Running with IBS

Stomach problems are a common complaint among runners. It only makes sense since our intestines are jumping up and down for a long period of time, sometimes for hours. Unfortunately a more serious intestinal issue affects a smaller percentage of runners and can interfere with daily training and racing. Irritable Bowl Syndrome, or IBS, is poorly understood and does not have a specific diet or medication that can cure it. This can be extremely frustrating for runners since the symptoms can get in the way of performance. The best thing one can do is to learn how to control the symptoms, but this is highly individualized.

Causes & Symptoms

The actual cause of IBS is unknown and experiences can vary from person to person. It is important for runners, and anyone else living with this condition, to understand what triggers their own symptoms and alter their lifestyle based on those factors. IBS can cause stomach and bowel sensitivity, gas, bloating, cramping, constipation, and difficulty controlling bowel movements. It is shown that different foods and psychological disturbances such as anxiety or a stressful event can cause these symptoms to heighten.

Does Running Make Things Worse?

Unfortunately yes, it does, but not in every case. If what is causing your symptoms is stress, then running can actually make it better. Studies show that exercise is a key method to relieving stress. If your IBS causes constipation rather than diarrhea, then running can also help by relaxing the intestines and promoting more regular bowel movements. For those suffering from the opposite symptoms, running will usually make it worse and cause you to have to stop mid-run for a toilet break. During exercise, especially at a higher intensity, such as running, the blood is circulated to the muscles and away from the intestines. This lack of oxygen in the area is the cause of cramping.

Controlling Symptoms

As mentioned above, runners should first figure out what triggers their symptoms if they want to be able to run without worry. A proper diet has been shown to be a critical method for controlling symptoms, but requires a great deal of trial and error. Some foods that have been shown to exacerbate symptoms are refined and processed foods (since they require more work for the body to break down), high fiber foods, dairy products, and beverages with caffeine (I know, coffee is a must for so many of us morning runners!). 

It is best to not go into a complete diet overhaul and eliminate everything. You may only have one food group that your IBS is sensitive to so avoiding everything is unnecessary. The number one place to start is by eliminating one food at a time and tracking your intake and body responses with a food diary. Cutting out dairy as a first option has been shown to have positive results in controlling symptoms. This food group is not digested very well in general in any body, so when combined with lactic acid buildup during exercise, it can disrupt the stomach for most people anyway, so it’s an even worse situation for those who suffer from IBS.

Tips for Easing Symptoms

·     Never introduce a new food/food group right before a race! Practice keeping a steady diet for at least 1-2 weeks before the event.

·     Stick with natural mid-run fuel. Gels and sports drinks can be highly concentrated and if you do not have enough water after taking them, it can cause bloating and cramping soon after.

·     Dehydration causes nausea in general so staying hydrated before, during, and after runs is important. The best approach is to practice being hydrated ALL THE TIME.

·     Avoid foods high in protein and fat before running. Actually, it is best to give at least 2 hours for a meal/snack to digest before heading out.

·     Research shows that symptoms are not only worse just after a meal, but in the morning hours as well. Opting to run later in the day may be ideal, but most races are scheduled in the early AM, so morning runs are beneficial to train the body for race day.

Once you have an idea of what your triggers are, training will be much more comfortable. For those of you who race, be careful with the “carb-loading” leading up to the event. Instead of taking in a large amount of carbs the couple of days leading to a race, it is best to start the loading about a week before and spread the quantity over the day. It may take much more time out of your schedule and weeks or even months to really figure out what is causing your symptoms, but in order to train comfortably with IBS and avoid taking medications, which are usually antidepressants, this trial and error process is worth it.

What is Macro Tracking and How Does it Help With Your Goals?

Many of us have been dieting, or at least trying to, for years. The ultimate consensus to lose weight has been to burn more calories than you eat. Although this may make sense, it takes much more input than that. Consuming 500 calories of chocolate cake does not treat the body the same as 500 calories of broccoli. Due to the different reactions of the macronutrients—carbs, protein, and fat, calories are not all created equal. It may seem time-consuming to not only count your calories, but also every single gram of the macros, but it will end up being extremely useful if you are looking to lose weight or improve your fitness.

