As university life picks up speed, maintaining a balanced diet can often fall by the wayside. Between classes, study sessions, and social activities, it’s easy to grab whatever is convenient. However, good nutrition is essential not only for keeping your energy levels up but also for enhancing your academic performance, supporting mental focus, and maintaining overall health. Here are some practical tips on stocking your dorm or apartment with nutritious, affordable, and convenient foods.

Power Up with Protein

Protein is key for staying full and supporting muscle recovery, especially if you’re hitting the gym. Here are a few budget-friendly, protein-rich foods that are easy to store and prepare:

1. Greek Yogurt: A versatile, protein-rich option, Greek yogurt is great for breakfast or a post-workout snack. Choose plain varieties to avoid added sugars, and mix in fresh fruit or granola for added flavor and nutrients.

2. Canned Tuna or Salmon: These are affordable, shelf-stable sources of protein. Mix with light mayo, mustard, and veggies for a quick meal, or stuff into a whole-grain pita.

3. Eggs: Eggs are a cost-effective protein source. Hard boil a batch at the start of the week for easy grab-and-go snacks, or cook up an omelet loaded with veggies for a nutritious meal.

Color Your Plate

Including a variety of colorful fruits and vegetables in your diet ensures you’re getting a range of vitamins, minerals, and antioxidants. Here are some options that are easy to keep on hand:

1. Baby Carrots and Hummus: A crunchy, satisfying snack that pairs well with hummus, which also provides a bit of protein and fiber.

2. Frozen Berries: Just as nutritious as fresh, frozen berries are perfect for smoothies, yogurt toppings, or thawing for a quick snack.

3. Spinach and Mixed Greens: Pre-washed greens are a convenient base for salads or can be added to sandwiches, wraps, or smoothies for an extra nutrient boost.

Quick and Easy Meal Ideas

When time is tight, having simple meal options can help you avoid less healthy choices:

1. Overnight Oats: Combine rolled oats with Greek yogurt or milk and add your favorite toppings like nuts and berries. Prepare it the night before for a quick, ready-to-eat breakfast.

2. Protein Smoothies: Blend protein powder, spinach, frozen berries, and a banana with milk for a quick, nutritious meal.

3. Whole-Grain Wraps: Keep whole-grain tortillas on hand for easy wraps. Fill with lean protein like turkey, mixed greens, and veggies, and add a spread of hummus or avocado for healthy fats.

Budget-Friendly Tips

Eating well on a budget is possible with a few smart strategies:

1. Buy in Bulk: Bulk items like oats, rice, and nuts are often cheaper and can be stored for long periods.

2. Shop Seasonal Produce: Seasonal fruits and vegetables tend to be less expensive and more flavorful. Check out local markets or the produce section for deals.

3. Frozen Options: Frozen fruits and vegetables are often more affordable than fresh and retain their nutritional value. They’re perfect for quick, healthy meals.

By keeping your dorm or apartment stocked with these nutritious, budget-friendly options, you’ll be better prepared to fuel your body and mind for the demands of university life. Remember, healthy eating doesn’t have to be complicated or expensive—a little planning can go a long way.

So, if you’re like me and have been scrolling through the various social media outlets out there, you might have been seeing an uptick in a very niche fitness trend. Lately it’s all I see on TikTok, and I will admit it is intriguing watching these people on social media freeze their butts off in a cold tub of water. Often, the results are hilarious as people realize how unbearable sitting in a tub full of ice water really is. I mean look at this video and tell me whether you think this looks enjoyable. I think not, but watching these poor people suffer did have the gears turning in my mind about whether there is anything that can come out of subjecting your body to frigid temperatures, and maybe I should be partaking more regularly in these freezing experiences.

Cold Water Therapy Through the Ages

The experience of taking plunges into cold or even freezing water can be traced all the way back to nearly six millennia ago. Ice baths and cold-water immersion have been used for recovery purposes for centuries. Even as far back as 3500 B.C., the ancient Egyptian medical textbook Edwin Smith Papyrus (named for Edwin Smith, who purchased it in 1862), referring to using freezing water as a therapeutic modality. The ancient Greek physician Hippocrates in the 4th century B.C. wrote about the benefits of immersion in his work On Airs, Waters, and Places.

