For combat athletes, the hours between the weigh-in and the fight are their own event.
You have made weight. Often that meant a hard cut, pulling water and sodium out of your body to hit a number. Now you have a limited window to put it back and walk into the cage or onto the mat rehydrated, fueled, and functional. What you do in that window matters as much as anything you did in camp.
Most athletes approach it with water and whatever is nearby. That is a mistake. Rehydration after a cut is a specific process with specific targets, and the base you build it on determines how well it works.
This is how to build that recovery bottle, and where a broth base fits.
Why Rehydration After a Cut Is Different
A weight cut is not just fluid loss. It is fluid and sodium loss together, often deliberately.
When you cut water, you also strip sodium, because sodium is what holds water in your body. That is the whole mechanism. So when you rehydrate, replacing fluid alone does not work. Drink plain water on a sodium-depleted body and much of it passes straight through, or worse, dilutes what sodium remains. You end up drinking a lot and holding little.
Effective rehydration after a cut has to replace sodium and fluid together. Sodium is what lets your body actually reabsorb and hold the water you take in. Without it, you are pouring water into a body that cannot keep it.
This is why the base matters here more than anywhere. The base of your recovery bottle needs to bring sodium, not just fluid.
The Evidence-Based Targets
Combat sports nutrition has clear guidance on the post-weigh-in window.
The International Society of Sports Nutrition's position stand on combat sports recommends aggressive rehydration immediately after weigh-in, using oral rehydration solutions at a high fluid rate combined with a substantial sodium concentration. The sodium levels recommended are well above what a standard sports drink provides. Alongside fluid and sodium, fast-absorbing carbohydrate is used to begin refueling. The overall goal is to regain a meaningful percentage of the body mass lost in the cut before competition.
A common practical benchmark is to take in more fluid than you lost, on the order of one and a quarter to one and a half times the deficit, always paired with sodium so it is retained.
The three jobs of the window, in order: replace sodium and fluid together, refuel with carbohydrate, and protect lean mass through the process. A recovery bottle should be built to serve all three.
Why Protein Belongs in the Window
Rehydration gets most of the attention after a cut. Lean mass deserves some too.
A hard weight cut is a physiological stress, and the recovery window is not only about water. Protein supports muscle repair and helps preserve lean mass through a demanding process. For an athlete who has just pushed their body through a cut and is about to compete, protecting muscle is not a side concern.
This is where a broth base does something a plain electrolyte drink cannot. Bone broth carries protein alongside its sodium and minerals. A base that brings both means your rehydration and your lean-mass support come from the same source, rather than requiring a separate step.
To be clear about the science: protein is included here for recovery and muscle preservation, not as an intra-session performance booster. That is exactly the role it earns in a recovery window.
Building the Recovery Bottle on a Broth Base
Here is the window built from the base up.
Start with a two-can BEAUNE base in a standard training bottle. That base brings 500 mg of sodium, 180 mg of potassium, and a meaningful amount of protein at once. It covers a real share of the sodium-and-fluid foundation and the lean-mass support in a single lightly sweet, slightly salty base that a nervous, post-cut stomach can handle.
Then layer the additives to hit the targets. Add sodium on top of the base's 500 mg to reach the high concentrations the post-weigh-in window calls for, because rehydration after a cut needs more sodium than any base provides alone. A build reaching 1,000 to 1,200 mg of sodium in the bottle is reasonable for this window. Add fast carbohydrate to begin refueling. Keep the fluid coming at a steady, aggressive rate through the window.

The lightly sweet, slightly salty profile is a practical advantage here too. After a cut, many athletes cannot face more sweet sports drink. Warm or cold, a lightly sweet broth base is often easier to keep down when sweetness turns the stomach. It is the same reason ultramarathoners turn to broth deep in a race, applied to the rehydration window.
A note on safety. Aggressive rehydration should be practiced in training, planned with a coach or sports dietitian, and never improvised for the first time on fight week. Extreme cuts carry real risk. This framework is about rehydrating well, not about enabling a bigger cut.
The Same Logic Applies to Hard Sessions
The weigh-in window is the extreme case, but the principle carries into everyday training.
Hard sparring, long grappling rounds, and high-output conditioning all produce heavy sweat and heavy sodium loss. The same base-and-additive logic applies. Start with a base that brings sodium, potassium, minerals, and protein, then add carbohydrate and sodium to match the session.
For a combat athlete, BEAUNE is not only a fight-week tool. It is a training-week base. The recovery bottle you build for the window is the same bottle, dialed down, that serves you after every hard session.
Key Takeaways
- The post-weigh-in window is its own event, and the base you rehydrate on determines how well it works.
- A weight cut strips sodium along with fluid, so rehydration must replace both together. Plain water alone passes through a sodium-depleted body.
- Combat sports nutrition guidance calls for aggressive fluid intake with high sodium and fast carbohydrate, aiming to regain a meaningful share of lost body mass.
- Protein belongs in the window for muscle repair and lean-mass preservation, not as a performance booster.
- A two-can BEAUNE base brings 500 mg sodium, 180 mg potassium, and meaningful protein in one lightly sweet, slightly salty base a post-cut stomach can handle. Add sodium and fast carbohydrate on top to reach window targets around 1,000 to 1,200 mg sodium.
- The same base-and-additive logic serves everyday hard sessions, not just fight week.
Where This Leaves Us
Combat athletes plan their cut in detail and often improvise the rehydration. That is backwards. The window between the scale and the fight is where a cut is either recovered from well or paid for badly.
Rehydration after a cut is a sodium-and-fluid problem with a lean-mass component layered in. The base you build it on should carry sodium and protein from the start, not just water. From there you add the sodium and carbohydrate the window demands.
Plan the rehydration like you plan the cut. Build it on a base that does more than fill the bottle.
BEAUNE Summary
The period between weigh-in and competition is a distinct performance window for combat athletes. Because a weight cut removes sodium along with fluid, effective rehydration must replace both together; plain water alone is poorly retained by a sodium-depleted body. Sports nutrition guidance for combat sports calls for aggressive fluid intake paired with high sodium concentrations and fast carbohydrate, with the goal of regaining a meaningful share of lost body mass before competing.
Protein also has a role in this window, supporting muscle repair and lean-mass preservation through the stress of a cut. A two-can BEAUNE base provides 500 mg of sodium, 180 mg of potassium, and a meaningful amount of protein in a single lightly sweet, slightly salty base that is easier to tolerate after a cut than another sweet drink. Athletes build on that base by adding the additional sodium and fast carbohydrate the window requires, commonly reaching 1,000 to 1,200 mg of sodium in the bottle. Aggressive rehydration should always be planned with a coach or sports dietitian and practiced in training rather than improvised.
