How Much Protein Do Tradies Actually Need? (The Real Numbers)

“Eat more protein.” Everyone says it. Nobody tells you the number.

If you're a tradie doing physical work all day, the answer matters more than most. You're not sitting at a desk. You're carrying, lifting, crouching, climbing, and putting real demand on your muscles from 6am until knock-off. Your protein requirement is genuinely different from an office worker's — and it's also different from a bodybuilder's in ways that surprise most people.

Here's the actual number, what it looks like in practice, and how to hit it without spending a fortune.

Why Protein Targets for Tradies Are Different

The standard NHS guideline for protein is 0.75g per kg of bodyweight. That's the minimum to avoid deficiency — not the number for someone doing physical work.

Office workers doing no exercise can probably get away with around 1.2-1.4g per kg. They're not under sustained physical load. Their muscles aren't being broken down and rebuilt through manual labour.

Tradies are different for a specific reason: you're doing unstructured physical work, not controlled exercise. Carrying materials, repetitive tool use, awkward positions, sustained effort over 8-10 hours — this creates muscle damage and metabolic stress that requires protein to repair. You're also more likely to have joint and connective tissue stress that benefits from adequate protein intake.

Bodybuilders sit closer to 2.2g per kg and above. They're maximising muscle hypertrophy with structured training and often high volume. For most tradies, that's overkill unless you're also training hard in the gym.

The sweet spot for a tradie — especially one doing some gym work — is 1.6-2.2g per kg of bodyweight. Call it 1.8g as your working target.

The Real Number: What Does It Look Like?

Let's put it in plain numbers.

70kg tradie: 112-154g protein per day (target: ~130g)
80kg tradie: 128-176g protein per day (target: ~145g)
90kg tradie: 144-198g protein per day (target: ~165g)
100kg tradie: 160-220g protein per day (target: ~185g)

Take your bodyweight in kilograms, multiply by 1.8. That's your daily target. It sounds like a lot — and compared to what most tradies actually eat, it probably is. Most men eating a typical diet get somewhere around 80-100g without thinking about it. You need to close that gap deliberately.

Breaking It Down Per Meal: What 40-50g Looks Like

The trick is not to think about your daily total — think about hitting a target at each meal. Three meals at 40-50g gets an 80kg tradie to 120-150g with no effort. Add a snack with 20g and you're sorted.

Breakfast — 40-50g protein examples:
4 scrambled eggs (24g) + 200g Greek yoghurt (20g) = 44g
3 eggs (18g) + 2 rashers bacon (10g) + 1 tin of beans (10g) = 38g
150g cooked oats + 2 scoops whey (50g) — quick option when you're out the door at 5:30am

Lunch — 40-50g protein examples:
200g chicken breast (46g) + handful of rice or wrap = 46g
2 tins of tuna (30g) + 4 boiled eggs (24g) = 54g
200g mince in a roll (40g) — the classic

Dinner — 40-50g protein examples:
250g beef mince bolognese (52g)
200g salmon fillet (40g) + eggs on the side
300g chicken thighs (56g)

It doesn't need to be complicated. Eggs, mince, chicken, tuna — rotate those four and you'll hit your number without needing to think too hard.

The Biggest Mistake Tradies Make

Skimping at breakfast and lunch, then trying to catch up at dinner.

It's understandable. You're rushing out the door in the morning. On site, lunch is whatever you can grab — often a roll, a pie, or something from a servo or van. Then you get home, you're starving, and you demolish a massive dinner.

Here's why that doesn't work: your body can only process and use a certain amount of protein at once for muscle repair — roughly 40-50g per meal, though recent research suggests this ceiling is higher than we thought. More importantly, protein synthesis is stimulated by protein, so you want that stimulation multiple times throughout the day, not all at once.

If you eat 20g at breakfast, 20g at lunch, and 120g at dinner — you haven't hit your daily target effectively. The 120g dinner floods your system. Some gets used. A lot gets converted to energy or excreted. The morning and afternoon window — when you actually needed protein to fuel and repair muscle under load — was under-served.

Front-load your protein. Eat the big hit at breakfast. Eat a proper lunch. Let dinner be your smallest meal if needed.

What Happens When You Under-Eat Protein on the Tools

This isn't theoretical.

You lose muscle. If you're not eating enough protein, your body breaks down existing muscle to meet its needs. Manual labour doesn't protect you from this — it actually accelerates it if your intake is low, because your body is in higher-demand state.

Fatigue compounds. Protein isn't just structural — amino acids are involved in neurotransmitter production, immune function, and energy regulation. Chronic low protein intake blunts energy levels in ways that feel like general tiredness but don't respond to sleep.

Injuries linger. Connective tissue — tendons, ligaments, cartilage — repairs slowly and requires protein. If you've had a shoulder niggle or a knee issue that won't clear up, inadequate protein is worth examining. Tradies accumulate repetitive strain injuries that never fully heal, and poor nutrition is a significant factor.

You eat more junk. Protein is the most satiating macronutrient. Low-protein diets leave you persistently hungry, which drives snacking, sugar seeking, and overeating calorie-dense, nutrient-poor food. This is a well-documented mechanism — not willpower.

Hitting Your Target on £8/Day: The Cheapest Protein Sources

The good news: high-protein eating doesn't require expensive food.

Eggs — about £0.25/egg, 6g protein each. A 6-egg breakfast costs £1.50 and delivers 36g protein. One of the cheapest grams of protein you can get, and the most bioavailable.

Beef mince (20% fat) — roughly £3.50-4.50/500g. 500g delivers around 95g protein. That's under 5p per gram of protein.

Canned tuna — £1/tin, 20-25g protein. Hard to beat for convenience. Keep a pack in your work bag.

Chicken thighs (bone-in) — far cheaper than breast, similar protein content, much better flavour. Buy in bulk. £2-3/kg at most supermarkets.

Greek yoghurt (full fat) — £1-1.50 per 500g pot, 10g protein per 100g. Doubles as breakfast or a snack.

Whey protein — often the cheapest gram-for-gram option for hitting your target. 25g protein per scoop, £20-25 for 2kg (that's 80 scoops). Use as backup, not as your primary source.

A realistic £8/day high-protein plan: 6 eggs at breakfast (£1.50), 2 tins tuna for lunch (£2), 500g mince for dinner (£4), Greek yoghurt snack (£0.50). That hits around 170g protein for under £8. Done.

Bottom Line

Stop guessing. Take your bodyweight in kg, multiply by 1.8, and eat that many grams of protein every day.

Spread it across three meals — 40-50g each. Don't skip breakfast. Don't rely on dinner to do all the work.

Eggs, mince, tuna, chicken thighs, Greek yoghurt, and whey are your arsenal. You don't need supplements. You don't need expensive food. You need to be deliberate about it.
