Nutrition for Physically Active People
Training is only half the battle—the other half is proper nutrition. You can train as hard as you can, but without a proper diet, you won't achieve optimal results. In this guide, you'll learn how to eat to support your training goals, recovery, and overall health.
Basics of Sports Nutrition
Macronutrients - The Foundation of the Diet
1. Protein - The Building Block of Muscles
The most important macronutrient for active people.
How much do you need?
- Active people: 1.6-2.2g per kg of body weight
- Strength training: 2.0-2.4g/kg
- Endurance training: 1.4-1.8g/kg
- Reduction: 2.0-2.5g/kg (protects muscles)
Best sources:
- Lean meat (chicken, turkey, beef)
- Fish (tuna, salmon, cod)
- Eggs (complete amino acids)
- Dairy products (cottage cheese, Greek yogurt, cheese)
- Plant-based: tofu, tempeh, seitan, legumes
- Whey protein (convenient supplement)
2. Carbohydrates - Fuel for Training
The main source of energy, especially important for intense training.
How much do you need?
- Low activity: 3-5g/kg
- Average activity: 5-7g/kg
- High activity: 7-10g/kg
- Very high (athletes): 10-12g/kg
Best sources:
- Composed of: Rice (white and brown), groats, oats, quinoa, potatoes, sweet potatoes
- Simple (around training): Bananas, dates, honey, white rice
- Fiber: Vegetables, fruits, whole grains
3. Fats - Hormones and Health
Crucial for hormone production, vitamin absorption and overall health.
How much do you need?
- Minimum: 0.8-1.0g/kg
- Optimal: 1.0-1.5g/kg
- 20-35% of total calories
Best sources:
- Unsaturated: Olive oil, avocado, nuts, seeds, fatty fish
- Omega-3: Salmon, mackerel, flaxseed, walnuts
- Saturated (moderate): Coconut oil, butter, egg yolks
Nutrition Around Training
Before Training (1-3 hours before)
Goals:
- Provide energy
- Prevent hunger during training
- Minimize muscle catabolism
What to eat:
- Complex carbohydrates + protein
- Low/medium glycemic index
- Low in fat and fiber (slower digestion)
Examples of meals:
- Oatmeal with protein and banana
- Chicken with rice and vegetables
- Whole wheat toast with egg and avocado
- Greek yogurt with fruit and honey
- Protein shake with oats and peanut butter
30-60 minutes before training (optional):
- Banana
- Dates
- Protein shake
- Energy bar
Post-Workout (30-60 minute "anabolic window")
Goals:
- Replenish glycogen
- Start rebuilding your muscles
- Speed up regeneration
What to eat:
- Protein: 20-40g
- Carbohydrates: 0.5-1.0g/kg (depending on intensity)
- Carbohydrate:protein ratio = 2:1 to 4:1
Examples of meals:
- Protein shake with banana and honey
- Chicken with white rice
- Scrambled eggs with bread
- Tuna with groats
- Cottage cheese with fruit
- Shake: protein + banana + oats + peanut butter
Hydration - An Underrated Element
Why is water so important?
- 70% of muscles are water
- Dehydration 2% = 10-20% drop in performance
- Affects strength, endurance and concentration
- Key to regeneration
How much to drink?
- Basis: 30-40ml per kg of body weight
- Before training: 400-600ml (2-3 hours before)
- During training: 200-300ml every 15-20 minutes
- Post-workout: 150% body weight lost
Signs of dehydration:
- Dark urine
- Desire (too late!)
- Tiredness
- Headaches
- Decreased performance
Isotonic drinks - when?
- Workouts longer than 60-90 minutes
- Intensive training in the heat
- Heavy sweating
- Replenish electrolytes (sodium, potassium, magnesium)

Nutrition for Various Purposes
Building Muscle Mass (Mass):
- Caloric surplus: +300-500 kcal
- Protein: 2.0-2.4g/kg
- Carbohydrates: high (5-7g/kg)
- Fats: 1.0-1.2g/kg
- Frequent meals (5-6 a day)
Fat Reduction:
- Calorie deficit: -300-500 kcal
- Protein: 2.0-2.5g/kg (protects muscles)
- Carbohydrates: moderate (3-5g/kg)
- Fats: 0.8-1.0g/kg
- Priority: protein and vegetables
Maintenance/Recomposition:
- Maintenance Calories
- Protein: 1.8-2.2g/kg
- Carbohydrates: 4-6g/kg
- Fats: 1.0-1.2g/kg
- Strength training + slight deficit
Supplements - What to Consider?
Basic (scientifically proven):
1. Whey Protein
- Convenient protein supplement
- Quickly absorbed
- Perfect after training
- 20-30g per serving
2. Creatine
- The most researched supplement
- Increases strength and muscle mass
- Monohydrate 5g per day
- Safe and effective
3. Caffeine
- Increases energy and concentration
- Improves performance
- 3-6mg/kg before training
- Be careful with tolerance
4. Omega-3
- Anti-inflammatory properties
- Heart and brain health
- 2-3g EPA+DHA daily
5. Vitamin D
- Most are deficient
- Important for bones, muscles, immunity
- 2000-4000 IU per day
Optional:
- BCAA (if low protein intake)
- Beta-alanine (endurance)
- Citrulline (muscle pump)
- Magnesium (regeneration, sleep)
The Most Common Nutritional Mistakes
1. Not enough protein
Muscles need protein to rebuild. At least 1.6g/kg!
2. Skipping a meal after training
The anabolic window exists - use it!
3. Too few calories for bulking
Without a surplus you won't build muscle effectively.
4. Too large a deficit on reduction
You'll lose muscle instead of fat. 300-500 kcal is enough.
5. Poor hydration
Water is essential - don't neglect it!
6. Lack of planning
Prepare your meals in advance - meal prep!
Meal Prep
Benefits:
- Saving time
- Diet control
- Less temptation
- Saving money
How to get started:
- Sunday = cooking day
- Prepare 3-4 meals for 3-4 days
- Divide into boxes
- Store in the refrigerator/freezer
Basic meal prep ingredients:
- Protein: chicken, turkey, beef, fish
- Carbohydrates: rice, groats, potatoes, sweet potatoes
- Vegetables: broccoli, spinach, peppers, carrots
- Fats: olive oil, nuts, avocado
Summary
A diet for active people doesn't have to be complicated. Key principles:
- Sufficient protein (1.6-2.2g/kg)
- Carbohydrates adapted to activity
- Healthy fats (1.0-1.5g/kg)
- Hydration (3-4 liters per day)
- Pre- and post-workout meal
- Regularity and planning
Remember: diet is 70% of success. You can train like a top athlete, but without proper nutrition, you won't achieve your goals. Start with the basics, be consistent, and see the results!
Your body is a reflection of what you eat. Feed it wisely!
