1 pt is approximately 50 calories.
1 g. fat is 9 calories
1 g of carbohydrates is 4 calories
1 g. of protein is 4 calories
I would say if it was a non-fibery food, it would be 40 calories of protein and carbs (you get to chose what the ration of those 10 grams are) and 1 g. of fat (fat has 9 calories per gram).
It depends on the calories, fat and fiber. Something with, say 100 cal. 3 fat. 0 fiber is 2 Points, whereas if the same item had 4 grams of fiber, it would be one Point. Hope that helps...
