“How much protein should I be eating?”
Standard answer from most sources: “0.8g per kilogram of bodyweight.”
That’s the RDA for sedentary people to avoid deficiency. Not for building muscle. Not even close.
After a decade programming nutrition for clients trying to build muscle, I’ve learned that protein intake makes or breaks progress more than any other single nutritional factor.
Get it right, and training produces visible results. Get it wrong, and you’ll train perfectly whilst staying exactly the same.
Here’s what actually works—based on real clients, real tracking, real results. Not theoretical optimization from studies that don’t account for real-world variables.
The Numbers That Actually Matter
Let’s cut through the confusion with specific targets based on what’s worked with hundreds of clients.
For Building Muscle
Target: 1.6-2.2g per kilogram of bodyweight daily
For a 75kg person: 120-165g protein daily For a 90kg person: 144-198g protein daily
This range consistently produces results across different client types, training experience levels, and genetic responses.
Can you build muscle with less? Possibly, but you’re leaving gains on the table. Do you need more? Rarely, unless you’re very lean or have specific circumstances.
For Fat Loss While Maintaining Muscle
Target: 2.0-2.4g per kilogram of bodyweight daily
Higher protein during calorie deficits protects muscle mass whilst satisfying hunger better than carbs or fats.
For a 75kg person cutting: 150-180g daily For a 90kg person cutting: 180-216g daily
The leaner you are, the higher protein needs to be to preserve muscle during deficit.
For General Health and Maintenance
Target: 1.2-1.6g per kilogram of bodyweight daily
If you’re training moderately but not specifically trying to build muscle, lower protein is adequate.
But honestly? Most people underestimate rather than overestimate protein needs. Going slightly higher rarely causes problems.
Why Most People Eat Far Less Than They Think
I’ve tracked nutrition for probably 200+ clients over the years. The pattern is consistent.
Client thinks they eat: “Pretty high protein, maybe 100-120g daily” Client actually eats: 60-80g daily
The gap between perceived and actual protein intake is massive.
The Breakfast Problem
Most people’s breakfast is almost entirely carbs: toast, cereal, pastries, fruit.
Protein content: maybe 10-15g if you’re lucky.
You’ve already put yourself behind for the day. Catching up later is harder than starting properly.
The “Healthy” Salad Trap
“I had a healthy salad for lunch.”
Lettuce, tomatoes, cucumber, some dressing, maybe a bit of chicken.
Protein content: 15-20g if there’s decent chicken. Often less.
You think you’re eating well. You’re not hitting protein targets.
The Snacking Gap
Snacks are usually carb or fat-heavy: crisps, biscuits, fruit, nuts.
Protein content: minimal to none.
These calories count toward daily total but contribute almost nothing to protein target.
What Optimal Protein Distribution Actually Looks Like
Don’t just hit daily total—distribute it properly across meals.
Aim for 30-40g Per Main Meal
Research suggests muscle protein synthesis peaks around 30-40g per meal and doesn’t increase much beyond that.
Eating 100g protein in one massive dinner is less effective than spreading 25-30g across four meals.
Client example: James ate 140g protein daily but consumed 90g at dinner, minimal amounts at other meals.
We redistributed to 30g at breakfast, 35g at lunch, 40g at dinner, 35g post-training. Same total protein, noticeably better progress over the next eight weeks.
The Breakfast Importance Nobody Talks About
You’ve fasted overnight. Your body’s been catabolic for 8+ hours.
First meal sets the tone for protein synthesis for the day.
Starting with a high-protein breakfast (30-40g) is one of the simplest improvements most clients can make.
Post-Training Window (Overrated but Still Useful)
The “anabolic window” isn’t as critical as 2000s fitness magazines claimed. But getting protein within 2-3 hours post-training is still beneficial.
Not magical. Just sensible.
I typically recommend 30-40g protein within two hours of training. Convenient option: protein shake. But whole food works just as well.
The Best Protein Sources (Practical Reality)
Theory says “eat varied whole food protein sources.”
Reality says you need convenient, affordable, palatable options you’ll actually consume consistently.
Tier 1: Complete Proteins (Best)
Chicken breast: 31g protein per 100g, cheap, versatile Turkey mince: 29g protein per 100g, leaner than beef White fish (cod, haddock): 20-24g protein per 100g, very lean Greek yoghurt: 10g protein per 100g, convenient breakfast/snack Eggs: 6g protein per large egg, cheap, quick Lean beef: 26g protein per 100g, provides iron and B vitamins Cottage cheese: 11g protein per 100g, convenient
These should form the bulk of your protein intake.
