9 Science-Based Ways for Athletes to Lose Weight	The fundamental principle remains the same regardless of the specific program followed—eat less, exercise more, or do both. As a rule of thumb, 1 pound 0. Mathematically, if a person reduced food intake and increased exercise by a combined kcal daily, then in seven days' time he or she would lose 1 pound of body fat. Such estimates are correct, but a kcal deficit is very difficult to achieve for most sedentary people, many recreational athletes, and many small-bodied athletes whose caloric intake is relatively low. Losing substantial amounts of body fat takes time and sustained motivation. There is no shortage of advice on the subject of weight loss, but when applied to athletes there are some important issues to consider. The most important are timing, degree of calorie restriction, composition of the diet, and avoiding strategies that will undermine training, recovery, and performance. Athletes need to understand the following:. Unfortunately, many athletes fall prey to the quick fixes and rapid weight loss programs that are so heavily advertised. These programs generally suggest severe calorie restriction so weight loss is rapid. However, it is recommended that athletes consume no less than 30 kcal per kilogram of body weight daily. For example, a pound 70 kg athlete who wants to lose body fat should not typically consume less than 2, kcal daily. This caloric level is above resting metabolic rate and is not considered a starvation-type diet. Caloric restriction below this level will typically not provide enough of the carbohydrate, protein, and fat needed to maintain training or conditioning. A tool that can help athletes create a personalized fat loss plan is the daily energy intake and expenditure estimates described earlier in this chapter. A good rule of thumb is to create a daily calorie deficit of about kcal. For example, an athlete may look at his usual food intake and activity level and find that he could realistically decrease his food intake by kcal daily and increase his exercise by kcal daily. An increased torso-to-leg ratio also results in increased BMI. In adolescents, increased weight gain and increased height velocity during puberty may not coincide, resulting in temporary elevation or depression of BMI. Although there are normative data for body fat percentage, there are no established recommendations regarding body composition in children and adolescents. These minimums are well under the fifth percentile for body fat observed in the general adolescent population. Rather than suggesting a specific percentage of body fat for an individual athlete, a range of values that is realistic and appropriate should be recommended. Physicians who care for young athletes are encouraged to have an understanding of healthy and unhealthy weight-control methods;. Health supervision visits for young athletes generally include history-taking to ascertain diet and physical activity patterns. When discussing diet and exercise, physicians can encourage parents of young athletes to place nutritional needs for growth and development above athletic considerations. Acute weight loss through dehydration and the use of potentially harmful medications and supplements for weight control should be strongly discouraged;. Physicians should counsel young athletes who express a desire to gain or lose weight to avoid weight-control methods that may have adverse health effects, such as acute weight loss through dehydration and the use of potentially harmful medications and supplements. Many of these methods may have a negative effect on performance as well;. Some states require a specific form for sports preparticipation examinations. For physicians in states without a specific requirement, the AAP Preparticipation Physical Examination monograph contains a standardized history-taking form that may be helpful for screening athletes. This form is also available on the AAP Web site and includes questions designed to screen for disordered eating and menstrual irregularities. Physicians are encouraged to engage the services of RDNs familiar with athletes to help with complex weight-control issues, if these providers are available in their communities. Monitoring athletes with weight-control issues every 1 to 3 months can aid the physician in detecting excessive weight loss;. There are no established recommendations for body fat percentages in adolescent athletes. Rather than suggesting a specific percentage of body fat for an individual athlete, a range of values that is realistic and appropriate should be recommended;. Physicians should counsel young athletes that weight gain or weight loss regimens should be initiated early enough to permit gradual weight change before a sport season. Slow weight gain, in combination with strength training, will decrease gain of body fat. Slow weight loss in the athlete with excess body fat will decrease loss of muscle mass. A well-balanced diet is recommended for all athletes. Once the desired weight is obtained, the athlete should attempt to maintain a constant weight; and. When opportunities for community education arise, pediatricians should collaborate with coaches and certified athletic trainers to encourage healthy eating and exercise habits.

