it's pretty much as it sounds...eating foods that are clean; free of chemicals, pesticides, etc.
i would have to say that 50% of our eating here is clean, but need to bump that up to at least 90% (because, honestly, i'm not going to even try to give up diet coke...yet.) it seems more and more the foods you find in our stores are loaded with preservatives; i began to wonder why the bread i bought a month ago, still hadn't molded. don't be fooled by whole grain or multi grain breads...some brands are still laced with preservatives, case in point....the loaf i had.
i already workout 5-6 days a week, eat 4-6 times a day (3 meals and snacks in between.)
it really just requires more prep and organization, and i love being organized!
