Supposedly, older people cannot detect thirst easily. That being said, I check urine color to figure out if I'm getting dehydrated. Dark yellow means start drinking - you're getting dehyrated. Fatigue also seems to be an indicator.
I currently drink about 3 liters a day, but I'm about to up that to 4 (that's more than a gallon of water..yikes!) based on a calculation I read somewhere.
I'm going to start tracking it. I have a 1 liter bottle in my office. I used to fill it up whenever I happen to be going towards the water cooler, but now I am going to try to drink it until it is empty, log it in MPF, and then refill. I will try to drink 3 liters while at work and then a liter at home. Plus extra when I work out. We'll see if this helps at all!
Water is our best friend in this battle with weight! I know that you need to drink not less than 2 litres per day, better 3. I have never counted how much i drink water because i drink really a lot)) I guess more than 5 litres per day. I can not say that it helps a lot with losing weight, but i think maybe i drink too much??
I drink about 4 liters a day. This does not include water at restaurants or when I am working out with a bottle. I have a 2 liter bottle that I fill in the morning and make sure that I finish before lunch. Fill again at lunch and work on it the rest of the day. I just make sure I don't drink past 9:00 pm or I am up at night for the bathroom. Bathroom trips are frequent at first, then get less the more you stay hydrated for me.
I know for sure that water makes a difference. The water in my city was contaminated for over a week and bottled water was a hot commodity. So I had to drink a lot more juices and soda than I was used to. I felt like crap. Bloated, irritable. I feel WAY better just even drinking water from the tap than I do with anything else.
Currently jumping back on the wagon! Not staying down!
Here is an article I've kept and read every time I find myself not drinking enough water. It says that the main job of the liver is to burn fat. The main job of the kidneys is to filter toxins, but it needs plenty of water to do it's job efficiently. If the liver has to help the kidneys, it can't concertrate on it's job of burning fat. I always lose faster if I keep up my water intake. By the time you feel thirsty you are already dehydrated.