Weight loss in combat sports: physiological, psychological and performance effects	There is perhaps no other topic in nutrition that creates such debate and opinion as weight loss, particularly body fat loss. The rules of some sports also dictate body weight categories and aesthetic requirements as part of the selection or judging process. This can create enormous confusion and has the potential to undo all the hard training that athletes put in if they take the wrong approach or look for quick fixes. The goal of most if not all weight loss plans is to create a negative energy balance where more energy is used than consumed by the body. There are many ways to achieve a negative energy balance and often diets promote cutting out entire food groups particularly carbohydrates and dairy foods to do this. While this might result in some quick weight loss initially, unfortunately, this loss is usually short term and unsustainable and weight lost is quickly regained. Still, consume no less than 1. Cutting out added sugars is the healthiest way to reduce your total carb intake. To do so, check labels and minimize foods that contain added sugars like glucose, sucrose, and fructose. Also, avoid cane juice, dextrin, maltodextrin, barley malt, caramel, fruit juice concentrate, fruit juice crystals, or other syrups. Instead, increase your intake of vegetables high in fiber. These will help keep you fuller for longer, making you feel more satisfied 12 , 13 , SUMMARY Eating less sugar and more fiber can help you reach your body fat goals. Athletes should aim to eat no less than 1. Protein aids fat loss in several ways. To begin with, high-protein diets increase feelings of fullness and the number of calories burned during digestion. They also help prevent muscle loss during periods of weight loss, including in well-trained athletes 5 , In fact, several studies show that eating 2—3 times more protein per day can help athletes retain more muscle while losing fat 9 , 16 , Therefore, athletes restricting their calories to lose weight should eat 0. Consuming more than these amounts can displace other important nutrients, such as carbs, from your diet. This can limit your ability to train and maintain good sports performance 2 , 3 , 9 , SUMMARY Higher protein intakes help limit muscle loss while your weight is dropping. Athletes should aim to consume 0. In addition to eating more protein, athletes can benefit from spreading their intake throughout the day In fact, 20—30 grams of protein per meal seems sufficient to stimulate muscles to produce protein for the following 2—3 hours. Interestingly, studies in athletes show that spreading 80 grams of protein over 4 meals stimulates muscle protein production more than splitting it over 2 larger meals or 8 smaller ones 22 , Eating a snack with 40 grams of protein immediately before bedtime can also improve recovery from training and increase muscle protein synthesis during the night SUMMARY Eating 20—30 grams of protein every 3 hours, including right before bed, may help maintain muscle mass during weight loss. Eating the right foods after training or competing is vital, especially when trying to lose body fat. Proper refueling is especially important for days with two training sessions or when you have fewer than eight hours of recovery time between workouts and events 2. Athletes following carb-restricted diets should aim to consume between 0. Adding 20—25 grams of protein can further speed up recovery and promote protein production in your muscles 2. SUMMARY Consuming a good amount of carbs and protein immediately after training can help maintain your sports performance during weight loss. Individuals attempting to lose weight are often at risk of losing some muscle in addition to fat. Athletes are no exception. Some muscle loss can be prevented by eating a sufficient amount of protein, avoiding crash diets, and lifting weights 3. Research shows that both protein intake and strength-training exercises stimulate muscle protein synthesis. Nevertheless, make sure to speak to your coach before adding any extra workouts to your schedule. This will reduce your risk of overtraining or injuries. SUMMARY Strength-training exercises can help prevent the muscle loss often experienced during a period of weight loss. Researchers believe these adaptations can persist for some time after you bump up your calorie intake and cause you to quickly regain the lost fat 5. This may help restore your hormone levels and metabolism better, minimizing the weight regain 5. SUMMARY Increasing your calorie intake gradually after a period of weight loss may help minimize weight regain. Although weight loss is a widely researched topic, the number of studies performed on athletes is limited. Nevertheless, many of the strategies scientifically proven to help non-athletes lose body fat may also benefit athletes. Thus, you can try some of the following:. SUMMARY Stress, sleep, hydration, and alcohol all affect weight loss. Eating slowly, controlling portion sizes, and sleeping well can all help you lose weight. Those who want to reduce their body fat levels should aim to do so during the off-season. Keep in mind that lower body fat is not always better. Athletes should discuss any weight loss goals or strategies with their coach or sports dietitian.

