Best Time to Eat Protein: Timing, Spacing and Workouts
Total daily protein matters far more than timing, but spreading it across 3–4 meals of 25–40 g each — including one within a few hours of training — gets the most muscle protein…
Calculate Your Protein IntakeStudies comparing protein timing consistently find that total daily intake is the strongest driver of muscle growth and retention. The post-workout “anabolic window” is much wider than once believed — eating protein within a couple of hours before or after training works about equally well.
Distribution still helps: muscle protein synthesis is maximized around 0.4 g/kg per meal, roughly 25–40 g for most people. Spreading intake over 3–4 meals, adding protein at breakfast where most people eat the least, and taking 20–40 g of slow-digesting protein such as casein or Greek yogurt before bed round out an evidence-based routine.
- Hit your daily total first — timing is a refinement, not the foundation
- Aim for 25–40 g of protein per meal, 3–4 times a day
- Eat a protein-rich meal within ~2 hours before or after training
- Slow protein (casein, Greek yogurt) before bed supports overnight recovery
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
