Theoretically, when you drink ice water, your body temperature will drop. In order to warm up, the body needs to burn more fat. But the body actually consumes much less calories during the warm-up process. At present, this is only a hypothesis, and there is no effective and rigorous scientific research to prove it. And drinking ice water can cause abdominal pain or diarrhea. Therefore, drinking more water and properly controlling food intake is much more effective and healthy than drinking cold water blindly.
