Read moreCleaning Up a Diet Without Restrictions
I catch myself saying the words: “new year, new me” every single January for years, and I get a little annoyed halfway through the month. It’s not that I feel there is anything wrong with the saying—I just think I don’t give myself credit for how good I actually am with most aspects of my life, particularly my health. I run six days a week, lift weights, eat pretty healthy, drink lots of water, stay away from smoking and heavy alcohol, and I wear sunscreen everyday. Besides working on time management this year, which has been a true failure for me since I became self-employed (this will be a separate blog post very soon!), I’ve been wanting to focus on specific aspects of my diet that I have been ignoring for years. I say out loud it is mostly about my acne-prone skin issues, but there are so many other symptoms that I feel are linked to annoying food sensitivities that I have been refusing to address.
As For These “Symptoms”…
I don’t feel I have experienced many symptoms that affect my function on a daily basis, which is the reason why I’ve just ignored them for so long. The only thing that’s really bothered me during my adult life is my acne and melasma, which I feel and have been told is primarily hormone-related. I also regularly get bloating and less than regular digestive issues. Increasing fatigue over the last couple of years has more recently been my main concern, since that specifically has been affecting my strength, running, and daily concentration on my work. Just a few months ago I was diagnosed with borderline hypothyroidism, which is definitely related to these symptoms, but diet can play a large role in managing the condition and keeping my symptoms at bay. My goal is to try and delay the need for long term hormone replacement for this health problem.
Restrictive is NOT the Way to Go…
At least not for me. Last year I went ahead and took advantage of a big discount that was going on for Everlywell—the at-home lab test. I was interested in seeing what food sensitivities I actually have based off of their kit. I know I shouldn’t take this as 100% accurate, especially after doing my own research and reading reviews about the discrepancies between these" “at-home” tests and real allergy testing. I kept in mind that this option was not testing allergies at all—just sensitivities I may have when consuming certain foods. I honestly thought my results would come out to maybe a couple at the most and it was a list of 22 foods! Now, one of the reviews I received from a handful of Instagram followers is that the case for some of these is that the test picks up foods I regularly eat, rather than something in my blood telling me I’m actually sensitive. Therefore I took the results with a grain of salt.
This long list of foods includes almond, wheat, chicken, eggs, garlic, potato, and oats, among others. Surprisingly the only dairy foods that were on the list were mozzarella and yogurt. For a few years now I have tried to stay away from dairy products after the recommendation from a dermatologist, and it made a big difference in my skin and digestive issues. I totally thought this would be number 1 on the list of food sensitivities! Regardless, the list was overwhelming for me so I did not do what was suggested which is an elimination diet. With that many foods on the list, it felt restrictive to me, and when I’ve restricted food groups in the past, it only caused me to have intense cravings and then binge eat. I feel I never minded restricting dairy all this time because I really didn’t care for it to begin with. I don’t like cheese at all, can live without yogurt, have never really been an ice cream fan, and with any recipe that called for milk I was perfectly fine using the alternatives.
Ticking Off New Year’s Resolutions
Okay, so one priority for me as far as goals go for this year is to learn something new every day. So far, I’ve been successful, and one thing I’ve learned this year is about what in milk is really the culprit of digestive issues. It’s the protein! I thought it was the added hormones some farmers use on cows or the lactose, but it’s actually specifically the A1 protein. My parents are very obsessed with A2 milk, which is made from cows that only produce the A2 protein. Once I learned all about this I decided to give this brand a try. As many of you saw on my Instagram feed, I jumped on board and took a challenge this month to switch out my milk, and I’ve been so happy about the results. No bloating, no stomach aches, and NO ACNE! I highly recommend this switch if you are sensitive to regular milk! Oh yea—and right now you can enter to win free a2 Milk for a year and a Peloton Bike + 1 year membership. Click here!
What About the Rest of My Diet?
