How Much Protein Per Day? The Real Answer
No question comes up more in coaching than this one. And the answer is simpler than the internet would have you believe. Let me cut through the noise.
The Number
0.8–1g of protein per pound of bodyweight per day. That's the target for anyone serious about body composition — fat loss, muscle building, or recomp. If you weigh 175 lbs, you're aiming for 140–175g of protein daily.
The research supports this range. Studies on protein and muscle protein synthesis consistently show that intakes above 0.7g/lb start diminishing in additional benefit, but staying at 0.8–1g gives you a comfortable buffer and accounts for real-world compliance (you won't hit it exactly every day).
Why Most People Are Way Under
The average American eats around 80–100g of protein per day. For a 175 lb person trying to build muscle or lose fat, that's roughly half of what they need. The result: slower muscle growth in a bulk, significant muscle loss in a cut, and poor recovery between sessions.
The fix is simple but requires intentionality. Protein doesn't happen by accident — you have to plan for it.
My rule for every client: build every meal around a protein source first. Figure out the protein, then add carbs and fat around it. Never the other way around.
Best Sources
Chicken breast, lean beef, eggs and egg whites, Greek yogurt, cottage cheese, white fish (tilapia, cod), salmon, shrimp, and whey protein powder for convenience. These are the highest protein per calorie options that most people will actually eat consistently.
Whey protein is not magic — it's just convenient. If your whole food protein sources are solid, you don't need it. If you're struggling to hit your number from food, a shake or two per day fixes that easily.
Timing: Mostly Irrelevant
The anabolic window is real but massively overstated. Research shows that total daily protein matters far more than when you eat it. That said, spreading your intake across 3–4 meals with 30–50g of protein per meal does maximize muscle protein synthesis across the day. Practically: eat protein at breakfast, lunch, dinner, and add a snack if needed.
Over 40: Slightly More Is Better
After 40, muscle protein synthesis efficiency decreases slightly — your muscles become less sensitive to the protein signal. Staying at the higher end of the range (closer to 1g/lb) and ensuring you have 40–50g of protein in at least one meal per day (rather than spreading it too thin) helps compensate.
