To achieve his muscular, 225-pound physique for Batman v Superman: Dawn of Justice and Justice League, Ben Affleck committed to a rigorous dietary overhaul, working with renowned nutritionist Rehan Jalali. His goal was not simply to gain weight, but to build dense, functional muscle that would make him appear formidable in the iconic Batsuit. This meant adhering to a high-volume, high-protein diet with specific restrictions and careful macronutrient timing.
The Six-Meal Strategy
One of the cornerstones of the program was eating six smaller, nutrient-dense meals throughout the day. This approach kept his metabolism elevated, provided a constant supply of energy for intense workouts, and ensured his muscles received the fuel needed for repair and growth. Eating frequently also helped manage hunger and cravings, preventing overeating or resorting to unhealthy snacks. The focus was on whole foods, eliminating highly processed items to maximize nutritional benefit.
Macronutrient Breakdown
Affleck's diet was carefully balanced to fuel his intense training schedule. The macronutrient ratios were approximately 40% carbohydrates, 35% lean protein, and 25% essential fats. This balance ensured a steady energy supply from carbohydrates, crucial protein for muscle synthesis, and healthy fats for hormone production and overall health. On training days, his calorie intake was between 2,500 and 3,000, adjusted based on his activity level.
Key Components of Ben Affleck's Batman Diet
The foods included in the diet were meticulously chosen for their nutritional value. Here is a list of the staple ingredients:
- Lean Protein Sources: Crucial for muscle repair and growth, this included egg whites, chicken breast, salmon, and turkey. These were prepared by grilling or baking to avoid added fats.
- Complex Carbohydrates: To provide sustained energy, Affleck's diet featured steel-cut oatmeal, sweet potatoes, and fibrous vegetables. These slow-digesting carbs were strategically consumed around his workouts to maximize performance and replenish glycogen stores.
- Healthy Fats: Sources like flaxseed oil, avocados, and unsalted almonds supplied essential fatty acids. These were important for joint health and inflammation control, vital for a heavy training load.
- Low Sodium and No Dairy: The diet strictly limited sodium intake to 1,500–2,000 mg per day to avoid water retention and bloat. Dairy was also eliminated, as it didn't align with the strict macronutrient profile and could contribute to inflammation.
- Hydration and Supplements: In addition to ample water intake, Affleck utilized supplements such as whey protein powder and a CLA supplement to support muscle building and fat metabolism.
Sample Daily Meal Plan
To illustrate the structure of the diet, here is a typical day's eating schedule based on reports:
- Meal 1 (Breakfast): Egg whites, 1 cup oatmeal, banana, 1 tbsp flaxseed oil.
- Meal 2 (Snack): Whey protein shake and a handful of unsalted almonds.
- Meal 3 (Lunch): Grilled chicken breast, medium sweet potato, and steamed vegetables.
- Meal 4 (Pre-Dinner Snack): Protein bar and an apple.
- Meal 5 (Dinner): Grilled salmon or chicken breast with steamed broccoli and Brussels sprouts.
- Meal 6 (Late-Night Snack): A protein shake.
