Published by the Iowa High School Athletic Association The keys to developing wrestling potential are a healthy, balanced diet, acquiring the needed wrestling skills, proper conditioning, and getting adequate rest. By following sound advice about wrestling nutrition and weight control, wrestlers can improve their performance on the mat and in the classroom. The benefits of proper nutrition and weight control, to the mind and the body, have been well documented. Likewise, the hazards of extreme weight loss and poor nutritional habits are also well documented. Mood swings, irritability, decrease in academic performance, and loss of athletic performance can all result from extreme weight loss and poor nutritional habits. The best weight for wrestlers, or anyone for that matter, is one that is safe and can be comfortably maintained by eating a healthy, balanced diet. Wrestlers should be able to concentrate more on developing wrestling skills, than on maintaining, or losing, weight. Those who spend more time thinking about food than wrestling are probably trying to lose too much weight and/or eating the wrong foods. Appropriate wrestling weight is that weight which can be maintained by eating a healthy, balanced diet. Seven percent (7%) body fat has been established by many medical authorities across the country as the safe, minimal percent body fat for high school wrestlers. Body fat testing is the only scientific method of predicting a safe, minimal wrestling weight. By losing weight too quickly, or going below 7% body fat, a wrestler risks losing muscle along with fat. This results in decreased muscular endurance and strength. Not every wrestler can, or should, attempt to reach 7% body fat. Most high school wrestlers will perform very well at a body fat percentage above 7%. If a wrestler is above 7% body fat, there is no reason to believe that wrestling performance will improve simply by losing weight. The Iowa High School Athletic Association’s Body Composition Testing Rule states, “The lowest certifiable wrestling weight of each wrestler will be determined by predicting a wrestler’s weight at 7% body fat, minus 3% body weight (due to the approximate error in testing methods).” A wrestler’s lowest certifiable weight is not necessarily the weight he should be trying to achieve, but it is the minimum, safe weight he could achieve under ideal circumstances. If a wrestler does decide to lose weight to reach their lowest, certifiable weight, they should lose no more than 2-3 pounds per week. The only way the body can lose more than 3 pounds a week is through dehydration and excessively 1 restricted food intake. Both of these practices cause the body to lose muscle and water along with the fat. Dehydration and excessively restricted food intake result in decreased strength, muscular endurance, stamina, and concentration. Dehydration is the most detrimental method of losing weight and causes the most rapid decrease in strength, endurance, and mental alertness. Research indicates that the loss of as little as 2% of one's body weight through dehydration can cause significant performance loss! A 2% weight loss for someone weighing 150 pounds is only 3 pounds! To prevent dehydration, the use of rubber, vinyl, and plastic suits, saunas, whirlpools, diuretics, or other methods of quick weight loss must be eliminated. They are against the rules, hurt performance, and can prove to be dangerous to one's health. A simple, effective method of determining adequate hydration is to check the color of one’s urine! Yellow urine indicates dehydration and pale, or clear urine, indicates adequate hydration. The following guidelines will also help ensure proper hydration: 1) drink at least 8, 8 ounce glasses of fluids a day, 2) drink 5-6 swallows of fluids every 15-20 minutes during exercise, 3) for each pound of weight lost during practice, drink 2, 8 ounce glasses of fluids, 4) thirst is a poor indicator of how much to drink; drink more than just enough to ...
Heart Healthy Diet: Low Fat, Low Cholesterol, Low Sodium Diet Purpose of the diet Control and / or decrease levels of cholesterol in your blood. Control and / or decrease blood pressure and / or fluid retention. Cholesterol This fat-like substance is necessary for good health. However, high levels in the blood can cause heart and blood vessel diseases. Our bodies make cholesterol. We also get it from eating foods from animals (meats, milk, eggs, cheese, butter). Foods from plants (fruits, vegetables, grains) do not contain cholesterol. Saturated fats These fats are generally solid at room temperature. They tend to increase blood cholesterol levels. Trans fatty acids These are fats that can raise cholesterol levels like saturated fat does. Trans fats are usually listed as partially hydrogenated oils. Polyunsaturated and monounsaturated fats These fats are generally liquid at room temperature. Some can lower blood cholesterol levels.

