What are the benefits of a liver cleanse?

Not Medicine: I doubt that any physician recommended a "liver cleanse". In my experience this can mean a thousand different things. But, i know of no physician recommending this process.

What's your goal?: I'M ALL FOR IT IF by "cleanse" you mean adopting a healthy lifestyle with routine exercise, cutting out tobacco, reducing alcohol & sugary drinks, minimizing highly processed foods & fats, & adding in lean proteins, whole fruits, vegetables, & nuts. DON'T DO IT IF instead you mean taking some fad diet, enema, colonic, or purgative to lose weight or supposedly rid your body of unspecified "toxins."
