True, but when you look up the calorie counts, whether online or in a calorie counting book - the calorie counts for both raw and cooked are usually available. You just need to make sure you're using the right one. Often it doesn't matter which you use, but sometimes it will.
If for example, you cook a lean hamburger in a skillet, and there's no fat or juices left in the pan, it won't matter whether you weigh it before or afterward - the calorie counts are going to be virtually identical (except that 6 ounces of raw burger, will become about 4 ounces of cooked burger - but if there's no grease in the pan, the only thing you've lost is water).
If there's a lot of grease and liquid that's going to be cooked out of the meat, and not eaten, or if you're going to trim the fat after cooking - then weighing after cooking makes the most sense.
And as Rosinante has already mentioned, if it's going to be used in a stew, soup or casserole (where you're going to be eating, what would have cooked out of the meat), then weighing before makes sense.
For example while 6 ounces of ground beef will cook down into a 4 ounces hamburger - the calorie counts for a cooked 4 ounce burger has already subtracted the fat that would have cooked out of that burger. However, if you're using that hamburger in a stew or casserole, that uses that fat (calls for undrained hamburger), then you need to use the raw measurement, because it will be more accurate.
A great example is bacon. If you cook it crisply, a slice has about 40 to 50 calories, but if you dice that same slice to saute vegetables in, you would use the raw calorie count (about 100 - 120 calories), because you're eating the bacon fat you otherwise would have left behind..
