Running While Breastfeeding

Many women believe breastfeeding their child will help them lose the weight they gained while pregnant. While it’s true that breastfeeding burns about 500 calories a day. If you’re not running a deficit you’re not going to lose weight. But how much of a deficit is okay when your breastfeeding?

This is an important question for any endurance running mother who is breastfeeding her child, even when not trying to lose weight. Having enough milk to feed your child is obviously very important if you want to continue breastfeeding. The best way to maintain your milk supply is to drink lots of water and eat enough calories.

Many ultrarunners survive on calorie deficit pretty much everyday. Even marathon runners are going to have days where they don’t replace all of the calories they’ve burned. If you’re trying to lose weight, you’re going to have to fiddle with your calorie intake, but start with a 200 calorie deficit. Wait a couple of weeks before creating a bigger deficit. You shouldn’t be doing any dieting until your milk supply is well established at about eight weeks post partum. You shouldn’t be losing more than a pound a week.

Runners who are not trying to lose weight will need to monitor their calorie intake and milk supply.

The available research shows that exercise does not impact the composition of your milk. Breast milk contains protein, carbohydrates, and fats to help your baby grow. The other important thing your milk gives your baby are the antibodies you already have in your system.  This is a major reason breastfeeding is recommended. Your baby can’t get those antibodies from formula.

Spend some money on a good sports bra. You’re going to need some solid support. And when your baby is under a year, you probably need a bra you can nurse in too. The Brooks Juno has been perfect for me.

Newborns eat every two hours or more frequently. Feeding on demand is the best way to make sure you have enough milk and your baby is getting what he/she needs. Infants feed every 3 hours. This means it’s going to impact your running. Once your baby has a schedule, you should be able to get away for shorter runs. Long runs over two or three hours will require some planning and help. You’ll either have to have someone bottle feed your baby expressed milk or bring the baby to you to feed her. If you bottle feed, the issue you’ll run into is full breasts. You’ll have to stop to pump milk. There is a new breast pump called the Willow. It fits into your bra and doesn’t have any wires or tubes. Find it here.

Running ultras and breast feeding are definitely compatible.  Here are some tips to make the partnership work out:

  1. Feed baby or pump before you go out for a run
  2. Make sure you are consuming enough water and calories to maintain your milk supply.
  3. Find a way to pump on the run or feed baby during long runs.
  4. Get a really supportive sports bra.
  5. Be flexible with your running schedule to meet your baby’s needs especially before some predictability is established.
  6. Consider splitting long runs up.
  7. Take baby with you on runs and stop to feed if needed.
  8. Pay attention to caffeine in your sports gels, chews, and hydration.
  9. Throw a hand pump in drop bags where you can’t feed your baby. You’ll just have to dump it, but it will make you more comfortable. You don’t have to empty your breast just skim some off the top.
  10. Practice the plan during training, before you register for a race.

Happy running!

 

 

 

Training not Where You Wanted it to Be?

Life can get in the way of the best laid plans. Even when running is LIFE, the other pieces can interfere and put us a week out from race day with inadequate training and a mindset lacking in enthusiasm for the event ahead of us.

What do you do when your training just hasn’t been what you wanted it to be? Maybe it has been a lot less than you wanted it to be, to the point where you’re questioning your ability to finish the race? You have three options to choose from.

First, you can DNS (did not start) and cut your losses with that (most races won’t let you transfer your registration to another runner or carry it over to the next year). Second, you can go out hard pretending that your training was amazing and nothing can stop you. Third, you can show up to the start and see what the day brings with only an expectation to enjoy yourself.

The second option is likely to get you injured, which will only compound any frustration you feel about the situation. The first, I can understand if you’re coming back from an injury, which has killed your training and you really don’t want to risk causing more injury or compromising the healing process.

The third is the option I encourage most runners to take. You paid for the race after all and I think you will surprise yourself if you hold to a few suggestions and trust in your running foundation.

It’s important that you stay positive about the event and situation as much as possible-Hey at least you’re able to be out there. Make sure you are encouraging other runners as you come in contact with them along the course. Not only will your encouraging words impact them, they will impact you because, you hear them as well.

Summon your inner confidence. You’re a strong runner who has done hard things before. You finished races before. You know where to slow down and where to pick up the pace. You know how to fuel and hydrate. You know how to utilize your crew and pacers to help you reach the finish line. You’ve dealt with the “pain and suffering” of running before and can do it again.

