Is it worth training on an empty stomach?

Light morning exercise before breakfast can work for some people, but in more intense training an empty stomach shows in your performance. If your muscles' glycogen stores are low, fatigue hits sooner and recovery is slower. If eating in the morning feels difficult, even a small snack can help with fuelling.

Pre-Workout Snack – What to Eat Before Training and When?

Q: What should I eat before the gym?

The best pre-gym snack contains easily digestible carbohydrates and a moderate amount of protein. A protein cookie and a banana, for example, make a great combination: the carbs give you energy for the session and the protein supports your muscles. Eat a bigger snack 1–2 hours before training, or a small one 30 minutes before.

Q: What should I eat before a run?

Before a run, a light and easily digestible snack is especially important. Your body is in constant motion during a run, so a heavy stomach hurts performance and can cause cramps. Carbohydrates take priority before a run, depending on its length and intensity. For longer runs, start fuelling well in advance.

Mitä syödä ennen treeniä: helposti sulava urheilijan välipala, kuten proteiinikeksi tai smoothie, antaa energiaa ja tukee lihaksia ennen liikuntasuoritusta.

Why do we — the people who actually make protein cookies — eat one before every workout? Well, anyone who's ever dragged themselves to the gym on an empty stomach knows the answer: the right pre-workout snack can make a surprising difference to how your session feels and the results you get from it.

Get the timing and the ingredients right, and a snack gives you energy, lifts your performance, and supports your muscles without weighing you down. And finding a well-rounded snack to back up your training is easier than you'd think — especially now that you've landed on our blog!

What to eat before a workout – carbs and protein

Before exercise, carbohydrates are your body's number one fuel. Carbs top up your muscles' glycogen stores, which boosts performance and keeps fatigue at bay mid-session. It's worth adding a moderate amount of protein too — that way it supports your muscles during the workout itself, not just in recovery.

The best pre-workout snack is easy on the stomach: too much fat or fiber slows digestion and can leave your gut grumbling right when you need it least. Good options include a banana, a protein cookie, or a smoothie.

Why your pre-workout snack matters

Training fasted can sound tempting — especially if fat loss is the goal — but the longer and harder the session ahead, the more fueling up beforehand pays off. You'll get the best results by leading with carbs and adding a moderate dose of protein. A pre-workout snack helps your muscles work harder, delays fatigue, and keeps your focus sharp through the whole session — especially when your last proper meal is a distant memory.

Hydration counts for performance too, so drink enough water before you train! Even mild dehydration drags down your energy levels and your metabolism.

A good rule of thumb: eat 1–2 meals or snacks containing carbs and protein in the four hours before exercise. The closer you get to your workout, the lighter the snack should be.

The best time to eat before a workout

When to eat before training depends on how big the meal is and what's in it. Give a larger meal 2–3 hours to digest properly before you train. A light snack works 30–60 minutes out, as long as it delivers quick energy without any digestive drama. A banana or a protein cookie, for example, is a brilliant choice.

The best pre-workout snacks – easy options for everyday life

Eat what your body handles well — everyone's stomach has its own opinions about what works. Test a few options and find your favorite:

Protein cookie – the practical, no-fuss snack for athletes and active people. Energy + protein + minerals in one package that slips straight into your gym bag.
Banana – a classic for a reason. A great source of carbs and potassium, easy to digest, and instant fuel. Even better paired with a protein cookie.
Oatmeal with berries – steady, slow-release energy, perfect for longer sessions. Eat it 1–2 hours before training.
Smoothie – quick and easy to digest. Blend in some protein powder and your snack is sorted.
Yogurt and granola – a solid source of protein and carbs that really shines 1–2 hours before training.

Pre-workout snack options: a protein cookie, oatmeal with berries, a smoothie, or a banana. A protein cookie delivers the carbs and protein your training needs.

Why a protein cookie makes a great pre-workout snack

Protein cookies solve a very familiar everyday dilemma: what to eat before the gym when you're already running late. A great-tasting protein cookie gives you fast-absorbing carbs for energy, enough protein to keep your muscles going, and important minerals like magnesium, iron, and zinc on top. And they travel well — drop one in your bag in the morning and eat it on the way to training.

Planet Amino protein cookie – the athlete's snack before and after training

Planet Amino protein cookies pack 15–20 grams of protein and plenty of fiber, which makes them a genuinely filling snack before and after training. They also deliver the energy your body needs while you exercise.

Planet Amino protein cookies contain all the essential amino acids, too. What sets them apart from other protein cookies and high-protein snacks? A plant-based recipe and a taste you'll actually look forward to — and they work just as well as pre-workout fuel as they do for post-workout recovery.

What to eat after a workout – recovery done right

Recovery starts the moment you finish your last rep. Within an hour of exercise, your body wants nutrients so it can repair the damage training caused and bounce back properly. This is where protein and carbs come in: protein rebuilds your muscles, and carbs refill their glycogen stores.

The bottom line – the best pre-workout snack

Carbs plus protein: a winning combination both before and after training. A snack earns its place whenever your last meal was hours ago or a hard session is coming up.

When your pre-workout eating is dialed in, you've got more in the tank and training simply feels better. And afterward, the nutrients you take in drive recovery and help you keep improving.

Frequently asked questions about eating and training

What should I eat before the gym?

The best pre-gym snack combines easily digestible carbs with a moderate amount of protein. A protein cookie and a banana, for example, make a winning duo: the carbs power your session and the protein backs up your muscles. Have a bigger snack 1–2 hours before training, or a small one 30 minutes out.

What should I eat before a run?

Before a run, keeping it light and easy to digest matters more than ever. Your whole body is in motion with every stride, so a heavy stomach hurts your performance and can bring on cramps. Carbs take center stage before a run — how many depends on its length and intensity. For longer runs, start fueling well in advance.

Should I train on an empty stomach?

A light morning session before breakfast works for some people, but crank up the intensity and an empty stomach will show in your performance. When your muscles' glycogen stores run low, fatigue hits sooner and recovery takes longer. If eating in the morning feels like a chore, even a small snack helps with fueling. Experiment and see what works best for you.
