Final answer:
Cooking roasts can result in a weight loss of 5 to 25 ounces, with the exact amount depending on various factors such as the size and cooking method.
Step-by-step explanation:
The question regards the quantity of weight loss in ounces when cooking roasts. However, it's important to clarify that the answer could vary significantly based on the size of the roast, the cooking method, and other variables. Cooking leads to moisture loss, and it can range typically between 5 and 25 ounces, depending on the initial weight and type of roast. None of the reference information provided on weights and weight loss directly answers the question, but it is worth noting that the weight of food (such as roasts) does decrease after cooking due to moisture and fat loss.
