I know in weight loss the main thing is calories taken in vs. calories burned, but on food labels when they say "calories from fat", how is that information useful? Are calories better if they aren't "from fat" or are calories all just calories to be calculated the same? For example, say I have two similar food items, both 100 calories, but on one of them 45 of the calories are from fat while the other has 24 calories from fat, is one better than the other, or are they no different?
