What to Eat Before, During and After a Workout ?

Most of us tend to completely forget about nutrition the moment we start enjoying our workouts and the sculpting of our body. By thinking that we deserve to reward ourselves for our hard efforts, we resort to instant gratification in the shape of unwise food choices and empty calories.

But at the end of the day, what kind of fuel you put inside your body is what separates success from failure — and you have the power to make food your best ally instead of your worst enemy. One thing is for sure: no amount of sweat in the gym can erase the damage done by stuffing yourself with unhealthy food all throughout the day.

Different goals require different diets. A sprinter may need to eat differently than a long distance runner, and a bodybuilder may need to eat differently than a powerlifter. But these general principles about pre and post workout nutrition will come in handy regardless of what you’re training for.

No matter whether this is your first time working out or you’re an experienced athlete, eating the right food at the right time will promote better training results. Here’s how to optimise your gains by making smarter food choices before, during, and after your workouts.

What to Eat Before a Workout

Your pre-workout meal is the fuel load for everything that follows. Get it right and you’ll train harder, recover faster, and build more muscle. Get it wrong and you’ll either be running on empty or sluggish from digesting a heavy meal mid-session. Specifically, a good pre-workout meal does two things: it maximises your energy and performance during the workout itself, and it kick-starts recovery before the workout even ends — since digestion takes anywhere from a couple of hours to 7–8 hours depending on the meal, the right building blocks eaten beforehand are often still circulating as you finish your last set.

Timing

The sweet spot for a full meal is 1.5–3 hours before training. This gives you enough time to digest a proper meal without leaving you hungry by the time you start warming up. If you’re training early and can’t eat a full meal beforehand, a smaller snack 30–60 minutes before training is better than nothing — more on that below.

If you want more precision, scale the timing to the size of the meal:

• Full meal (400–600 calories): eat 2–3 hours before training, giving your digestive system enough time to process it before blood flow diverts to your muscles during exercise.
• Medium meal (200–300 calories): eat 1–2 hours before training.
• Small snack (under 200 calories): eat 30–60 minutes before training.

The bigger the meal, the more lead time it needs — the more blood your stomach needs to digest, the less is available for your working muscles.

What to Eat

The pre-workout meal should centre on two things: carbohydrates and lean protein.

For a full meal eaten with real lead time (1.5–3 hours out), lean toward slow-digesting carbohydrates. Slow-digesting, complex carbs provide a sustained energy release throughout your session rather than a quick spike and crash — think of them as the slow-burn logs on your training fire. If you’re eating closer to training, or you specifically want fast fuel availability going into a high-intensity session, lean toward faster-digesting carbs instead — white rice, potatoes, low-fiber fruit, juice, or dextrose — since there isn’t enough time left to fully digest something slower.

Protein eaten before training raises blood amino acid levels during the session itself, which means more building material available for your muscles while you’re actually working them — helping keep you in an anabolic state rather than slipping into a catabolic one. Research has shown that pre-workout protein can increase muscle protein synthesis both during and after training. Aim for roughly 25–35 grams — more than that is unnecessary and harder to digest quickly before you train. Favor fast-digesting sources here: whey protein is the ideal pre-workout choice, since it absorbs quickly, sits light on the stomach, and spikes blood amino acids faster than whole food proteins.

Best pre-workout carb sources: oats, whole grain bread, brown rice, sweet potatoes, yams, brown pasta, fruit (bananas are particularly good — they provide fast-acting carbs and potassium which prevents muscle cramping), or for a quicker-fuel option closer to training: white rice, potatoes, juice, or dextrose.

Best pre-workout protein sources: boiled eggs, chicken breast, Greek yogurt, cottage cheese, whey protein powder, tuna, egg whites. Avoid casein and other slow-digesting proteins pre-workout — save those for before bed.

A reliable pre-workout combination: oatmeal with whey protein and a piece of fruit. The fibre in oatmeal slows the absorption of the fruit sugars, giving you a steadier energy release. The whey provides fast-absorbing amino acids. Simple, cheap, and it works.

Other solid options: whole grain bread with peanut butter (without added sugar), chicken with brown rice, eggs with toast, Greek yogurt with banana and a handful of almonds.

