Wanting some holistic strategies to enhance your performance? Check out the “One Shot One Kill (OSOK) Performance Enhancement Program” that shows Warfighters how to set up and manage their own performance-enhancement system. OSOK is designed not only to enhance performance but also to jumpstart Warfighter resilience. It builds on the skills that Warfighters already possess and then teaches new ones as needed.
There are two ways you can use OSOK: as an individual through “OSOK Solo” and as a unit/group through “OSOK-IP Unit.” Both highlight “10 Rules of Engagement” and provide seven core modules: Controlled Response, Mind Tactics, Performance-Based Nutrition, Primal Fitness, Purpose, Code, and Recharge. OSOK also provides self-assessment forms so you can track your progress over time.

On January 14, 2014 the Marine Corps released MARADMIN 010/14, which details the new requirements for the Marine Corps Embassy Security Group. Marines who want to travel the globe and provide security services for U.S. embassies and consulates now have to meet new, revised standards. Among other things, Marines must be at least 64 inches tall so they can adequately view all areas from Post One (point of entry control at diplomatic posts). In addition, physical fitness standards have changed: Marines will have to achieve 1st Class PFT scores. If you haven’t yet achieved this level of fitness, we have some tips. First and foremost, for optimal fitness, be sure to train smarter, not harder.
Do milk products make you queasy, gassy, or—worse—send you running to the bathroom? If so, you might have lactose intolerance, a condition caused by a deficiency of lactase, an enzyme produced in the small intestine. Lactase breaks down lactose, a naturally occurring sugar present in milk and milk products.
Symptoms of lactose intolerance include nausea, gas, cramping, and diarrhea and usually occur 30 minutes to two hours after eating milk products. Anyone (at any age) can develop lactose intolerance, but it’s more common among adults of African, American Indian, Asian, Jewish, or Mexican heritage. People who have digestive diseases such as Crohn’s disease, ulcerative colitis, or celiac disease are more likely to be lactose intolerant too.
Some people with lactose intolerance have to avoid all milk products, but others can handle small amounts of cultured milk products such as yogurt, kefir, or buttermilk. If you think you have lactose intolerance, experiment with milk products to see what you can handle.
Many processed foods (including MREs) contain milk products, so learn to be label-savvy: Look for words on food packages that indicate a product might have milk or milk products such as whey, curds, milk byproducts, dry milk solids, and nonfat dry milk powder. Missing your ice cream? Over-the-counter enzyme products can help you tolerate lactose-containing foods if taken with the first bite of food.
Don’t confuse lactose intolerance with milk allergy, an immune response to casein or whey, two proteins found in milk. Symptoms of milk allergy are typically mild and include:
- Runny nose, sneezing, or shortness of breath
- Swollen lips, tongue, or throat
- Rash, hives, or itchy skin
However, severe milk allergy can cause anaphylaxis, a serious, life-threatening condition that requires immediate medical attention. People with severe milk allergy should read labels carefully to avoid all milk products.
Of course, limiting or avoiding milk products could put you at greater risk of developing osteoporosis or “brittle bones.” That’s because milk products contain calcium, an essential nutrient for healthy bones. Look for other calcium-rich foods such as dark-green leafy vegetables, almonds, beans, shellfish, or calcium-fortified juices, soymilk, or almond milk.
To learn more about lactose intolerance, read this informative article from the National Digestive Diseases Information Clearinghouse.
There’s an old adage you may have heard: “Eat after eight, put on weight.” And maybe you’ve experienced it first-hand: You noticed that eating those late night pizzas and ice cream really packed on the pounds. But was your weight gain due to timing or just the high calorie counts? According to research in the field of circadian rhythms (CRs)—the 24-hour cycle of your body’s biological, hormonal, and behavioral patterns—it seems that when you eat could be just as important to weight gain as what you eat.
