Paul urged them to eat some food, so they did and then lightened the ship.

Acts 27:33-38

33 Just before dawn, Paul urged everyone on the ship to eat some food. He said, “For the past 14 days you have been waiting and watching and not eating anything. 34 So, now I urge you to eat some food. We (inc) need to do that in order to stay alive. I tell you to do that because I know that none of you will drown [IDM].” 35 After Paul had said that, while everyone was watching, he took some bread and thanked God for it. Then he broke the bread and began to eat some of it. 36 The rest of us became encouraged, so we (exc) all ate some food. 37 Altogether there were 276 of us [SYN] on the ship. 38 When everyone had eaten as much as they wanted, they threw the grain that the ship was carrying into the sea, and this made the ship lighter.
