Nutrition: It's about damn time




Have you ever felt dead-legged or worn out during a workout? Do you lift and lift and lift yet can’t seem to put on an ounce of muscle? Are you frequently getting sick or injured? Maybe you feel great and want to perform at an even higher level than you are right now, but you believe something is missing. What you eat, how much you eat, and when you eat can affect your energy, your training, your immune function, and even your risk of injury. What is nutrient timing? Nutrient timing is a strategic approach to how much, what, and when you eat before, during and after training and competition to maximize training effects, reduce risk of injury, maintain healthy immune function, and help with recovery. Nutrient timing is a system of eating meals and snacks in relation to planned exercise. It’s a system of working the composition of your food selection, the portions of your food selection, and the timing of intake of your food so that it does the absolute most it possibly can to help your performance.


Nutrient timing takes advantage of how food influences different chemical reactions inside your body. Various strategies may be used depending on whether you are cycling, lifting weights, running a marathon or a 100-meter dash; or going to football, baseball, lacrosse, or soccer practices, games, or even tournaments. Nutrient timing helps you understand the principles to fuel your body well—and we give you plenty of examples and tips on planning for real-life athletics.


Essentially, the four most important aspects of sports performance are training, skill development, nutrition, and rest. One cannot make up for another. YOU CANNOT OUT WORK A BAD DIET.


Food can’t take the place of appropriate rest. An athlete would never show up for practice without the appropriate gear (soccer cleats, baseball glove, hockey puck, lacrosse stick, and so on), so why would an athlete show up to practice or a game without the proper fuel? Athletes who realize that food is an integral part of training can benefit tremendously. Timing your food intake properly can provide sufficient energy, help you recover for your next practice or event, keep you strong and healthy, reduce muscle breakdown, aid in muscle building, and even promote hypertrophy (gaining size, not just strength), as well as reduce the risk of injury. We also realize that for any nutrition plan to work, it has to be realistic and fit into your lifestyle. Athletes often have challenging schedules, and taking time to eat frequently takes a back seat to all of the other responsibilities in athletes’ lives. We know that trying to balance training along with work, school, family, social commitments, and other interests or activities can be difficult. Meals can be missed or skipped, or eating gets delayed. Did you know that if you skip dinner, it can severely impact your training the following day? What you ate yesterday affects the energy you will have at the end of today’s workout!


Since it takes 24-48 hours to stock and restock the energy your muscles need to get the work done, there is a carry-over from one day to the next in terms of energy level. So many athletes tell us that they never thought of that! Are you aware that when you feel shaky during a run it’s a sign of inadequate fueling to your central nervous system – which only runs on carbohydrate? When there are long gaps without food, appetite and eating can become disconnected. Many athletes ask us why they can’t stop eating at night—from recreational to college athletes and even some pros. It often happens when you’re under-fueled during the day, and when the opportunity to eat presents itself, it’s like a dam broke! And it’s not all nutritious food that’s consumed.


Calories are potential energy to be used by muscles, tissues, and organs to fuel the task at hand. Much of the food we eat is not burned immediately for energy the minute it’s consumed. Rather, our bodies digest, absorb, and prepare it so that it can give us the kind of energy we need, when we need it. We transform this potential energy differently for different tasks. How we convert potential energy into usable energy is based on what needs to get done and how well prepared our bodies are; how we fuel endurance work is different from how we fuel a short, intense run.


If you’re tired because you haven’t slept enough, for instance, eating isn’t going to give you energy. However, if your lack of energy is because you’ve eaten too little, your foods don’t have “staying power,” you go for too long without eating, or you don’t time your meals and snacks ideally around practice or conditioning, then being strategic with food intake can help you feel more energetic. What, how much, and when you eat will affect your energy. Nutrient timing combined with appropriate training maximizes the availability of the energy source you need to get the job done, helps ensure that you have fuel ready and available when you need it, and improves your energy-burning systems. You may believe that just eating when you are hungry is enough, and in some cases this may be true. But, many times, demands on time interfere with fueling or refueling, and it takes conscious thought and action to make it happen. Additionally, appetites are thrown off by training, so you may not be hungry right after practice, but by not eating, you are starving while sitting at your desk in class or at work. Many athletes just don’t know when and what to eat to optimize their energy stores.


