Both husband and myself are now retired. We each eat on our own schedules. We eat when we each are hungry.
He might have a sandwich at 1pm, and his dinner will be at 7 PM. We do not eat meals together... we never have in the 39 years of marriage. We might eat the same meal....but usually at different times....when we are hungry, not by the clock.
I sometimes have a meal about 11am...yogurt with fruit or the like, but not always. Some days I only eat one meal in the day at at about 3:30pm. I feel better not eating a lot of food or eating all day long. I listen to my body more now that my day is unscheduled and calm, not like when I was working.