Page 2 How can I lower my blood cholesterol level? Decrease total fat intake, especially saturated and trans fats. Saturated fats are mainly in animal foods. Trans fats come mostly from partially hydrogenated plant oils. Foods that may contain trans fats include store bought baked goods, non-dairy whipped toppings, cream substitutes, some crackers and cookies, and many deep fried foods. To check for trans fats in a food, look for any oil that is “partially hydrogenated” in the ingredients on food labels. If a food has less than half a gram of trans fat per serving, the food manufacturer can list “zero grams of trans fat” on the food label, so it is best to check the ingredients for partially hydrogenated oils. Limit high cholesterol foods. Egg yolks, fatty meats, organ meats, butter, whole milk and other high fat dairy products are high cholesterol foods. Substitute monounsaturated fat or polyunsaturated fat for saturated fat in your diet. Monounsaturated fats include olive oil, peanut oil and canola oil. Safflower, corn and sunflower oils, and most margarines and salad dressings are examples of polyunsaturated fats. Also, fish has a higher content of polyunsaturated fat than red meat. A special note on fish: Many fish are low fat. Some fish that have a higher fat content such as salmon are high in a kind of fat called omega 3 fatty acids. This type of fat has been shown to be very heart healthy. It is recommended to eat fish three times a week for this reason. One caution: consider how you prepare it so that you don’t add large amounts of undesired fats. Baking, broiling, grilling or poaching fish is best. What is sodium? Sodium is a mineral that is necessary for good health and is present in all foods. Most people eat more sodium than they need. If the body cannot get rid of the extra sodium, fluid builds up. Extra fluid increases the work of the heart and kidneys, and may increase blood pressure. Eating less sodium may help control these problems. You will sometimes see the term sodium abbreviated "Na", as in NaCl (Sodium Chloride), which is table salt. The recommended sodium intake per day for most people is no more than 2300 milligrams (mg). For anyone who has high blood pressure, is over 50, or is African American, the sodium intake is 1,500 mg. Page 3 Sodium Guidelines To choose foods that are healthier for you, look for these labels: Sodium-free – less than 5 milligrams of sodium per serving Very low-sodium – 35 milligrams or less per serving Low-sodium – 140 milligrams or less per serving Reduced sodium – usual sodium level is reduced by 25 percent Unsalted, no salt added or without added salt – made without the salt, but still has the sodium that's a natural part of the food Know Your Salt When you are on a No Salt Added diet, even a small amount of salt has a lot of sodium in it. Amount of Sodium in Salt ¼ teaspoon salt 600 milligrams of sodium ½ teaspoon salt 1,200 milligrams of sodium ¾ teaspoon salt 1,800 milligrams of sodium 1 teaspoon salt 2,300 milligrams of sodium 1 teaspoon baking soda 1,000 milligrams of sodium How can I limit sodium?