What to Avoid Before a Workout

Fat. Fat is not your friend pre-workout. It slows digestion significantly, which means slower nutrient delivery to your muscles and a greater chance of feeling heavy, sluggish, or nauseated during training. Save the avocado, nuts, and olive oil for other meals — before training, keep fat to an absolute minimum.

Fiber. Fiber is a very important nutrient for health and protein absorption, but not immediately before training. Like fat, fiber slows digestion, keeps food in your stomach longer, and can cause discomfort during intense exercise. High-fiber foods — beans, bran, whole grain breads with lots of seeds — are better saved for meals further from your session.

Large, heavy meals close to training. During training, blood flow diverts away from your stomach to the working muscles, particularly during large compound movements like squats and deadlifts that involve big muscle groups. This interrupts digestion and can cause discomfort, cramping, and nausea. The bigger your pre-workout meal, the more time you need to let it digest — and anything sugary on its own is worth avoiding too, since it gives you a spike and crash before the session ends.

Pre-Workout Snacks (30–60 Minutes Before)

If you don’t have time for a full meal, a light snack 30–60 minutes before training is your next best option. Keep it small, easy to digest, and carb-focused with a little protein:

• A banana with a tablespoon of peanut butter
• A handful of dates or raisins with a small handful of almonds or walnuts
• A rice cake with cottage cheese
• A small whey protein shake with a piece of fruit
• Greek yogurt with a drizzle of honey
• A small bowl of oats with honey

Avoid heavy foods, high-fat items, and anything that will still be sitting in your stomach when you’re halfway through your first working set. Related: Power Up: The Best Pre-Workout Snacks

Training Fasted? Consider BCAAs

Some people prefer the feeling of an empty stomach when they work out. If that’s you, consuming 15–20 grams of BCAAs before training ensures your muscles still have the amino acids they need to stay anabolic during the session — without the digestive load of a full meal. This is particularly useful for morning fasted training.

Hydration Before Training

Start your workout already hydrated. Aim to drink 400–600ml of water in the 2 hours before training. Even mild dehydration — as little as 2% of body weight — measurably impairs strength, endurance, and focus. Don’t wait until you’re thirsty; by then you’re already behind.

Advanced: Supplements That Enhance Pre-Workout Nutrition

Probiotics. Probiotics contain bifidus and acidophilus bacteria strains that support gut health. Studies have shown that a healthy colony of gut bacteria leads to increased digestive system functionality, better immune system function, and greater resistance to food allergies and intolerances. Taking a probiotic with your pre-workout meal can speed up digestion and reduce the risk of an upset stomach during training — particularly useful if you find heavy meals before exercise uncomfortable.

Insulin sensitivity supplements. Insulin sensitivity determines how efficiently your body stores glycogen in muscle cells versus fat cells. The more insulin sensitive you are, the less insulin is needed to store the same amount of glycogen as muscle fuel — and the less ends up stored as fat. Several supplements can improve insulin sensitivity when taken with your pre-workout meal:

• Resveratrol — acts directly on cells to improve insulin signalling
• L-Carnitine — supports fatty acid metabolism and insulin sensitivity
• Alpha Lipoic Acid (ALA) — a powerful antioxidant that enhances glucose uptake into muscle cells

Sample Pre-Workout Meals

2–3 hours before training (full meal):

• Chicken breast with white rice and a side of fruit
• Egg whites with white rice or potatoes and a glass of juice
• Whey protein shake with a banana and a small portion of white rice
• Greek yogurt (low-fat, plain) with a banana and a drizzle of honey

30–60 minutes before training (light snack):

• Whey protein shake with a banana or a piece of fruit
• Rice cakes with a thin spread of peanut butter
• A small bowl of oats with honey
• 15–20g of BCAAs if training fully fasted

What to Eat During a Workout

For most gym sessions lasting under an hour, you don’t need to eat anything during training. Water is enough. But for longer or particularly intense sessions — two hours or more — in-session nutrition can make a meaningful difference to your performance in the second half.

Hydration — The Non-Negotiable

Good hydration is the most important during-workout nutrition factor for the vast majority of training sessions. In between sets, take frequent sips of water. Aim for 200–300ml (7–10 ounces) every 10–20 minutes throughout your session.

