One of the most frequently asked questions trainers and nutrition coaches hear is: “What should I eat before and after working out?”
- Protein = Your Savings Account Protein breaks down into amino acids that your body uses to build healthy new muscle tissue and to transport and store nutrients in your body. Protein also requires more energy than fat or carbs to break down into amino acids (20-30% of total caloric content of that food!) to be used. It’s good to have protein available so that your body can manage the muscle damage you are creating during your workout for faster recovery and better performance.
- Carbs = Your Quick Cash and Checking Account Your body uses the glucose from carbs for quick access energy. Your muscles and liver also have limited stores of glycogen (the storage form of glucose) that can be tapped into for energy for shorter duration/high-intensity exercise like sprints and power movements like kettlebell swings.
- Fats = Your Retirement Account Stored fat in your organs is needed for longer duration exercises (think long-distance running, cycling, etc). Your body needs more energy and time to break down fat stores for energy use than protein and carbohydrates, but they are the best source of energy for longer duration, lower-intensity exercise.
- Hydration / Fluid Balance While one of the most overlooked factors, hydration is key to keeping your energy up during your workouts and for optimal recovery afterwards. Did you know that as little as 1-2% reduction in bodyweight from water loss leads to decreasing performance during activity? Especially if you’re doing a morning workout, remember that you just spent all those sleeping hours without any water intake, so make sure to rehydrate prior to exercise. Consuming electrolytes such as sodium and potassium will also help maintain fluid balance, therefore performance, during exercise and for recovery afterward.
PRE-WORKOUT What you will want to eat and also what your stomach will be happiest with will depend on exercise choice too. Most people don’t do well with a heavy and fat-dense meal right before a bootcamp class full of high-intensity, short interval movements. Something more easily digestible will make you happier. Conversely, for a 10-mile run, your body will likely appreciate more than just a simple banana beforehand — some energy-sustaining fats like nuts or avocado about two hours prior will better help with endurance.
If Working Out in 1-3 Hours Choose a general, well-rounded small meal or filling snack with a good balance of carbs, proteins, and fats, such as oatmeal with berries and nut butter, salad with protein and fats, fruit and nut butter, avocado toast with egg, greek yogurt with fruit or granola, a small nutrient-dense smoothie, or a handful of nuts with fruits and veggies.
If Working Out in Less Than 30 Minutes Choose something lighter and more carb-focused for some readily available glucose in your bloodstream, like some fruit or crackers, and make sure you are hydrated. It is better to have a bit of food prior to exercise, if you can comfortably stomach it.
POST-WORKOUT Your body doesn’t really live paycheck to paycheck. It primarily uses yesterday’s paycheck (aka nutrients) that it stored in the organ piggy bank for today’s living, breathing, and exercise. So part of the refueling process post-workout is crucial to replenishing energy (glycogen) in the bank for the next day.
Your metabolic rate is also raised post-workout, but that doesn’t only mean that you’re burning calories faster — your body’s processing systems are also working at high-speed, and it is very receptive to nutrition and recovery.
That being said, the everyday person (aka non-professional athlete) need not stress about stuffing beef jerky in his or her mouth within 30 minutes of a workout to attain that “anabolic window.” Nutrient timing can be a helpful tool, but it’s more important that you’re consistently eating nutritious food and exercising regularly. Eating a healthy post-workout meal or snack within 1-2 hours is a great goal to replenish glycogen, decrease protein breakdown and increase protein synthesis; in other words, to refuel, preserve lean muscle, reduce soreness and help your body’s ability to build new healthy tissue.
