USAGE:
完食 is relatively informal and became popular in food-related media and social media. It implies a sense of achievement, as though finishing a meal is a challenge completed.
COLLOCATIONS:
- 大盛りを完食する — to finish a large serving
- 完食できる — to be able to eat everything

NOTE:
完食 contrasts with 残す (to leave food behind). In Japanese dining culture, leaving food can be seen as wasteful, and 完食 carries a positive connotation of not wasting food.
