Maybe I'm an outlier but I haven't been convinced, not having read double-blind placebo-controlled studies, that there are toxins or dead fat cells that can be flushed out by drinking water. I know that this has been taught for decades since the evolution of Endermologie (suction and kneading the skin to reduce cellulite), but fat cells that die, are processed in the subcutaneous plane underneath the skin by immune cells, called macrophages, which then pass through our lymphatic fluid circulation to our liver where they are processed and then the degraded byproducts are excreted with feces. I'm not sure that drinking a huge amount of water will help the lymphatic system circulate better. Most of my patients that have had CoolSculpting on their abdomens and flanks since I started doing CoolSculpting about seven years ago, have very good results without being told to drink copious amounts of water. Certainly, drinking enough water daily is important for good health in general, but too much water can actually negatively affect our electrolyte balance and create serious illness.
