Dear Antonia, There's an old saying: "Breakfast like a king, lunch like a prince, and dine like a poor man." In most countries, dinner is the biggest meal of the day. So why does this saying tell us to eat a large breakfast instead?
The answer is in the word "breakfast" itself. It means the "breaking" of a "fast," or a long period without eating. The time between dinner and breakfast can be more than twelve hours, so the meal that breaks your fast is very important. It should be healthy and nutritious. Also, unlike your evening meal, the food you consume for breakfast gives you the energy you need during the most active part of your day. Researchers have found evidence that eating a big breakfast can improve your concentration and mood, and boost your energy level
