Jen, I have the same question as John, we can't answer your question without knowing what your other protein is, and whether or not it is a fat free protein.
For your 1 cup of plain nonfat yogurt, you would count that as 2 blocks of protein and 2 blocks of carb. You need to add fat, so you would add 6 almonds for your fat blocks--but since your protein is fat free, you would double this and add 6 more.
If your other protein is fat free, then that is another 6 almonds-3 for your fat block and 3 more for the "missing fat". If your protein is NOT fat free, you would just eat 3 almonds.
So, for your entire breakfast, you would eat a minimum of 15 almonds, and if your other protein is fat free, then the total amount would be 18 almonds.
