Estimate your daily protein requirements based on body weight and activity level
Protein is essential for muscle repair, enzyme production, immune function, and overall health. This calculator estimates your daily protein needs based on your body weight and activity level using widely accepted recommendations from sports nutrition and dietary guidelines. Different activity levels require different protein intakes to support muscle recovery and growth.
Daily protein needs are calculated by multiplying your body weight in kilograms by a protein factor based on your activity level. The standard range is from 0.8 g/kg for sedentary individuals up to 2.0 g/kg for bodybuilders and elite athletes.
For healthy individuals, high protein intake is generally safe, though extremely high levels (above 2.5 g/kg) may cause digestive discomfort and are unnecessary for muscle building. People with kidney disease should consult a doctor before significantly increasing protein intake.
While the post-workout anabolic window was once thought to be very narrow (30-60 minutes), current research shows that total daily protein intake and even distribution across meals matter more than exact timing. Consuming protein within a few hours after exercise is sufficient for most people.
