I've noticed that when I scan in pre-packaged food and switch the measurement to weight (in grams) the nutritional values are off.
For instance, when I scan in Chobani Nonfat Plain Greek Yogurt, the default serving size is 3/4 cup. This is 90 calories. However, when I adjust the serving size to 170 grams (which is what Chobani lists as the same serving size as 3/4 cup), FitBit changes the calories to 67. This makes no sense if it's an equivalent measurement of the same serving size, and it's very frustrating.
It seems to do this for almost all food. I like to weigh my food to get a more accurate account of what I'm eating, but then the FitBit app is making the calories consumed LESS accurate. Why is this?
I tested this in the Lose It app and it treats the serving size of 3/4 cup and 170 grams as the same, both at 90 calories (as it should). So does My Fitness Pal and Macros First. Why is FitBit not able to do the same?
