To Eat or Not to Eat Before Working Out

Whether to eat before hitting the gym is a common question. While some swear by pre-workout meals, others prefer exercising on an empty stomach. It’s a dilemma many of us face, and the answer isn’t always clear-cut. Amidst this confusion, it’s essential to understand the science behind pre-workout nutrition to optimize your performance and results. Let’s break it down into practical, no-nonsense advice.

Let’s bust some myths before we start.

Myth: Fasted Cardio Burns More Fat.

Fact: While fasted cardio may increase fat oxidation during the workout, it doesn’t necessarily result in greater overall fat loss. Total energy expenditure throughout the day matters most for fat loss, not just during the workout.

Myth: Fasted Workouts Boost Metabolism.

Fact: While exercise can temporarily increase metabolic rate, the impact of fasted workouts on long-term metabolism and calorie burn is minimal compared to other factors like muscle mass, activity level, and overall diet.

Myth: Fasted Workouts Preserve Muscle Mass.

Fact: Fasted workouts may actually increase muscle breakdown, especially during intense or prolonged exercise sessions. Consuming protein before a workout can help prevent muscle breakdown and support muscle repair and growth.

Myth: Fasted Workouts Improve Performance.

Fact: Exercising on an empty stomach may impair performance for some individuals due to decreased energy levels, reduced strength and endurance, and impaired cognitive function.

Now that the stage is set let’s begin.

Many athletes and fitness enthusiasts have their own pre-workout rituals and preferences. Some swear by a hearty breakfast before hitting the gym, while others thrive on fasted workouts. The key is to find what fuels your body and enhances your performance.

To each his own. But if you ask me, a simple pre-workout snack can amplify your workout session in a big way. This is backed by research.

• “Studies suggest that eating or drinking carbohydrates before exercise can help you do better during your workout. And the carbohydrates may allow you to work out for a longer time or at a higher intensity. If you don’t eat, you might feel slow-moving or lightheaded when you exercise.” Mayo Clinic
• “The findings — reported in the American Journal of Physiology: Endocrinology and Metabolism — indicate that eating first actually helps the body burn more carbohydrates during exercise.” Medical News Today
• “We found that, compared to skipping breakfast, eating breakfast before exercise increases the speed at which we digest, absorb, and metabolize carbohydrate that we may eat after exercise.” Javier Gonzalez, PhD – Nutrient-Exercise Timing and Metabolic Health

Eating a mix of carbohydrates and other macronutrients before working out is grounded in science and can significantly impact your performance and results. Here’s why:

Carbohydrates as Fuel: Carbohydrates are the body’s preferred source of energy, especially during high-intensity exercise. Carb is broken down into glucose, which is then stored in your muscles and liver as glycogen. During exercise, your body taps into these glycogen stores to fuel your muscles, providing you with the energy needed to power through your workout.

Protein for Muscle Repair and Growth: Including protein in your pre-workout meal provides the necessary amino acids for muscle repair and growth. When you exercise, especially during resistance training, your muscles undergo stress and micro-tears. Protein before your workout ensures that your body has the building blocks it needs to repair and rebuild muscle tissue, ultimately leading to greater muscle strength and size over time.

Fats for Sustained Energy: While carbohydrates are the primary fuel source for high-intensity exercise, including healthy fats in your pre-workout meal can provide a source of sustained energy. Unlike carbs, which are quickly metabolized for energy, fats are broken down more slowly, providing a steady release of energy throughout your workout. This can help prevent energy crashes and keep you feeling fueled and focused during longer or more intense training sessions.

By including all three macronutrients in your pre-workout meal, you can optimize your energy levels, enhance muscle recovery, and ultimately get the most out of your workouts.

The Timing Dilemma: When to Eat?

Timing is crucial when it comes to pre-workout nutrition. Ideally, aim to eat a balanced meal/snack containing carbohydrates, protein, and fats 1-3 hours before exercising. This timing allows for optimal digestion and absorption of nutrients, ensuring that your body has enough energy to fuel your workout without feeling sluggish or weighed down by a heavy meal.

Examples of Pre-Workout Meals

Keep it simple. Think whole foods that provide sustained energy. Complex carbs like whole grains, fruits, and veggies are your go-tos. Pair them with lean proteins such as chicken, fish, or tofu for muscle repair and growth. Don’t forget healthy fats like nuts, seeds, or peanut butter to keep you feeling satisfied throughout your workout. Some ideas:

1. Toast topped with almond/peanut butter and banana slices (This is my staple)
2. Grilled chicken breast with rice and roasted vegetables.
3. Moong dal chilla with paneer stuffing
4. Brown rice with stir-fried paneer and vegetables

Hydration is as important as a pre-workout meal. Drink water before, during, and after your workout to stay hydrated and maintain peak performance. It might seem obvious, but it’s easy to forget the importance of hydration in the midst of your workout routine.

Before you even start exercising, it’s essential to ensure that you’re adequately hydrated. Dehydration can impair performance and lead to fatigue, dizziness, and even heat-related illnesses. Aim to drink water throughout the day leading up to your workout to ensure that you start your exercise session in a hydrated state. Sip water regularly throughout your workout, especially if you’re sweating heavily or exercising in hot or humid conditions.

In addition to water, electrolyte balance is essential during your workout. Electrolytes like sodium, potassium, and magnesium are lost through sweat and play a crucial role in hydration and muscle function. Consuming electrolyte-rich fluids or snacks, such as sports drinks or coconut water, can help replenish these electrolytes and support hydration during prolonged or intense exercise sessions.

At the end of the day, there’s no one-size-fits-all approach to pre-workout nutrition. Pay attention to how different foods make you feel and adjust accordingly. Whether you choose to eat before working out or not, the goal is the same: to fuel your body for success. So, next time you’re faced with the question of whether to eat before a workout, remember these simple guidelines and listen to what your body needs.