Deep within your brain sits a small cluster of nerve cells—a “master clock” of sorts—that’s responsible for orchestrating your CRs. Each biological system in your body works on a different CR schedule, and the master clock keeps all the schedules in sync. For example, CRs influence your body’s production of the hormones that regulate hunger, as well as how your body uses and stores fats and sugar, ultimately influencing your body weight, performance, and overall health. Other hormones, such as the ones that tell you when you’re full, are switched on or off according to a variety of inputs.
The two greatest influences on how well your master clock is able to keep things in sync are light and food. Light tells your brain how much sleep you get (think: eyes closed, less light). Food (smell, taste, and consumption) tells your body to produce a myriad of chemicals. As a result, staying up late at night, working shifts, and eating at all hours of the day and night—whether voluntarily or due to the demands of overseas deployments, training demands, shift-work schedules, and even parenthood—can play havoc with your circadian rhythms.
In an interesting twist, not only do CRs influence hunger and body weight, but excess body fat and/or a high-fat diet may disrupt CRs. This can lead to further weight gain, culminating in a collection of health problems known as “metabolic syndrome.” In the U.S., regular loss of sleep closely parallels the occurrence of metabolic syndrome. In addition, researchers have found that people who sleep less or have poor-quality sleep are more likely to become obese.
What to do? Make a conscious effort to “normalize” your daily routines as much as possible to maintain regular mealtimes. Whether you choose to eat three regular-sized meals or four to six smaller meals a day, space them out through the daylight hours to take advantage of your body’s natural rhythms. Here are some suggestions to avoid eating late at night:
- Try to eat a balanced dinner at least two hours before you go to bed, and take a walk afterwards when possible.
- Sip on soothing herbal tea or flavored water (without sugar).
- Be aware that watching TV (especially food-related ads) can trigger your desire to eat.
- Sometimes it can help to create new nighttime rituals that don’t involve eating, such as light stretching or yoga, taking a warm bath, listening to soothing music, or reading (or listening to) a book.
But if you find yourself up late at night—whether it’s due to a hard day at work, regular shiftwork, or temporary shifts due to jet lag or an infant’s night feedings—resist the urge to snack out of boredom or to “keep your energy up.” Shift workers should pack or purchase a healthy meal to eat during their work hours—one that includes lean protein and complex carbohydrates such as whole grains, fruits, and vegetables. Eat early in the shift if possible, so you’ll have the energy you need to think and move efficiently. Travelers and parents should look for healthy snacks that follow a similar pattern. And try to limit coffee, tea, and other sources of caffeine to just two to four servings a day.
Of course, eating is just one half of the CR equation. Getting enough sleep is important too, so read HPRC’s overview for great tips on how Warfighters can improve their sleep.
Holiday parties provide opportunities to relax and enjoy good food and good times with family, friends, and colleagues. But they also can derail your weight and fitness goals. Buffet tables laden with calorie-rich treats and beverages can weaken the resolve of even the most committed folks. To keep yourself on track, remember these tips:
- Never go to a party hungry. Eat a protein-rich food before you go. Protein foods tell your brain that you’re satisfied and help you avoid overindulging. Low-fat milk or yogurt or a handful of nuts are great choices.
- Follow the MyPlate strategies for filling your party plate: Fill half your plate with fruits and vegetables then fill the rest with whole grains and lean protein such as fish or chicken.
- Choose wine over fancy mixed drinks or beer, and be sure to drink in moderation: one drink for women and two drinks for men. Sip slowly to make your drink last through the evening.
- If it’s a potluck, you really are in luck. Offer to bring a healthy salad or entrée, and fill your plate with your own delicious creation.
- Don’t waste your calories (and taste buds) on desserts that you don’t absolutely love. Choose your favorite and then share it with a friend. You’ll eat slower while you and your friend chat, and cherish the moment as much as the sweet!
