Skipping breakfast is not a good way to lose weight. After 8-12 hours without a meal or snack, your body needs to replenish its supply of glucose, or blood sugar. Both your muscles and your brain rely on glucose to function. Your brain can not store glucose so it must have a fresh supply. In order to do mental work and any activity through the day, you need glucose.
Studies show breakfast eaters have better attitudes and higher productivity in work and school.
They also have more strength and endurance and better concentration and problem- solving abilities. Those who skip breakfast often feel tired, irritable, or restless in the morning. Breakfast eaters are also less likely to be overly hungry for mid-morning snacks or lunch and, overall, they tend to eat less fat throughout the day. It is true that eating breakfast may cause you to feel hungrier at lunch. But that's because your body reverts back to its normal metabolism.
