Affirms Nicola Sorrentino, Professor of Nutritional Hygiene at the University of Pavia and scientific director of the Sensory Spa in Chianciano Terme, in his new book "Diet Water". Water is an important component of healthy diets, including weight loss diets, and is also essential for regulating body temperature and metabolism. An adequate amount of water has direct and indirect effects on the body weight regulation. Some studies, claims Sorrentino, have proven that drinking on an empty stomach increases the metabolic rate by 20-30%, that is the speed at which calories are burned to produce energy. Drink a lot of water, a practice always included in programs for weight loss, to be taken before the main meal, can help fill the stomach and reduce the appetite, but the importance of these factors is relative to another element confirmed from clinical research: thermogenesis, ie the production of body heat. This process is activated by drinking water at ambient temperature (22 °) or less, as this is turned by the body from 22 to 37 C. Most important rules to keep in mind? Drink 8-10 glasses of water per day broken down during the day before each main meal and prefer foods rich in liquids. We just have to begin to accelerate our metabolism by drinking more fresh water during the day!
