Well, there's a website I use called The Daily Plate
Where you can look up all the calorie contents of your food, and log them down
I've found that it makes you more conscientious of what you put into your mouth
And how many calories are in the foods you eat every day
I'm a very visual person, so just seeing those numbers helps me make better decisions
(it's also a pain to log in the food :P)
Other than that?
I LOVE Healthy Choice frozen dinners
(as long as I put salt and pepper on them)
And if you go to the grocery store and buy some plain chicken broth, it's very low calorie and very filling

I also love popsicles
There's some plain ones that are around 15 calories each, and kill my craving for sweets
Hope that helps some!
