Despite all the interesting advice in this thread the thing that helped me the most was accepting and getting used to the fact that if you're going to lose weight you're going to be hungry.
You're not starving to death, you're not dying, but there are times where you're going to just have to be hungry and deal with it. Our bodies are very good at doing their best to keep us alive, and hunger is our bodies way of saying "we need to look for food". The problem is we didn't evolve that skill at a time when looking for food only takes a few minutes and can involve thousands of calories.
If you're overweight your body is going to sound alarm bells that it's eating into the reserves, but you need to acknowledge that and let the reserves get used so you can lose weight.
