How Much Protein Do You Need Per Day?
Protein is essential for building muscle, producing enzymes and hormones, and supporting immune function. Daily protein needs depend on your body weight and fitness goals. The minimum recommended for sedentary adults is 0.8g per kg of body weight. For muscle building, 1.6–2.2g/kg is the evidence-based range. During weight loss, higher protein intake (1.2–1.6g/kg) helps preserve lean muscle mass.
Timing also matters — consuming 20–40g of protein within 30–120 minutes after resistance training maximizes muscle protein synthesis. Spreading protein intake across meals (rather than one large dose) improves absorption efficiency. Whole food sources like eggs, chicken, fish, and legumes are excellent protein options.
Frequently Asked Questions
For healthy adults, consuming above the recommended range for short periods is generally safe. However, those with kidney disease should consult a doctor before increasing protein intake significantly.
