I have been using Fitday.com to track my eating and today I went to add a custom food and it balked.

I have these whole wheat flour tortillas that have 2g fat, 12g carbs, 8g fiber and 3g protein.

Fitday says they should have 46 cal. The package says 80 cals. Whats a girl to do to get fitday to accept the darn thing? Remove the fiber grams and make it 80 cals, or change the overall cals to 46?

Good Grief! What is the reason behind (carbs-fiber)x4 to compute cals anyway?

Maybe it has something to do with the serving size. I've had Fitday correct me once or twice, until I realize I had to adjust the serving size.

Sometimes when a product is marketed as low carb, they subtract the fibre from the carbs right on the nutrition label. Maybe you need to add it back on (enter 20 grams of Carbs). And be careful of the word "NET". "Net Carbs" is carbs after subtracting Fibre and Sugar Alcohols.

My daughter is on an insulin pump, and these bad labels on low-carb foods have screwed up her blood sugar a few times.

I had the right serving size - 1 tortilla. And the net carb thing - they actually touted the tortilla as having 4 net carbs - but it wasn't done that way on the nutrition info. :confused:

I would guess that Fitday is probably right, and somebody in the marketing department wrote the nutrition label.

There is quite a bit of controversy over how low carb foods should be labelled. Companies get really creative to get the number as low as possible.