During the minutes and hours after exercise, your muscles are recovering from the work you just performed. The energy used and damage that occurred during exercise needs to be restored and repaired so that you are able to function at a high level at your next workout. Some of this damage is actually necessary to signal repair and growth, and it is this repair and growth that results in gained strength. Providing the right nutrients, in the right amounts, at the right time can minimize this damage and restore energy in time for the next training session or competition. The enzymes and hormones that help move nutrients into your muscles are most active right after exercise. Providing the appropriate nutrients at this crucial time helps to start the repair process. However, this is only one of the crucial times to help repair. Because of limitations in digestion, some nutrients, such as protein, need to be taken over time rather than only right after training, so ingesting protein throughout the day at regular intervals is a much better strategy for the body than ingesting a lot at one meal. Additionally, stored carbohydrate energy (glycogen and glucose) and lost fluids may take time to replace. By replacing fuel that was burned and providing nutrients to muscle tissue, you can ensure that your body will repair muscle fibers and restore your energy reserves.


Muscle breakdown and muscle building nutrient timing capitalizes on minimizing muscle tissue breakdown that occurs during and after training and maximizing the muscle repair and building process that occurs afterwards. Carbohydrates stored in muscles fuels weight training and protects against excessive tissue breakdown and soreness. Consuming protein and carbohydrate after training has been shown to help hypertrophy (adding size to your muscle). The proper amount and mix of nutrients taken at specific times enables your body to utilize them most efficiently—that’s one of the Nutrient Timing Principles. Nutrient timing can have a significant impact on immunity for athletes. It has been shown that exercising when muscles are depleted or low in carbohydrate stores (glycogen) reduces the blood levels of many immune cells, allowing for invasion of viruses. In addition, exercising in a carbohydrate-depleted state causes a rise in stress hormones and other inflammatory molecules. When carbohydrate is taken, particularly during longer-duration endurance training (two to three hours), the drop in immune cells is lessened, and the stress hormone and inflammatory markers are suppressed. Carbohydrate intake frees amino acids, allowing their use by the immune system. Carbohydrate intake during endurance training helps preserve immune function and prevent inflammation. Certain vitamins and minerals also play a role in immunity: iron, zinc, and vitamins A, C, E, B6, and B12. However, excess intake of iron, zinc, and vitamins A, C, and E can have the opposite effect and in some cases impair the body’s adaptation to training. An eating plan incorporating all of these nutrients in reasonable quantities, such as amounts found in food, can help athletes maintain immunity. The quality of the foods selected is very important and needs to be just as much of a priority as the focus on carbohydrate or protein, for example.


Did you know that dehydration and low blood sugar can actually increase your risk of injury? Avoiding injury due to poor nutrition is absolutely within your control. Inadequate hydration results in fatigue and lack of concentration. Low blood sugar results in inadequate fueling to the brain and central nervous system. This leads to poor reaction time and slowness. Poor co-ordination as a result can lead to missteps, inattention, and injury. Additionally, chronic energy drain (taking in fewer calories and nutrients than needed) will increase your risk of overuse injuries over time. Stress fractures are one example; poor tissue integrity can happen when athletes think solely about calories taken in but not the quality of the calories consumed. This is what is behind the phrase “overfed but undernourished.” Eating lots of nutrient-poor foods will not provide your body with the building blocks for healthy tissues and overall repair. Inadequate protein will also hinder the rebuilding of damaged muscles during training. If muscles are not completely repaired, they will not be as strong as they could be and will not function optimally. The damaged muscle fibers can lead to soft tissue injuries. Both protein and carbohydrate along with certain nutrients are needed to help with this repair. For instance, gummy bears may provide carbohydrate, but they don’t contain any vitamin E, which is helpful in repairing soft-tissue damage that occurs daily during training.


TIMING TIP: Nutrient timing transforms eating into a strategic component of your training, conditioning, and sports performance. By co-ordinating food intake at the right time with regard to your training, you will be able to take better advantage of the changes in body chemistry that occur with eating and exercise to help with muscle building; to maximize energy storage, which can help generate power and promote endurance; and to facilitate muscle recovery and keep you healthy throughout your training.


TIMING TIP: The right mix of nutrients taken just after exercise helps muscles recover, but nutrients must be consumed within the context of an overall well-designed training diet to be most effective.


TIMING TIP: Eating a small amount of protein, such as poultry, lean meats, fish, eggs, milk, or yogurt, with each meal and snack will help utilize it effectively for muscle building and repair.
