I weigh my food in order to calculate carbs based on weight and nutritional label,
and subtract fiber grams.
if you are taking the trouble to get a scale and weigh
stuff, then be accurate to the gram. otherwise, throw out the scale and eyeball it
it may be easier to just weigh it, and if it is over by a few grams just eat it, but record
the actual number of grams, instead of trying to scoop out a gram or two. that way
you can make up the balance later in the day, either skip something or take an extra