Well, this post is the start of my goal—attempting to dial in to my current way of eating and pinpoint what is playing a role in my fatigue. I know I can be better about limiting my frozen food lunches and packaged snacks I have been eating regularly for the sake of saving time, so this will be the first thing I tackle (as I write this, I am eating plant-based air-fried chicken tenders). I also need to get back to a regular eating schedule—this will help with energy levels. I tend to get bogged down by projects and forget to eat. This will require me to make time for meal planning and being more creative with quick snack options for my work day.
Tackling this goal in 3, 2, 1… I’ll keep you all posted! Make sure to follow along on Instagram for the latest updates.
Staying Happy & Nourished During Isolation
featuring Atkins
Sponsored by Atkins. All opinions are my own.
Working from home has its positives—you have a flexible schedule, can spend the entire day in pajamas, and can usually pause your work to squeeze in an errand or workout without a problem. It also has its downsides, though, especially when you are not only stuck at home during the workday, but also at night and the weekends. This is the case for everyone right now during the COVID-19 crisis we are dealing with. It was hard to get excited about working from home a couple of months ago at the start of this pandemic since the death toll was continuously rising every day. At the same time many people found it hard to stay consistent with a schedule being at home almost 24/7.
For me, it’s been a good eye-opener to be grateful for my health and the security of my family. I’m even more thankful now for the ability to run during this time, since gyms and other fitness classes have been canceled. Running brings me joy, but in order to run well and improve my performance in the sport, I need to eat well. Most of us know this does not come easy when you are home all day! I have a major sweet tooth and I’m living with family right now who love to keep desserts in the house, so you can imagine how hard it’s been to stay away from too many treats! Luckily I have gotten into the habit of managing my sweet tooth while still staying satisfied and nourished for my running goals.
Protein-Focused
Athletes know how important it is to get enough protein. It’s the nutrient that plays a significant role in muscle repair. Protein keeps you feeling full, too. It’s a good idea to include a serving at every meal, so you are less likely to overeat. The most important time to have protein is immediately after exercise. Hard runs call for my favorite optimal protein meal—a dark chocolate peanut butter smoothie! It’s a quick and easy recipe using my go-to shake from Atkins. The Atkins Dark Chocolate Royale is my favorite flavor but I’ve also made this smoothie with the Atkins Mocha Latte and Creamy Vanilla, and it’s just as satisfying! It just takes a handful of ingredients and a few minutes so you don’t have an excuse to skip out on your post-workout refueling!
How to Make the Dark Chocolate Peanut Butter Smoothie
Ingredients:
· 1 Atkins Dark Chocolate Royale Shake
· ½ ripe avocado
· 1 Tbsp creamy peanut butter
· 1 Tsp cocoa powder
· 1 Tbsp chia seeds
Mix all ingredient together in a high-speed blender with a few ice cubes, pour, and enjoy!
It doesn’t get easier than that! Most people find the use of an avocado in a smoothie to be weird, but since it’s relatively flavorless, it’s just meant to add thickness and creaminess. It basically replaces the use of a banana and makes it a perfect option if you are looking for a low sugar recipe. That’s the best part about this smoothie recipe—it’s low carb, so you can have it at any time of the day. It’s also a great option for those of us that crave something sweet late at night. Atkins shakes also have just the right balance of healthy fats, fiber, and key protein to keep you satisfied and your energy levels steady. I’ve been enjoying these shakes as part of my afternoon snack, but ever since adding them into my post-workout smoothie, I’m enjoying them even more!
Quarantine Happy
The majority of people sitting at home are struggling to stay content with their day-to-day lives. You hear all over social media how this is a great time to find a hobby at home or start a new venture, but when you haven’t been succeeding at productivity, it brings on a sense of discouragement. This should not be the case! It is actually OKAY to not be coming out of this pandemic with a new sense of self. I believe we should be doing what we want whether we are in quarantine or not—if you want to just sit around and relax and not worry about productivity, that’s just fine!
Rather than taking up a new hobby or starting a new project, I’m focusing on the aspects of my life I actually enjoy and do more of them with the extra time I have. This means I am following a more structured running program, getting in and sharing the workouts I love with my community, and cooking more every day. I can’t come up with any excuses to get out of my current and regular health routine, and I am happy to say Atkins truly has made meal prep, snacking, and refueling after workouts much easier and more enjoyable during this stressful time.
