What speckla said, eat vegetables as a snack. In between meails, eat fruit as a snack, make sure to eat at least 3 pieces of fruit a day.
Eat less meat. Twice a week is enough.
Eat eggs for breakfast (no may or salt or use celery salt instead, not because it's necessarily healthier, but because one tends to use less of it), since they'll prevent hunger and provide a lot of protein.
Avoid anything processed that says "light" or "low fat" (ie chips, cookies etc etc). Sounds weird, but sugar substitute makes you hungrier and low fat usually has a lot of other bad stuff (such as sugar or salt) to compensate for the lack of fat.