Looking more recently, in the 19th century, researchers looked at immersion to alleviate various ailments. Scottish physician William Cullen began prescribing cold-water therapy for patients with a wide range of symptoms including fever, inflammation, depression, and even insomnia. In the 1960s, D.H. Clark investigated cold-water immersion for post-exercise benefits. Throughout millennia and centuries, there have been numerous accounts of the benefits of immersion, both medicinal and therapeutic. But as with any modality, there is a delicate balance between the risks and the benefits.

What Are the Benefits?

Over time, a lot of work and studying has been done to investigate the benefits of cold plunges and cold-water immersion and a possible therapy for many different symptoms. There are a couple of things to consider when doing ice baths. To start, benefits of cold plunges have been studied thoroughly throughout the past couple centuries, and it has been found to reduce inflammation of sore and aching muscles, help sleep, and limit inflammatory response in the body. Anecdotally, many recreational and professional athletes swear by ice baths to help their bodies and boost their energy levels.

Know the Risks

But there are some key risks to keep in mind before plunging into freezing cold water. The biggest risk is the shock associated with plunging into cold water and the sensation that it “might take your breath away,” but a good way to combat this is focusing on breathing. Also, there is a risk for those with cardiovascular diseases as the cold water will constrict the blood vessels and create a risk for reduced blood flow. All these risks can be serious and should be discussed with a physician prior to cold-water immersion.

Something to Consider

With the introduction of cold temperatures to rehabilitate athletes and non-athletes, the benefits have proven to be significant and is something even the recreational athlete should consider.

VO2 max testing, or graded exercise testing, is a treadmill run or cycle to volitional fatigue—or pretty much going until you must stop. The test will tell us how many liters of oxygen you are able to take in and use for cellular respiration.

Physiologically, people use oxygen for a variety of things. The main purpose is for the oxygen to get into the cells’ mitochondria so that it can be used to generate adenosine triphosphate (ATP), which is the main energy source in the body. People use ATP to do pretty much everything: move our muscles, think, and even digest food. So the more oxygen you can take in and convert to energy, the longer and faster you can run due to this surplus of energy you are making at the cellular level.

What the Test Is Like

The test starts at a low speed and no incline on the treadmill. Then every so often the treadmill gets a little faster and a little higher. The increases are almost unnoticed and most start out walking. On the other hand, on the cycle, the resistance gets a little harder occasionally and the participant is expected to maintain the same rotations per minute (RPM). With both tests, the person is expected to go until they feel they must stop, when their workload is too great to maintain or their legs become too fatigued to continue.

What the Test Measures

While exercising, you will be hooked up to different devices to monitor your vitals such as a heart rate monitor and a ventilator of sorts. Some tests will also measure blood pressure and rate of perceived exertion. Trainers can use the information from these devices to generate a customized endurance program for you to push you to increase your VO2 max, and in turn, your overall endurance. VO2 max testing is a great way to know where you are currently at in your endurance training. It is comparable to doing repetition max testing on weights in strength training.

How the Results Can Shape Your Training

Trainers can utilize the data from a VO2 max test to make a program customized to your physiology. From a VO2 max test we can see what your heart rate maximum is exactly, and using these numbers we can get more accurate training zones for you. The ventilator gives a variety of useful data such as your aerobic threshold, or the point when you really start to breathe hard. This is the point where a person really starts to hate running, so knowing this point can help us stay below that more often, making the training more enjoyable while still receiving the benefits. Knowing different heart rate zones can help prevent overtraining and help push you to your fullest capacity, causing your body to adapt and consume more oxygen.

