If one serving of 2% milk is 125 calories, and 45 of those are from fat, how many calories should skim milk have when only the fat is removed?
If it's 2% by volume, then I'd say 80/98=X/100 or X=81.6+ calories per serving.
Nice. Oddly though, it ends up being between 85 and 95 (for the serving size I described). I wonder where the discrepency is.
Maybe if it's under .5% they are allowed to round down, so they don't go to the trouble of getting all of it out.
Skim Milk also isn't 100% fat free. It has to be .1% or less fat to use the label but you probably still have a few calories from fat in there.
I didn't do the math but if 2% milk has 45 calories from fat I would think you'd still have 4 or 5 calories from .1% milk.
I just looked in the fridge and I'm more confused.
1%: 130 calories per cup, 20 calories from fat
skim: 90 calories per cup, 0 calories from fat
So, take away the fat from a cup of 1% and you have 110 calories, but a cup of skim is only 90 calories.
Umm, that's odd 1% milk. My 2% is actually 120 (or somewhere around there).
I wonder how many corners they are allowed to cut when they make those labels.
