How Much Protein to Build Muscle: The Evidence-Based Answer
The supplement industry says 2g per pound. The science says 0.8-1.0g. Here is what actually works.
The evidence-based range for muscle building: 0.7-1.0 grams of protein per pound of body weight per day. A 170-pound person needs 120-170g daily. Meta-analyses consistently show that protein intake above 1.0g per pound provides no additional muscle-building benefit — it is simply expensive urine.
Hitting Your Target Without Supplements
Breakfast: 3 eggs + Greek yogurt = 36g. Lunch: chicken breast sandwich = 40g. Snack: cottage cheese or protein bar = 20g. Dinner: salmon fillet + rice = 38g. Total: 134g. Cost: approximately $10-12 for the day. Whole food sources are cheaper per gram of protein than supplements and provide additional nutrients.
When Protein Shakes Make Sense
When you cannot eat enough whole food (busy schedule, low appetite after training). As a convenient breakfast option when cooking is not possible. When hitting 140g+ daily from food alone feels like a chore. One shake per day (25-30g) is the sweet spot. More than two per day means your diet needs restructuring, not more powder.
