I am an after cooking kind of gal, because a 5 ounce hamburger patty grilled shrinks down to a little over 3 ounces, so 3 ounces of raw grilled would be.
I always weigh mine after cooking too but someone in my office questioned me about it last week and I was like "hmmm". Then it got me to thinking about Myfitness Pal and wondering if the ounces, etc. that are referenced there are pre or post cooking.
