I am vigilant about keeping a food diary. I write down every single bite of food that I eat, and I use www.Fitday.com
, a free on-line carb\calorie\nutrient counter, to do it. It's been the most helpful tool I've ever had in my weightloss journey.
By law, if it's between 0 and .5, it can be listed as no carb, if it's between .5 & .9, it can be listed as <1. There are some 0 carb foods, but check the portion size on the label to be sure that they are not listing a rediculously small portion as a serving to keep the carb count on the label low. Also, beware of sugar alcohols. They say on the package .5 net carb or .5 net impact carb, but they are subtracting the sugar alcohols. Sugar alcohols count! Your body processes the carbs, it just absorbs them more slowly so your blood sugar doesn't spike. If you're a diabetic, that's what you're looking for, but for LCers, that's not the point. That said DO subtract fiber. The human body doesn't have the ability to extract nutrients, calories, carbs etc. from fiber, it's just bulk.
I think that's TMI, but I'm on a roll LOL