Don’t discount consistency. If you’ve been able to maintain consistency in your training schedule but not the miles remember that consistency goes a long long way when it comes to running. Yeah, sure you wish you could have gotten in more long runs and more time on the trails, but at least you ran every day you had scheduled to be a run day even if it was only for an hour. Consistency keeps your muscles and tendons strong. It also keeps your mental game strong.

Trust your foundation. If you’ve been running for years and this is just one of many races you’ve done trust your body. You have the running foundation to push through a race even on less than the best training.

Get out to the starting line and assess your body’s condition as you go. You don’t want to get injured, but don’t miss a chance to play on the trails and show yourself you can do things even when they don’t turn out just the way you had planned.

Reduce Race Day Nerves

You’ve been training for months and months and race day is fast approaching. Staring down an ultra can cause a little anxiety, even among experienced runners. There are a few things you can do to reduce some of that race day anxiety you may experience.

Know the course and the rules of that particular race.

Knowing the course is important, from the time you start planning your training schedule and runs. Shaping your training to meet the demands of the course you’ll be running as closely as possible (or harder) is going to make you much more confident and comfortable when you head out from the starting line.

Knowing the course also makes it easier to plan and pace. If you know where the climbs and descents are, you can give a good prediction as to when you’ll be coming into the various aid stations. This is important because your crew, if you have one, will need to know what time they need to be at each aid station. In some races the space is limited and crews can only enter an aid station within a certain amount of time of their runners expected arrival.

Being able to calculate your pace lets you plan for what to put in drop bags at the aid stations. You’ll have a good idea of which aid stations you’ll go through during the night and be able to pack headlamps and warmer clothing, as needed. Getting all your drop bags ready 4-5 days in advance of race day will help you stay calm and not feel rushed the day or two before.  

You’ll need to know cut off times, when you can have a pacer, and where your crew is allowed to be. In many ultras, there are some aid stations where crews just can’t get to or aren’t allowed do to space or other reasons. You’ll want to make sure you have a drop bag with all the stuff you might need there especially if it’s going to be another 10-15 miles until you see your crew. In most 50 mile races you’re not allowed to have a pacer until at least 30 miles in and for most 100s its going to be around mile 40-50 (usually when the majority of runners are going to be heading into the nighttime hours).

Something you can do throughout your training to reduce your race day anxiety is to not duck out of training runs that are difficult due to the weather or because you stayed up too late the night before. Even if your stomach is a little edgy, I would encourage you to go out and get miles in. The weather on race day could be anything and if you’ve run in similar conditions, you won’t worry about it so much on race day. Weather can also change very quickly during mountain races. When you’re out in the mountains for 24-36 hours you can see sun, rain, and snow. So make sure you know what is within the range of normal for the area you’re race is in.

Have a fuel and hydration plan. If the menu is not included in the race details, you may want to contact the race director or just plan to bring your own food and electrolytes. It’s fine to grab some potato chips at an aid station if they look really good, even if you don’t generally train with them. Do not try anything that’s “complicated” or has a lot of ingredients unless you’ve tried it before. During your training, experiment with different foods and find what works for you. You’ll need a few options because eating the same thing for 100 miles is tough. Same goes with electrolytes and water. Pay attention during your training runs and keep logs of what you’re consuming, how much, and the temperature outside.

Reducing your nerves on race day really begins during training because that’s when you should be building confidence in your ability to tackle the challenges of the course (course specific training), and developing a good fuel and hydration plan (keep a training log).

Taper Adaptations

Tapering for a race is really difficult for many runners. I know that there are some elite athletes who don’t really taper at all, although, they may take the two days before a race off. An important, possibly critical, difference between elite runners (many not all) and us not so elite runners is we all work typically full-time jobs. This means we don’t have the same opportunity to recover between our runs during training and thus we reach race day more depleted making tapering more important for the average runner.

I’ve tried both three week tapers and two week tapers. I didn’t find any difference between the two. Again, that’s me. Other people may be different. Tapering is– as many aspects of running are– very runner dependent.

The professional research based recommendation is three to four weeks. This is because a taper  is giving your body the time and rest needed to take all the training you’ve been doing and lock it into place in your various bodily systems.

