Nutrition for footballers: feeding guide by position and season phase
A professional footballer burns between 1,500 and 2,000 calories during a match — and that's just the competition. Add up the daily workouts, recovery, and accumulated wear and tear of a 9-10 month season, and you have a body that needs to be fed accurately. Not like "a sportsman" in general.
Nutrition is not a complement to training — it is part of training. A player who eats badly yields worse, recovers slower, gets injured more, and loses muscle mass when he should be winning it. And yet, it is one of the most neglected areas in amateur and semi-professional football.
This article gives you a practical framework to feed you as a professional, adapted to the phases of the season and to the days of training, party and rest.

The 3 macronutrients of the footballer
| Macronutrient | Recommended daily amount | Main function | Main sources |
|---|---|---|---|
| Carbohydrates | 4-8 g/kg body weight | Energy for intermittent high intensity forces. Muscle glycogen reserve. | Rice, pasta, oatmeal, potato, sweet potato, fruits, legumes, whole-grain bread |
| Proteins | 1,6-2.0 g/kg body weight | Muscle repair and construction. Post-training and post-partisan recovery. | Chicken, fish, eggs, lean meat, dairy, legumes, tofu |
| Fats | 20-35 % of total calories | Long-lasting energy, vitamin absorption, reduced inflammation, hormonal health. | Poppy, olive oil, nuts, salmon, chia seeds and flax |
Nutritional periodicization: your diet changes with the season
You don't eat the same in preseason as in full competition, nor the same on a double session day as on a rest day. Nutritional periodization and is one of the most important principles of modern sports nutrition.
High demand: double sessions, a lot of training volume. You need more calories and more carbohydrates (6-8 g/kg). High protein to repair the muscle damage of intense training. Maximum hydration — players can lose up to 5 liters of liquid per day in preseason.
Adjust according to the calendar: high carb match days, moderate training days, lower rest days. The priority is to maintain performance and recovery between matches. Constant protein (1.6-2.0 g/kg) throughout the season.
Reduce total calories according to the lowest activity. Keep the protein so you don't lose muscle mass. It's a good time to work body composition if you need to lose fat — but gradually and controlled, never with extreme restrictive diets.
Match day: the full protocol
| Moment | What to eat | Example: |
|---|---|---|
| 3-4 hours before | Complete food: complex carbohydrates + moderate protein + low fat and fiber (to avoid digestive discomfort). | Grilled chicken with rice and steamed vegetables. Pasta with tomato sauce and tuna. Whole toasted with scrambled egg and banana. |
| 1-2 hours before | Light cooling: easy to digest carbohydrates. | Banana with honey. Cereal bar. Toast with jam. Fruit smoothie. |
| In between time | Fast carbohydrates + electrolyte hydration. | Half banana, orange slices, energy gel, sports drink. |
| Within 60 min post-game | Recovery: 1-1.5 g/kg carbohydrate + 20-40 g high quality protein + rehydration. | Protein shake with banana and oatmeal. Chicken with rice and vegetables. Salmon with potato and salad. |
Day of training vs day of rest
Intense training day: Prioritize carbohydrates — especially before and after the session. A 75 kg player should consume between 375 and 525 grams of carbohydrates on a strong workout day (5-7 g/kg). Protein distributed in 4-5 meals throughout the day.
Rest day: Reduce carbohydrates (3-4 g/kg) and keep the protein. Take advantage to include more vegetables, healthy fats, and anti-inflammatory foods (fatty fish, red fruits, nuts). The rest day is to recover — and nutrition is part of that recovery.
Hydration: the most underestimated variable
- A footballer may lose more than 1 litre of sweat per hour during a match, and more in conditions of heat and humidity.
- One 2 % dehydration body weight already affects cognitive function, reaction rate, and physical performance.
- Before the game: 500-600 ml water 2-3 hours before + 200-300 ml 15-30 minutes before start.
- During the game: Take advantage of each pause (intertime, hydration break) to drink water or drink with electrolytes.
- After the game: Respond ~1,000 ml of liquid for each hour of exercise. Includes electrolytes (sodium, potassium, magnesium) — not just pure water.
- Elite players can lose 1-3 grams of sodium per hour Add salt to your meals or use electrolyte pills to replenish the lost.
Supplements: Which have evidence
The rule is food first, supplements after — and only those with solid scientific evidence. If your diet is good, supplements are marginal; if your diet is bad, no supplement compensates for it.
| Supplement | Evidence | Note |
|---|---|---|
| Protein (whey) | Solid. Suitable for post-training when you can't eat a full meal. | It’s not magic — it’s just a practical source of protein. You can replace it with real foods. |
| Creatine | Solid. Improves strength, power and ability to repeat sprints. | 3-5 g/day. One of the most studied and safe supplements. |
| Caffeine | Solid. Improved concentration, alertness and resistance to fatigue. | 3-6 mg/kg, 30-60 min before stress. Do not use it every day to maintain the effect. |
| Vitamin D | Moderate. Important for bone health, especially if you train indoors or at high latitudes. | Do a blood test first, supplement only if you're deficient. |
| Omega-3 | Moderate. Reduces inflammation and supports joint health. | Better from natural sources (salmon, sardines). Supplement if you do not eat fish regularly. |
| Electrolytes | Solid for rehydration. | Essentials in warm climates and during preseason. Prioritizes sodium and potassium. |
Common nutritional errors
Sauté breakfast. Breakfast is the first fuel load of the day. If you train in the morning without breakfast, you are using the glycogen reserves you should be replenishing.
Eat soon after training. The post-training window exists. Your muscles need carbohydrates and protein to recover. If you wait 3-4 hours to eat, you lose efficiency in recovery.
Remove carbohydrates. Low carb diets are not for footballers. You need glycogen for sprints, directional changes, and high intensity efforts. If you reduce carbohydrates a lot, your performance in the second half of the game will fall.
Moisturize with water alone. In intense workouts and matches, water alone is not enough. You need electrolytes (especially sodium) to replace what you lose in sweat.
Depending on supplements instead of real food. A protein shake does not replace a full meal. Supplements supplement a good diet — they do not replace it.