Cheat Meals: They May Not Be So Bad After All
Consuming a diet that is 100% healthy food is not the easiest way to live. Although some people do just fine cutting out all of the “bad” foods from their diets, the majority have a hard time. Daily stress surges, cravings kick in, and the temptation of indulging in a whole pizza pie or bag of cookies becomes impossible to dodge. It is known that one of the best ways to even start a diet is not necessarily to go cold-turkey and cut everything out at once, but rather in a gradual manner over the course of weeks. It has been questioned whether including a cheat meal in a diet is harmful or not, but recent research has stated that it can be helpful in order to stick to your strict eating plan as long as you do it the right way.
Not a Cheat “Day”
It is important to note that cheat meals are only helpful to a diet if they are left as that— meals. Often times dieters use an entire day to indulge at every meal and this can wreak havoc on your weight loss goals. Although a cheat meal can rack up to a few thousand calories, it will not undo any of your dieting from earlier in the week. But an entire day of feasting will double or triple those few thousand calories. Having more than one cheat meal may make it hard to get back into your normal healthy eating habits.
Motivation
A cheat meal serves many purposes. Many times it is a source of motivation for someone on a strict diet. Eating plain chicken and vegetables day in and day out can get boring, but knowing that you have a night of burgers and fries or ice cream waiting for you at the end of the week can motivate you to keep strict. Cutting calories when trying to lose weight can lower overall energy levels, especially within the first few weeks of beginning a diet. One cheat meal will actually provide much needed energy to maintain a balance in the body.
Increased Metabolism
Consistently consuming a diet too low in calories will eventually slow down your metabolism, leading to slower weight loss. A cheat meal provides a boost in overall calorie consumption, which will cause a “shock” to the body’s digestion. This will increase your metabolism and help you burn more calories on a daily basis. It is hard to believe, but yes, a cheat meal will actually help you lose weight! There are diet plans that will fluctuate the number of calories you consume each day for this same reason.
The reason this works is because the seldom ‘jump’ in calorie consumption on one day will help regulate the hormones in charge of hunger and satiety. When on a weight loss diet we should be eating fewer calories than we burn, but over time our bodies end up adjusting to this new calorie amount. That is when we hit a plateau and stop losing weight. Adding in one day of a bit higher calories keeps the body in a burning state, helping with further weight loss. Leptin, the hormone in charge of controlling the sensation of feeling full dramatically decreases over time when on a low-calorie diet. Ghrelin, on the other hand, is the hormone that is responsible for telling you that you are hungry and will increase over time on a low-calorie diet. In order to keep burning calories, one should strive to keep the leptin hormone elevated and ghrelin on the lower end. A cheat meal assists with this regulation and aides in continued weight loss.
Keep the Balance
When choosing your cheat meal, it is best to not have the ‘all or nothing’ mentality. If you are going to splurge, make sure it is on something you actually care to eat. Do not waste calories on something that is not that satisfying to you. For example, when going to a restaurant and planning on having a big bowl of creamy pasta for dinner, stick to just that. Your date or party may order a few appetizers that are far from being on the list of your favorite foods, so do not even grab a bite! You will enjoy your pasta dish much more if you steer clear from giving into calories you did not care for in the first place.
The best way to indulge in what you truly enjoy as a cheat meal, but not go overboard, is to cook at home. If you want pizza, make a homemade one—crust and all. This will ensure you know exactly what ingredients are going into every bite. If what you crave are a burger and fries, make your own at home using cooking spray rather than oil, whole grain burgers buns, and baked fries. You will most likely save about half the calories than eating this same meal at a restaurant or fast food joint. It is best to learn the most you can about healthier substitutions. You will be surprised as to how much you can still satisfy your cravings and not feel guilty when opting for healthier alternatives to those ‘bad’ foods.

