We’re not going to tell you junk food is bad for your body (you already know that).
We’re not even going to tell you junk food is bad for your brain (you probably figured as much).

For one thing, a new study suggests that a diet high in fat and sugar (for even a relatively short length of time) changes the chemical activity in the brain. After just six weeks of being fed a diet high in fat and sugar, mice showed chemical changes in the brain associated with depression. The mice also showed signs of anxiety, and higher levels of stress hormones, as well as higher levels of a molecule associated with patterns of reward and withdrawal.
