Bodybuilding nutrition fundamentals

Nutrition represents 70% of your bodybuilding results. Without proper nutrition, even the best training program won't yield optimal results. The three pillars are: calorie intake adapted to your goal, enough protein for muscle synthesis, and carbohydrates for energy.

Calories: the determining factor

When bulking, aim for a surplus of 300-500 kcal above your maintenance. When cutting, a deficit of 400-600 kcal allows you to lose fat while preserving muscle. For maintenance, stay at your TDEE. The precision of your calorie intake directly determines your results.

Macronutrients in detail

Protein (1.6-2.2g/kg): essential for muscle building and repair. Carbohydrates (3-6g/kg): fuel for training and recovery, promote protein synthesis via insulin. Fats (0.8-1.2g/kg): necessary for hormones and vitamin absorption.

Nutritional periodization

Your nutrition should evolve with your goals. Alternate between bulking phases (6-12 months) and cutting phases (2-4 months). Some practitioners prefer continuous lean bulking. The key is tracking to adjust based on your progress.

Important

Never go below 1200 kcal/day (women) or 1500 kcal/day (men) without medical supervision. Too aggressive a deficit can be dangerous for your health and counterproductive for weight loss.

Complete Guide to Bodybuilding Nutrition

Nutrition is the often-neglected pillar of bodybuilding. This guide gives you all the keys to optimize your diet based on your goal: bulking, cutting, or body recomposition.

The Phases of Bodybuilding Nutrition

Bulking Phase

  • Goal: Maximize muscle growth
  • Calories: Maintenance + 300-500 kcal
  • Protein: 1.6-2.0g/kg
  • Carbohydrates: 4-6g/kg
  • Fats: 0.8-1g/kg
  • Typical duration: 6-12 months

Cutting Phase

  • Goal: Lose fat while preserving muscle
  • Calories: Maintenance - 400-600 kcal
  • Protein: 2.0-2.4g/kg (higher to preserve muscle)
  • Carbohydrates: 2-4g/kg
  • Fats: 0.7-1g/kg
  • Typical duration: 8-16 weeks

Maintenance / Recomposition

  • Goal: Maintain or improve body composition
  • Calories: Maintenance (TDEE)
  • Protein: 1.8-2.0g/kg
  • Carbs and fats: Based on preference

Nutrient Timing

Pre-workout (2-3h before)

  • Mixed meal with complex carbs and protein
  • Example: 150g rice + 150g chicken + vegetables

Post-workout (within 2-3h)

  • Carbohydrates to replenish glycogen
  • Protein for muscle synthesis
  • Example: 60g oats + 40g whey + banana

Before bed

  • Slow-digesting protein (casein)
  • Example: 200g Greek yogurt

Useful Supplements

  1. Whey protein: Convenient for hitting protein targets
  2. Creatine monohydrate: 3-5g/day, improves strength and muscle volume
  3. Vitamin D: If sun exposure is insufficient
  4. Omega-3: If fatty fish consumption is insufficient
