Are there any effective detoxification drinks for weight loss?

Not in my opinion: Detoxification, especially of "colon" and "liver" are widely thought by non-traditional practitioners to be of benefit, but there is zero evidence in medical literature that any of these techniques (cathartics, purgatives, liver "cleansers") either work or are needed. Some may be harmful. The colon does not carry poisons. A sensible low calorie diet and exercise are what is needed!