How Many Calories Do Runners Really Need?
Several factors go into being able to improve your performance as a runner. Consistent training with the right mix of speed work, long runs, and easy runs are at the top of the list. Rest and cross training must also be incorporated to recover properly and be prepared for the hard sessions to come. Nutrition plays a large role in performance, as it is what gives us the energy we need to actually perform and to do it well. Consuming the proper amount of carbohydrates and proteins is the key to sustaining energy levels while making sure to include other key nutrients like iron and vitamins.
You may have been in the situation where you do well during training for a bit but frequently struggle to hit several workouts in a row. This is usually a sign that you are not eating enough. As volume and intensity increases during training cycles, the number of calories your body requires increases as well. Even if you are on top of your nutrition game, it is easy to not meet your recommended calorie intake. Not eating enough calories can leave you fatigued on every run and increase your injury risk. But what is the right amount?
Calorie Intake
The right amount of calories a runner requires will depend on age, sex, weight, and activity level. This means it may be necessary to consume a fluctuating amount each day of the week since the intensity and length of runs and other workouts vary. The recommended daily calorie intake for a sedentary adult male ranges from 2200 to 2600 calories. For females, the range is 1800 to 2000 calories. Therefore some distance runners may need close to 3000 or more calories most days of the week to maintain their weight and energy levels. This may seem like too much, especially to women, but it is what is necessary if you want to perform your best and not risk getting injured.
Weight Loss & Training
If you currently are overweight or obese, then a lower calorie intake is ideal until you reach your goal weight. This should be done carefully, as cutting calories too low can result in limited energy. This will only lead to having to skip workouts and not be able to run your hardest. Having too little calories may also lead to muscle loss, which is what powers us through our workouts. Therefore if weight loss is a goal when training for a race, then it should be done gradually. Unfortunately, it is safest to plan an extremely slow weight loss of about a half pound per week.
Calorie Requirements Equation
Although calorie calculators you find online are used to get an estimate of the number of calories you need, it is usually in the ballpark of the right amount. The Harris-Benedict equation is a popular formula used to estimate your needs and takes into account your current activity level.
BMR for Men: (10 x weight in kg) + (6.25 x height in cm) – (5 x age in years) + 5
BMR for Women: (10 x weight in kg) + (6.25 x height in cm) – (5 x age in years) – 161
BMR is your basal metabolic rate, which is the number of calories your body requires in order to function properly. Once you calculate your BMR with this formula, you can multiply by the different values according to daily activity level.
For men and women:
Sedentary/little to no extra activity: BMR x 1.2
Light exercise 1-3x/week: BMR x 1.375
Moderate activity 3-5 days/week: BMR x 1.55
Very active 6-7 days/week: BMR x 1.725
Hard exercise/physical job (2x/day training): BMR x 1.9
This method is a good way to determine how many calories you should have on each training day, since some runners train twice a day a few times per week, but take a full rest day as well. Calorie requirements will be very different for each of these days.
Even with the above formula, the calorie requirement calculation can be wrong—either too high or too low. Everybody is different and some runners burn more calories per hour than others. Fitness levels, genetics, and present medical conditions can impact your calorie-burning rate. A more accurate test is one where you sit for ten minutes with a mask over your face and your breathing is measured to determine how much oxygen you use at rest. Whether you use this method or the formula above, many times it is all about trial and error. It is best for runners to eat more than they think they need at first and see how their body responds rather than under eating to see if it is good enough. You do not want to risk getting injured or wasting too many weeks not making progress due to not eating enough.
Types of Calories
Once you understand your individual daily calorie requirements, then it is important to fuel your body with the right types of calories. Limiting “empty calories” is key as these are considered calories with no nutritional value. Most packaged snacks, candy, soda, and chips are in this category. Runners should focus on getting the majority of their calories, at least 60%, from high-quality carbohydrates in order to supply the muscles with enough glycogen. The other 40% can be divided evenly between lean proteins and healthy fats. Proper fueling and hydration practices are necessary for performance improvement, injury prevention, and for an overall healthy body.

