|"Where bro- and pro.science meet!" could have been the motto of the Indian researchers who probed the "drink water to lose weight myth" in their latest study.|
Apropos housewifes! I can't tell for sure, but it's certainly not unlikely that overweight female subjects of a recent study (Vij. 2014) from the Seth Gordhandas Sunderdas Medical College and King Edward Memorial Hospital in Mumbai were actually housewifes - probably not.
In the end, the occupation state of these ladies, whose mean body weight at the beginning of the study was 65.86kg (BMI 26.7) doesn't really matter, anyway.
What does matter, though, is that the 50 young ladies (age 19-29.9y) were - in European or US terms - comparably lean, when they were told to increase their water intake by 1.5 L, over and above their usual daily water intake. To achieve this, 500 mL of water was consumed 30 min before breakfast, lunch, and dinner.
Water warning: It may sound stupid, but too much of a good thing can easily be as bad as too little. This is not different for water! Adding 1.5l to a baseline water intake of <2l certainly isn't a problem. Drinking 15l per day to lose weight, on the other hand, would have you lose much more than body fat - in the long run, possibly even your life.Why that's important? Well, if you weigh "only" ~130lbs and still manage to lose 2.8lbs in 8 weeks, that's quite significant considering the fact that the only thing you'd have to do to achieve that is drink 500ml of plain water before each meal, right?
