Quick weight loss using dehydration and food restriction in the week before a match is the tradition in wrestling to “make weight.” Whether by a drastic reduction in calorie (energy) intake or by dehydration, losing weight rapidly can have negative outcomes that hurt performance by:

Disturbing mood and impairing ability to think and focus mentally.

Reducing blood sugar and disrupting certain hormones—these changes reduce energy and may lead to overtraining.

Decreasing blood volume and raising body temperature, both of which promote fatigue.

Decreasing endurance, particularly in practice and late in competitive matches.

In extreme circumstances, causing kidney failure and even death.
Weight Loss Goals

Most weight classification systems in state high-school associations are now designed to promote safe, slow rates of weight loss during the season. The systems also allow wrestlers to start competition at higher weight classes as they slowly work down to their minimal weights. Wrestlers are encouraged to track the weight lost as fat every week by weighing in at the beginning of the week in a well-hydrated state.

Loss of mostly fat weight (not water weight) in the weeks before a match should be no more than about 2 lbs or 1 kg per week. This can best be achieved by consuming a diet containing about 500–1000 kcal less energy per day than typical for the individual wrestler. There should be plenty of fiber in the diet until the last few days before a match. In addition to gradually reducing calories in the diet, extra aerobic exercise will help lower fat weight. This slow rate of weight reduction is ideal for minimizing the loss of muscle protein and maintaining hydration and energy for tough practices.

Some wrestlers may choose to undergo modest dehydration to assure making the desired weight class for competition. Those athletes should limit any weight loss by dehydration to not more than 2% of body weight. (This is 2% of body weight at the beginning of the week of training and should only be tolerated for a short period, e.g., overnight before a match.) Most of this weight could conceivably be regained by drinking fluids between weigh-in and competition. However, it is a challenge for wrestlers who lose weight quickly to have rapid and complete recovery after weigh-in to re-establish normal standards of body functions, metabolism, and performance. Any attempt to lose 2% of body weight or more day after day for a total of 6 to 10% dehydration in the week before a match will dramatically increase the risk for heat illness and the other negative outcomes listed above.

Recovery Diet

The goals for the recovery period after weigh-in are to restore blood glucose and muscle carbohydrate levels and to replenish body water as much as possible. These goals can best be achieved nutritionally by focusing on:

Fluid consumption—to restore blood volume

Beverage volume—The goal is to consume 150% of the weight lost by dehydration. When there is only a short period of time for drinking (e.g., only a few hours), it is essential that the beverage contains sodium and other electrolytes to help the body rehydrate quickly.

Schedule—Wrestlers should begin by consuming the maximum volume of fluid they can tolerate and then drinking additional amounts every 15 minutes.

Flavor—Flavored drinks can increase the desire to continue drinking.

Temperature—Cool drinks taste better and encourage drinking, but if a wrestler experiences chills, beverages should be maintained at room temperature.
Electrolyte intake—to maintain thirst and restore blood volume

Water alone is inadequate for complete rehydration. Consumption of plain water will reduce thirst and cause more fluid to be lost as urine.

Use carbohydrate-electrolyte sports drinks, especially those with extra sodium, and add salty foods to the diet: Although high-sodium beverages can be unpalatable, some new sports drinks have been developed that overcome this problem. Salty foods that are quickly digested should be consumed during the recovery period.
Carbohydrates—to provide energy for muscle and brain function

Emphasize easily-digested carbohydrate-rich foods such as pretzels and sports bars and, especially, carbohydrate-rich liquids that empty rapidly from the stomach to provide the energy need for training and competition.
Precautions:


For the snacks eaten immediately following the weigh-in and during tournament competition, minimize fullness by avoiding high-fiber or high-fat foods that are emptied slowly from the stomach, and do not drink carbonated beverages that contribute to bloating.
Stop food and fluid consumption about 30 min before the match so the stomach has a chance to empty.

Example:

A wrestler loses 1 kg (2.2 lbs) by dehydrating the day before a match. Following weigh-in, the wrestler should consume:

1.5 L (~51 oz) of high-electrolyte beverage (e.g., Gatorade Endurance Hydration Formula or traditional sports drink with added ½ tsp salt): Drink 30 oz (900 ml) to start and 7 oz (210 ml) every 15 minutes through the first hour.
Plus

One of the following (or equivalent):
1 or 2 sports bars or fig bars

3 oz (90 g) pretzels

1 slice of bread with thin peanut butter or slice of cheese

8 oz (240 ml) chocolate milk or yogurt

1 can liquid meal replacement (e.g., Gatorade Nutrition Shake)
