The One Mistake That Wrecks a Water Cut
A few weeks before Riddlestruck, I talked two of my athletes into being guinea pigs. Bobby Hicks and Audrey Carlson agreed to run a 12 day water cut protocol with me; I ran it alongside them out of solidarity, even though I had no weight class to chase. I just don't ask people to suffer through something I haven't suffered through myself.
We logged everything. Daily weights, carbs, sodium, steps, training notes, all of it in one shared spreadsheet. Three different humans, three different sizes, three different weight classes. And the same response showed up across all of us. That's the part worth writing down.
Here is the single thing I want you to take from it. A water cut is not "stop drinking and dry yourself out the day before weigh-in." That's the version most people picture, and it's exactly backwards. A real water cut is a hormonal trick. You get it wrong by pulling water too early. Get the timing right and your body does the work for you. Get it wrong and you fight your own physiology the whole way down.
What's actually happening in your body
Your kidneys don't decide how much water to dump based on how thirsty you feel. They take orders from hormones, mainly ADH (antidiuretic hormone) and aldosterone. These are your "hold onto water" signals. When your body senses it's running low, those signals climb and you retain everything you can.
So the first phase isn't restriction. It's the opposite. You water load. For a week-plus you drink absurd volumes, two to three gallons a day for a bigger person. Audrey called it the piss fest, and that's accurate; you'll be up six times a night. It feels stupid. You feel waterlogged. Your stomach is sloshing during long cycle. But there's a point to it.
When that much water keeps flooding in, your body decides it doesn't need to hold any of it. It turns those "retain water" hormones DOWN. You've convinced your system that water is abundant and safe, so it stops hoarding. You're essentially turning on the faucet, sticking your head under it, and teaching your body to leave the drain open.
Here's the kicker most people miss. Even while you're drinking gallons, you still lose a couple pounds that first week, because your body has already stopped clinging to fluid.
Why you pull water LAST, not first
This is the whole game, so I'll say it plainly. The water excretion phase comes as close to weigh-in as possible. You stay hydrated as long as you possibly can.
Why? Because once you turn the faucet off, your body keeps excreting. The hormones are still suppressed. The drain is still open. So you cut intake at the very end, and your body keeps flushing fluid out on momentum, because it still believes water is plentiful. That's when you do your sweat work; a sauna, a hot bath, a hard session in the heat. I lost 11 pounds in a single 90 minute window of long cycle plus a hot bath, because my body was primed to let water go.
Now flip it. Pull water too early and ADH and aldosterone shoot back UP, sometimes higher than where they started. Your body panics. It clamps down and guards every ounce it has. Then you climb into the sauna and wonder why you can't sweat, why the scale won't move, why you feel like garbage with nothing to show for it.
That is the number one mistake I see people make with water cuts. They cut water too early, spook their hormones, and then can't sweat when it counts. The mechanism that should be working for you is now working against you. Stay hydrated as long as you can. Pull water last.
The honest part
Now the asterisk, because I won't sell you a fantasy. This is water, not fat. Every pound came right back when we refed. Bobby walked around at 207, cut to 194.6, and was back at 201.2 a day after refeeding. That's the system working correctly; you flush water out, you put it right back in.
So a water cut is never your weight-loss plan. If you need to drop real size, you do that earlier, over a full prep, through sustainable nutrition, so you arrive close to your class before any of this starts. The cut is a tool for the last few pounds when you're already within striking distance, and the point in our sport is rank: a lower weight class needs fewer reps for the same rank. Drop a class, owe the platform a few less reps.
And it costs you. Cutting carbs tanked our training; 20kg bells suddenly felt like 28s. Cutting sodium was the part everybody hated most. Audrey nailed her goal of five pounds exactly and still said she wouldn't do it again for five pounds, because the mental load before a comp wasn't worth it to her. That's a real answer. If you're not already an elite athlete bumping against rank by a rep or two, this might be more suffering than it buys you. You can also run a lighter version: water load, then water excretion, and skip the carb and sodium phases entirely; you still get the hormonal response without trashing your performance.
One scope note, because this is physiology and not a prescription. This is a general principle, not a plan for your body; cutting water and electrolytes can get dangerous fast, so do it under supervision, check with your doctor first, and work with a coach who's monitoring you.
The piece I'd hand anyone, cut or no cut: most people walking around are simply underhydrated, and the day you start drinking enough, you sleep better, you train better, you feel better. That part isn't a trick. That one's just true.

If you're chasing a rank and want a coach who'll run the experiment alongside you instead of just handing you a protocol, come work with me. I've never turned anyone away over money, and I'd rather help you do the hard things the smart way.
