Question about 1yr old who eats like an adult

My daughter is 1 and eats like a full grown man. Literally, she puts no food waste. She will eat what's on her plate, yours, and the next person's. I feed her table food/solid foods and she still stays hungry. For example, I fed her some mashed potatoes, with broccoli, and shredded chicken...she saw me with popcorn , screamed "EATTTT!!" ,and ate half my bag, and some fruit...she will have a stranger thinking she hasnt eaten in days!! And instead of going to sleep from being good and full she'll stay up and run around, full of energy, for at least another hour. Is this eating habit normal? Or is she just continously eating/saying she's hungry b/c she see's the food in her presence?
