How much protein do I actually need per day?
Just started lifting. My gym bro says I need 200g protein a day. That seems like an insane amount. I'm 170 lbs and can barely get 80g from normal eating. What's the real number?
The evidence-based recommendation for muscle building: 0.7-1g per pound of bodyweight. For you at 170 lbs: 120-170g daily.
200g is overkill. Won't hurt you, but won't give additional benefits over 170g. Your gym bro is giving the classic bro-science overestimate.
The minimum effective dose for most lifters is about 0.7g/lb. Going higher provides diminishing returns.
At 170 lbs, aim for 140-170g. The "1g per lb" rule is a slight overestimate but easy to remember and won't hurt. Don't stress about hitting it exactly — even 120g is light years ahead of the average American's ~60g.
Going from 80g to 140g will make a HUGE difference. Practical ways to add protein:
- Add Greek yogurt (20g) to breakfast
- Double the meat in your lunch (15-20g extra)
- Protein shake (25g)
That's 60-65g extra right there with minimal effort.
200g is gym bro territory. It's not dangerous but you'll spend a lot more time and money chasing those last 30-40g for minimal extra benefit. 1g/lb is the sweet spot.
The research is clear: there's no additional muscle protein synthesis benefit above about 1.6g/kg (0.73g/lb) for most people. Going to 1g/lb is insurance, going to 1.2g/lb is paranoia.
If you're eating plant-based, aim for the higher end (1g/lb) to account for lower digestibility. Animal protein eaters can be fine at 0.7-0.8g/lb.
140g seems way more doable than 200g. I'll aim for that and add a shake + Greek yogurt to my routine. Thanks for the realistic advice!
As a beginner lifter, you're in the golden period of "newbie gains." Your body is primed to build muscle. Just get the protein in and lift consistently. Don't overthink the rest.
coming back to this thread because i was in the exact same boat. ended up landing at about 150g/day at 165 lbs and that's been the sweet spot — enough to recover, not so much that every meal is just chicken.
also worth saying — hitting protein consistently matters way more than hitting an exact number. 130g every day beats 180g monday and 70g the rest of the week