How Should Athletes Diet? - Sports Nutrition Tips For Athletes But Weight management for athletes it possible Weight management for athletes an fod to lose weight without sacrificing performance or risking bodily breakdown? Weight manwgement can have both positive and negative effects on sports performance —a lot of which athleyes on Ribose and DNA replication approach. When done right, Weight management for athletes shows managment weight loss can lead to improvements in both strength and endurance, whereas rapid or excessive weight loss can have the opposite effect [ 1. From a biological perspective, weight loss requires a deficit of calories. Carbohydrates, protein, and fat are the three macronutrients that provide your body with the calories it needs to function and perform its best. In turn, your body relies on its carbohydrate, protein, and fat stores for fuel. The body stores carbohydrates as glycogen in the muscles and liver and fat in adipose fat tissue.

Weight management for athletes -

Considering these potential benefits and the higher protein needs of athletes, experts recommend a protein intake of 1. In addition to eating more quality protein, your intake should be spaced throughout the day. You can meet your protein needs through dietary sources or with protein powder, like Elo Smart Protein.

Have a meal hours before a tough workout to bolster your glycogen stores. Consider having a light snack with both carbs and protein minutes before longer, or more intense workouts to increase energy and protein availability.

Staying well hydrated throughout the day—particularly before, during, and right after exercising—will help with weight loss while also helping you feel and perform your best [ 1.

Elo Smart Protein was designed with post-workout nutrition in mind. Each blend is hand-mixed just for you and is optimized to deliver the right amount of protein and key amino acids after each workout to help you recover faster while supporting healthy weight loss. Learn more about Smart Protein, including how we build your blend and why it can help you meet your nutrition and recovery goals here.

In addition to upping your protein, make sure to add regular strength training sessions to your routine. Strength training is more effective for building muscle than cardio and also produces an afterburn effect technically known as excess post-exercise oxygen consumption, or EPOC that can increase your calorie deficit and promote greater weight loss over time [ Evidence shows that strength training, when paired with adequate protein intake, can preserve lean body mass and minimize reductions in metabolic rate during weight loss [7].

Make sure to incorporate at least strength training sessions into your training regimen to build strength, reduce the risk of injury, and maintain lean body mass [9].

Losing weight can make training feel more difficult and sometimes hinder performance, especially if it involves loss of lean muscle mass.

For the casual athlete looking to lose a few pounds, you may slim down just by exercising more regularly or training for an upcoming race.

For the more competitive athlete, dieting during peak training season can have some serious consequences. Research shows calorie restriction during training can not only impede performance but lead to significant losses of lean muscle mass, physical and psychological symptoms of overtraining, and illness [6].

For this reason, serious athletes should focus on eating for performance during peak training periods to maximize training effects and to maintain body weight and health. Serious weight loss is best saved for the off-season when energy and performance demands are lower [ 5.

Rapid weight loss can have several negative effects on hormones, metabolism, and body composition. While you may hit your weight loss goals faster, large caloric deficits come at a cost, including greater losses of lean body mass and compromised athletic performance and recovery [7].

As you get leaner, slower rates of weight loss can better preserve lean body mass, which is crucial to performance [2]. Crash diets are a recipe for disaster, but evidence suggests time-restricted feeding TRF , a form of intermittent fasting, may be better for weight loss than daily calorie restriction.

Studies show intermittent fasting diets, particularly TRF, perform equally to or better than daily calorie restriction for improving body composition [2].

Unlike other types of intermittent fasting that involve calorie restriction, time-restricted feeding allows you to eat as much as you want during that hour window.

Many find time-restricted feeding less restrictive and easier to stick with since all foods are fair game, and a significant portion of the fasting window happens while you sleep. Start with a hour overnight fast and increase as tolerated to hours. Ideally, do your workout in the middle of your eating window, so you have some fuel in the tank and can adequately refuel after.

