Please make the portions consistant?

some times the portions are in grams, or ounces, leaving the question how many ounces equal a portion. Please make the serving simpler, it is so frustration to make the conversions and most times I'm guessing. And when you are trying to loose weight, which is already very frustrating, to have to do the calculations and additional research can make you just give up. We really need that aspect of this program to be very, very easy