The measurements of blood pressure and perceived exertion are more common in a clinical setting to ensure normal responses to exercise, so they are not always necessary in healthy populations. The trainer can use rate of perceived exertion, however, to know how a person feels at certain running speeds. If someone feels that they are working very hard at a faster speed, the trainer may stay below that speed more often to make the runner more comfortable; and if a certain speed feels very easy, the trainer may ramp up the pace.

VO2 Max Testing at NIFS

Korr CardioCoach metabolic system VO2 max testing is offered here at the National Institute for Fitness and Sport. Connect with a trainer at the track desk if you have any interest or questions. VO2 max testing is a great way to gauge your endurance level going into marathon training, and a great way to pace yourself in a race by knowing where you are at physiologically at different workloads. Knowing your VO2 max as a runner is like how a powerlifter knows what the maximum amount of weight they can bench is. If you don’t have a benchmark going into a competition, you run the risk of over- or under-shooting and not performing as well. You don’t necessarily have to partake in a full VO2 max test if you are concerned about going to volitional fatigue. There are submaximal tests and estimation equations that can be utilized to get a rough estimate of your VO2 max. See a NIFS staff member with any questions you have pertaining to a VO2 max test or to schedule your test today.

For whatever reason, there seems to be this notion in the fitness industry that if the workout doesn’t leave you on the ground gasping for air, it really wasn’t a good one. Or maybe that you didn’t work hard enough because you didn’t go running to the nearest trash can by the end. This could not be further from the truth; but unfortunately this way of thinking still seems to run rampant.

Not Every Workout Has to Be a Gut-Buster

One of my favorite quotes when it comes to strength and conditioning comes from Yuri Verkhoshansky, Russian professor, coach, and author who is credited as being the father of plyometrics. He suggests that “any idiot can make another idiot tired.” Now, I’m not calling anyone out. But this brings up a fantastic and often forgotten premise: that we should not judge the quality of a training session simply by how exhausted we feel.

Yes, we should challenge ourselves. Yes, there should be times when a workout feels more difficult. But here’s the key: not every workout should feel like a gut-busting knock-down, drag-out fight to the finish. If it does, it might be time to reevaluate.

A Quick Exercise Physiology Lesson: The Aerobic System

Our bodies rely on three energy systems to get us through everything from a tough workout session to washing the dishes, as well as basic organ function around the clock. They are all operating in some capacity all of the time, just in varying degrees based on the activity we’re doing. It’s not like a light switch, just on/off. Here are our players:

• The ATP-PCr or phosphagen system (immediate)
• The anaerobic or lactic system (short term; remember glycolysis?)
• The aerobic system (long term)

Now, this isn’t intended to be a full-blown Bill Nye-esque science lesson. But I do want to focus on one of those energy systems for just a moment because it plays a massive role in how we are able to recover from task to task. And that is the aerobic system. It has the capacity to produce a great deal of energy, ATP—our body’s form of energy currency. The only problem is that is takes a little while longer to do compared to the other two. As a result, the aerobic system is responsible for replenishing and producing energy during rest periods or downtime between bouts of high-intensity exercise.

Much like any facet of fitness, this system can be trained directly. It typically comes in the form of slightly lower-intensity exercise (examples to come in a future post). So, while the exercise session might not feel like a back-breaker, the benefits that arise from it can come back twofold when looking at future training sessions. Essentially, what you’re doing when you are working on bolstering your aerobic system is building a bigger, more efficient engine.

Reap the Benefits of Faster Recovery

So, those high-intensity classes you take a couple times per week? Think about being able to sustain the same power and strength from round to round because you can recover more effectively during your rest periods. Or maybe you like to hop under the bar for some strength training in the form of squat or bench press. Well imagine being able to hit more of those heavy singles because you recover more proficiently between sets. That’s when the aerobic system really kicks into high gear: during rest. Yes, it is always contributing to some degree when it comes to ATP production (remember energy currency?). But its benefits really come to light during the downtime.

Building your fitness profile really requires a 360-degree approach. Some sessions may focus on strength. Some sessions may focus on high-intensity training. And some should take the time to address the aerobic system. Not only do they provide the body some much-needed recovery time; these sessions can also allow you to get more out of those strength and high-intensity workouts as well.

