Very interesting. I know I have gained a good 2 pounds in the last two and a half weeks. This could be due to increase in glycogen stores, but I have not been staying hydrated which is horrible and I have not gained any fat. Now I am stagnant. I need money so I can buy food and get in the gym, or I will not get much bigger.
Not staying hydrated can actually cause you to gain water weight, since your body is desperate to retain it. You can easily put on a few pounds that way, too.
Very true. Water weight fluctuates so greatly from day to day, the only way to REALLY know lean mass gains are to get regular 6-site bodyfat calipers testing (or, one of the other methods that are accurate, though usually too expensive for most people). Water definitely factors in, as I can vary in weight by up to 6 lbs. in a 24 hour period just from a change in water retention or depletion without even trying. It's precisely the reason that most people should never use a scale frequently as a gauge of progress, since water throws the whole thing off by a considerable margin and often gets misplaced blame or consideration for being fat or muscle gain/loss when it's simply water, and that most people will see such a minor change over a week's time that it probably wouldn't register at all.