If you have diabetes or low blood sugar, chat with your doctor or dietitian about trying TRF safely. Modestly reducing calorie intake while maintaining a high-carbohydrate, high-protein diet weight during peak training periods [ 1. Consuming 1. Staying well hydrated throughout the day and before, during, and after training.

Prioritizing pre-and post-workout nutrition specifically carbohydrates, protein, and fluid intake to optimize performance and recovery. Losing weight does affect endurance.

Research shows aerobic endurance capacity decreases after rapid weight loss but might increase after gradual weight loss [ 1. Losing weight affects strength. Studies performed in national level competitions have produced conflicting data. In a study by Horswill et al.

Assuming that the body mass recovered after weigh-in is associated with body mass reduced before the weigh-in, the authors concluded that the amount of weight lost and, consequently, the amount of weight regained after the weigh-in has no effect on competitive success.

In contrast, Alderman et al. Some authors [ 8 ] argue that a successful career is probably built in a single weight class. Despite the paucity of evidence that indicates an association between rapid weight loss and competitive success [ 5 , 14 ], it must be noted that it is possible to achieve success in combat sports while competing in multiple weight classes.

Some prime examples are the successful athletes who moved to heavier weight classes and still performed at the highest level e. While studies are scarce and inconclusive, the impact of RWL on competitive success remains elusive, especially when considered the great number of variables defining wins and losses.

Despite conflicting evidence, most studies indicate that weight loss decreases both aerobic and anaerobic performance. While aerobic performance impairments have been attributed to dehydration, decreased plasma volume, increased heart rate, hydroelectrolytic disturbances, impaired thermoregulation and muscle glycogen depletion [ 30 ], decreased anaerobic performance is mainly related to reduced buffering capacity, glycogen depletion and hydroelectrolytic disturbances [ 30 , 35 ].

Maximal strength seems to not be acutely affected by RWL [ 36 — 38 ], although chronic weight cycling has a negative impact on strength gain during a season [ 39 ]. It is important to highlight that the decrements on anaerobic performance are generally observed when athletes have no opportunity to refeed and rehydrate after weigh-in [ 27 , 38 , 40 , 41 ].

However, in the most combat sports competitions, weigh-ins are followed by a period of time during which athletes may have the chance to recover from the weight loss. Although this period may vary from a few hours to more than one day, it is very likely that within 3—4 hours, athletes are able to recover their anaerobic performance to pre-weight loss values [ 9 ].

Therefore, when followed by a relatively short recovery period, RWL will probably have minimal or no impact on anaerobic performance. Although this seems to be true for athletes who are experienced weight cyclers, athletes with no experience in reducing weight might be negatively affected by weight loss [ 42 , 43 ].

It suggests that weight cycling may lead athletes to develop physiological adaptations that help them to preserve performance after weight loss. However, to date there is no direct evidence supporting these hypothesis and further studies are needed to confirm or refute them. Some epidemiological studies have associated RWL with increase risk for injuries [ 44 ].

Oöpik et al. Due to the possible adverse effects of RWL, there are rare cases of death related to this practice. In , just three months before Atlanta Olympic Games, Chung Se-hoon 22 years, 74 kg , considered the probable gold medal winner in the 65 kg weight category in judo, was found dead in a sauna.

The c ausa mortis was a heart attack. One year later, three collegiate wrestlers died due to hyperthermia and dehydration associated with intentional RWL [ 47 ].

During the Sydney Olympics, Debbie Allan from Great Britain was disqualified during the weigh-in because the scale used by her was not calibrated due to an alleged scale sabotage [ 48 ]. The problem seems also to affect children. Those extreme cases, together with the very high prevalence of RWL achieved by aggressive methods, illustrate quite clearly that the scenario is disturbing, the problem may be more serious than many people involved with the sport may think and that more attention to this problem should indeed be given.

No athlete should be encouraged to cut weight quickly in order to compete in a lighter weight class. Gradual weight loss i. Athletes should aim to maximize body fat loss and minimize muscle wasting and dehydration when adjusting weight.