Next time, I’ll cover specific examples of how you can train your aerobic system. Until then, stay strong, my friends!

In recent years, carbohydrates have seemingly been blamed for our health problems. Many of us now shun potatoes, rice, and even fruit in fear of the dreaded pounds that could come with eating carbohydrates. While many diets demonize carbohydrates, others preach the benefits of higher-carbohydrate diets. Through all of this confusion, I will try to set the record straight.

No single food or food group should be blamed for weight gain or credited with weight loss. Carbohydrates span a broad range of foods, from beans, fruits, and veggies to pizza, pasta, cookies, and French fries. While we hate to oversimplify the equation, weight gain does come down to calories in versus calories out. If we eat too much of anything—even fruits and veggies—we will gain weight. The caveat is that fruits and veggies are nearly impossible to eat too much of because they are rich in fiber and low in calories, while other foods can pack a calorie-dense punch in a very small serving.

How easy is it to eat an entire bag of Chex Mix while you might struggle to eat half a cup of carrots?

Carbohydrates and a Healthy Diet

Carbohydrate-rich foods form the foundation of a healthy diet. The National Academy of Sciences recommends people consume 45–65% of their daily calories from carbohydrates. In a 2,000-calorie diet, this is equivalent to 225–335 grams daily. Carbohydrates are crucial for energy production in the body for working muscles, fuel for proper mental function, supplying vitamins and minerals, as well as providing large amounts of fiber for decreasing risk of chronic disease like heart disease and cancer. Many foods contain carbohydrates: whole grains, fruits, starchy veggies, milk and dairy, pasta, beans, and refined/processed foods.

Should I Avoid Carbohydrates?

In recent years, many have found lower-carbohydrate, higher-protein diets to be beneficial in weight loss. However, the long-term effects of such a diet are not well studied. Many “low-carb” diets can lead to an increase in foods like red meats, processed meats, and saturated fat–containing foods like cheese, butter, and cream. Carbohydrate-rich foods provide numerous health benefits and you should not avoid them. Certain areas of the world called Blue Zones offer an interesting look into the benefits of a higher-carbohydrate diet. They have not only the highest rates of longevity but also very low rates of chronic disease. Blue Zone populations consume 95% of their calories from vegetables, fruits, grains, and legumes and eat meat sparingly.

“Good” Versus “Bad” Carbohydrates

But it is important to think about the types of carbohydrates you are consuming. Unrefined carbohydrates are unprocessed, whole foods that are high in fiber (and many other nutrients) and digest more slowly. Unprocessed, whole-food carbohydrates help you feel fuller and get you through the day feeling less hungry. Processed carbohydrates lack fiber and may have added oils and sugar—they can leave you feeling low on energy as they are quickly digested and burned for fuel. Unprocessed carbs are key to long-term health and can help with weight control. They also guard against type 2 diabetes, cancer, and cardiovascular problems. Try to limit most processed carbohydrates because they are low in nutrients and high in calories.

Unprocessed Carbohydrates

• Oats
• Brown rice
• Fruit
• Beans
• Whole grains
• Vegetables

Processed Carbohydrates

• Soda
• Baked treats
• Packaged sweets/snack foods
• Fruit juice
• Breakfast cereal

Did you now that in 1915 the average American consumed 17.5 pounds of added sugar in a year? As of 2011, the average American consumed over 150 pounds of sugar annually!

In summary, carbohydrates should be welcomed to not only help with weight management but also prevent disease. Make most of your carbohydrates whole, unprocessed foods for a balanced, healthy diet while enjoying the processed/refined carbohydrate foods in moderation.

Start your day off right by nailing breakfast with a healthy, nutrient-rich meal. Breakfast helps kickstart your metabolism and burn more calories throughout the day. Eating breakfast tells your body there are plenty of calories to be had throughout the day. When you skip breakfast, the message is clear: conserve calories rather than burn them. Those who skip breakfast may eat fewer calories but still tend to have higher BMI.

