💧Water

Water is one of the four essential macronutrients, along with protein, carbohydrates, and fat.

Recommendation

Generally speaking, you should drink water when you are thirsty. This is because you may need to drink more to recover lost sweat, or less depending on your body. The populated phrase drink 8 glasses of water a day is fairly accurate. The average recommended daily water intake is 2.6 litres, which is about 10 glasses of water. "The U.S. National Academies of Sciences, Engineering, and Medicine determined that an adequate daily fluid intake is: - About 15.5 cups (3.7 liters) of fluids a day for men - About 11.5 cups (2.7 liters) of fluids a day for women" https://www.mayoclinic.org/healthy-lifestyle/nutrition-and-healthy-eating/in-depth/water/art-20044256 Keep in mind that 20% of the water you consume comes from the food you eat, so recommendations of total water intake are not the same as how much water you should drink. This is why the 3.2L recommended daily fluid intakes becomes 2.6L, or 10 glasses.