Depletion Running: Should You Try It?
Breakfast is the most important meal of the day, right? Yes, of course, but there are times when it may be a good idea to skip it, or at least wait a little later in the morning to have it. Runners know how important it is to fuel their bodies for their runs, especially for those hard and long workouts. It is always advised to have the proper amount of calories and carbohydrates before long runs and races in order to supply the muscles with the glycogen it requires to be able to push through the run. During half and full marathons, as well as ultra races, mid-run fuel is also important to keep those energy stores as high as possible to keep us going. It is during the end of races that we feel the depletion in our bodies from lack of fuel, which creates that ‘zombie-like’ final 10K of the marathon, otherwise known as “bonking”.
What is a Depletion Run?
The concept of depletion runs has grown to be quite popular, especially in the elite world. This is basically when runs are performed in a starved state. This will usually be in the morning after a full night’s sleep when glycogen stores are at its lowest. The reason some athletes do this is to train their bodies to use their fat stores so that come race day, they are able to last longer when energy is low. Many runners swear by this training method but also report it to be uncomfortable and make their runs much harder to get through. If you are willing to go through several runs feeling low on energy in hopes to not hit “the wall” during your marathon, then it may be worth a try.
The Science
When you run without fueling up beforehand, the body will rely on fat stores for energy. This energy, though, will not give you the same feel as the energy from glycogen, which we get from the carbohydrates we ingest. What this will train the body to do is use fat stores during as much of a race as possible and save the glycogen stores for when we really need it—the end of the race. The important thing to remember in order to keep from using any stored glycogen for the first half of your training run is to keep a conversational pace throughout the entire run. Any faster, and you will risk dipping into the glycogen you need to save.
The Method
It is important to have a decently large dinner the night before your depletion run, so that your body can store as much fat as possible overnight. The morning of your run, simply do not ingest anything except for water (although some runners also deplete themselves of hydration, which is a dangerous mistake). For long runs, where you would normally refuel mid-run with gels or chews, you will skip this part on a depletion run. Immediately after completing this run, it is extremely important to refuel with plenty of carbohydrates—at least 50 grams and around 25 grams of protein. An hour later you should have another carbohydrate-rich meal.
When to Practice Depletion
This type of training should not be done with every training run. It is beneficial to perform depletion runs 3 or 4 times for long runs early on in your training cycle when you do not have to worry about practicing your race fueling strategy. Short and easy runs are good times to practice depletion as well, but mostly for the sake of teaching yourself to get used to the ‘not eating’ part. Never try this for speed work or marathon paced runs because these harder workouts require glycogen in order to be able to be successful. If you attempt to run on an empty stomach for hard workouts you will not be able to push yourself as hard and therefore limit any performance gains.
Morning runs are the easiest times to practice depletion since you have not used much energy and it is when you will feel the least hungry. Making sure to hydrate the night before and the morning of will help with any hunger and keep you from getting dehydrated during your run. Only experienced long-distance runners should try a depletion run. If you are not so experienced and want to give it a go, first try cutting your regular pre-run fuel intake little by little over the course of weeks.
Depletion runs are not for everyone, but if you normally feel the ‘bonk’ at the end of your races, it MAY BE worth a try. If you are not a fan of feeling hungry or weak on any type of run, then it most likely isn’t a training technique you should try. This method of training will not cause weight loss or make you a faster runner. It is simply to help with endurance, although there are other, more tolerable, ways to improve endurance. Training the body to rely on fat stores and save glycogen for those last six miles, will allow you to run longer at your goal pace.

The Role of Glutamine in Recovery
Whether you are an elite athlete or a recreational runner training for long distances, you are at risk for developing overtraining syndrome and other ailments. Marathon training requires us to engage in multiple strenuous training sessions several days out of the week. More advanced runners train somewhat intensely every day! Prolonged and intense exercise can increase the risk of muscle tissue damage, inflammation, cardiac dysfunction, decreased immune function, and overuse injuries. PHEW! That’s quite a list of negatives, but don’t be fooled—there is a way to avoid all of these!
