Hooey, garbage, a waste of money, and unhealthy.
But let me tell you how I really feel about it.
Seriously - detoxes are a bunch of bs. There is no scientific evidence ANYWHERE that a detox does anything other that put you on a starvation diet for however many days, cause you to drop incredible amounts of water weight, and be totally ineffective.
Anythign you lose after doing a "detox" diet will just come right back as soon as you start to eat any kind of real food again.
And as for the whole concept of "detoxing"? The body is perfectly capable of detoxing itself using liver, kidneys, lungs, etc. That's what your body is designed to do - use the nutrients and excrete anything else.
If there REALLY were that buildup of "toxins" in your body, do you really think drinking lemon water and salt water 6x a day is going to be the cureall for it?
