Is it better to eat more when working out?

•
6 min read

According to a study published by the University of Maryland Medical System, simply telling people to "eat less and move more" for weight loss often falls short. To achieve sustainable and effective results, a better understanding of nutrition is required. This raises a crucial question: is it better to eat more when working out?

Quick Summary

The debate over whether to eat more when working out depends heavily on your specific goals. For muscle gain, a calorie surplus with adequate protein and carbs is key. For fat loss, a slight deficit is necessary, but the right nutrient timing and composition are crucial to prevent muscle loss. Combining mindful nutrition with exercise is the most effective approach for sustainable, long-term health.

Key Points

  • Goals Dictate Intake: Whether you should eat more depends on your fitness objective. Muscle gain requires a caloric surplus, while fat loss necessitates a deficit.

  • Strategic Fueling is Key: Focus on intelligent, not just increased, eating by prioritizing nutrient-dense foods and timing your meals around workouts for optimal performance and recovery.

  • Carbs Power Workouts: Carbohydrates are the main energy source, crucial for high-intensity exercise and replenishing glycogen stores for better recovery.

  • Protein Repairs Muscles: Higher protein intake is necessary for active individuals to repair and rebuild muscle tissue broken down during exercise.

  • Timing Enhances Results: Consuming a balanced mix of carbs and protein 30-60 minutes before and after a workout, respectively, can maximize energy and muscle repair.

  • Don't Forget Hydration: Proper fluid intake before, during, and after exercise is vital for preventing dehydration and supporting overall performance.

  • Quality Over Quantity: The quality of your calories matters just as much as the quantity. Prioritize whole foods over processed options for sustained energy and better health.

  • Consistency is Crucial: Long-term, sustainable results come from consistent, mindful nutrition combined with regular exercise, not from extreme or erratic eating patterns.

For anyone starting a fitness journey, the question of diet is as critical as the workout itself. The simple formula of "eat less, move more" proves insufficient for many, leading to confusion and inconsistent results. The truth is more nuanced, and the answer to whether it's better to eat more when working out is highly dependent on your individual fitness goals.

The Role of Calories and Macronutrients

To understand this, we must first look at the basics of energy balance. Your body requires energy, measured in calories, to function and fuel physical activity. The macronutrients—carbohydrates, protein, and fats—provide this energy and the building blocks for repair and growth.

Calorie Goals for Different Objectives

  • For muscle gain (bulking): To build muscle, you need to be in a caloric surplus, meaning you consume more calories than you burn. This provides the extra energy and nutrients needed for muscle protein synthesis, the process of repairing and building muscle tissue. A modest surplus of 350 to 500 calories per day is often recommended to gain muscle without excessive fat gain.
  • For fat loss (cutting): To lose fat, you must be in a caloric deficit, burning more calories than you consume. A common approach is to subtract 500 calories from your daily maintenance level to lose about a pound of fat per week. However, an excessive deficit can lead to muscle loss.
  • For body recomposition: This is the process of losing fat and gaining muscle simultaneously. It's a challenging but achievable goal, especially for those new to resistance training. A small caloric deficit of 100-200 calories per day, combined with a high protein intake, can support this.

The Importance of Macronutrients

  • Carbohydrates: These are the body's primary fuel source, especially during moderate to high-intensity exercise. Carbohydrates are stored as glycogen in your muscles and liver, and consuming enough is vital for maintaining high performance and replenishing energy stores after a workout. For individuals exercising at moderate intensity, 5-7g of carbohydrates per kg of body weight per day is recommended.
  • Protein: Often called the building blocks of muscle, protein is essential for repairing and rebuilding muscle tissue that is broken down during exercise. A higher intake is often required for active individuals, with recommendations ranging from 1.2 to 2.0 g per kg of body weight daily. Spacing protein intake evenly throughout the day can optimize muscle repair.
  • Healthy Fats: While not the primary fuel for high-intensity exercise, healthy fats are crucial for overall health and provide sustained energy for endurance activities. Including sources like nuts, seeds, and avocados helps with inflammation and provides essential fatty acids.

Timing Your Nutrient Intake Strategically

When you eat can be as important as what you eat. Strategic nutrient timing can enhance performance and recovery.

