Welcome to the HPRC Blog. We've got lots of information here, from quick tips to in-depth posts about detailed human performance optimization topics.
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.
Fear of failure can prevent you from performing your best in many situations including combat, work, relationships, and daily life. Worry can take a bigger hold when you push it aside. For instance, while preparing to give a presentation and thinking, “I can’t be nervous,” you might actually feel more nervous!
As you face your fears, understand that fearing something will happen doesn't mean that it will happen. Ask yourself these kinds of questions:
- Why do I think I can’t be nervous? If I’m nervous, I’ll give a horrible talk.
- So if I’m nervous, I’m guaranteed to give a horrible talk? No, I’ve given good talks while nervous before.
- If nervousness leads to giving an awful talk, what’s the worst thing about that? I’d be embarrassed and people would walk away without having learned important material.
- What’s worse—embarrassment or people walking away without learning? I’d survive the embarrassment. People need to learn this stuff.
- Is this their last opportunity to learn? No, I’d take more steps to make sure they got it, despite an initially awful talk.

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.

Getting married again is a time of new beginnings. It’s often a time of challenges and changes too. While you’re celebrating your marriage and deciding what kind of stepparent you’ll be (if your partner has children), there are a few things you can do to stay happy:
- Maintain your identity as an individual—separate from your spouse. This will help you weather challenges with confidence. But strike a balance with staying close to your spouse too.
- Focus on each other. Sharing intimacy with your spouse includes a healthy sex life too. This helps you two connect regularly.
- Stay flexible. Often remarriage means juggling new responsibilities, living in a new place, or becoming a stepparent. Bending with whatever life throws at you means you’re less likely to break or falter.
- Keep a sense of humor. Laughing at yourself or the situations you find yourself in can help you keep perspective.
- Don’t take the place of a biological parent if you’re becoming a stepparent. Foster your own relationship with your stepchild and follow your partner’s lead.
- Remember how you felt when you fell in love. Keep those memories alive—they’ll help get you through tougher times.
Sleep is vital. Think about it: sleep loss causes performance to suffer, but getting plenty of sleep results in better performance. Most people wouldn’t consider going without food or water, and sleep is no different—it’s a necessity. Lack of sleep is equivalent to being drunk. In fact, after being awake for 18–20 hours, you’d function as if you had a blood-alcohol content of .1% (about four drinks for a 150-pound man). Little or no sleep affects your eye-hand coordination, reaction time, and multitasking abilities—and how you remember important sequences, remain attentive, and stay organized. If you’re tired, you may be able to learn skills and work well enough, but training while fatigued might impact your ability to do your best.
Many people believe that they can overcome being tired or “get used to it.” But evidence suggests sleeping only 6 hours can jeopardize your resilience, health, and well-being. As people become more sleep-deprived, they become less aware that they’re impaired. When someone says, “I’m used to being tired,” they’re simply used to having impaired awareness and judgment. When possible, sleep more to help boost your energy level, thinking ability, and readiness!
HPRC has received a lot of questions about phentermine, a prescription drug used for weight loss that’s similar to amphetamine. If you’re a service member, is it okay to use as long as you have a prescription? Will you pop positive on your drug test? Read the OPSS FAQ to find out answers to these questions.
For answers to other frequently asked questions that we’ve received, visit the FAQs section of OPSS. You can also visit the OPSS High-Risk Supplement List for information about certain dietary supplements that may pose a sport anti-doping or health risk.
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.
