You may have some sort of mineral imbalance in your system. If you do, once you figure it out and begin to balance your minerals (more is NOT always better and taking one will imbalance another as minerals act antagonistically with their counter part ex: calcium causes muscle contraction, magnesium causes the muscle to relax; sodium will tend to cause water retention, potassium water elimination. We need both).
In addition, I do not notice immediate weight loss after a liver flush/cleanse, but I have noticed a slow steady loss of weight after starting the flushes; probably due to a better functioning elimination system, including the liver.
