You can do good work simply staying up all night and eating nothing but junk food, but probably not in the long term.

Junk food drags you down.

Anyone who can fail to rejoice in the enticing squish/crunch of a fast-food French fry, or the delight of a warmed piece of grocery-store donut, is living half a life

I was always a junk food person, still am.

Everyone would be healthier if they didn't eat junk food.

I eat whatever I want, junk food included.
