Fats and proteins can also provide us energy. For this to happen:
1. Fats and proteins must first be converted to glucose
2. Fats and proteins must enter separate catabolic pathways of their own
3. Fats and proteins must be modified to forms that can enter the glucose metabolic pathway
4. Fats must first be converted to proteins that can enter the glucose metabolic pathway
