Carb-loading is a strategy commonly used by endurance athletes, such as marathon runners, in the days leading up to a long run or race. This can work well for really fit athletes who have an intense workout regimen or a race on the horizon, but even then it has the potential to backfire if done incorrectly, or if you ordinarily follow a low-carb diet. There are some compelling reasons for professional athletes to rethink carb-loading, in part because high-fat, low-carb diets provide more long-lasting fuel and have an overall better impact on metabolism. Meanwhile, carb loading is totally inappropriate for the vast majority of non-athletes who exercise casually, as this type of regimen could lead to weight gain, digestive issues, and even chronic disease.
There are a couple of serious issues with the idea of carb loading the night before, or in the days leading up to, a marathon or other intense sporting event. Carb loading helps to increase your glycogen stores so that you'll have more energy and be able to run farther before running out of fuel. And if you need to refuel your body in the midst of the event anyway, then your previous carb loading was, mostly, all for naught. Not only is it largely unnecessary, but it can backfire too, causing you to put on extra pounds of water weight (as your body stores water with carbs).
If you've been following a low-carb, Paleo-style diet, or a high-fat, moderate-protein, low-carb diet like the one described in my nutrition plan, your body is probably already fat adapted.
Our ancestors were adapted to using fat as their primary fuel, but nearly all of us are now adapted to using sugar or glucose as our number one fuel source instead. Also if you are overweight, have high blood pressure, diabetes, or are taking a statin drug you most likely are not adapted to burn fat as your primary fuel. Being able to rely more on fat for energy during exertion spares your glycogen for when you really need it. As explained by former Ironman triathlete Mark Sisson, if you can handle exercising without having to carb-load, you're probably fat-adapted.
Replacing non-vegetable carbs with healthy fats, and fasting intermittently, are among the most effective ways to encourage your body to change from burning carbs to burning fat.
So for those of you already following a Paleo diet or similar, you're likely quite efficient at burning fat for fuel and will require very little carb replacement even during intense exercise.
There is some evidence that switching to a higher-carb diet just before a race (after you've been on a low-carb diet) can help to "top off your tanks" to boost your performance… but this is highly individual.
If you carb load prior to exercise, you will actually be inhibiting fat burning and many of the metabolic benefits of exercise, even if it enhances your performance temporarily. Exercising while in a fasted state is actually ideal (see below), but if you feel weak or nauseous while exercising on an empty stomach a high-quality whey protein shake can be an ideal pre-workout snack. This in turn promotes muscle protein synthesis, boosts thyroid, and also protects against declining testosterone levels after exercise. When you exercise while intermittent fasting, it essentially forces your body to shed fat, as your body's fat burning processes are controlled by your sympathetic nervous system (SNS), and your SNS is activated by exercise and lack of food. Instead, eating lots of carbs activates your parasympathetic nervous system, (which promotes energy storage—the complete opposite of what you're aiming for). Exercise and fasting together also yields acute oxidative stress, which actually benefits your muscle triggers genes and growth factors, including brain-derived neurotropic factor (BDNF) and muscle regulatory factors (MRFs), which signal brain stem cells and muscle satellite cells to convert into new neurons and new muscle cells, respectively. This strategy would probably not be appropriate for long endurance exercise, but for the vast majority of casual exercisers, it can be quite beneficial.
For many people, fasting prior to exercise will give you the best of both worlds, helping you to build muscle and burn fat. If you are already fat adapted and a competitive athlete, it is probably not the best idea to regularly train fasted, as it will impair the intensity of the workout and reduce some of the benefits you are seeking to gain.
Hence, if you are doing heavy lifting to failure, you may want to avoid training while fasting.
Endurance athletes who are preparing for competitions may achieve better results if they cut their carbohydrate consumption right down, and replace the carbs with unsaturated fatty acids. You'd expect that endurance athletes would be better off following a diet that provides most kcals in the form of fat – which would encourage their body to learn how to oxidise fats.
After each diet period the researchers got the subjects to cycle for 90 minutes at moderate intensity, and at the end of that time to cycle to the point of exhaustion while the level of exertion was increased every minute.


The researchers monitored the concentration of the enzymes LDH and CK in the athletes' blood. On the other hand the subjects' maximum workload had decreased – at least, after the low-carb diet the athletes generated fewer Watts.
Reason #1 : Sports drinks like Gatorade are useful when they aid the liver in increasing blood glucose supplied to the muscle.
Reason #3 : Most sports drinks are made to look pretty on the shelf, taste really good, and sell really well. So what if you are exercising intensely long enough to drain your muscles of glycogen, and sweating enough in these high-heat conditions to dangerously lower electrolytes? So now you realize that for most, sports drinks are unnecessary. But if you fit the category of hard-charging, long-enduring athlete, congrats!
This is especially true in the high heat of Texas summers that drains electrolytes and water even quicker. This natural version of Gatorade omits the artificial flavors and colors found in standard Gatorade drinks. The idea behind carb-loading is to saturate yourself with carbs so your muscles will have plenty of glycogen to use as fuel while you exercise. Carbs are stored in your muscles and liver in the form of glycogen, which your body uses as fuel. However, if you're burning carbs as your primary source of fuel, you'll still need to refuel during a marathon.
