False belief. On the contrary, you must drink as much water as possible during the day. Many people wonder how much water do I need to drink to lose weight and when I must drink water. It’s necessary to remember that in any situation, after eating sugarcane or before your usual meal – drink at least a glass of water. It will hydrate your body, help eat less, will help lose weight and stay healthy. It’s wrong to replace pure water with tea/ coffee/ juice etc. Only pure water and every day on a regular basis.
