True meat weight/nutritional values after its been cooked?

[volatile]

Recently I have started weighing my meat fresh before cooking it and then weighing it again after its been cooked, something very interesting happened, the meat on average lost arond 1/3 of its original fresh weight!

Here is what I tryed:

180g chicken breast fresh, 120g chicken breast after it was cooked (loss of 60g!)

230g lean minced steak fresh, 150g lean minced steak after it was cooked (loss of 80g!)

OK so heres my question,

When the manufactuers say there product is say 24g protein per 100g does that mean if you cooked 100g of chicken breast that it would still contain 24g protein OR do they mean 24g protein per 100g AFTER it was cooked.

I hope the nutritional values dont apply when cooked as this is a HUGE loss in protein and will mean I will have to rethink my diet

Let me know, many thanks

Actually what is mostly lost in cooking is water and fat, much of it is cooked away.

So what does that mean? my 100g (24g protein) that has just been cooked and tuned tuned to roughly 60gs still contains 24g protein?

It should, unless you boiled all nutrition out of it. Fat and water tend to cook off, there should be negligent loss of protein.

Yes it contain the same protein values. All meats and fish have this counted in when weighed fresh. Take hamburger for instance. They give you a protein count uncooked for so much weight for 70%, 80%, 90% ect.

If it really bothers you, just look up the nutritional values for that particular product after it has been cooked. Usually you should be able to find something.
