Although you might overlook water, it serves many important purposes. Water helps carry other nutrients throughout the body and helps transport waste products out of the body. It functions as a “joint lubricant” and a “cell shock absorber.” It enables numerous chemical reactions to take place and helps regulate your body temperature. When it comes down to weight loss, water plays a notably important role. As fat breaks down, the body requires increased fluids to help eliminate the resulting wastes. Water also aids in controlling bowel regularity. Plus, drinking more fluids can help you feel full.
