Tariq had the number memorised.
75 kilograms bodyweight. 0.8 grams per pound. He'd done the conversion three times to make sure. 132 grams of protein per day. He hit it. Consistently. For two months straight.
And yet the muscle side of his recomposition was barely moving. Fat was coming off, slowly. Strength wasn't climbing. Body shape wasn't shifting the way he'd expected.
He wasn't getting the answer wrong. He was getting the wrong answer. The 0.8g/lb figure he'd memorised was the minimum for general health — not the threshold for protein intake during body recomposition. Those are different numbers, and the gap between them explains a lot of stalled progress.
How Much Protein You Actually Need for Body Recomposition
The number that appears in most articles — 0.8g per pound, or roughly 1.76g per kilogram — is frequently cited as the body recomposition target. It's not. That figure originates from general dietary reference values for sedentary adults trying to avoid muscle loss, not for people actively training to build muscle while losing fat simultaneously.
The research-supported range for body recomposition specifically is 1.6 to 2.2 grams of protein per kilogram of bodyweight daily. A 2017 position stand in the Journal of the International Society of Sports Nutrition — reviewing 49 studies on protein and body composition — concluded that 1.6g/kg represents the point at which muscle protein synthesis is meaningfully supported, with diminishing returns above 2.2g/kg for most people.
In practice, aim for 1.8 to 2.0g/kg as a daily working target. Not because 1.6g/kg doesn't work — it does — but because real-world tracking has variance. Some days you'll be slightly under. Targeting 1.8g/kg means your worst days still clear the 1.6g/kg floor.
For a 70kg person, that's 126 to 140 grams daily. For an 85kg person, 153 to 170 grams. Not 68 grams. Not 100 grams. The gap between what most people are eating and what recomposition requires is usually 40 to 60 grams per day — and that gap is the entire reason the muscle-building half of recomposition stalls. *(See: Best macros for body recomposition)*
Why That Number — Not Just "More Is Better"
Protein isn't stored the way fat and carbohydrates are. Excess protein beyond what the body can use for tissue repair and synthesis gets oxidised for energy — it doesn't accumulate as muscle. So "more is always better" is wrong. There's a ceiling.
The mechanism matters here. Muscle protein synthesis — the process by which your body actually builds new muscle tissue — is driven by the availability of essential amino acids, particularly leucine. Leucine acts as a trigger. When leucine concentration in the blood crosses a certain threshold, it signals the mTOR pathway to initiate muscle building. Below that threshold, the signal is weaker and synthesis is submaximal, regardless of training quality.
A single meal needs roughly 2 to 3 grams of leucine to trigger a maximal synthetic response, according to research covered by the American Journal of Clinical Nutrition. That typically corresponds to 25 to 40 grams of complete protein per meal — which has direct implications for how you distribute protein across the day, not just how much you eat in total.
But here's what nobody tells you: the ceiling for total daily protein during a calorie deficit is higher than during maintenance. When calories are restricted, the body increases protein oxidation for energy. More protein is "used up" as fuel, meaning less is available for muscle synthesis at any given intake level. This is why recomposition protein targets run higher than standard maintenance recommendations — the deficit itself raises the requirement. *(See: Body recomposition: calorie deficit or maintenance?)*
Timing: Does It Actually Matter?
Less than people think. More than people dismiss.
The "anabolic window" — the idea that you must consume protein within 30 minutes post-training or the session was wasted — has been largely debunked. A meta-analysis published in the Journal of the International Society of Sports Nutrition found that total daily protein intake matters far more than the timing of any individual meal.
That said, two timing factors do have practical relevance.
Pre-training protein — a meal containing 25 to 40g of protein two to three hours before training — ensures amino acids are circulating during the session and in the immediate recovery period after. It removes the need to rush a post-workout shake. For most people, this just means not training fasted on an empty stomach past 5pm after a light lunch.
Pre-sleep protein is the more interesting one. A 2015 study reviewed by Medicine & Science in Sports & Exercise found that 40 grams of casein protein consumed before sleep increased overnight muscle protein synthesis by around 22% compared to a placebo. Slow-digesting protein — casein from cottage cheese, Greek yoghurt, or plain curd — maintains elevated amino acid levels throughout the overnight fast, when the body is doing most of its repair work.
Practically: if your pre-sleep snack is going to be something anyway, make it a protein-containing one. The rest of the timing is largely secondary to total daily intake.
Protein Sources That Work in Real Life
Chicken breast is the default. It's also the one people get bored of fastest, which is why protein targets collapse around week five for so many people.
