When I first started exploring nutrition for myself, I had a hard time wrapping my head around the idea of a detox. It scared me. My initial and only exposure to them was juice fasting.
I saw a lot of people really struggle with juice fasts. I saw it first hand working at a raw food detox center. I finally tried it and it was awful. I lasted 2 days before deciding it wasn't for me.
And once I had more nutrition training, I discovered that a detox does not have feel like your are being deprived. You can take steps to prepare your body for deeper detoxes.
The best way to start is with healthy, balanced meals. From there, you can go deeper.
