According to the U.S. National Academies Of Sciences, engineering, and medicine they recommend that women drink 11.5 cups of water per day. And they recommend for men to drink 15.5 cups of water per day.
The amount of water that each person depends on the following:
- How physically active you are will always predicate how much water you drink. If you are very active, then your body will need more water.
- Your environment will dictate how much water your body needs. If you live in hot environments your body will crave more water.
- If you are pregnant or breastfeeding your body will need to drink extra water to say hydrated.
- If you drink a lot of coffee or caffeinated beverages, you will need to be more dehydrated. And you will need more water than the average person.
- If you live in an area where the temperature is always hot, then your body will need more water to stay hydrated because you are perspiring more.
Drinking water will help you lose weight because it makes you more fuller especially if you are drinking up to 8 glasses of water a day. There was a study that showed that drinking more water was associated with a decrease in bodyweight and body composition scores.
And there has also been studies that have shown that chronic dehydration is associated with obesity, diabetes, cancer, and cardiovascular disease. The glass of water should be 8-ounce glasses of water.
There was another study that showed that drinking water about a half hour before meals can reduce the number of calories you end up consuming. And I can see that because the body may mistake water with fulfilling your hunger as opposed to food.
And lastly a study showed that people who drank 17 ounces of water before each meal lost 44% more weight over 12 weeks compared to those who didn’t.
These studies give great insight and data that drinking lots of water especially before you eat can suppress your appetite.
