Stay with your original for these reasons:
1. Your first instinct is usually your best.
2. It's a personal blog, so should reflect your way of speaking, not necessarily some 'perfectly correct' grammar.
3. I think it best expresses what you want to say. You're right that 'eating cleanly' sounds like you just want people to be tidy, and 'move free' sounds more like a statement on Human Rights than about exercise.
Keep it simple and make it your own voice, your own words- go for it!