Tier 2: Good But Less Protein-Dense
Salmon: 20g protein per 100g, provides omega-3s (worth the lower protein density) Tofu: 8g protein per 100g, good plant option Lentils: 9g protein per 100g cooked, provides fibre Quinoa: 4.4g protein per 100g cooked, complete amino acid profile
These are nutritious but you’ll need larger portions to hit protein targets.
Tier 3: Supplements (Convenient, Not Essential)
Whey protein powder: 20-25g protein per 30g scoop, very convenient Casein protein: 24g protein per 30g scoop, slow-digesting (useful before bed) Vegan protein blends: 20-24g per scoop if quality brand
Supplements are tools, not magic. Use them to hit targets conveniently, not as primary protein source.
I use protein powder myself. It’s practical. But whole food should provide the majority.
The Meal Plans That Actually Work
Let me show you what 150g daily protein actually looks like for a typical client.
Example 1: Office Worker (Male, 75kg)
Breakfast (7:30am): 3 scrambled eggs, 2 slices wholemeal toast Protein: 20g
Mid-morning (10:30am): Greek yoghurt with berries Protein: 15g
Lunch (1pm): Chicken breast (150g), quinoa, vegetables Protein: 47g
Post-training snack (6pm): Protein shake Protein: 25g
Dinner (8pm): Salmon fillet (180g), sweet potato, broccoli Protein: 36g
Evening snack (10pm): Cottage cheese Protein: 12g
Daily total: 155g protein
Distributed across six eating occasions. No single meal requires massive protein serving.
Example 2: Busy Parent (Female, 65kg)
Breakfast (6:30am): Protein overnight oats (oats, protein powder, milk) Protein: 30g
Lunch (12:30pm): Tuna salad with chickpeas Protein: 35g
Afternoon snack (3:30pm): Protein bar or handful of nuts with yoghurt Protein: 15g
Dinner (7pm): Turkey mince bolognese (150g turkey), pasta Protein: 44g
Evening (9:30pm): Glass of milk or small protein shake Protein: 10g
Daily total: 134g protein
Hits 2.0g/kg target without requiring elaborate meal prep or expensive ingredients.
Common Protein Mistakes I See Constantly
After tracking nutrition for hundreds of clients, these errors repeat weekly:
Mistake 1: Front-Loading Dinner
Eating minimal protein at breakfast and lunch, then consuming 70-80g at dinner.
Your body can’t effectively utilize that much protein in one sitting for muscle building. You’re wasting some of it.
Spread it across the day for better utilization.
Mistake 2: Relying on “Protein-Rich” Foods That Aren’t
“I ate peanut butter, that’s protein.”
Peanut butter is 25% protein, 50% fat. Per tablespoon: 4g protein, 8g fat.
It’s a fat source that contains some protein. Not a protein source.
Same with nuts, seeds, legumes—they contain protein but need to be consumed in large amounts to hit targets.
Mistake 3: Not Counting Liquid Calories
“I only had a protein shake, that doesn’t count as a meal.”
Yes it does. It’s 120-150 calories and 25g protein.
Track everything that contains calories, including shakes. They contribute to daily totals.
Mistake 4: Vegetarian/Vegan Without a Plan
“I’m vegetarian so I can’t hit protein targets.”
Wrong. It’s harder, requires more planning, but absolutely possible.
You need to intentionally combine: tofu, tempeh, legumes, quinoa, seitan, protein powder, nuts, seeds.
It’s doable. Just requires more attention than eating chicken breast.
Client example: Sophie, vegan, trained consistently, made minimal progress for four months. Tracked nutrition: averaging 65g protein daily at 62kg bodyweight.
We structured meals around tofu, tempeh, protein powder, legumes. Got her to 120g daily. Next three months: visible muscle growth, strength improvements.
The training was fine. The protein wasn’t.
Mistake 5: Thinking More Is Always Better
“If 150g is good, 250g must be better.”
Beyond roughly 2.2-2.4g/kg, additional protein provides minimal benefit for muscle building.
You’re not gaining extra muscle. You’re just eating expensive calories that could be carbs or fats providing more energy for training.
There’s an optimal range. More isn’t always better.
