Hi L.,
Congratulations on deciding to be healthier. I've picked up a few tips over the years that may be helpful. Some are foods to try, and others are just general tips.
Substitute ground turkey for ground beef in recipes. It works best when the meat is going to be seasoned, especially in taco/burrito meat. The texture is a little different, but it's much less greasy.
Drink LOTS of water.
Dill pickles are a great way to satisfy a salty craving. Low cal, no fat and cucumbers are veggies.
To help with portion sizes if you buy crackers, chips, cookies, etc. Buy some snack size plastic baggies, and divide the snacks into servings. You can count pieces or use a scale to speed things up. Then you just grab one baggie for a serving and don't have the temptation of going back to the box for more.
Skinny Cow ice cream sandwiches are great!
I've never tried this one, but I have a relative who uses nonfat coffee mate powder and butter buds to provide the dairy flavor in instant mashed potatoes, using water for the liquid. Not sure how it tastes, but she likes it.
Use smaller plates at mealtimes. It will make it look like you're eating bigger portions than you are.
A spoonful of chocolate chips can help satisfy a craving for rich and chocolatey...if you can do just one :)
Sugar free pudding and cool whip with fruit can make a very yummy dessert without blowing your eating plan.
In restaurants, ask for a box with your entree, and put your "leftovers" in it before you start eating.
If you like to cook, there was a show on the Food Network a few years ago called "Calorie Commando." The host was annoying, but the few recipes I tried were pretty good. The recipes may still be available on the foodnetwork.com.
I like "The Weight Watchers Complete Cookbook" http://search.barnesandnoble.com/Weight-Watchers-New-Comp....
I also have a Weight Watchers "cookbook" that I found on the magazine aisle a few years ago. They may have something similar available now. It is only recipes--no articles or ads--that are quick, easy and use fewer ingredients than the full cookbook I have.
Use dry seasoning rubs to flavor meats. My favorites are lemon pepper for chicken and fish or creole seasoning for chicken and pork. They add lots of flavor without adding calories.
Plan ahead! Make a menu of meals and a shopping list before you go to the grocery. You'll be less tempted to buy something not on the list because it looks good, you'll always have everything you need to cook dinner (no emergency burger nights), and you'll save money.
Splurge on a few sessions with a personal trainer at your gym. You'll receive the education you need to make sure you're doing the right kind of exercises with the correct form to be successful.
Good luck!