In a 1960s TV cartoon series, George Jetson of The Jetsons simply popped a pill when he wanted to eat. “Dinner in a pill” was promised as the food of the future. So why hasn’t technology delivered on its promise? Simply put, no dietary supplement can reproduce the aromas, flavors, textures, or nutritional value of oven-roasted turkey, crusty, fresh-baked bread, juicy ripe pineapple, fragrant hot tea, or any other wholesome, delicious, performance-enhancing real food or beverage. And substituting dietary supplements for real food won’t help performance either – check out our video here. So skip supplements—not meals. To learn more about how real foods should come before dietary supplements, check out HPRC’s article in Operation Supplement Safety (OPSS).
The phrase “Garbage in, garbage out” was coined first by computer experts back in the 1960s. Since then, the phrase has gained a wider usage—even to the world of performance nutrition. Providing your body with high-quality fuels and nutrients is crucial to optimizing your performance. Like the poorly fueled runner in HPRC’s video, you’re likely to find that a diet of high-fat or sugary foods and drinks (“garbage in”) produces less than optimal results (“garbage out”). Instead, choose wholesome foods such as lean meats and fish, fresh fruits and vegetables, whole grains, and low-fat dairy products, which provide high-quality fuels and nutrients.
Food and health are hot topics these days. Just turn on the TV, pick up a magazine, or glance at the margins of your social networking site and you’ll hear and read about the supposed health benefits of dietary supplements containing this or that food component and the promises that they will “burn belly fat” or some similar claim.
Many of these promising food components belong to a group of compounds referred to as phytochemicals—chemicals produced by plants as a means of protecting the plants from various diseases.
Interestingly, when you eat plants (such as fruits and vegetables), the phytochemicals they contain might protect you from disease too. Researchers have found that people who eat a lot of fruits and vegetables have lower rates of heart disease, cancer, diabetes, and many other diseases. Scientists haven’t discovered exactly how these compounds work to protect us, but they have discovered that they seem to have a synergistic effect. That is, the compounds seem to work better in combination, especially when they are supplied in their natural form—whole foods. Consuming isolated single compounds, as in dietary supplements, rarely has the same beneficial effect as eating the whole food. See these resources about fruits and vegetables and how they may impact your overall health.
Focusing on single nutrients (in pill form) is not only expensive, it just doesn’t offer the promise that a balanced, varied diet can. Focus on food, instead. For more information about the benefits of food versus dietary supplements, check out this OPSS brochure, “Nutrition: Fueled for Fitness.”
June is National Fresh Fruits and Vegetables Month. And it’s no wonder—during the warm summer months many fresh fruits and vegetables are at their peak. So take advantage of nature’s bounty and make an effort to include more fruits and vegetables into your family’s diet. Here are some tips to help:
- Start early: Top your morning breakfast cereal with fresh berries, bananas, or peaches for added flavor and nutrition.
- Add some crisp lettuce leaves and juicy tomato slices to a sandwich or wrap.
- Kids love foods they can “dip,” so encourage them to dip their veggies in a delicious, healthy fresh tomato salsa.
- Keep fresh veggies and fruits on a platter in the refrigerator so kids (and you!) can grab some any time—cooling off by the pool, reading a book, or cooking dinner.
- Go to a farmers’ market to find the freshest, in-season produce.
- Plant your own garden—or just a small tomato plant on the back porch. There’s nothing quite like homegrown fruits and vegetables.
- Have some dessert! Fruits are full of natural sweetness—the perfect way to round out a meal.
Eating fruits and vegetables may reduce your risk of cancer, diabetes, and many other diseases. To find out how many fruits and vegetables you and your family should be eating, use this great calculator from the Centers for Disease Control and Prevention. The U.S. Department of Agriculture has more information about the benefits of eating fruits and vegetables as well as lots of great tips to help you incorporate fruits and vegetables into your diet.
Synthetic drugs are laboratory-made substances marketed and sold as alternatives to illegal drugs such as marijuana, cocaine, and amphetamines. Although most are advertised as “all-natural,” they may have serious health effects and violate the Uniform Code of Military Justice (UCMJ). HPRC takes a look at two examples of synthetic drugs, their legal status, and how they can affect service members in “HPRC’s Answer: Synthetic Drugs of Abuse.”
