Dehydration increases body fat! Every thing we eat our body tries to convert to glucose, it is the only fuel for our brain. Water contributes to energy storage along with glycogen. The more dehydrated you are, the more glucose remains in your bloodstream and will be stored as FAT. When your body is dehydrated it pulls water from the cells to hydrate the body. This includes your FAT cells. When your Fat cells are dehydrated your body will not use that fat for energy, instead it will use whatever fuel is readily available in the body.
So if you put in hours at the gym and aren't seeing much of a change it could be that your actually really dehydrated and no amount of activity will allow your body to use its excess fat for energy.
Not only that, but it is our kidneys job to filter toxins, waste, water and salt out of the blood stream and our livers duty to metabolize stored fat into energy. The liver however, CAN NOT WORK if the kidneys are not functioning properly. The liver must work harder and thus, metabolizes less fat.
It is recommended to drink 8 glasses of water a day. This is not enough water at all. We need water to function properly and if you're not peeing clearly and guzzlin the stuff throughout the day than you need to be drinking more.
