A clean diet can be a little bit different for everyone but there is one thing that all clean eaters would agree on: The white stuff has to go! This includes all white sugar and white flour products. These foods provide absolutely no nutritional value. Whole foods actually fill you up and fuel you, whereas the white stuff fill a mental craving but don’t physically fill you up. These foods also make it very hard to keep your blood sugar levels stable. When your blood sugar is too high or too low it will cause cravings and may also cause symptoms like irritability and fatigue. This will make staying on a clean eating plan more difficult.
