I've been working in a food-related ad agency in LA this past year. Near where I sit is a huge cupboard of food, regularly replenished, and a freezer full of ice cream. Much of this is either a client's brand, or is bought in bulk from Walmart or Office Depot. i.e. it's mostly junk.

As a result I've been eating junk food. Lots of it. I eat heavily salted peanuts, 'oatmeal bars', chips and of course lots of ice cream. I've probably gained about 10 pounds since starting here!

But what I'm strongly noticing lately is how HUNGRY I am, all the time at work. I munch and munch - yet feel very empty. So an hour or so later I browse the dismal supply and choose yet another salty, high sugar and fat, low-nutrition item containing more trans-fat than I would ever eat normally.

This constant intake of junk with constant craving for more is a new experience for me - normally I'm a pretty sensible eater.

I can TOTALLY understand how poor people can become obese, in a desperate attempt to extract some small amount of nutrition from the thousands of cheap calories consumed.

For various (mostly good) reasons it's difficult for me to make sensible choices in this situation, and I'm tempted to quit this otherwise great job just to save my health!
