How much is the weight of a 1 pound raw pork tenderloin reduced when cooked?

This means that a 1-pound raw tenderloin will likely weigh about 0.7-0.75 pounds after cooking.

However, the actual weight loss can vary depending on several factors, including:

* Cooking method: Dry heat methods like roasting or grilling cause more moisture loss than moist heat methods like braising or poaching.

* Cooking time: Longer cooking times lead to greater moisture loss.

* Internal temperature: Cooking to a higher internal temperature will result in more moisture loss.

* Fat content: Leaner cuts of meat will lose more moisture than fattier cuts.

Keep in mind that this is just an estimate, and it's always best to weigh your pork tenderloin before and after cooking to get an accurate measurement.
