It depends on what Im making. If a recipe calls for raw, I use raw nutrition counts and weigh it raw. Since I only cook for myself, If I am eating a chicken breast or something, I'll measure it raw since I don't want it get rid of an ounce or some such because I cannot guess cooked weights from raw and I don't want to keep an ounce or something as leftovers. Ground meat I generally do cooked as I cook up a large batch and then portion it out. Im not going to separately measure out 3 oz, cook it, measure out the next. Too much work. Much easier to cook, measure, bag, freeze.