For ultrarunners, your aerobic system has pretty much reached maximum conditioning. Other system haven’t. There are actual changes down to the protein synthesis level. Some of the adaptations that your  body makes during your taper are:

  1. Training causes minor tears to muscles. The muscle need a chance to rebound and repair.
  2. Immune system needs time to get rid of any inflammation and repair cells.
  3. Hormone profile rebounds which takes some time especially cortisol and testosterone. Both of these become depleted during your training.
  4. Red blood cells become consistently damaged when you’re running high miles, so your having to manage that while training. The taper allows those to be repaired and to increase. This is important for oxygen transportation to muscles.
  5. Metabolic wise, rest allows you to store more  glycogen in your muscles and liver.
  6. Running 100 miles is a mental as well as physical challenge. We also tend to be a bit sleep deprived which has both physical an mental components impacting our performance. It improves your vigor and mood.
  7. Many ultrarunners have some level of dehydration pretty much all the time. The taper gives you time to balance your hydration.

In addition to sleep and reducing your running, nutrition is a major part of recovery. Eat healthy whole foods, which will give you what you  need and reduce the chance of gaining weight close to the race once your body is using less calories to rebuild.

Regardless of whether you run by time or miles, you should reduce your running by 20% each week beginning three weeks from race. You on’t need to reduce the intensity, but you shouldn’t increase it. You can maintain the number of runs per week. It’s very important that you keep in mind you are going to feel better as your body rests and recovers (the point of the taper), but you shouldn’t increase your efforts. You’ll need to use pace rather than perceived effort during your runs. You’re not going to lose any fitness by giving yourself the three weeks to rest and repair.

Here is an easy way to remember the “rules” of tapering:

Trust in your training

Adjust your Calorie Intake

Perfect your race day strategy

Embrace the “free” time

Rest and recover

Nature vs. Nurture

We’ve all heard that the Kenyans are built for running-it’s in their genes. Statements like that raise more questions for me, such as: do genes(nature) limit my ability to improve my running? do my genes determine what type of training(nurture) or races I should do? How much of my improvement is from my pure stubbornness to succeed (is that genetic too?)?

I think it’s obvious that both genes and training play a role in our progress and ability in our sports. And I’m not sure if knowing which one is dominant is helpful because if it’s genes, the brain of many runners could get in the way of them making improvements through training hard due to a belief that they are limited.

There are more than 100 genes that have an impact on physical capacity. The belief that our genes determine our running performance seems reasonable, after all, our genes determine our body size and shape. Both of these influence our running performance. Those with smaller bone structures are going to be lighter on their feet. They are less likely to have non-propulsive muscle mass weighing them down.

Two measures scientists use for unraveling the nature vs. nurture questions are VO2 max and Lactate threshold. What they’ve discovered is that the degree to which VO2 max increases in response to exercise has a 47% genetic component. That leaves 53% friends-more than half. The degree to which Lactate threshold increases in response to exercise is a 55-80% genetic component. That’s a pretty big spread if you ask me.

How important is VO2 Max for ultrarunning? VO2 max is the highest rate at which your body can transport oxygen to your muscles, through blood, to provide your muscles with the energy they need. Most people can only sustain this level of effort for 8 minutes. Not helpful in an ultra that lasts up to 36 hours. Your VO2 max becomes less important as the distance of your run increases. This is not to say doing VO2 max training isn’t worth while. See my post on that here.

What about Lactate Threshold (LT)? LT is the point at which the level of lactate accumulating in your blood is higher than what your body can get rid of. During lower intensity exercise (ultrarunning by nature), lactate levels remain at or near resting levels- a steady state. Training your LT is still important. See my post referenced at the end of the last paragraph.

Other factors that determine running performance are diet, attitude toward running, daily activity pattern, amount of sleep, injuries, running efficiency, determination, and much more. What the science has concluded so far is there are just too many genes that impact sport performance to be able to predict who will be a good athlete and who will not.

So what can our genes tell us? no more than our personal experience which is the better route to go. Yes, there are companies out there who will test your DNA and tell you if you have a low, medium, or high aerobic potential, but I ask again does that really help you to know? I think this is a situation where ignorance is bliss. If we believe we have an insurmountable genetic limit, it will become a self-fulfilling prophecy.

I look out there at my fellow ultrarunners and I see the “impossible” accomplished at every race. Grit is a better predictor of our ability to succeed than any genetic test.

 

 

First Ultra?

