I use steel-cut oats and on my package, it calls for water in the recipe. Water has no calories, so I use the amount on the package to calculate the amount per serving. If I add anything to it, I just figure out the points for what I'm adding and add it to the oatmeal total. I like to sweeten mine with agave nectar [which I have in different flavors] and I add in different spices or fruit or nuts to add flavor. You can use the liquid flavorings to add flavor as well
Hope that helps.
