Weighing Chicken, Fish, Meat etc

It depends on which nutritional information you are using. If you are always using the ones that say "raw" then weigh the meat before you cook it. If you are using nutritional information for pre-cooked foods, then you need to weigh it after.

Goo question. I've always wondered if the weight on MFP foos bank is before or after cooking. I know that at the fast food places everything is weighed before cooking. Like the quarter pounder is a 1/4 of a pound before cooking.
I just think 4 oz of chicken before cooking is such a small amount!

I am inclined to say after cooking because the water weight is cooked out of the meat. Up to this point though I have been weighing before cooking.

Like others have said, it depends how you are entering it. If you use the "raw" entry...weigh it raw. If you are using the "cooked" entry...weigh it cooked. I personally use the cooked version...you are only consuming what it weighs out at after it is cooked. Alot of moisture gets cooked out of it...which, obviously you do not consume.

I usually buy my chicken and fish at costco, the bag has the nutrition label but not sure if thats for raw or cooked? But it does seem like such a small amount after its cooked, Ijust want to make sure Im getting the right amount of protein

I think that is usually raw. Because I noticed mine will say something like 1 4oz fillet....and it will be 4 oz raw...but of course less after cooking.
