HPRC Fitness Arena: Nutrition
Have you been watching what you eat and exercising regularly, but for some reason, the scale just won’t budge? You might be at a “plateau” in your weight-loss journey. But with continued effort and persistence, you can do it! If you want to shed those last few pounds, try these ideas on for size:
- Track it. To keep old, unhealthy eating habits at bay, keep a food diary or record your intake through the U.S. Department of Agriculture’s (USDA) SuperTracker. This online program helps you see where your calories are coming from. Don’t forget to watch your portion sizes too.
- Stick to your plan. Remember the fundamentals of a healthy eating plan: nutrient-rich, lean sources of protein such as fish, poultry, beans, nuts, and low-fat dairy products. Make sure to include whole grains, fruits, and vegetables too. It’s okay to indulge a little, but too many “cheat days” can ruin all your hard work.
- Eat protein. Protein helps preserve lean body mass (muscle) during weight loss, promote fat loss, and contribute to a feeling of fullness. Use HPRC’s Protein Requirements infosheet to calculate your individual protein needs.
- Rethink your drinks. Alcohol and sugar-sweetened beverages such as soda, sweet tea, juice, energy drinks, and sports drinks can add too many calories and prevent you from losing weight. Stick to water and low-fat milk (or soymilk) during meals and in-between to stay hydrated. Three servings of milk per day is the limit though!
- Shake things up. Varying the type, intensity, duration, and frequency of your exercise is a great way to challenge yourself and prevent boredom—and it can make a big difference toward reaching your goal.
Whatever you do, don’t give up. Achieving and maintaining a healthy weight is better for your health, career, and performance.
Chia (Salvia hispanica) seeds are rich in omega-3 fatty acids and fiber. As such, they have become a popular food item, and you can also find chia (seeds and oil) in many dietary supplements marketed to support heart and digestive health. On its own, chia will not produce a positive drug test. However, when you look at ingredient lists on product labels, don’t confuse Salvia hispanica (chia) with Salvia divinorum (Diviner’s sage), which is banned by some services. There are many types of salvia, so please read the OPSS FAQ about salvia for more information. If you’re interested in learning more about chia seeds, visit this webpage from MedlinePlus.
We all want to serve healthy, nourishing food to our families. But sometimes we let our best intentions get in the way. You wouldn’t head into the woods without a plan, map, or GPS—so why begin your day with little thought about eating well? Start this year off right by learning and putting these easy meal-planning practices into place. Once you’ve established these habits, you’ll be amazed at how good it feels to map out your meals. The more you practice HPRC’s strategies—the faster and fitter you’ll be—a huge savings to your body, time, and wallet. Read more here.
Several of the service branches have recently updated their body fat composition standards. The U.S. Armed Forces uses body composition (a measure of a person’s body fat) as one factor to determine a service member’s fitness level.
Each service has its own standards (within DoD guidelines 1308.1) and evaluation methods. Whether you’re a healthcare provider or service member, check out HPRC’s Body Fat Standards by Service Branch infosheet to compare the different service standards.
Each year, the average adult catches 2–3 colds lasting 7–9 days each. That’s almost an entire month—YIKES! What you eat and drink each day can impact your body’s resistance to sickness. Want to keep the doctor away? Eat 9 servings of colorful fruits and vegetables daily.
Choosing nutritious foods when you’re sick shortens the number of days you feel badly and helps you feel better while you’re recovering. Here are some tips to help you get well soon:
- Grab a mug of chicken soup to clear your head and soothe your throat.
- Drink tea (black, green or white) to break up chest congestion and stay hydrated. Tea also contains a group of antioxidants, which could boost overall immunity.
- Take a spoonful of honey before bedtime to quiet a cough. You could also add honey and lemon juice to one cup of boiling water. (Not for kids under one year of age.)
These recommendations might have previously been considered folklore or old wives’ tales, but science now shows that Grandma knew best!
Daily exposure to cold weather increases your nutritional needs. But if you only PT outside for an hour or so a day, workout in a gym, and spend the rest of your time indoors, your daily food and fluid needs don’t change much—even when it’s cold outside. If you’re training in the cold for long periods of time, such as during field deployment or cold weather operations, here are a few ways to help maintain peak performance:
- Calories. Moving through snow and icy terrain while wearing heavy gear causes your body to use more energy. Consume three to four standard MREs or three MCW/LRP rations per day to meet your energy needs. (At times you may have to force yourself to eat.)
