How Much Protein Do You Actually Need?
Protein is the most talked-about macronutrient in fitness — and also the most misunderstood. Here is what the research actually says.
Your muscles are built from protein. When you train, you create small amounts of damage in the muscle fibers. Protein provides the amino acids your body uses to repair and reinforce that tissue — making it slightly larger and stronger over time. Without adequate protein, that repair process is compromised.
The current research consensus for people who train regularly is roughly 0.7–1.0 grams of protein per pound of bodyweight per day (about 1.6–2.2 g per kg). For a 170 lb person, that is 120–170 g of protein daily. Beginners and people in a calorie deficit benefit from being closer to the higher end.
Spreading protein across 3–4 meals is more effective than getting it all in one or two sittings. Your body can only use so much for muscle protein synthesis at one time — roughly 40–50 g per meal — before the rest gets used for energy or other functions.
Food sources matter. Whole food proteins (chicken, eggs, Greek yogurt, fish, beef, legumes) come with other nutrients and tend to be more satiating than protein shakes. Shakes are a convenient top-up, not a replacement. If you are hitting your protein target through real food, you probably do not need a supplement at all.
Calorie intake still trumps protein intake. If you are not eating enough total calories, your body will burn protein for energy rather than use it to build muscle. Get your calories right first, then dial in protein.
Bottom line: Aim for 0.7–1.0 g of protein per pound of bodyweight. Hit it through real food first, then supplement the gap if needed.
