Calories/Carbs/Protein question

Hi,

Just got a quick question,

from what i understand:

- Protein contains 4 calories per gram
- Carbohydrates contain 4 calories per gram
- Fat contains 9 calories per gram

but when you read the nutrition info from food packages it doesnt actually add up properly :S any idea why that is??? If you go with the above euqation it turns out to have more calories then it states on the packaging, am I missing something?

    Agreed.

    But maybe 4 or 9 cals per gram is an estimate and not 100% fool proof.

    From my experiences it does round about add up.  Unless you provide examples then it's not possible for us to comment