- Carbohydrates. Carbs are your body’s first choice for energy. When your caloric needs increase, you’ll need to eat more carbs. Be sure to eat high-carb foods such as rice, noodles, bread, First Strike Bar, fruit or sports bars, crackers, granola, pretzels, and carb-fortified drink mixes from your MRE or MCW/LRP rations. Store snacks in your pockets so you can fuel on the go, between meals, and before bed.
- Hydration. Yes, you can still get dehydrated in the cold. Cold temperatures increase your fluid loss through increased urine output, breathing, and sweating (due to insulated clothing and intensity and duration of exercise). Fuel with fluids (excluding alcohol) even when you’re not thirsty. Make sure to monitor your hydration status by checking your urine color.
Remember, this isn’t the time to start a new diet (such as a low-carb diet) or lose weight, so fuel up to perform well.
If you’re feeling stressed, don’t rely on liquid relaxation products to relieve your tension. While energy drinks are promoted to give you an extra boost, relaxation drinks* are marketed to do just the opposite and help you, well, relax. These products commonly contain the amino acid theanine, as well as several different plant-based ingredients. But the science doesn’t support the use of relaxation drinks to decrease stress or anxiety, and consumers should be cautious of two ingredients: kava and melatonin. Bottom line, if you’re feeling stressed, try to identify the cause, and then use stress management strategies backed by scientific evidence. Read more here.
For many fans, watching football means indulging in comfort food and drinks—and lounging around on Saturdays and Sundays. It’s a way to round out the weekend and relax before the start of another workweek. But even one day of binging on game-day food and relaxation can ruin your regular healthy routine. The average football game consists of about 11 minutes of actual play—so you’re watching huddles, replays, and commercials in-between. Use that downtime to your advantage, call an audible, and get moving during time-outs!
- Play some flag football at halftime.
- Complete a quick workout during commercial breaks.
- Remember to make healthy food choices too.

Who says that figuring out what to prepare and eat over the coming holiday weeks needs to be stressful? Worrying about choosing appropriate food gifts? How about gaining weight and never taking it off—again? These concerns are often on our minds at this time of year. So here are some tips to enjoy a healthy holiday.
- Make recipes more nutritious. Use evaporated skim milk in place of heavy cream in soups, quiches, pies, and other recipes. Substitute whole-wheat for white flour in bread, gravy, and cookie recipes.
- Reduce your calorie intake. Choose more fruits and vegetables at each meal. Don’t skip a meal—because you could overeat at the next meal. Eat smaller portions instead.
- Pick healthy gifts. Offer a welcome basket of fresh fruit or assorted packages of nuts and dried fruit. Put together a basket of healthy ingredients for a quick meal. Give a personal favorite such as a special bread, olive oil, or jam.
Challenge yourself by putting at least one tip into practice. It guarantees your holidays will be less stressful!
We all want to use our food resources and time wisely. Let’s talk about ways to save minutes and money. As the holidays approach, we want quick, easy meals to fortify us. Using the bones from our holiday meats can make an almost “free” extra meal or two. Helpful hint: store the bones in the freezer until you are ready to get cooking!
These tasty soups are healthy and affordable:
- Bean Soup. Put a ham bone in a crockpot. Cover with 8 cups of water. Add one pound of rinsed, dried pinto beans. Season as desired—jalapeno peppers and cilantro are especially good. Cook on High for 5–6 hours or Low for 11–12 hours. Skim the layer of fat from the top. Chop and add any leftover ham to the soup.
- Turkey Vegetable Soup. Put turkey bones in a large pot. Cover with 6–8 cups of water and bring to a boil. Turn the heat down and simmer for 30 minutes. Remove the bones and strain the broth. Add frozen corn, green beans, grated carrots, and instant brown rice. Bring to a boil and simmer for 10 minutes. Add chopped pieces of turkey meat if desired. Season with black pepper.
Who knew making soups could be so simple? These meals just might become a mainstay of your recipe toolkit!