During training, you’re losing significant amounts of water through sweat — and with it, electrolytes like sodium, potassium, and magnesium that support muscle contraction. If your sessions are particularly long or you sweat heavily, a sports drink or electrolyte tablet in your water bottle is worth considering. But for a standard 45–60 minute weights session, water alone is fine.

Fuel for Longer Sessions

If your workouts are especially strenuous and long — think endurance training, two-a-days, or extended circuit sessions — aim to consume around 50 extra fast-acting calories every 30 minutes to maintain energy levels. The goal is to keep blood glucose stable and prevent the energy crash that hits when glycogen stores run low.

Best options for during training: bananas, raisins, energy gels, sports drinks (in longer sessions), dates, rice cakes. Keep it simple and easy to eat quickly — you’re not sitting down to a meal, you’re refuelling on the move.

BCAAs are also worth considering for long sessions. Sipping on a BCAA drink throughout training reduces muscle protein breakdown, prevents mental fatigue by competing with tryptophan for brain entry, and keeps energy levels more stable. Related: BCAAs: The Complete Guide

What to Eat After a Workout

The post-workout meal might be the most important meal of your day. Immediately after training, your muscles are depleted of the glycogen that fuelled their contractions during the session, muscle tissue is damaged and needs repair, and your body is in a catabolic state — breaking down protein for energy rather than building it into muscle.

Your job post-workout is to reverse all three of these things as quickly as possible.

The Post-Workout Window

For the first 30–45 minutes after training, your muscles are in a uniquely receptive state — insulin sensitivity is elevated, blood flow to muscles remains high, and the body is primed to absorb and use nutrients. Use this period of time to refuel your muscles and provide the building blocks for growth.

What you need in this window: fast-digesting protein to start muscle repair, and fast-digesting carbohydrates to restore glycogen and spike insulin — which drives amino acids and glucose into the muscle cells.

Immediate post-workout (within 30–45 minutes):

• Whey protein isolate — the fastest-absorbing protein available, ideal for this window
• High-glycemic carbs — white rice, white bread, potatoes, even something sweet. This is the one time of day when fast-digesting carbs are not just acceptable but preferable
• A classic post-workout shake: whey protein + banana + water or milk

Don’t overthink it. A whey protein shake with a fast carb source — banana, rice cakes, a glass of juice — covers everything you need in the immediate window. Related: Proper Post-Workout Nutrition: What to Eat After Training

The Full Post-Workout Meal (2–3 Hours After Training)

After the immediate window, it’s time for a proper balanced meal. This is where you consolidate the recovery process and provide the sustained protein and nutrient supply your muscles need for the next several hours.

A well-structured post-workout meal includes:

• Quality protein: lean meat (chicken, turkey, lean beef), fish (salmon, tuna, cod), eggs, or cottage cheese. Aim for 30–50 grams of protein in this meal.
• Complex carbohydrates: brown rice, sweet potato, whole wheat pasta, oats, or quinoa. Back to slow-digesting carbs now — the fast-carb window has passed.
• Vegetables: broccoli, spinach, kale, mixed greens — for micronutrients, fiber, and anti-inflammatory compounds that support recovery.
• Healthy fats: avocado, olive oil, or the fat from your fish or eggs. Fats support hormone production and reduce inflammation.

Sample post-workout meals: grilled chicken with brown rice and broccoli; salmon fillet with sweet potato and spinach; beef stir-fry with mixed vegetables over brown rice; omelette with vegetables and whole grain toast.

Before Bed — Don’t Forget the Final Meal

One often-overlooked part of workout nutrition is the pre-sleep meal. Your body does its most intensive repair and growth work during sleep — but it needs raw materials to do it. Going to bed without adequate protein means your muscles go 7–9 hours in a fasted, potentially catabolic state.

A slow-digesting protein source 30–45 minutes before sleep keeps amino acids available throughout the night. Casein protein is the gold standard here — it forms a gel in the stomach and releases amino acids steadily over 5–7 hours. Cottage cheese and Greek yogurt are excellent whole-food alternatives, both naturally high in casein. Related: Casein Protein: Benefits, When to Take It, and Why You Need It Alongside Whey
