What To Eat Before & After Training

You do not need a supplement stack and a stopwatch. But what you eat around a session genuinely affects how hard you can train and how well you recover, and most women get it wrong in the same two ways: too little before, and too long a gap after.

Here's what to eat, when, and the reasoning behind it, so you can make your own decisions rather than following a rule you don't understand.

01The simple version

That's genuinely most of it. The rest of this guide is the why, and the how when life isn't tidy.

02Before training: what and why

Your muscles run on glycogen, which is carbohydrate stored in the muscle. Lifting hard drains it. Train with it low and everything feels heavier, your last sets disappear, and the session that was meant to build you does less than it should.

Carbs are the priority pre-workout, not protein. Aim for a meal 1 to 2 hours before with a decent carb source and 20 to 30g of protein alongside it.

Keep fat and fibre lower than usual here. Both slow digestion, which is great at other times and unhelpful when you're about to squat. This is the one moment in the day where a lower-fibre choice makes sense.

How much, and how far out

What about caffeine?

Caffeine genuinely works. Around 3mg per kilo of bodyweight, 30 to 60 minutes before training, measurably improves strength, endurance and how hard a session feels. For most women that's a strong coffee or a standard pre-workout scoop. Two caveats: it has a half-life of around five hours, so an evening session plus a pre-workout is why you're staring at the ceiling at midnight, and tolerance builds fast if you use it every day. Save it for your heavy sessions.

03Training in 30 minutes or less

Short notice means you want something that digests fast and won't sit in your stomach: mostly simple carbs, minimal fat, minimal fibre.

04Training first thing: fasted or not?

Fasted training doesn't burn more fat over the day. Total calories decide that, not the timing of your porridge. What fasted training does do is make hard sessions feel harder for most people.

My honest position: if you train at 6am and eating makes you feel sick, train fasted and get a proper meal in straight after. But if you can manage something small, you'll train better. Half a banana, a few rice cakes, or a scoop of whey in water is often enough to change the whole session.

If you do train fasted

Training at different times of day

05After training: what and why

Two jobs after a session: give your body the protein to rebuild the tissue you just broke down, and replace some of the glycogen you burned.

The "anabolic window" was oversold for years. You do not have 30 minutes before your session is wasted. What's actually true: getting 20 to 40g of quality protein within a couple of hours is a sensible target, and if you trained fasted, sooner is better.

Carbs after training aren't the enemy. They're the thing that refills your muscles so the next session isn't worse than this one. Women who cut carbs entirely tend to feel flat, train poorly and lose the shape they wanted in the first place.

How much protein, actually

Research points to roughly 0.4g per kilo of bodyweight per meal as a solid dose for muscle building, which is 25 to 35g for most women. More in one sitting isn't wasted, but it isn't better either. What matters far more is that you get three or four doses like that spread across your day, rather than 15g at breakfast and 70g at dinner.

Does the "anabolic window" exist at all?

Sort of, but it's a barn door rather than a keyhole. Muscle stays sensitive to protein for well over 24 hours after training. The one time it genuinely matters is if you trained fasted or it's been five or six hours since you last ate protein. Otherwise, eat your next normal meal and stop setting alarms.

Do you need to refuel immediately?

Only if you're training twice in a day or doing something long and brutal. If your next session is 24 hours away, your muscles will refill from your normal meals long before then. This is where a lot of supplement marketing preys on people.

06Protein shakes: useful, not magic

A shake is a convenient way to hit a protein target when whole food isn't practical. It has no special powers over chicken or eggs. Use it when the convenience genuinely helps — straight after a session, on a busy workday, or when you're 30g short at 9pm.

Food, soreness and recovery

Being sore for two days isn't a sign of a good session, and no meal eliminates it. But a few things genuinely help you recover between sessions.

07Water, and the thing everyone ignores

Being even slightly dehydrated hurts strength and makes recovery worse. Aim for around two litres a day as a base, more if it's hot or you sweat heavily, and sip through your session rather than drinking a pint at the end. If you take creatine, add extra on top.

08Around the session vs across the day

Here's the honest hierarchy, because it's easy to obsess over the small stuff and miss the big stuff.

Meal timing is on the list, and it's real, but it's fifth. Getting your pre-workout meal perfect while eating 70g of protein a day is polishing the door handles on a house with no roof.

A worked example day

Here's how it looks for a 65kg woman training at 6pm, aiming for around 1,800 calories and 130g protein.

Nothing exotic, nothing timed to the minute, protein in every meal and carbs positioned where they fuel the session. That's the whole thing.