Other studies have found more benefits to breakfast, including:

• Consuming less fat.
• Meeting fruit and veggie recommendations.
• Higher daily calcium intake.
• Higher daily fiber intake.
• Better memory and improved attention span.

Skipping breakfast leads to:

• Higher likelihood of being overweight.
• Less likely to meet recommendations for fruit and veggie consumption.
• More likely to consume unhealthy snacks.

So, a Pop-Tart a Day Will Mean Improved Health?

Not quite! Try to choose a breakfast that is unrefined/unprocessed and moderate in calories, high in fiber (5 grams or more), nutrient-dense, and has some protein (about 10–15 grams to help with keeping you full).

A sugary breakfast option like Pop-Tarts, donuts, or Cinnamon Toast Crunch lacks the fiber to keep you full throughout the morning and can pack a punch in terms of calories. Have you checked the serving size on the back of a cereal box? Unfortunately, people usually go way over that ¾ cup recommendation, and a bowl of cereal can sometimes max out at roughly 2,000 calories. A 16-oz. bowl holds about 6.5 times the serving size of Frosted Flakes. Add the milk and that can get you even closer to 2,800 calories! This can equate to relatively quick weight gain, especially if you find you are hungry again by 10am.

Some Good Breakfast Options

So what are some good choices for breakfast?

• Oatmeal with fresh fruit and nuts
• Whole-grain toast with avocado
• Fruit smoothie with protein powder or nut butter
• Egg scramble (or try tofu!) loaded with veggies
• Whole-grain bagel with nut butter and slices of banana
• Greek yogurt with fruit
• Piece of fruit and handful of almonds
• Apple slices with peanut butter
• Overnight oats
• High-fiber cereal with fruit and low-fat milk or plant milk (try Barbara’s, Nature’s Path, or Kashi)
• KIND Bars, GoMacro bars, RXBars (high protein, low sugar)

Here are a few recipes for healthy breakfasts you can make quickly and take with you on a busy morning.

Like most people, I’m busy: full-time job, kids, a house… and in my “spare time,” I’m a high school tennis coach and play a lot of tennis. A few years back I started having issues with exhaustion (go figure). Right around 4pm I would just be overcome with complete, hit-the-couch, exhaustion. The only way to make it through the rest of my busy day seemed to be one more caffeinated drink.

I’m not a coffee drinker, so my drink of choice to get going in the morning was an AdvoCare energy drink called Spark®. I loved my Spark®, probably as much as most people love their coffee. I personally had no issue with using stimulants to keep me going through my day, but that changed one day recently on my drive home from work.

The Impact of Stimulants on the Brain

While listening to Fresh Air on NPR, I heard a discussion on sleep with sleep scientist Matthew Walker. Part of the talk discussed the effects of caffeine on the brain and how it alters the natural functions of the brain, including the buildup of adenosine. Adenosine is a chemical in the brain that builds up throughout the day, edging you to sleep. Caffeine comes into the brain and masks the effects of adenosine on the brain so that you are fully awake. One problem is that adenosine continues to build up, so when the caffeine wears off, you have additional levels of adenosine in your brain. This creates the effect we know as caffeine crash.

This made me think about what I had been putting in my body and the fact that I was using caffeine to mask the real issue I was having: not enough sleep. This one show made me rethink how I was treating my brain and how I had allowed caffeine to creep solidly into my everyday habits. It also reminded me that I was disregarding the need for one of the most critical things needed by the body and brain, sleep.

Giving Up Stimulants and Getting More Rest

Three months ago, I quit caffeine drinks cold turkey: no Spark®, colas, or energy drinks. In addition, I put the theory to the test and began carving out eight hours for sleeping each night. At first it took a bit more structuring, but now I don’t allow myself not to get a full night’s rest.

