@ThirteenSteps: I tend to disagree. I also weigh cooked meats before logging the nutritional values on SparkPeople. Cooked meats DO contain less fats and such (in liquid form). I simply cook the meat first, drain off the excess liquids (you can see the fat floating in the liquid), then weigh it. Less fat, less calories. That 6-oz 93/7 burger patty (at 170 calories per 4-oz) becomes around 4.6-oz cooked, thereby meaning fewer calories and fat.
But that's just my opinion.
