Of course you are not going to lose all 5lbs of fat, I mean u r going to lose some water weight too. Even if you do lose water weight you will feel less bloated and water is good for your skin, and other imoportant organs too so even if your goal is not to lose weight you should still try to drink tons of water b/c your body is losing water every sec. of the day and you need to replenish it n e way. Drinking water to get clearer skin and lose weight?? What a bargain...