Healthy Eating Plan 1800 Calorie Plan There are many different types of eating plans available; however, the key to success is finding one that works for you. One key ingredient for a meal plan to work is consistency. Many of us fail to keep consistency in our lives or we stay consistent with bad habits. Two examples that come to mind include skipping meals and breakfast. Failure to break-the-fast every day and skipping meals improves the chance that you will fail to reach your goals. Eating breakfast and consuming small meals (4 to 6 per day) prevents binge eating, nighttime snacking, and weight gain. It also keeps your metabolic rate at an optimal pace. The body requires fuel to keep your metabolism burning. Think of metabolism as a campfire. To keep a fire burning strong, it must be fed small doses of wood (i.e., fuel). Dropping a large log onto the fire will keep the fire burning, but not as effectively as if it was fed small portions of wood. With the fire still in mind, you have to look at its preferred fuel choice. Adding paper or “empty calories”, the fire will burn through it very quickly. As a result, the fire becomes starved and must be fed very often. Now if you added a mixture of paper and wood, the fire will have enough fuel to burn for a longer period of time. The wood will satisfy the fire’s appetite more than the paper. Wood is to fire as protein is to humans. Your diet should always include a source of protein at each meal and snack. Serving Sizes Serving sizes are not designed to tell you how much you should eat at each meal, but rather, to give you a pattern with which to compare your intake with your goals. Based your specific goals, try to consume the appropriate amount of food based on the following serving sizes. Breads, Cereal, Rice, and Pasta Group One serving = 80 calories or one of the following: 1 slice bread, 2 slices “extra thin” or “diet” bread, ½ English muffin, ½ frankfurter or hamburger bun, 1 small dinner roll, ½ cup starchy vegetables, ½ cup mashed or 1 small baked potato, ½ cup cooked cereal, pasta, rice, 1 tortilla 6” across, 1 ounce cold cereal, 4-6 crackers, 3 cups air popped popcorn, 2 rice cakes or 5 mini cakes. Fruits One serving = 60-80 calories or one of the following: 1 medium portion of fresh fruit: orange, apple, banana, 2 Tbsp raisins, ¼ cup dehydrated fruit; ½ cup cooked or canned fruit, ½ cup fruit juice ...
Helpful Guidelines for Successful Weight Loss Weight loss should occur when you eat fewer calories than you burn. Increasing physical activity while limiting your calories will increase your rate of weight loss. Increasing physical activity will also help you to maintain your weight after weight loss. Discuss appropriate calorie levels and serving sizes with your dietitian. 1. Keep a written food and physical activity journal. 2. Weigh yourself once per week at the same time of day, with the same amount of clothing, and on the same scale. 3. Eat breakfast everyday and do not skip meals. Skipping meals can lead to extreme hunger, overeating and poor food choices. 4. Plan your meals and eat around the same time every day. 5. Pick an eating area at home and/or work. 6. Turn off the TV and/or computer during meals and snacks. 7. Eat slowly. Take 30 minutes for a meal. It takes 20 minutes before you feel full, so wait 20 minutes after your first serving before taking a second serving. 8. Eat protein foods first to help you feel full sooner. 9. Read food labels to help control portions of food. 10. Eat less fat and sugar. Eat more fiber, including fresh fruits/vegetables and whole grains. 11. Limit restaurant and fast food meals. 12. Don’t keep problem foods around the house and/or at work. A problem food is a food that you are likely to eat too much of or too often if readily available. 13. Drink at least 8 cups (64 ounces) of liquids per day. Focus on calorie-free, caffeine-free beverages. 14. Get adequate sleep each night (7-9 hours).

Food Preparation Use lowfat cooking methods such as baking, grilling, boiling, poaching, broiling, roasting, steaming or microwaving without additional fat. Avoid or limit frying. Place meat on a rack so the fat will drain off during cooking. Remove skin from poultry before cooking. Trim all visible fat from food (i.e. poultry and meat) before cooking. Use non-stick cookware or cooking sprays. Use egg whites or egg substitute in place of whole eggs. Season food with spices, butter flavoring (such as Butter Buds®), lemon or low-fat dressings. Limit high-fat sauces or gravies such as sour cream, regular salad dressings, full-fat gravy, and cream or cheese sauces (such as Hollandaise or Alfredo sauce). Use a sugar substitute in place of sugar. Replace sugar in recipes with a sugar substitute that can be used in baking or cooking.

Eating Disorders Anorexia Nervosa Someone with this condition may be intensely afraid of being overweight and claim to feel fat even if they are severely underweight. They might reject food entirely, vomit to be rid of the food, and exercise to the extreme to achieve thinness. Bulimia Someone with bulimia may vomit intentionally, or use laxatives to rid the body of food. Often bulimics will ingest huge amounts of food (binge) before vomiting or they may alternate bingeing with severe dieting. A bulimic is not necessarily overweight or underweight.