Athletes especially are one group who will benefit the most from counting their macronutrients, as the amount of protein and carbs significantly impacts their performance and recovery. Endurance athletes are at the greatest risk of injury and burnout if they do not consume enough carbs and protein at specific times surrounding their workouts. Proteins are known to be the building blocks of muscle, so it is obvious why those who exercise should consume a sufficient amount. High protein diets have been studied and seem to be the way to go for weight loss as well. In order to understand what ratio of macronutrients you should be eating you need to take a look at your goals.

Weight Loss

As mentioned, weight loss comes from eating less than you burn. Of course, a mixture of cutting calories and exercising more is the ideal plan, but most people have the hardest time with the diet part. When trying to lower calorie intake enough to make a difference, many dieters become irritable, develop uncontrollable cravings, and end up with barely any energy to get them through a workout. These are reasons why many people cannot stick to a strict diet.

When incorporating macro tracking into a weight loss diet, you can be sure your body is getting all of the nutrients it needs. Keeping protein high means you will stay full for a longer period of time. Enough carbs should keep your energy levels up. Some dieters get used to trying to cut out carbs completely and end up getting scared to add them back into their routines. Keeping tabs on macros shows how a higher carb diet than what you are used to, say 40-50% carbs, will not contribute to weight gain. This is because you will be more aware of what you are putting into your body. Remember, a 1200 calorie-a-day diet of just bacon and eggs will not let you reach your goals like 1200 calories of lean meats, low-glycemic carbs, and healthy fats will.

Gaining Muscle

When trying to get stronger and leaner, putting the time in the weight room is generally the way to go. In reality, if you do not eat a proper diet for this specific goal than gaining muscle will either be almost impossible or take a very long time. Macronutrient ratios will be different if your goal is to gain muscle rather than to lose weight. Protein intake must be higher as this macronutrient is the building block of muscle. But keeping carbs high is also important, as your body will require sufficient energy levels for weightlifting.

Now, gaining muscle and losing fat at the same time (which is most people’s dream!) can be tricky. Thankfully with a macronutrient tracking diet, you can achieve this goal. The key here is to be in a calorie deficit but not too drastic, in order to keep up with muscle building. A deficit of 10% is a good place to start but must be adjusted along the way. It is especially important to look at your protein ratios to make sure the building of muscle outweighs protein breakdown. Being in a calorie deficit with not enough protein will lead to dropping pounds but losing muscle.

Improving Fitness Performance

Runners, particularly those who race, are vulnerable to becoming “skinny fat”. This means they easily lose weight but all of the running basically eats away at their muscle. This means their macronutrients are out of order. Runners must make sure to be consuming enough carbs, around 60% of total calories, to fuel their bodies for endurance training. Keeping protein at a higher ratio is useful to maintain as much of their muscle as possible. The stronger the body, the faster the paces! Fats also have to be accounted for as they help regulate hormones and keep us feeling full throughout the day. A good ratio of macros for a marathon runner is 60% carbs, 25% protein, and 15% fats.

Although this sounds like extra work besides counting calories, it easily becomes habitual. When you realize how well your body responds by keeping within these ratios, you will want to stick with it. Of course, consuming quality foods as the majority of your diet is most beneficial, but macronutrient dieting allows you more freedom and flexibility. As long as you stick to your carb/protein/fat ratios you can feel free to enjoy foods that you love more often and will not feel guilty when cheating a bit. This type of macro diet is popularly known as the “IIFYM” (If it fits your macros) diet. To make things easier there are plenty of applications for macro tracking, such as Macrostax, that allow you to just plug in the meals you eat and it will show you whether those meals fall within your ratios. Once you see quicker results from macro dieting, you won’t go back to your old ways!
