The reason this happens is due to blood sugar levels. The amount of glucose thats in your blood at any given time.
When you eat a meal thats high in carbohydrates (grains, potatoes, fruits) they are broken down into simple sugars and absorbed into the blood stream. This causes a spike of sugar into the blood and is what gives you a short sugar high, however shortly after it's usually followed by a sugar low and this results in low energy and a grumpy, irritable mood. The more processed/refined a carbohydrate is the quicker this happens. The quick high, followed by a quick low happens due to the hormone insulin attaching to the sugar molecules and taking them into the cells for safe storage (AKA fat storage). When this happens theres often not enough sugar left in the blood stream which is what causes the "sugar low".
