Here's what happens when you don't eat a morning meal: Your body enters into a prolonged fasting state. It starts to believe that you won't be eating any time soon. When you finally eat lunch, your body stores it as fat because it thinks, "I'd better save this for later. I don't know when the next meal will come." That, of course, leads to weight gain. When you break the fast in the morning, on the other hand, your body can use that food to power you through the day.
