ok, i think i got it, but i'm still kinda confused. so i want to stay under 25% fat for the whole meal? let's take your example of peanut butter...57% for the peanut butter and let's say the bread, for two slices, has 18% fat. then i have a glass of vanilla soy milk which has 45% fat. now how do i calculate the total % of fat for the whole meal?
another question...do i for the most part need to stay under 25% fat for everything i eat,not just the whole meal?