I love running and I want everyone else to love running, so I try to make this crazy ultrarunning thing easier for others to wrap their minds around and jump in. Here are my eight quick tips for runners who want to make the leap to ultrarunning:

  1. Physical Training.

Training must be a priority and it must be consistent. You don’t have to run a hundred miles a week to be an ultrarunner. Many ultrarunners run 60 miles a week and complete 100-milers. Your training does need to be race specific. If the race has mountains, you train mountains. If the race is flat, you train flat. If it’s going to be hot, run in the heat. If you’ll run through the night, train in the dark.  Weekly long runs, up to 20-30 miles, are a must. Back-to-Back runs should be done at least a few times throughout your training. Speed work is good to include, but not necessary. Be careful, speed increases your risk of injury.

  1. Mental training.

In ultrarunning, training your mind is as important as training your body. There will be dark times during the race where you question your ability to go on. Positive self-talk, mantras, and remembering how you’ve overcome other difficult times can get you through them. My favorite is, no matter how dark it gets, the sun always rises.

  1. Rest.

An injury is the last thing you want to have as you near your goal race. Taking a rest week every fourth week by cutting your miles back by 20%, will decrease your risk of injury and help build your endurance and strength. Listen to your body and take a rest day when needed. It’s better to take a break early in training than push through and have it get worse and force you to rest late in training.

  1. Strength training.

It’s more important to add strength training than to cross train or to stretch. Core and hip strength are critical to maintaining your running form and preventing injuries. Two to three days a week is enough. If you have time add in squats and deadlifts with low repetitions(4-5) and maximum weight 4-5 days a week.

  1. Nutrition plan.

Plan what you’re going to eat during your race. If you’re going to take stuff from the aid station, know what’s there. Train with what you plan to use in the race (this goes for gear/clothes too). Relying on gels and chews is not enough for most ultrarunners. Train with solid foods that are easy to digest, high in carbs, low in protein and low in fiber. Use caffeine strategically. Stop using caffeine a month before the race, so you can use it to stay alert during the night portions of the race.

Know your hydration needs. Drinking to thirst isn’t enough during an ultra and electrolytes are a must.There are a lot of sports drinks out there, find one that works for you or use salt capsules. Pack enough for the whole race in your drop bags and with your crew.

  1. Body Functioning issues.

Plan for dealing with blisters, vomiting, diarrhea, dehydration, nausea, cramps, aches, and general pain. We all hope we don’t have to deal with these issues, but if you’re caught unprepared they can ruin your race. I keep a blister kit with my crew and a small one in my hydration pack. I also have ginger chews, antacids, Imodium, and Icy Hot. I avoid any pain medication.

  1. Crew/pacers.

Chose happy supportive people who won’t let you back out of your goals, even if you’re crying and limping. Family and spouses are not always the best for this. Finding crew and pacers who have experience with ultrarunning is going to be very helpful to you. If you don’t have anyone with experience, you’re going to need to educate them as best you can. See my page on the Ultra crew.

  1. TAPER wisely.

Trust in your training.

Adjust your calorie intake to match your decreased training.

Perfect your race day strategy.

Embrace the “free” time.

Rest and recover.

Hydrating, It’s Complicated.

Staying hydrated is essential to being able to sustain a good pace on race day. Too much or too little water can cause serious problems for runners. Maintaining optimal hydration is more complicated than we’d all like.

There are many factors that play a role in your hydration during training and races. We all hear the pervasive message of 8 glasses of 8 oz of water a day, but is that right for everyone? It’s not even close. It’s difficult to calculate exactly how much fluid a person needs each day. Some factors that impact your recommended fluid intake are: the type of food you eat, your activity level, your body fat percentage, and your acclimatization to the heat.

Another recommendation we hear a lot is to drink to thirst, but once again the phrase, “it’s complicated,” rears it’s head. When you’re exercising, especially for extended periods of time, your body may not signal you to drink because of imbalances in your system. You need to be looking at other objective measures such as the amount of fluid you are taking in, the temperature, the color of your urine (we’ll talk about this more in a few paragraphs), and any GI issues you’re having.

You’re unlikely to need to hydrate during a 5k or 10k event. For a 1-2 hour run, you’ll need water, but not electrolytes. If you’re running five plus hours, you’re going to need some form of electrolyte replacement strategy. If you’re between the 2-5 hour range, water is necessary and electrolytes would be helpful but are not necessary like they are after 5-6 hours. Electrolytes are helpful in the 2-5 hour range because they help you hold onto the water you’re consuming rather than it just going straight through you.

 

Most ultrarunners use some type of electrolyte supplement during training and in races. There are lots of options as far as different sports drinks, powders, and tablets/capsules. It’s likely that you’ll want a variety of options when you’re racing because things change and some times something that has worked throughout training suddenly stops working. Sports drinks usually do double duty by providing you with both carbohydrate and electrolytes, so make sure you have options for both when the drink doesn’t work so well. Aid stations typical fare will consist of foods with both carbohydrate and with sodium, the main electrolyte you need, so keep a mental note that you’ve taken in some electrolytes there too.

