New to all this

I’m in my first week of this, and am a bit overwhelmed. I certainly need to eat a healthier diet, but I’m not much of a cook, and I can’t find many of the foods you folks recommend. For instance, I have no idea where to find SWG bread. I live in a smallish town on the Oregon coast, and have 2 stores to shop at….I also live alone, so it’s difficult to see how I can easily prepare all these small portions every day.
I must admit, I’m not good at being told what to do or how to live, so this will be a rather daunting challenge. I am beginning this by eating more “good” foods, and less “bad” foods, but this process will take a while.
It will take a bit of getting outside my comfort zone for me to become involved with a weight loss community or reporting my weekly weight- I’m not that social with people I don’t know…
I’m working on these things
Thanks, Dan
