What should you eat before a workout - and why post-workout nutrition is equally important

You train hard. You give your all in the gym. Yet one question often determines progress or stagnation: What do you actually eat before and after your workout?

Many focus exclusively on the workout itself. However, your performance, muscle growth, and fat loss are significantly influenced by your nutrition surrounding the workout.

In this blog, you will learn, based on scientific evidence, what you should eat before the workout, what truly counts during the post-workout window, and how to optimally combine both.

Why Pre- and Post-Workout Nutrition is so Important

Training is a stimulus. Nutrition is the response to it.

During training:

• muscle glycogen stores are depleted
• micro-injuries occur in the muscles
• energy consumption increases
• the need for amino acids rises

Without appropriate nutrition, you hinder your recovery — and thus your progress.

Studies show that especially the intake of proteins and carbohydrates around the workout significantly influences muscle protein synthesis (research by Brad Schoenfeld, among others).

What Should You Eat BEFORE the Workout?

The Goal of the Pre-Workout Meal

• Provide energy
• Prevent muscle breakdown
• Enhance performance
• Improve focus

1️⃣ Carbohydrates — Your Fuel

Carbohydrates fill your glycogen stores. Without them, your training performance measurably drops.

Particularly suitable:

• Oatmeal
• Rice
• Banana
• Whole grain bread
• Potatoes

Why? Glycogen is the primary energy source during intense strength training.

2️⃣ Protein — Protection for Your Muscles

Protein before the workout ensures that your body breaks down less muscle protein during training.

Ideal:

• Eggs (fits well with your dietary style 😉)
• Chicken
• Yogurt
• Whey protein

20–40 g of protein is optimal.

3️⃣ Fat — Use Sparingly

Too much fat slows digestion. Keep it moderate before the workout.

Timing — When to Eat?

And Now: Post-Workout — The Underestimated Window

Many speak of the “anabolic window.” The truth: It's larger than previously thought — but still relevant.

Goals After the Workout

• Refill glycogen stores
• Maximize muscle protein synthesis
• Initiate recovery
• Lower cortisol levels

Protein After the Workout

After the workout, your muscles are particularly receptive to amino acids.

30–40 g of high-quality protein is ideal. Whey protein is especially effective because it is quickly digested.

Carbohydrates After the Workout

Especially useful:

• if you train again on the same day
• if you want to build muscle
• if you trained intensively

Good options:

• Rice
• Potatoes
• Fruits
• Dates

Do You Really Need a Shake?

No.

A regular meal with:

• A protein source
• Carbohydrates
• Some vegetables

is entirely sufficient. Shakes are merely convenient — not magical.

Muscle Building vs. Fat Loss — Are There Differences?

Muscle Building

• More carbohydrates around the workout
• Caloric surplus
• Keep protein consistently high

Fat Loss

• Carbohydrates strategically around the workout
• Caloric deficit
• High protein (2–2.5 g/kg body weight)

Especially if you – as you once mentioned – struggle with less appetite, it's wise to place the most important calories directly around your workout.

Common Mistakes

❌ Training on an empty stomach and wondering why performance declines

❌ Eating too fatty before the workout

❌ Not eating after the workout

❌ Not eating for 5 hours post-workout

Example of an Optimally Structured Training Day

2–3 Hours Before the Workout:

• Rice or potatoes
• Chicken, fish, or eggs
• Vegetables

Immediately After the Workout:

• Whey protein or a protein-rich meal
• A quick carbohydrate source (e.g., banana or rice)

1–2 Hours Later:

• Complete meal with protein, complex carbohydrates, and healthy fats

Conclusion

Training without proper nutrition is like a car without gasoline.

The key points:

• Before training: Carbohydrates + Protein
• After training: Prioritize protein
• Timing is important — but don't obsess over it
• Consistency beats perfection
