Why do we eat? • Glucose
• Use 20% of our energy

But, if we only need it for energy, why do we eat a variety of food?
Hunger Energy to group and develop (mentally and physically)
Varying types of food support everyday bodily functions
Brains needs oxygen/ blood supply for neurons
Nutrients Components of molecules that repairs tissues and organs
Hypothalamus Controls the metabolic rate – important for food consumption

Why do we eat when we
are not hungry?

is persistent over an extended period of time
