh-ins are transferred to MyNetDiary
  • MyNetDiary foods entries are transferred to Fitbit.

You should have MyNetDiary Maximum account in order to link with Fitbit.

Exchange details

What happens after I link?

After you link to Fitbit, MyNetDiary performs automatic data exchange once a day or within several minutes after you enter foods in MyNetDiary, one exchange per hour. In case you do not log foods in MyNetDiary for 10 contiguous days, MyNetDiary stops exchanging your data with Fitbit. When you start logging foods, MyNetDiary resumes Fitbit exchanges.

MyNetDiary exchanges last 3 days worth 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 scale measures body weight and body fat percentage. You may also enter body measurements like calf, chest, waist, neck, thigh, bicep, hip at Fitbit or MyNetDiary.

MyNetDiary downloads all these measurements from Fitbit. In order 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 case you would like to repeat Fitbit download for the last 3 days, please, unlink Fitbit and link it again.

Fitbit tracker counts daily steps and and may determine hours of sleep. While MyNetDiary synchronization with Fitbit these measurements are imported to MyNetDiary daily measurements from Fitbit.