After a run or a race, there’s no need to ingest a sports drink to replenish your electrolytes. Your body will be able to balance it out within the next 24-48 hours. If you have another run within that time frame, however, drinking a Gatorade is probably a good idea.

One way runners often judge their hydration is through urine color. The problem is there are a lot of things that impact your urine color, so it’s not always the most accurate. You can have clear urine because your body doesn’t have enough electrolytes to hold onto the water so it just spits it back out. The best time to judge hydration with urine color is when you first wake up in the morning because it’s had time to accumulate. The first urine in the morning tells you about your hydration the day before. So if you track your hydration and exercise, you’ll get a good idea of what your body needs for different workouts.

 

 

 

Carbohydrate Intake and Uptake

Carbohydrates are the energy source most runners use to fuel their training and their racing. Wait? most runners. That’s right there are some runners out there who use fats, protein, and even nothing. But this blog is about the carbohydrates. Carbohydrates are broken down into glucose, which is what our bodies burn to fuel our muscles, nerves, and brains. Our bodies can store glucose as glycogen in our muscles, but it’s limited. When we run out, we hit the infamous WALL, if we haven’t properly fueled. Our blood also has glucose floating around. Maintaining our blood sugar level is how we prevent hitting, or reduce the impact of, the wall.

Ultrarunners and even some marathon runners struggle with GI issues and are constantly on the look out for ways to optimize their fueling strategy and minimize GI distress. It seems like a never ending cycle, and I’m not here to tell you there’s a way to end it, but there are different things to experiment with and thereby, possibly minimize your discomfort. In our efforts to maintain our blood sugar level and avoid the wall, we may overload on the carbs which causes sloshing, cramps, bloating, and other nasty things in our stomachs.

So the trick to minimizing GI issues, is knowing how much to intake to maximize uptake, but not overload the system. This blog is also for those who don’t suffer from GI issues, since we’re going to look at how much carbohydrate a body can uptake.

Depending on the intensity you’re running at, you’re going to run out of glycogen stores withing about 90 minutes to three hours as an average endurance runner. To maintain your blood sugar levels you need to start taking carbs in right before you begin your race or a long training run. Then, you’ll need to take more at regular intervals to meet that 60-90 grams per hour.

What we know is that regardless of how many grams of carbohydrates you intake, your body can only uptake between 60-90 grams an hour. What determines whether it’s 60 or 90 is the type of carbohydrate your taking in. Your body can process about 60 grams of glucose an hour. So if all you’re getting is glucose, don’t try to put more than 60 grams an hour in.

To get to the 90 grams an hour, you have to combine the 60 grams of glucose with 30 grams of fructose (although sucrose is a combination of fructose and glucose it’s not processed the same so avoid sucrose as a source of fuel). The reason your body can handle the 90 grams of carb processing is because glucose and fructose take different paths to be absorbed by your body.

Sixty grams of glucose produces about 232 calories. Thirty grams of fructose produces about 120 calories. For a grand total of 352 calories replaced during every hour if you play your cards right.

Dextrose and Maltodextrin are made from starches, but are absorbed like glucose. This is nice to know because fructose is very sweet and sometimes sweet things become intolerable during a race. Maltodextrin and Dextrose are not as sweet as glucose and so they can be combined with fructose to get the same benefit of the 90 grams of carbs.

Water intake with the carbs is important. Your digestive system needs water to break things down and get it into your blood stream to be used. Without water, it just sits in your stomach (which is why dehydration causes GI issues). If you put more than the 60-90 grams in an hour, your body is not going to be able to absorb them and they will just sit in your stomach causing problems.

What if you’re feeling depleted, but can’t stomach more food/gels/chews? You can rinse your mouth with a carbohydrate rich drink and spit it out. This will make your brain think that carbs are on the way and give you a little boost for a little bit, but unless your close to the finish line, you still need to figure out your GI issue.

 

How many carbs do I burn when running?

Carbohydrates are one source of fuel our bodies use to provide energy for our daily activities and for our runs. Fat is the other source of fuel our bodies use. Carbohydrates have to be replaced during training and racing, but fats don’t. How much and how quickly we burn through carbohydrates and fats depends on a variety of factors. Understanding how many calories we burn and where it comes from can help us dial in our nutrition plan for race day and for training.

