One scoop of Precision Protein powder will give you 10 calories
of carbs (2.5 x 4) per serving, and 80 calories of protein (20
x 4) per serving. Getting the TRUE fat content is a little more
tricky.
Because most Americans are so fat conscious, food manufacturers
try to give their products more appeal by making them low fat
(or at least appear so). When the labels says "low fat",
that does not necessarily mean that it is true. When a product
says "low fat" it is usually referring to the total
fat calorie amount per serving.
So, if a product has one 1 gram of fat, it has a total of 9
calories of fat per serving (one gram of fat equals 9 calories)
and can be labeled low fat. Seems ok, right? Well, we don't
know yet, since this is not the complete way to determine the
actual fat content of the product. To really know if the product
is low in fat, you must take into account the TOTAL number of
calories per serving that the food provides.
So, if the product has 9 calories of fat per serving and the
total calorie amount per serving is 18 calories, then the product
is 50% fat per serving. Would anyone who wants low fat foods
knowingly eat a food that is 50% fat? Of course not. But people
do it all the time because they see it labeled as "low-fat".
To get the true fat amount you must take into account
the serving size.
Fortunately, this product is 100 calories per serving, so that
means that each serving is 9% fat. This product is actually
low in fat, low in carbs and very high in protein.
