Yes. I've done it. I've put myself on the path to eating healthy. correction. Manwell put me on the path to eating healthy by recommending a rather remarkable and free (did I mention it was FREE) website to do it for me. It has an awesome nutrition/calorie counter and there's loads of support available should you need it. See for yourself the site's called Spark People.
Cheesy infomercial-ness asside the site really is a great source of information. So far I haven't even had to give up my favorite foods!
