It's likely that your meal sizes increase throughout the day. Most people opt for a bowl of cereal for breakfast, maybe a sandwich or salad for lunch and a large dinner in the evening. However, according to scientists, we have been eating in the wrong order all along.
It turns out, eating more of our calories earlier on in the day can be good for our health. One study found that women lost more weight when they ate their lunch earlier in the day whilst there was a link with eating breakfast later in the day and a higher body mass index (BMI).
Speaking to BBC News, Dr Gerda Pot, a visiting lecturer in nutritional sciences at King's College London said, "There's already a very old saying, eat breakfast like a king, lunch like a prince and dinner like a pauper, and I think there's some truth in that,".
Scientists believe this could be down to our body clocks, and whilst most people believe this is associated with our sleeping patterns, there is also a clock for our mealtimes. Dr Pot, who studies chrono-nutrition, said: "We have a body clock that determines that every 24 hours each metabolic process has an optimal time when something should happen.
"That suggests that having a large meal in the evening is actually, metabolically speaking, not the right thing to do because your body is already winding down for the night."
This research is important in fighting obesity in the UK as it could mean people who are trying to lose weight may not have to change what they eat, but just change the times they eat at.
