What Alexander Skarsgård Ate to Transform for The Northman

Preparing Alexander Skarsgård for his role as Amleth in The Northman required more than grueling workouts. The foundation of his Viking transformation was built in the kitchen. Nutrition was just as crucial as training, ensuring that Alex not only looked the part but had the energy and stamina to perform physically demanding scenes day after day.

Why Nutrition is Essential in a Transformation

People often ask if training or nutrition is more important in transformations like this. The answer? Both are 100% essential. You can’t out-train a poor diet, and no matter how hard you work in the gym, it won’t show without proper fuel. For Alex’s journey, his diet evolved through three key phases: the bulk-up phase, the cutting phase, and the maintenance phase. Each phase required a different nutritional strategy to achieve specific goals.

Bulk-Up Phase: Building Viking Strength

In the bulk-up phase, Alex aimed to pack on muscle mass. This required eating in a calorie surplus, with plenty of protein for muscle-building and a balanced mix of fats and carbs for energy. Here’s a breakdown of his daily macronutrient intake:

• Calories: Around 3,700 per day

• Protein: 200 grams

• Carbs: 450 grams

• Fat: 150 grams

This phase wasn’t about staying lean—it was about fueling growth. By keeping body fat levels stable while maximizing muscle gain, Alex laid the foundation for his Viking physique.

A Typical Day of Eating

During the bulk-up phase, Alex followed a consistent meal schedule, eating five meals a day spaced roughly three hours apart. Here’s an example of what a day might look like:

1. Breakfast

• A hearty omelet made with 4-5 eggs

• Potatoes for slow-digesting carbs

• Avocado for healthy fats

• A mix of vegetables for micronutrients

2. Mid-Morning Snack

• A protein shake or lean meat

• Some nuts or a small serving of fruit

3. Lunch

• Grilled chicken or lamb

• Chickpeas or quinoa for carbs

• A mix of steamed vegetables

4. Afternoon Snack

• Cottage cheese or a small serving of fish

• Whole-grain crackers or thin crisp bread

5. Dinner

• Ribeye steak or salmon

• Roasted potatoes or farro

• Asparagus, broccoli, or another vegetable blend

Timing was also crucial. One of Alex’s meals was always scheduled post-workout to optimize recovery and muscle repair.

Cutting Phase: Sculpting the Viking Physique

After building mass, Alex transitioned into the cutting phase. Here, the goal was to reduce body fat while preserving as much muscle as possible. This required lowering overall calorie intake while maintaining high protein levels. Meals were still nutrient-dense but became slightly smaller, with more focus on lean proteins and vegetables.

Maintenance Phase: Staying Viking-Ready

The maintenance phase was perhaps the most challenging. During the five to six months of filming, Alex’s diet had to sustain his energy levels and keep him looking Viking-strong. Long days on set, stunt work, and physical exertion made it critical to avoid under-eating or over-eating. Careful monitoring ensured Alex had enough fuel to perform without compromising his hard-earned physique.

The Role of Macronutrients

Understanding the balance between protein, fats, and carbs was key to Alex’s success:

• Protein: Essential for muscle repair and growth. Main sources included eggs, chicken, beef, fish, and seafood.

• Carbs: Provided the energy needed for intense training and long filming days. Carbs came from rice, potatoes, quinoa, and even thin crisp bread.

• Fats: Supported hormone health and added calorie density. Fats came from avocados, nuts, fish oil, and olive oil.

The Importance of Quality Foods

Calories aren’t created equal. Alex’s diet focused on whole, nutrient-dense foods like salmon, vegetables, and high-quality grains. While it’s possible to hit calorie goals with junk food, the lack of micronutrients and the impact on energy and recovery make it a poor choice. Clean eating was non-negotiable for Alex’s transformation.
