So we all know meat shrinks when it gets cooked. Does this change the protein/carb/fat content of the meat? The fat content changes since you can see it left in the pan, but what about protein? Obviously there would be less calories if there is less fat

Well I did some experimenting earlier today. Did a slow-cooker with a pork loin. Precooked weight was 1615grams. Postcooked weight was 1042grams. Liquid weight was 573grams, which included a bit of water that I put in. SO, a precooked serving is 100grams, which is what the package labelling is based on.

So I took 1042/16.15=64.5g, and 573/16.15=35.4g.

so 64.5g of cooked solid, and 35.4g of cooked liquid, equals 1 precooked serving, 100g, so if you measure this out, you can use the label as a guide again. make sense?

Anyway this would definitely explain why it seems I've hit a plateau, not being able to break the 180 mark and stay there. 65g of meat ain't much when it's on a plate lol the size fools you-I think I had been putting more like 300g on, which is like 4 servings, times two meals.

As for losing other vitamins/minerals/protein in cooking, I have no idea. But I'm satisfied now that I'm capturing all the fat & calories.

You can't use the cooked values to and relate them to the precooked ones that you're referring to, because as you said, you've lost water, some fat, and probably some other (though possibly negligible) amounts of other nutrients.
 
Yeh, I lost the water and the fat, but collected it. So proportionally it still all makes sense. For example if i have a precook weight of 1000 grams, and after cooking I have 500grams of solid and 500 grams of liquid, then i could take 50 grams of solid and 50grams of liquid, and make one 100g serving as per the label. It's just in a different form, I didn't dispose of anything. ((shrugs)) makes sense to me??

I get what you're saying. We might not be on the same page here, but what I'm thinking is that the macros on the nutrition label are for 100 grams of the precooked, right? So even if you do your calculations, when you get back to 100 grams of cooked, it's not the same.