The results have been pretty amazing to me. In the first few weeks after quitting caffeine, I can honestly say that I was not tired. My energy levels were good all day and I was tired at the right time in the evenings, leading up to a decent bedtime and better sleep. I have also lost the cravings I had for those caffeinated drinks, which is an added bonus since I didn't have to worry about ordering more Spark® each month.

Many will tell you there are pros and cons to quitting caffeine but for me its one of the best things I have done for my health recently. Cutting caffeine has allowed my brain to function the way it was meant to, without a stimulate to interfere. For me, that is a step in the right direction.

Since the dawn of time (I’ve always wanted to start a sentence like that), humans have slept for a little while, and then were awakened by something or someone that told them it was time to start the day. We know now the huge roles that sleep plays in so many aspects of our health:

• Physical recovery
• Healthy hormonal environment
• Stress regulator
• Cognitive retention and memory
• Appetite regulation

The Science Behind Sleeping and Waking

We have circadian rhythms that act as an internal clock of sorts, which usually run on roughly a 24-hour cycle. Researchers have identified that circadian rhythms can influence our sleep-wake cycle, and abnormal circadian rhythms have been associated with obesity, diabetes, depression, and other disorders. 

Why am I telling you all this? Well, your circadian rhythms are produced by natural factors in your body, but can also be influenced by the environment. Light is the major cue influencing the rhythms that turn on or turn off genes that control your internal master clock. Having a normal, healthy circadian rhythm can be the difference between waking up ready to conquer the day or having to hit the snooze button a hundred times. 

Using Light to Wake Up

So if light is one of our biggest cues to maintain a healthy circadian rhythm, use it! My beautiful wife gave me a gift on my birthday recently that I have found to be so helpful in waking up and feeling rested and ready to go. It’s a Phillips Wake-up Light, and it allows you to wake up naturally with the warm glow of the sun-like light that radiates from this futuristic-looking alarm clock. I absolutely love it! 

The light will begin to glow anywhere from 20 to 60 minutes prior to your set time to wake up (how hard you sleep will determine how much time you should have the light begin glowing). The light begins a reddish color to simulate the sun rising, and gradually becomes brighter and brighter until you wake up and turn it off. And if you were to sleep through the 20-minute light glow, you would be awakened by birds chirping. 

I have definitely noticed a difference in my energy level when I wake up these days, as well as my attitude and mindset heading into a tough day. I was experiencing some not-so-positive reactions to my alarm clock, which really set me up for rough start to the day, which in turn affected me throughout the entire day. Now that I am waking up naturally, and not shot out of a cannon to the sound of the buzzer, the morning is much more pleasant and meaningful.

Other Benefits of Waking Up Naturally

Some other fantastic benefits of waking up naturally include the following:

• Improved insulin regulation. This is important in managing body weight and body composition.
• Improved parasympathetic response. Instead of waking up in a “fight or flight” sympathetic response, which will result in elevated resting heart rates affecting many other aspects of health, we stay in a calmer state, allowing the internal environment to adjust appropriately to stress.
• Decreased muscle tone. I am not talking about losing muscle tissue. I am referring to “turning down” the tone of certain muscle groups that can be putting you into less-than-optimal body positions. For example (and one of the most common), toned-up lats will cause you to be in extension, which can lead to lower back pain. When we are calmer, and not so jacked up, we can allow the body to tone down when needed to improve positioning and movement patterns.
• Better mood! Life is way too short to be miffed all the time, and it just causes problems in so many facets of our lives. Most of this bad mood is communicated nonverbally, which in most cases is so much stronger than anything you could say. Take my word for it, be happy in both your message and how you deliver it. This can be greatly improved if you feel good and not groggy, which started hours earlier with the whack of the snooze button. 

I highly recommend implementing some sort of a natural wake-up process that works for you. Most of us have smartphones. There are plenty of apps out there that can do the same thing as the wake-up light I describe above. Many of the newer fitness trackers such as a FitBit can also be set to gradually wake you up. Give it a try and let me know what you think, but have a back-up just in case it doesn’t work for you right away—don’t be late to work on my account!