Protein Myths I’m Tired of Hearing
Let me address the nonsense that circulates constantly:
“High Protein Damages Your Kidneys”
No evidence for this in healthy individuals.
If you have pre-existing kidney disease, high protein can be problematic. If you don’t, it’s not an issue.
I’ve eaten 180-200g daily for over a decade. Kidney function tests are perfect.
“You Can Only Absorb 30g Per Meal”
Misunderstanding of research.
Your body can digest and absorb far more than 30g per meal. The question is how effectively it’s utilized for muscle protein synthesis.
Eating 60g in one meal isn’t wasteful—it’s just potentially less efficient than spreading it across two meals.
“Plant Protein Isn’t as Good as Animal Protein”
Plant proteins are often “incomplete” (missing some amino acids) and less bioavailable.
But if you eat varied plant proteins and sufficient quantity, you can absolutely build muscle.
Animal protein is easier and more efficient. Plant protein requires more attention. Both work.
“You Need Protein Immediately Post-Workout”
The “anabolic window” is several hours, not 30 minutes.
Getting protein within 2-3 hours is beneficial. Obsessing about immediate post-workout consumption is unnecessary.
If you train at 6pm and eat dinner at 7:30pm, that’s fine. You don’t need to skull a shake in the changing room.
When Higher Protein Makes Sense
Most people need the standard 1.6-2.2g/kg range. But some situations warrant higher intake:
During Fat Loss
2.0-2.4g/kg helps preserve muscle whilst in calorie deficit.
The leaner you get, the higher protein should be to protect muscle mass.
If You’re Older (40+)
Protein utilization efficiency decreases with age. Slightly higher intake (2.0-2.2g/kg) compensates.
If You’re Very Lean
Once you’re below 12% body fat (men) or 22% (women), protein needs increase to maintain muscle mass.
If You’re Training Very Frequently
High training volume increases protein requirements slightly.
Someone training 5-6 days weekly probably benefits from the higher end of the range.
The Simplest High-Protein Habits
Don’t overcomplicate this. A few habits cover most requirements:
Habit 1: Start every day with 30g protein at breakfast Examples: 3-egg omelette, protein pancakes, Greek yoghurt with protein powder
Habit 2: Plan meals around protein source first Choose the protein (chicken, fish, tofu), then add carbs and vegetables
Habit 3: Keep convenient protein options available Greek yoghurt, hard-boiled eggs, protein bars, jerky—something grabbable when busy
Habit 4: Use protein powder strategically Morning shake if breakfast is rushed, post-training convenience, evening top-up if short on daily total
Habit 5: Track for one week Just once, track everything you eat for seven days. See where you actually stand versus where you think you are.
How to Track Protein Properly
You don’t need to track forever. But tracking for 1-2 weeks shows you reality.
Use MyFitnessPal or similar: Input everything you eat, even rough estimates
Weigh protein sources initially: You’ll quickly learn what 150g chicken looks like, but weigh it a few times first
Count everything: Milk in coffee, protein in grains, everything contributes
Aim for daily target: 1.6-2.2g/kg bodyweight
Adjust based on results: If you’re not making progress after 6-8 weeks despite consistent training, protein might be the issue
Once you’ve tracked for a week or two, you’ll have a feel for what hitting targets requires. Then you can estimate rather than tracking every meal.
What If You Can’t Hit Protein Targets?
Sometimes life gets in the way. Travel, illness, incredibly busy periods.
Here’s the hierarchy of importance:
Priority 1: Get close to target (even 80% is better than 50%) Priority 2: Distribute somewhat evenly (don’t just eat it all at dinner) Priority 3: Time around training (within 2-3 hours)
If you hit 120g when 150g is target, that’s fine occasionally. Consistency over weeks matters more than perfection daily.
But if you’re consistently 30-40% below target, that’s why you’re not building muscle despite training.
The Bottom Line
Protein requirements for building muscle: 1.6-2.2g per kilogram bodyweight daily for most people.
That’s 120-165g for a 75kg person. Distributed across 3-4 meals. Emphasising complete protein sources.
Get this right, and training produces results. Get it wrong, and you’ll wonder why months of consistent gym work haven’t changed your physique.
Most people drastically underestimate how much protein they’re actually eating. Track it properly for one week. You’ll probably be shocked by the gap between perception and reality.
The training advice I give matters. The progressive overload matters. The programme structure matters.
But if protein intake isn’t adequate, none of it produces optimal results.
