I always grill up a bunch of chicken or steak at once, then freeze what I don't plan on eating right away. That way, when you're ready to make some stir fry or some kind of simple dish you can just thaw it out and heat it.
Also, instead of snacking on chips or sweets try grabbing some almonds. I eat them everyday and they are soooo good for you! Another way that a friend of mine slimmed down was by adding a lot of crushed ice to her beverages. That way you get less calories from the beverage (soda, juice, etc) and you actually burn calories by chomping on crushed ice.
Hope this helps!

I love to bake too, it's like therapy, I try to find ways to modify favorite recipes to lighten them up. Try using evaporated skim milk in cream sauces. I also use it to make a simple bread pudding using mostly egg whites with whole grain bread and Sugar Free caramel ice cream topping in the bottom of the pan, when you flip a servng over it is like having a caramel roll without the guilt.
