Science has found out when and how many glasses of water you should drink a day to effectively lose weight
Generally recommended maintain good hydration in normal everyday life, and especially in the process of almost any disease. In addition, when trying to lose weight, the emphasis is also usually on hydration, since water has a certain satiating potential, and adding it to a meal before or at the same time as it can increase satiety and slow down gastric emptying.
Now a team of researchers from the University of California, San Francisco, has systematically analyzed what scientific basis exists for this phenomenon. water consumption and weight loss references, and they also looked at other possible benefits of drinking water: preventing kidney stones, preventing migraines, reducing the risk of developing urinary tract infections, or reducing high blood pressure. Their findings were recently published in the journal PIT.
As Benjamin Breuer, lead author of the study and president of the department of urology at the University of California, San Francisco, explains: “For such a widespread and simple intervention The evidence has not been as clear and its benefits have not been as well established.so we wanted to take a closer look. The amount of rigorous research has been limited, but statistically significant benefits have been observed in some specific areas. To our knowledge, this is the first study to evaluate the impact of water intake on overall clinical outcomes.”
In this case, this systematic review took into account 18 controlled and randomized clinical trials and did not find as many benefits as usually advertised, although proper hydration is not without evidence: most of the evidence presence suggests that Drinking water can prevent kidney stones and help you lose weight.
Some of the studies reviewed showed that Drinking about six glasses of water a day will help you lose weightalthough one study that included teenagers concluded that drinking just over eight glasses of water a day would have no effect. However, the authors suggest that we should drink water before meals, given that it is a simple and cheap intervention with huge benefits, especially given the rising prevalence of obesity.
Other studies have shown that drinking water may help. prevent migraines, better control diabetes and high blood pressure, and prevent urinary tract infections: Adults who suffered from recurring headaches felt better after three months of increasing their regular water intake.
In turn, patients diagnosed diabetes achieve improved blood glucose control by drinking at least four glasses of extra water per day.
Regarding urinary tract infectionsDrinking six extra glasses of water per day would prove to be an effective, simple and low-cost intervention for reducing the recurrence of these infections in women, reducing both the number of infections and the time interval between infections. Likewise, drinking water can improve cases of low blood pressure or hypotension.
The authors, led by Breuer, they conclude: “We knew that dehydration was harmful, especially for patients with kidney stones or urinary tract infections. On the other hand, if you suffer from frequent urination, drinking less water can sometimes be helpful. a universal approach to water consumption.”
So, while evidence suggests you should drink at least eight glasses of water a day, “Additional” dosage will vary depending on the pathology, as well as between individuals.: Not everyone needs the same amount of fluid, and this can greatly depend on the level of sweating or physical activity; And of course, you need to consider your normal urination rate so you don’t create even more problems by trying to hydrate in an unusual way.
