The men were the masters of the house and family. During the day they would work outside of the house. If you were a poor man then you would have to start your day early in the morning. You would not have much for breakfast so you would just eat bread. Then for the rest of the day you would either work in a workshop or out in the fields.
If you were a rich man, you would have a big breakfast of bread, cheese, honey, and water. Before leaving for town, you would pray to the household shrine. The rich man's work might consist of writing letters to other Romans, seeing clients, and going to meet other businessman. After lunch you might take a nap, and finish your work for the day. In late afternoon all Roman men went to the public bathes, then went home to enjoy a meal with family and friends.
Hope I helped! :)