Here's what 30 grams of protein actually looks like across different foods — not per 100 grams, but as a portion you'd actually eat:
100g cooked chicken breast: ~31g protein, ~165 calories
2 large eggs + 3 egg whites: ~27g protein, ~200 calories
200g low-fat Greek yoghurt: ~20g protein, ~130 calories
150g cooked lentils (masoor dal): ~14g protein, ~175 calories
100g canned tuna in water: ~25g protein, ~110 calories
30g whey protein powder: ~24g protein, ~120 calories
150g paneer: ~27g protein, ~375 calories
Two things stand out from that list. First, dairy — particularly Greek yoghurt, cottage cheese, and paneer — is genuinely protein-dense and far more varied than people treat it. Second, plant proteins like lentils and chickpeas are real contributors but require meaningfully larger portions to hit the same gram count, and they come with more calories attached. For vegetarian recomposition, this isn't a dealbreaker — it just requires planning. *(See: Body recomposition meal plan on a budget)*
Complete vs incomplete protein matters over the long term. Animal proteins and soy contain all nine essential amino acids, including adequate leucine. Many plant proteins are low in one or more essential amino acids. Combining different plant sources — rice and lentils, for instance — over the course of a day covers this gap without requiring obsessive meal planning.
Spreading Protein Across the Day
Getting 160 grams of protein in two meals is theoretically possible. It's also not how the body handles it most efficiently.
Each meal triggers a discrete muscle protein synthesis response. That response peaks and plateaus — adding more protein to a single meal beyond roughly 40g doesn't proportionally increase synthesis. The body can use it, but you get more total synthesis from three to four 35–45g protein meals than from two 75g protein meals at the same daily total.
The practical setup for most people: three main meals each containing 35 to 50 grams of protein, with an optional pre-sleep protein snack of 20 to 40 grams. That covers 145 to 190 grams total — enough to comfortably land in the 1.8 to 2.0g/kg range for most body weights.
Skipping breakfast, training fasted, and then trying to catch up on protein across two later meals is harder to execute than it sounds. Not impossible. But harder. If your protein is consistently falling short, meal distribution is often where the gap lives.
The Gap Most People Don't See
People who think they're hitting protein targets are usually about 30 to 50 grams below actual target. Every time. Not because they're lying — because protein is genuinely difficult to estimate accurately without measuring.
A "large" chicken breast in a restaurant might be 120 grams cooked or 200 grams cooked. The protein difference is 17 grams. A serving of dal at a household lunch might be 150ml or 300ml depending on the day. Two tablespoons of peanut butter eyeballed versus measured can vary by 10 grams of fat and 4 grams of protein. None of these seem significant individually. Over three meals daily for eight weeks, the cumulative effect on muscle protein synthesis is very significant.
Honestly, one week of actually weighing food — not permanently, just one diagnostic week — tells most people more about their protein reality than months of estimation.
Protein intake for body recomposition comes down to three things: the right target in grams (not pounds, not percentages), enough meals to distribute it effectively across the day, and sources varied enough that you'll actually keep eating them week after week. Get those three right, and the muscle side of recomposition has what it needs to run. *(See: Body recomposition not working? 7 real reasons)*
Protein Checklist: Target 1.8–2.0g per kg bodyweight daily. Spread across 3–4 meals of 30–45g each. Include a slow-digesting protein source (curd, paneer, Greek yoghurt) before sleep. Use varied sources to avoid the consistency collapse that hits around week five. Track for at least one week to verify you're actually hitting the number — not estimating it.
Frequently Asked Questions
How much protein per day for body recomposition?
1.6 to 2.2 grams per kilogram of bodyweight, with 1.8 to 2.0g/kg as a practical working target. For a 70kg person that's around 126 to 140 grams daily. For an 80kg person, 144 to 160 grams. This range is higher than general dietary recommendations because the calorie deficit used in recomposition increases the amount of protein oxidised for energy, raising the threshold needed to support muscle protein synthesis.
Does protein timing matter for body recomposition?
Total daily intake matters most. But two timing points have real evidence behind them: pre-training protein (25–40g in the 2–3 hours before a session) and pre-sleep protein (casein-type sources like curd or cottage cheese), which has been shown to increase overnight muscle synthesis. Outside of those, distributing protein across 3–4 meals is more valuable than any specific timing window.
Can I hit my protein target from plant sources only?
Yes, with planning. Plant proteins are generally lower in leucine per gram and often incomplete in essential amino acid profile. Combining sources across the day (lentils, chickpeas, tofu, soy, quinoa, dairy if vegetarian) covers the amino acid gaps. Portions will need to be larger than equivalent animal protein servings to hit the same gram totals — which means more calories attached to the protein, requiring calorie targets to be set accordingly.
Is a protein supplement necessary?
No. Whole food sources cover the target for most people. Where supplements earn their place: when protein from food alone is consistently falling short due to appetite, schedule, or preference, whey or casein protein powder is the most efficient calorie-per-gram option available. Not necessary. Often practical.
What happens if I eat too much protein during recomposition?
Above roughly 2.4g/kg, you're mainly adding calories without a proportional increase in muscle synthesis benefit. The excess protein gets oxidised for energy. It won't hurt you, but it does leave fewer calories available for carbohydrates — which matters for training performance and progressive overload. Extremely high protein intakes on very low total calories can also strain kidney filtration over time, though this is primarily a concern at clinical extremes, not typical recomposition ranges. *(See: Best macros for body recomposition)*