When deciding what type of marathon training plan is right for you, it is important to know that all plans can be modified based on your needs. Some athletes require more rest and recovery days than others. There is a reason that these easy days are scattered throughout the training weeks in every plan. It is meant to decrease the risk of developing the negative side effects of too much running.
There are important vitamins and nutrients athletes specifically need in order to stay healthy. Although a good balanced diet, preferably higher in quality calories, may be enough to obtain all of these essential nutrients, sometimes supplementation is necessary. Getting in everything we need for a balanced diet is difficult to do day in and day out, especially if you have a busy schedule to begin with. Many athletes supplement their diets with extra protein, usually in the form of powder. The reason for this is that protein is crucially important for the health of muscles, bones, skin, cartilage, and blood in the body. When deciding which protein powder to use, it is best to choose one that includes the important amino acids, which are the building blocks of the protein we need in order to function.
Glutamine
One extremely essential amino acid that gets depleted with hard training is glutamine. The depletion is said to likely be from the demand for glutamine from different organs exceeding the supply in the body after exercise. The role of this essential amino acid in the body is to assist with protein synthesis to build stronger muscles, support the immune system, and for the enhancement of hydration in the body. After strenuous exercise, the depletion of glutamine can last up to six days, which can greatly affect the recovery process of muscle damage. The low state of this essential amino acid is also what causes athletes to be more susceptible to illness, such as colds and the flu, following hard training. Glutamine may also be depleted with other conditions such as trauma, burns, muscular dystrophy, and any other conditions causing stress in the body.
Muscle Repair
Muscle tissue damage is almost inevitable in athletes. The breakdown of muscle, causing tiny tears, is what builds strength. But this strength is only built during the recovery and healing process. This means that your muscles aren’t actually getting bigger and stronger while you are weight lifting—it all happens when you begin your rest period. Of course, nutrition will also play an important role in these strength gains. It is always a good idea to eat after a workout, especially after a strenuous run. A carbohydrate and protein-rich meal or snack is ideal, since this will help speed up the recovery process. As mentioned above, choosing a protein powder that includes the essential amino acids as part of a recovery shake is a good option to replenish the possibly lost glutamine. Glutamine alone also comes in the form of capsules, so this may be a quicker option for some athletes.
Immune Function
Glutamine is essential to immune function as it assists with lymphocyte proliferation and the production of cytokines. What does this mean? Well, lymphocyte proliferation is basically cell production and cytokines are molecules the immune system needs in order to communicate when there is infection, inflammation, or trauma. Without these processes, immunity is weak and cannot properly fight against bacteria. Studies have shown that the inclusion of glutamine following surgery, medical procedures, and trauma, especially in patients with a compromised immune system, resulted in lower levels of infection and shorter hospital stays. In the case of endurance athletes, studies have concluded that there have been less episodes of illness following strenuous training or races with the intake of a glutamine supplement.
Muscle Hydration
Glutamine assists in the absorption of water and other nutrients to keep our muscle tissues hydrated properly. Prolonged and intense exercise causes extreme stress and dehydration throughout the body. Glutamine supplementation has been shown to improve the hydration process by way of enhancing electrolyte and fluid absorption in the muscles. It may be beneficial to opt for electrolyte drinks that contain this nutrient and other branched-chain amino acids, usually labeled “BCAAs”.
If you are a runner looking to increase your training time and improve your performance, it is extremely important to pay attention to your diet. Many people have the thought that since they are exercising so much they can eat whatever they want and not worry about nutrition. Yes, the body will burn a load of calories with the hard workouts, but it will only impede strength gains and performance improvements if the body is not taking in the nutrients and vitamins it needs to repair and build. With all of the calories burned, essential nutrition gets depleted as well. This will only lead to fatigue, illness, and/or injury. The best way to get as many of these important nutrients from your diet is to make sure you are getting in enough quality carbs, protein, and fats from nutrient-rich foods such as veggies, fruits, and whole grains.

