nutrition confusion

I am forever trying to lose weight..I feel like i've been fighting the battle of the bulge my whole life. This is really not the case as i've seen pictures of myself from elementary and high school and I was actually a very healthy and fit child and adolescent. I don't understand where it all went wrong for me. I've tried to pin point exactly the time and place that I went from "healthy" to "way not healthy" and I just can't figure it out. The year before I got pregnant with my second son I had gotten serious about getting healthy. I wasn't concerned about being thin and gorgeous I just wanted to be healthy. So I joined sparkpeople and I got serious about counting my calories and started the slow process of changing what and how I ate. It took me about a year to lose 60lbs but I lost them in a healthy way and I was proud of myself for sticking to it for so long.

Now I've had Magnus he's going to be 8 month old soo and I have 100lbs that I would like to shed. As ALWAYS nurtition is my downfall. It has always been to hard for me make those healthy choices when i'm at home. When i'm at work I feel like people are always watching me and my co-workers and my boss's are very supportive of thier staff so eating healthy at work was never a problem. I would pack my lunches and breakfast and two snacks and i'd do real well during the day..then i'd get home and blow the whole enchilada!! I'm determined NOT to do that this time. I know that I do enough exercise in a day to lose weight I also know that my nutrition really needs some work. So i'm SLOWLY changing how I eat and i'm making it a game of sorts to see how many colors of the rainbow I can eat in a day. I kind of sort of know that principle of healthy nutrition but really i'm pretty clueless. thing that I thought were good for you turned out to not be so good after all. So to that end I am seriously contemplating calling my health insurance and seeing if they cover nutritionists I mean they should they cover Jenny Craig. Then I'd like to check into some of the health and wellness classes that are offered through St.Johns Medical. I would like to be at least 20lbs lighter by this summer and I think this is doable.