The extra weight from carb loading could easily cancel out any performance benefits, according to Tucker. One way to tell if you're fat adapted or not is to take note of how you feel when you skip a meal.
For many, this strategy may backfire, as the sudden carb consumption may lead to headaches, nausea, bloating, and other symptoms as well. And it's this fat-adapted state that results in improved energy utilization and other benefits, like stem cell regeneration and tissue repair, along with decreased body fat, reduce inflammation, and increased insulin sensitivity.
For this reason, fitness expert Ori Hofmekler recommends flooding your body with stress-activated food nutrients (SAF nutrients) prior to a workout. Some of these nutrients have shown to mimic the anti-obesity, anti-diabetic, and anti-aging effects of exercise and fasting on the body. In practical terms, consuming 20 grams of whey protein before exercise and another serving afterward may yield the double benefit of increasing both fat burning and muscle build-up at the same time. The combination of fasting and exercising maximizes the impact of cellular factors and catalysts (cyclic AMP and AMP Kinases), which force the breakdown of fat and glycogen for energy. One of the easiest ways to do this for most people is simply to exercise before eating breakfast, as you've been fasting since your dinner the night before. What works best for you will depend on the type of activity, your level of fitness, your diet, and your personal goals. In these cases it is likely helpful to consume some healthy slow-releasing starchy carbs the night before working out so your glycogen stores won't be depleted in the morning.
Polish sports scientists drew this conclusion after performing a study in which 8 experienced male mountain bikers followed a low-carb ketogenic diet for four weeks. While performing endurance sports the body burns mainly fat, but many endurance athletes eat huge amounts of carbohydrates (and often the kind that would give anyone with a bit of nutritional knowledge the heebie jeebies).
The researchers gave their subjects a standard diet for four weeks, and then put them on a ketogenic diet for another four weeks. After four weeks on the low-carb diet the mountain bikers had significantly more 'good cholesterol' HDL in their blood. From this the Poles concluded that a ketogenic diet is probably ideal preparation for competition, but that just before and during races endurance athletes are probably better off eating carbohydrates. Your muscles rely on glucose from the liver, through the blood, after they run out of stored glycogen. Enter artificial colors and flavors, food dyes, and sweeteners like aspartame and splenda (sucralose) – often combined with acelsulfame K and others.


Is there any way to maintain peak exercise performance while staying hydrated, and avoid harmful synthetic ingredients? You can and should enjoy the benefits of a beverage filled with water, electrolytes, carbs, and even a bit of protein during your exercise. Furthermore, in some studies drinks with a small amount of protein have helped athletes out-perform those using carb-only type solutions.
With this combo, you get all the benefits of Gatorade plus a substantial increase in potassium (which pulls water into the muscles and aids in reducing cramps).
If you can skip meals without getting ravenous and cranky (or craving carbs), you're likely fat-adapted. You can play with the dose, as that is an average (depending on your weight and stature, you may need half that amount or up to 50%-75% more). On the other hand, eating a full meal, particularly carbohydrates, before your workout will inhibit your sympathetic nervous system and reduce the fat burning effect of your exercise. If your goal is to be an elite athlete who runs the fastest marathon, your nutrition requirements will obviously be very different from someone who is trying to build muscle or lose weight. It's not wise to start a marathon on "empty," for instance, as your body will require massive amounts of energy (but even then, if you're fat adapted this doesn't mean you need to load up on bread, pasta, and other unhealthy carbs).
When you are fasting for 14-18 hours you typically deplete most of your glycogen stores, which makes it difficult to lift your maximum weight to failure.
Then, have whey protein as a pre-exercise meal to grant sufficient supply of branched-chain amino acids for optimum muscle fueling during your workout. From their measurements the Poles could see that the low-carb diet reduced muscle damage incurred during exertion. If you are trying to burn fat stores and extra calories, why drink more calories at the same time?
These have no place in the human body anyway, and certainly provide zero performance benefit.
This particular one uses the herb stevia to help sweeten the flavor, instead of any artificial flavors.
It’s both better and cheaper than Gatorade or Powerade, and void of artificial colors, flavors, and dyes. Not only that it can prevent setbacks with the fat burning and healing impact of exercise, it may actually enhance that impact. However, your muscles store over 2 hours worth of glucose in the form of glycogen, more ready to use than anything in your blood. In fact, take in aspartame consistently and risk building up formaldehyde (yes, embalming fluid) in your tissues. Plus, you can add your own teaspoon of liquid branched-chain amino acids – make sure they are either naturally or non-sweetened. The only people who deplete these stores are those exercising intensely for more than 2 hours. This wood alcohol, or better known as paint thinner, is eventually converted to formaldehyde, which can accumulate in tissue). By the way, the story gets worse when aspartame is exposed to high heat (when many people use the stuff!).
Take your multivitamin twice a day, every day (the good ones will require multiple pills), and get your 5 handfuls of fruits and veggies.
And since you are eating every 3 hours, you’ll have a nice recovery meal inevitably planned post-workout.
