I realize that most of it was water you dolts, This is not the first time I've cut weight. However, 13 pounds is much more water than I've ever lost before and I have also never felt this good

Not to mention dropping this much is possible and not really unhealthy but you will get teh skinny fat and provbably put it back on very quickly
Conventional wisdom dictates that it is very unhealthy to lose that much weight in one week, but I trust your extensive knowledge on these things. Thought you were lifting, though...?
I expect my weight loss to slow and the days I got into the gym I didn't feel that my stregnth was suffering any negative effects nor when I ran. This week my intake has been a shade under 2000, (1967 if we are going by averages) where it's usually about 4200

I've felt really good but I figure I may have to uptick to about 2300 if I want to minimize my stregnth losses. But I do expect to lose about 25-35% off my total. Which is fine because this year school has been killing me and I've practicaly stalled in the gym anyway.

But Sarmatian nailed it: consisting for about 80% of water, Strike has basically sweat himself down to size and cut his sugar reserves a bit; and in so doing made himself a bit less edible to potential predators (levels of toxins in your blood will be up). Fat comes later, if at all.
at all? I know plenty of people who drop and gain fat all the time.....

During a decent intensity, 45 minute weight training you'll lose 400-500 calories. Half an hour of jogging, again depending on the intensity and terrain, 250-350. Calories are easily lost, even by walking. The only way you'd need less than 2000 calories a day is if you're a type of guy who gets up in the morning, walks to his car, drives himself to work, sits all day, drives himself back home and sits in front of TV, goes to sleep and does it all over again, but even with that lifestyle, I'd say 1000 calories is too little.
I know guys who can eat 2000 and stay at 225 lbs and I know guys who have to 5000 just to gain a miniscule amount of weight, caleroic intake is all personal