During the weight loss period, strength training and BCAA supplementation may help preserve muscle mass. Athletes should not undergo low-carbohydrate diets in order to make weight as they seem to be more detrimental to physical performance [ 41 ].

If an athlete will have less than 3 hours to recovery after the weigh-in, RWL, dehydration and restricted carbohydrate ingestion should be avoided. During the recovery period after weigh-in, athletes are encouraged to consume high amounts of carbohydrates, fluids and electrolytes.

Creatine supplementation may also be of use if the athlete will recover for a long period after weighing-in. Control strategies to avoid RWL practices can be divided in two areas: 1 coach and athlete educational programs; 2 management procedures to control or discourage RWL. According to Burke and Cox [ 3 ], athletes and coaches should receive information about: caloric balance; how to prepare each food portion; how to avoid increase weight especially fat after the competition; how to prepare food using low fat ingredients; how to prepare snacks with low caloric content using fruits and vegetables; how to avoid combating stress through excessive food intake; how to avoid gastronomic novelties during high-level competitions abroad or when inside the Olympic village; the importance of avoiding fast-food restaurants while travelling; how to increase satiety using low glycemic index foods; how to avoid excessive food and alcohol intake during celebrations; how to keep a diet diary and how to identify the main difficulties to maintain adequate nutrition.

Additionally, the recommendations done by Horswill [ 20 ] concerning body mass control during the season are important sources of information. This author suggests specific goals for each periodization phase. Management procedures have been used in wrestling [ 53 ] and proposed for judo [ 8 ] to avoid weight loss among athletes.

The following recommendations were first drafted in [ 54 ] and reinforced in by the American College of Sports Medicine [ 14 ]. They are currently in use in most scholastic wrestling competitions in United States as a part of a program aiming at controlling the weight management issue among wrestlers.

This program has been shown effective in attenuating the aggressive patterns of rapid weight loss and discouraging athletes from losing weight irresponsibly [ 20 ]. Therefore, these recommendations should be implemented by other combat sports organizations in order to avoid widespread weight loss among combat athletes [ 8 ]:.

Physicians who care for young athletes are encouraged to have an understanding of healthy and unhealthy weight-control methods; Health supervision visits for young athletes generally include history-taking to ascertain diet and physical activity patterns.

Acute weight loss through dehydration and the use of potentially harmful medications and supplements for weight control should be strongly discouraged; Physicians should counsel young athletes who express a desire to gain or lose weight to avoid weight-control methods that may have adverse health effects, such as acute weight loss through dehydration and the use of potentially harmful medications and supplements.

Many of these methods may have a negative effect on performance as well; Some states require a specific form for sports preparticipation examinations. Monitoring athletes with weight-control issues every 1 to 3 months can aid the physician in detecting excessive weight loss; There are no established recommendations for body fat percentages in adolescent athletes.

Rather than suggesting a specific percentage of body fat for an individual athlete, a range of values that is realistic and appropriate should be recommended; Physicians should counsel young athletes that weight gain or weight loss regimens should be initiated early enough to permit gradual weight change before a sport season.

Once the desired weight is obtained, the athlete should attempt to maintain a constant weight; and When opportunities for community education arise, pediatricians should collaborate with coaches and certified athletic trainers to encourage healthy eating and exercise habits.

Weight management for athletes -

This can create enormous confusion and has the potential to undo all the hard training that athletes put in if they take the wrong approach or look for quick fixes.

The goal of most if not all weight loss plans is to create a negative energy balance where more energy is used than consumed by the body.

There are many ways to achieve a negative energy balance and often diets promote cutting out entire food groups particularly carbohydrates and dairy foods to do this. While this might result in some quick weight loss initially, unfortunately, this loss is usually short term and unsustainable and weight lost is quickly regained.

Athletes should be focusing their exercise habits on performance development first and foremost. Training solely to burn extra calories leads to either eating more calories or over-training by under-fueling, neither of which results in fat loss.

