Getting Healthy

For a long time I've thought about wanting to be more healthy. It's very difficult. I grew up in a family full of overweight people. We enjoy big meals and sitting around watching movies and TV. My favorite foods are pizza, popcorn, chips, and soda.
I've tried from time to time to eat more healthy and exercise. But it's just so hard for me.
I need to. The way I'm going now I am at increased risk for illnesses such as heart disease, diabetes, and probably cancer. Plus I just feel yucky. I'm only 25 but my body feels so old. In all of my biology classes, I've learned about how the body works and how it uses what I put in it to perform different functions. There is so much I put in it that gets in the way of it functioning properly. And not just physically. Emotions and mental processes are affected as well. I'm sure that a lot of my depression is a result of the things I put in my body.
I don't want this to be about dieting or losing weight. I want this to be about changing my lifestyle and taking better care of myself. I know this body is only temporary but it's temporary for another 50 years maybe and to me that's a long time.
I will have to overcome a lot of stuff to do this. Old, bad habits, eating when I'm depressed and stressed, the attitude that I shouldn't worry about my body. . .lots of stuff. But I want to do it. It's time.
So I decided to start a blog dedicated to the journey. I didn't want to mix it in with my other one. I think writing about it will help.
My goals:
1) I want to make this about changing my lifestyle. This is NOT a diet.
2) I want to cut out junk food (I did pretty food for about two weeks about not drinking soda).
3) I want to exercise for at least 30 minutes 3-5 times a week.
4) I don't want to deprive myself of things I enjoy, just cut down.
5) I want to learn to love who I am, flaws and all. (I think taking better care of myself will help do that)

So more to follow. Please join me in my journey. Any tips and encouragement is greatly appreciated! :)