When we run fast and for shorter distances we burn mostly carbohydrates. As our distance increases and our pace decreases we begin to use fat as a fuel source too. We begin to use fat at slower long distance events because we have a lot of energy stored up in fat, even very thin people. Fat takes more oxygen to burn so if you’re running hard, it’s not a good source of energy. Fat also takes longer to burn, so if you’re running fast, it’s not a good source. If you’re running a 5k-half marathon, you’re tapping into your carbohydrate stores and burning very little fat.

This is the core of the belief that endurance athletes can perform well on a low carbohydrate diet. The problem comes when the same athlete tries to push hard and go fast. I raced and trained on a low carbohydrate diet for 18 months and was fine, unless I wanted to push my limits and then…I died. Despite being low carb (under 50 g a day), my body still could not burn fat fast enough to sustain hard effort. So I switched back to a higher carbohydrate diet.

One way to figure out the ratio of carb to fat that you are burning is to use your heart rate. To do this you need to know what your maximum heart rate is (220- your age. This is a guestimate). During your run, check your heart rate. At 70 percent of your max heart rate, about 50 percent of your fuel comes from carbohydrates. At 75-80 percent of your max, it increases to 65% carbohydrate.

So a person who is 150 lbs, running at a 7 mph pace (8.5 min/mile) for one hour burns about 782 calories. If that puts the person at 70% heart rate that’s 391 calories from carbohydrate. At 75-80% heart rate that’s, 508 calories from carbohydrates. The same person running at a 5 mph pace (12min/mile) burns 544. Because they are going slower, the amount of calories coming from carbs is less and the amount coming from fats is more.

The American Council on Exercise has a physical activity calorie counter that is based on your body weight, duration of exercise, and intensity. You can find it here. There are a bunch of different tools there to try out, if you’re curious.

Once you know how many calories per hour you’re burning on average during your runs, you can begin to understand and build a strategy for resupplying your body with those calories. Your body cannot process enough food to be able to make up for the amount of calories lost through carbohydrate burn if you maintain a high intensity. The most you can hope to process per hour is about 352 calories. We’ll get into how to maximize that in the next post.

 

 

Protein Intake

We all hear so much about carbohydrates, but we don’t hear a lot about protein. Many runners think that since they’re not trying to gain muscle mass protein isn’t as important. And that is where they would be wrong.

Protein is essential for people who are trying to build muscle mass, but endurance athletes need just as much and ultrarunners may need more. The recommended amount of protein for the average Joe is 0.8 grams per kilogram of body weight. For endurance athletes the recommendation is 1.5-1.7 grams per kilogram of body weight. For ultrarunners, it jumps to 1.8 to 2.0 grams per kilogram of body weight.

Why we need so much protein? because we push our bodies on a regular basis. And we don’t just push them a little bit. We push them beyond what most people call reasonable. We need the protein to repair those micro tears that occur through our regular training. We need the protein to strengthen our muscles when we’re doing our weight lifting throughout the week. Finally, protein is converted into energy by our bodies, requiring us to take in a little more to make sure we have enough to repair and strengthen.

Our protein intake should be spread out over the day. You’re body can only process and use so much protein at a time so taking more than 25 grams at one time doesn’t do you a whole lot of good. Eating six smaller meals throughout the day rather than three large meals, makes spreading protein out much easier. You don’t have to use protein shakes either. There are many healthy sources of protein to fit any eating lifestyle. Obtaining all of your protein from animal sources has its health consequences. If you’re vegetarian or vegan, you need to make sure you are getting your protein from a variety of sources to ensure you’re getting all nine essential amino acids (there are more amino acids, but your body can produce all but nine of them).

Another myth is that you need to take in so much protein within a specific length of time after your workouts because your body is primed for absorption. This is true when it comes to carbohydrates, but not for protein. There isn’t a do or die time frame for getting it in after a workout. That said, it’s best to get it in as soon as you can so you don’t get behind in your intake for the day. Also, protein can help with the absorption of carbohydrate after a hard workout. This is only the case when your body is carb depleted. Ever heard of the 4:1 carb to protein ration after a hard workout? It comes from this benefit.

Your body’s ability to absorb protein when it is working, like in a training run or a race, is very limited. Most people are fine with about 1% of their fuel intake being protein. Much more beyond that and you could suffer some GI issues because protein is harder for your body to break down, which means it could be sitting in your stomach sloshing around for some time.