Fat loss takes time. Water loss can happen overnight. Your goal should be fat loss, which means patience is required. Avoid being too aggressive with your calorie deficit goals. Aim for a to calorie deficit per day for healthy long-term fat loss that is sustainable while base training and building fitness.

Starving yourself with too few calories will make your caveman brain switch on starvation mode. This shuts down fitness development and locks down fat stores.

To decrease body fat, athletes should eat about — fewer calories per day but avoid eating fewer than You can also get your body composition measured by dual-energy X-ray absorptiometry DXA or underwater weighing.

These are more accurate but also tend to be expensive and harder to come by. SUMMARY Crash diets can increase your risk of illness and injury, as well as negatively affect your training and recovery. Therefore, avoid cutting your calorie intake by more than — calories per day.

However, restricting carbs too dramatically is not always best for athletes. Still, consume no less than 1. Cutting out added sugars is the healthiest way to reduce your total carb intake. To do so, check labels and minimize foods that contain added sugars like glucose, sucrose, and fructose.

Also, avoid cane juice, dextrin, maltodextrin, barley malt, caramel, fruit juice concentrate, fruit juice crystals, or other syrups. Instead, increase your intake of vegetables high in fiber. These will help keep you fuller for longer, making you feel more satisfied 12 , 13 , SUMMARY Eating less sugar and more fiber can help you reach your body fat goals.

Athletes should aim to eat no less than 1. Protein aids fat loss in several ways. To begin with, high-protein diets increase feelings of fullness and the number of calories burned during digestion.

They also help prevent muscle loss during periods of weight loss, including in well-trained athletes 5 , In fact, several studies show that eating 2—3 times more protein per day can help athletes retain more muscle while losing fat 9 , 16 , Therefore, athletes restricting their calories to lose weight should eat 0.

Consuming more than these amounts can displace other important nutrients, such as carbs, from your diet. This can limit your ability to train and maintain good sports performance 2 , 3 , 9 , SUMMARY Higher protein intakes help limit muscle loss while your weight is dropping.

Athletes should aim to consume 0. In addition to eating more protein, athletes can benefit from spreading their intake throughout the day In fact, 20—30 grams of protein per meal seems sufficient to stimulate muscles to produce protein for the following 2—3 hours.

Interestingly, studies in athletes show that spreading 80 grams of protein over 4 meals stimulates muscle protein production more than splitting it over 2 larger meals or 8 smaller ones 22 , Eating a snack with 40 grams of protein immediately before bedtime can also improve recovery from training and increase muscle protein synthesis during the night SUMMARY Eating 20—30 grams of protein every 3 hours, including right before bed, may help maintain muscle mass during weight loss.

Eating the right foods after training or competing is vital, especially when trying to lose body fat. Proper refueling is especially important for days with two training sessions or when you have fewer than eight hours of recovery time between workouts and events 2.

Athletes following carb-restricted diets should aim to consume between 0. Adding 20—25 grams of protein can further speed up recovery and promote protein production in your muscles 2. SUMMARY Consuming a good amount of carbs and protein immediately after training can help maintain your sports performance during weight loss.

Individuals attempting to lose weight are often at risk of losing some muscle in addition to fat. Athletes are no exception. Some muscle loss can be prevented by eating a sufficient amount of protein, avoiding crash diets, and lifting weights 3.

Research shows that both protein intake and strength-training exercises stimulate muscle protein synthesis.

Weigt maintenance is a balance between the Weight management for athletes consumed qthletes Weight management for athletes managfment energy expended. For athletes to maintain their weight while Weiht competitive, they must balance the Weight management for athletes equation. While our energy intake Carbohydrates with fast digestion from the food and beverages that we consume, our total daily energy expenditure TDEE is generated from multiple components, including resting metabolic rate RMRthe thermic effect of food TEF and physical activity energy expenditure PAEE. PAEE is the energy expenditure above resting that results from skeletal muscle contraction, including the required movement, balance and maintenance of posture. Both ExEE and NEAT can impact the ability to maintain weight. It is also likely that the foods and drinks they consume will vary.
