Theophylact of Ohrid — as excerpted in the Catena Aurea on Mark 8:1-9

“The multitudes who ate and were filled did not take with them the remains of the loaves, but the disciples took them up, as they did before the baskets. In which we learn according to the narration, that we should be content with what is sufficient, and not look for any thing beyond. The number of those who ate is put down, when it is said, And they that had eaten were about four thousand: and he sent them away; where we may see that Christ sends no one away fasting, for He wishes all to be nourished by His grace.”
