rubbish food

Food that is unhealthy, fattening or has saturated fats.
Basically, a food that you wouldn't eat on a healthy diet

I've been really bad this week and ate nothing but rubbish food

Shitty food

Food that makes you feel unhealthy, fat or bloated. Normally packed with carbs and saturates but tantalises the tastebuds, a well deserved treat!

I should go to the gym but I really fancy some shitty food right now
