The heaviest turkey ever known was 86 pounds, according to the University of Illinois. To put that weight into perspective, the average turkey consumed on Thanksgiving weighs 15 pounds.
The average 15-pound turkey contains about 70 percent white meat and only 30 percent dark meat. After a large meal, the most popular way to use the leftovers is to use them in a sandwich, according to the University of Illinois Extension. The second most popular way to use leftovers is to make a stew. Turkey is a great protein source, and it has more protein than beef or chicken. It is also low in fat.
