What is this stuff basically for? And besides it containing calories. Does this stuff contain carbohydrates? I need to know a more in depth description of this stuff. As far as I know...it holds on to water and that it will make the person looked more leaner? Am I right?

I'm currently on fat burners. And I sweat a lot! Not only that but I work out very hard and I sweat from training. I also live here in Miami and go to the beach quite often and sweat a lot there too. And where I work at...it is very hot and I sweat like a pig all day long.

Even though i do drink up to 2 gallons of water a day. I still look flat because of losing so much water. The fact that this hydrates really good made me interested in it. But I am also currently on a low carb diet. Trying to lose a lot of BF for the summer. If I take this stuff.....will I be hindering my BF lose? By adding extra carbs?
