Is a restricted diet leaving you feeling tired and miserable?

The brain and central nervous system can only utilise digested carbohydrates (glucose) as a source of energy. Proteins and fats are chemically unrecognisable to the brain and central nervous system. Brain functions including the ability to think, learning and memory are dependent on glucose.

Good sources of carbohydrates include, oats, whole grains, potatoes, sweet potatoes, vegetables, fruits and legumes like beans, lentils and chickpeas.
