Tony and I tend to snack on fruit through the day, then have one main meal at night. I have to take a lot of medication in the morning, so I might have a hard boiled egg, a glass of milk or maybe a couple of slices of lean ham before that, as some of the meds need to be taken with food. However, we're in Spain and it's hot at the moment. When we're in the UK, we tend to have two meals a day - usually a late breakfast/early lunch and then a main evening meal around 7.00pm. It works for us, because we don't do hard physical work or lead very busy lives.
That said, we had breakfast in a local cafe this morning, and I'm now feeling hungry, and it's only 2.30pm!
