Aim for 0.8g of protein per pound of bodyweight — so if you're 90kg, that's around 160g a day.
Most tradies aren't hitting that. The reasons are practical: you're up at 5am, you're on a site by 7, you don't have time to cook a chicken breast for breakfast.
This is where shakes come in. Fast, portable, calorie-efficient, and high-protein. And before you say "I don't have a blender on site" — you don't need one. All of these work with a shaker bottle. A 600ml shaker costs about £5 and fits in your work bag.
Here are 5 that actually taste decent and hit 30–60g of protein each.
What You Need First: A Good Protein Powder
Everything below uses a standard whey protein isolate or concentrate. Unflavoured or vanilla works best for versatility. If you're lactose intolerant, go for a whey isolate (lower lactose) or a plant-based blend.
A rough guide: one 30g scoop of whey = around 23–25g protein. Two scoops = 46–50g.

Recipe 1: The Site Starter
Recommended for you
Tradie Shopping List Bundle
Done-for-you weekly shopping lists — high protein, site-friendly
When to use it: First thing in the morning, before leaving for work.
What you need:
- 2 scoops vanilla whey (46g protein)
- 300ml full-fat milk (11g protein)
- 1 banana (sliced, pre-frozen works best but not essential)
How to make it: Add powder to shaker, pour milk in, shake for 20 seconds. Peel and eat the banana on the way out the door separately, or mash it in with a fork before shaking if you've got 30 seconds.
Macros (approx): 57g protein | 65g carbs | 8g fat | ~570 kcal
This is a proper breakfast — calorie-dense, protein-packed, and genuinely filling. No excuses for skipping breakfast on an early start.
Recipe 2: The Peanut Butter Gainer
When to use it: Post-work or before bed if you need extra calories.
What you need:
- 2 scoops chocolate whey (46g protein)
- 300ml whole milk
- 2 heaped tablespoons peanut butter
- Pinch of salt (sounds odd, tastes great)
How to make it: This one needs a bit of work to get the peanut butter to mix — put the peanut butter in first, pour a small amount of warm water over it, stir until loose, then add the powder and milk and shake hard.
Macros (approx): 62g protein | 30g carbs | 32g fat | ~660 kcal
Trades work burns a lot of calories. If you're struggling to maintain weight while building muscle, this shake is your best mate.
Recipe 3: The Oat and Berry Rebuild
When to use it: Post-gym or after a long physical day when your muscles need glycogen replenishment.
What you need:
- 2 scoops strawberry or vanilla whey
- 300ml water or milk
- 4 tablespoons instant oats (the kind that dissolve — not rolled oats)
- 1 small handful frozen berries (pre-portioned the night before in a sandwich bag)
How to make it: The trick is using instant oats, not regular — they dissolve in liquid without clumping. Add everything to the shaker, shake for 30 seconds. The berries will be slushy which is actually fine — adds texture.
Macros (approx): 53g protein | 50g carbs | 5g fat | ~470 kcal
The oats provide slow-release carbs to refuel glycogen stores. Ideal for post-gym when you're heading back to work and can't eat a proper meal.
Recipe 4: The Quick-Hit Coffee Shake
When to use it: Mid-morning when you need a protein hit and an energy boost.
What you need:
- 2 scoops vanilla or unflavoured whey
- 250ml cold black coffee (make it the night before and stick it in the fridge, or use a can of cold brew)
- 150ml milk
- Optional: 1 teaspoon honey
How to make it: Combine in shaker and shake. Done in 20 seconds.
Macros (approx): 50g protein | 15g carbs | 4g fat | ~295 kcal
Low calorie, high protein, caffeine hit built in. Perfect if you had a big breakfast and just need a protein top-up without a full meal. The coffee flavour works really well with vanilla whey.
Recipe 5: The Emergency Kit Bag Shake
When to use it: When you've got nothing else and you need something fast.
What you need:
- 2 scoops any flavour whey
- 300ml water
- 1 packet of instant oats (the single-serve sachets — keep a box in the van)
How to make it: Add water and shake. Eat the dry oats separately if needed (they're edible dry, they're just not exciting) or stir them in with a bit of water and eat with a spoon.
Macros (approx): 50g protein | 35g carbs | 4g fat | ~380 kcal
This is your fallback. Keep 5–6 single-serve oat sachets and a bag of protein in the van at all times. There is no excuse for missing your protein target when you've got this set up.
Tips for Staying on Top of Protein on Site
Pre-portion everything the night before. Put your powder in the shaker (lid on), put your extras in a sandwich bag, stick it all in the fridge. Takes 2 minutes and means you're not fumbling around at 5:30am.
Set a target, not a vague goal. If you know you need 160g of protein, track it for one week. You'll quickly see where the gaps are.
Milk beats water for protein shakes. 300ml whole milk adds 11g of protein before the powder. Use it when you can.
Greek yoghurt is another easy win. 200g of full-fat Greek yoghurt = 20g protein. Dead easy snack to keep in a cool bag on site.
