What is your biggest weight-loss food challenge?

Today is the first official day of my diet!

So....

I wanted to know, what is everybody's biggest food challenge?

Last week, I was keeping track of my calories to see where most of them go, and to my surprise, I discovered that a HUGE number were going towards beverages: Soda, iced tea, juice and milk. (I .love milk - I guess I will never have to worry about osteoperosis - lol) We're talking hundreds of calories here. I guess I must get really thirsty during the day.

So for me, it would have to be beverages. I am going to replace most of them with water, and my beloved whole milk with skim (this'll be hard because I would drink heavy cream if I could - I know: Gross!).

What about you?

PS - It would have been chocolate, but there is just no way I could possibly cut chocolate. How would I live?!