  • Before a Workout: A meal 2-3 hours before exercising should focus on carbohydrates for energy and some protein for muscle support. This prevents sluggishness and ensures your body has fuel for sustained effort. If time is limited, a small, easy-to-digest carb snack like a banana 30-60 minutes before is effective.
  • During a Workout: For workouts longer than 60 minutes, especially high-intensity ones, consuming 30-60 grams of carbohydrates per hour can help maintain performance and delay fatigue. Options include sports drinks, gels, or fruit.
  • After a Workout: This is a critical recovery window. Within 30-60 minutes post-exercise, consuming a combination of carbohydrates and protein helps replenish muscle glycogen stores and initiate muscle repair. The carbohydrates stimulate insulin, which helps shuttle nutrients into the muscle cells, while the protein provides the necessary amino acids. A ratio of 2:1 or 3:1 carbs to protein is a good starting point.

Comparison: Eating More vs. Eating Intelligently When Working Out

Feature Eating More (Indiscriminately) Eating Intelligently (Based on Goals)
Calorie Focus Uncontrolled calorie increase, often from poor food choices. Calorie intake is precisely calculated for surplus (muscle gain) or deficit (fat loss).
Macronutrient Balance Imbalanced macros; excess fat and sugar. Optimized ratio of carbs, protein, and healthy fats.
Effect on Goals Can lead to significant fat gain alongside muscle gain (dirty bulking) or muscle loss during a calorie deficit. Maximizes muscle gain and minimizes fat gain during bulking; preserves muscle during fat loss.
Energy Levels Highs and lows due to simple sugar intake, potential for feeling sluggish. Stable and sustained energy throughout workouts and the day, preventing crashes.
Nutrient Timing No strategic timing; food is consumed randomly. Nutrients are timed before and after workouts for enhanced performance and recovery.
Body Composition Less control over body fat percentage; risk of metabolic issues. Better body recomposition results, leading to a leaner, more muscular physique.
Long-Term Sustainability Often unsustainable due to restrictive nature or unhealthy habits. Highly sustainable as it focuses on balanced, wholesome foods and consistent habits.

The Power of Whole Foods and Hydration

While macronutrient ratios are important, the source of your calories is equally crucial. A diet rich in whole foods—lean proteins, whole grains, fruits, and vegetables—provides the micronutrients and fiber necessary for optimal performance and health. These foods offer more sustained energy and better satiety than processed foods.

Hydration is another non-negotiable aspect of fuelling your workouts. Dehydration can severely impact endurance and cognitive function. The American College of Sports Medicine recommends drinking 2-3 cups of water in the hours before a workout and sipping water regularly during exercise. For extended sessions, a sports drink can help replenish electrolytes.

Conclusion: Fuel Your Body Wisely, Not Just More

It is not simply about eating more when working out, but about eating smarter. The optimal approach depends entirely on your specific goals, whether that is muscle gain, fat loss, or body recomposition. By strategically managing your calorie intake, balancing your macronutrients, timing your meals, and focusing on nutrient-dense whole foods, you can effectively support your fitness efforts. Listening to your body and making informed nutritional choices is the most powerful tool for maximizing performance, recovery, and long-term health.

Frequently Asked Questions

Not necessarily. While a caloric surplus is needed to build muscle, simply eating more without focusing on protein intake and resistance training can lead to excess fat gain. The key is a strategic surplus with adequate protein.

Aim to consume a meal or snack containing both carbohydrates and protein within 30-60 minutes after your workout. This time frame, often called the 'anabolic window,' is ideal for replenishing glycogen stores and repairing muscle tissue.

For an intense workout, a pre-workout meal 2-3 hours beforehand should include carbohydrates for energy and a moderate amount of protein. Examples include whole-grain toast with peanut butter or a chicken and rice dish.

Body recomposition (losing fat and gaining muscle) is possible but challenging. It requires a small caloric deficit (100-200 calories) paired with a high protein intake and consistent resistance training, not an overall increase in calories.

For low-intensity exercise, it may be fine, but for moderate to high-intensity training, working out fasted can lead to reduced performance, lightheadedness, and lethargy. Fueling with carbohydrates beforehand is generally recommended for better results.

For active individuals, the recommended protein intake is higher than for sedentary people. A range of 1.2 to 2.0 grams of protein per kilogram of body weight is often suggested to support muscle repair and growth.

During exercise, your body loses fluids through sweat, which can negatively impact performance and cause fatigue. Staying well-hydrated throughout the day and during your workout is critical for regulating body temperature and transporting nutrients.
