Is the 14 day "cleanse" detox a scam.

Cleansing: Yes. Of course. Your body had three systems at least that keep you 'cleansed'. These are your liver, your kidneys, and your lymph system. Nature takes care of this. Now on a different note. If your diet is full of sugars and other unnatural chemicals then switching to a more natural and healthy diet may increase energy and stamina.

Define "cleanse": 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."
