If you start with 1 lb raw meat and cook it how much will have?

When you cook raw meat, it loses moisture. The amount of moisture lost can vary depending on the type of meat and how it is cooked, but on average, you can expect to lose about 25% of the original weight of the meat. So, if you start with 1 lb of raw meat, you can expect to have about 0.75 lb of cooked meat.
