Protein Timing: Does It Matter When You Eat It?

You’ve probably heard you must drink a protein shake within 30 minutes of training or “lose your gains”. The real picture is calmer — and more practical.

Total intake comes first

The ISSN’s position stand on nutrient timing is clear that total daily protein intake is the most important factor (Kerksick et al., 2017). Timing is a fine-tuning tool, not a make-or-break rule. If you’re consistently short on your daily total, no timing strategy will make up for it.

The “anabolic window” is wider than you think

Post-workout protein can be beneficial, but the window isn’t 30 minutes. Practical guidance from the ISSN is that eating a protein-containing meal within roughly two hours either side of training is a sensible approach (Kerksick et al., 2017). If you ate a good meal a couple of hours before training, there’s no need to rush afterwards.

Your situation	What to do
Ate a protein-rich meal 1–2 h before training	Eat your next normal meal when convenient
Trained fasted (e.g., early morning)	Have protein reasonably soon after
Long gap since your last meal	Don’t leave it too long after training

Spreading protein across the day

An often-cited 2013 study gave trained men 80 g of whey protein over 12 hours after a workout, in three different patterns (Areta et al., 2013):

80 gwhey protein over 12 hours

3patterns compared

4 × 20 gevery 3 h gave the highest response

Areta et al., 2013

Pattern	Muscle protein synthesis
8 × 10 g every 1.5 h	Lowest
2 × 40 g every 6 h	Middle
4 × 20 g every 3 h	Highest

Moderate, evenly spaced servings produced the greatest response. This was a short, lab-based study measuring a marker of muscle building rather than long-term growth, but it supports a simple habit: eat a decent protein portion at each meal.

How much per meal?

The ISSN suggests roughly 0.25 g of protein per kg of bodyweight per meal, or an absolute 20–40 g, spread every 3–4 hours (Jäger et al., 2017).

Bodyweight	Per meal (0.25 g/kg)
60 kg	15 g → round up to ~20 g
75 kg	~19–20 g
90 kg	~23 g

Most people will be well served by 25–40 g per meal across 3–4 meals.

The breakfast gap

Many people eat most of their protein at dinner and very little at breakfast — toast, cereal or just coffee. Fixing breakfast is often the single easiest change:

Typical breakfast	Protein	Upgrade	Protein
Toast with jam	~6 g	Toast with 2–3 scrambled eggs	~20 g
Cereal with milk	~8 g	Greek yoghurt, oats and berries	~25 g
Coffee only	~1 g	Latte + a skyr pot	~22 g

What about before bed?

The ISSN position stand also notes that 30–40 g of casein-rich protein before sleep (such as Greek yoghurt or cottage cheese) may support overnight muscle protein synthesis (Kerksick et al., 2017). It’s a nice option if it fits your routine — not a requirement.

A sample day (~140 g)

Time	Meal	Protein
7:30	Greek yoghurt, oats, berries	30 g
12:30	Chicken and grain bowl	40 g
16:00	Cottage cheese with fruit	22 g
19:30	Salmon, potatoes, greens	35 g
21:30	Glass of milk	8 g

Do protein shakes help?

A shake is simply a convenient protein portion. It’s useful after training when you won’t eat a meal for a while, or to fix a low-protein breakfast. It’s not more effective than food.

Around your training

When you train	Practical approach
Early morning, before breakfast	Have a protein-rich breakfast soon after
Late morning	Normal breakfast, then lunch after training
Lunchtime	Protein-rich snack mid-morning, lunch after
Evening	Normal dinner after training

Protein portions that hit 20–40 g

Food	Portion	Protein (approx.)
Greek yoghurt or skyr	250 g	25 g
Chicken breast, cooked	120 g	37 g
Eggs	3 large	19 g
Tinned tuna	1 tin (drained)	25 g
Firm tofu	200 g	30 g
Cottage cheese	200 g	22 g

Plant-based eaters

Plant proteins often contain less leucine, and some are less digestible. The ISSN position stand on protein suggests that slightly larger servings and a variety of plant sources help (Jäger et al., 2017). Aim for the upper end of the per-meal range. See our plant protein guide.

FAQ

Does eating protein at night make you gain fat? Total daily calories matter for fat gain, not the time of day you eat protein.

I do intermittent fasting. Is that a problem? You can still hit your daily total. Try to fit at least 2–3 good protein portions into your eating window.

The bottom line

Hit your daily total first.
Spread protein over 3–4 meals of 20–40 g each.
Eat a protein-containing meal within a couple of hours of training.
A protein-rich bedtime snack is optional.
