Protein for Bodybuilding: How Much to Build Mass
Bodybuilders typically eat 1.6-2.2 g of protein per kg of body weight per day, and up to 2.4 g/kg when cutting for a show. For a 90 kg (198 lb) bodybuilder that is around 145-200…
Calculate Your Protein IntakeMuscle protein synthesis is maximised by both adequate total protein and a resistance-training stimulus. Going far beyond 2.2 g/kg rarely adds muscle faster, but a slightly higher intake during a cut helps protect hard-earned mass while calories are low.
Distribution is a genuine lever for bodybuilders: four to five meals of 30-50 g each keep muscle protein synthesis elevated throughout the day. Anchor most meals around lean meat, fish, eggs and dairy, and use whey or a plant blend around training to hit your numbers.
- Off-season growth: 1.6-2.2 g/kg per day
- Contest prep or cut: up to 2.4 g/kg to spare muscle
- 4-5 meals of 30-50 g spread across the day
- Progressive resistance training is required to use the protein
Quick Reference
- General health (sedentary): 0.8–1.0 g/kg body weight
- Weight loss: 1.6–2.2 g/kg to preserve muscle in a deficit
- Muscle gain: 1.8–2.5 g/kg depending on training experience
- Athletic performance: 2.0–3.1 g/kg
- Spread intake across 4–5 meals of 25–40g each for best results