Beta-alanine & Exercise Performance
Runners, like many other athletes, are constantly looking for safe ways to improve their running performance. Whether it be training in certain environmental conditions like in the heat or at altitude, or changing their fueling methods, there are many strategies one can use to get faster and last longer. The key to seriously improve performance is to understand where you are lacking in the first place. Is it too little muscular strength that is holding you back from running with good form? Or maybe you are actually pretty strong but endurance is what is weak. In many cases performance is hindered by poor nutrition, especially before and during exercise. For some runs it may be just fine to go out on an empty stomach but if you want to run hard and for a long period of time fueling the body efficiently is important.
Supplementation
It is common for athletes to supplement their diets with nutrients they may be missing out on in their regular meals. Runners supplement with electrolytes and other vitamins that are important for proper organ function and recovery from training. Protein powders are probably the most common supplement athletes consume, as it is essential for muscle repair and growth. The building blocks of protein, amino acids, are important in the diets of athletes since during hard exercise muscle fibers go through microscopic tears and require these essential amino acids for the repairing process.
Beta-Alanine
One amino acid that is actually considered a non-essential amino acid, called beta-alanine, is a commonly used supplement in the sports world. The reason it is considered a non-essential amino acid is because it is not involved in protein synthesis, as are the others. Beta-alanine produces carnosine, a substance that is stored in the muscles and reduces lactic acid accumulation. This lactic acid buildup is produced in the muscles during exercise and is the reason why our bodies require recovery time in order to be ready for another session. If less lactic acid is building up in the first place than recovery time will be shortened. This is the main reason why beta-alanine is being used to improve performance.
*exercise image
During lactic acid accumulation, excess hydrogen ions are produced in the muscles, causing a drop in pH levels—meaning they are now in a more acidic state. This acidity blocks glucose breakdown, which is normally what fuels our muscles, causing less muscle contraction, and eventually fatigue. The carnosine produced by beta-alanine is what maintains a normal pH level in the muscles during this process, therefore lowering the risk of fatigue. This benefit of increased time to exhaustion helps runners and other endurance athletes last longer.
How Does Beta-alanine Help Marathoners?
Studies have shown that these benefits are more evident in short bouts of high intensity exercise lasting between one and several minutes. This means speed session consisting of 400m to mile repeats can be greatly improved with the use of beta-alanine supplementation. Although marathon running is commonly looked at as a low to moderate intensity exercise, the fact that you have to run at a fast goal pace for several hours requires specific training at significantly high intensity. This is where those short bouts of intervals come into play for marathon runners. Strengthening those fast twitch muscle fibers through speed sessions that can benefit from beta-alanine supplementation will lead to maintaining that goal pace you desire on race day.
Diet, Supplementation & Dosage
Most people who regularly eat animal protein get a sufficient amount of beta-alanine. Beef, pork, chicken, and fish are the main food sources of this amino acid. Regular servings of these proteins will contain between 50 to 250mg of beta-alanine. Most research advises to have between 2 and 5 grams per day to reap the benefits of carnosine production. Over the course of 4 weeks, carnosine concentration can increase by up to 40-60%. Combining the supplementation with a meal has been shown to enhance the production further. After one month of supplementing with this amount, the dosage is then lowered to half. Beta-alanine does not have to be taken at a certain time in order to gain the benefit. Some athletes combine it with their pre or post-workout drinks, but it can be included with any meal.
Supplementing with beta-alanine has been shown to be safe and effective at improving endurance and decreasing muscle fatigue during exercise. One common side effect that may be experienced is paraesthesia, which is a tingling sensation usually noticed in the face, hands, and neck. This effect is usually mild, short-lived and occurs during the first few times of taking the supplement. Carnosine production decreases by 15-20% from youth to adulthood, which suggests that beta-alanine supplementation may be even more beneficial for older athletes. As with any other supplement, it is advised to talk with your medical doctor before including anything new in your diet. Although beta-alanine is safe and shown to be effective, studies have not concluded its effects on athletes with any specific medical condition.
