What You'll Find in "Nutrition Guides: Step-by-Step Handbooks"

Welcome to SportZone Academy! Here you will discover practical guides for building sustainable nutritional habits. This isn't about magic diets, but about science-based strategies that work. No complex theories or empty promises.

We will teach you how to calculate your own caloric needs and distribute macronutrients (proteins, carbohydrates, fats) according to your goals. Whether you want to gain muscle mass, lose fat, or simply feel healthier and more energetic, you will find specific guidance here. Everything is presented step-by-step, in understandable language.

We will show you how to create a weekly meal plan (meal prep) and how to read food labels. Our goal is to give you the knowledge and confidence to control your nutrition. This way, you will achieve results not only in the gym but also in your daily life.

Key Topics

Calculating Caloric Needs: Your Personal Formula for Success

The first step toward any nutritional goal is knowing how many calories you need. There is no universal formula, but we can use proven methods for a personalized assessment. One of the most accurate is the Mifflin-St Jeor formula.

It calculates your Basal Metabolic Rate (BMR), which is the number of calories your body burns at rest. To the BMR, we add an activity factor to get your Total Daily Energy Expenditure (TDEE). This is the number of calories you need to maintain your current weight.

Mifflin-St Jeor Formula:

• For men: (10 x weight in kg) + (6.25 x height in cm) – (5 x age in years) + 5
• For women: (10 x weight in kg) + (6.25 x height in cm) – (5 x age in years) – 161

After calculating your BMR, multiply it by the appropriate activity factor:

• Little to no physical activity: BMR x 1.2
• Light activity (1-3 times per week): BMR x 1.375
• Moderate activity (3-5 times per week): BMR x 1.55
• Heavy activity (6-7 times per week): BMR x 1.725
• Very heavy activity (twice a day, heavy physical labor): BMR x 1.9

The resulting value is your TDEE. We will use this as a starting point to determine the calories for weight loss, maintenance, or muscle gain. For weight loss, we typically recommend a deficit of 300-500 calories below TDEE. For mass gain, a surplus of 200-400 calories above TDEE.

Creating a Daily Plan: Structure and Flexibility

Once you know how many calories and macronutrients you need, it's time to organize them into a daily plan. There is no single rule for the number of meals. You can eat 3, 4, 5, or even 6 times a day. The important thing is to meet your daily goals and feel comfortable.

We suggest you start with 3-4 main meals, plus 1-2 snacks. Distribute your macronutrients evenly among them. For example, if your goal is 160 grams of protein, try to have 30-40 grams in each larger meal.

Include a variety of whole, unprocessed foods. Focus on whole grains, lean proteins, healthy fats, and plenty of vegetables. You don't have to eat the same thing every day. Learn to be flexible and substitute foods to maintain your interest.

Macronutrient Distribution by Goal: Proteins, Carbohydrates, Fats

Macronutrients are your body's fuel. Their proportions depend on your goal.

Protein: The Primary Building Block

Protein is key for muscle growth and repair, especially if you train actively. The recommended intake is:

• For hypertrophy (muscle mass gain): 1.6 - 2.2 grams per kilogram of body weight. For example, if you weigh 80 kg, this is 128-176 grams of protein daily.
• For weight loss and muscle preservation: 1.8 - 2.5 grams per kilogram of body weight. A high protein intake promotes satiety and protects muscle mass during a caloric deficit.
• For general health: 1.0 - 1.6 grams per kilogram of body weight.

Sources: chicken, turkey, beef, fish, eggs, dairy products, legumes, soy, protein powder (whey, casein, plant-based).

Carbohydrates: Energy for Workouts and Daily Life

Carbohydrates are the main source of energy. Their amount depends on your activity level and other macronutrients.

• For hypertrophy: 3-5 grams per kilogram of body weight. They provide energy for intense workouts and support recovery.
• For weight loss: 1-3 grams per kilogram of body weight, depending on your caloric deficit and preferences.

Sources: rice, potatoes, oats, whole-wheat bread, fruits, vegetables.

Fats: Hormonal Health and Vitamin Absorption

Fats are important for hormonal balance, the absorption of fat-soluble vitamins, and overall health. Even when losing weight, do not eliminate them completely. A minimum of 0.8-1.0 grams per kilogram of body weight is a good starting point.

• For all goals: 20-30% of total calories or 0.8 - 1.2 grams per kilogram of body weight.

Sources: avocado, nuts, seeds, olive oil, olives, fatty fish.

Example of macronutrient distribution (80 kg person, hypertrophy goal, 2800 calories):

• Protein: 2.0 g/kg * 80 kg = 160 g of protein (160 g * 4 kcal/g = 640 kcal)
• Fats: 0.9 g/kg * 80 kg = 72 g of fat (72 g * 9 kcal/g = 648 kcal)
• Carbohydrates: (2800 kcal - 640 kcal - 648 kcal) / 4 kcal/g = 1512 kcal / 4 kcal/g = 378 g of carbohydrates (about 4.7 g/kg)

This is just an example. Your needs may differ, but the principles remain the same.

Meal Prep: Effective Planning for Consistency

Meal prep (preparing food in advance) is the secret weapon of many successful athletes and people with busy schedules. It saves you time, money, and most importantly, helps you stick to your nutrition plan. When you have healthy food ready, you are less likely to reach for fast and unhealthy options.

How to start with meal prep:

• Plan your menu: Set aside 15-20 minutes at the beginning of the week to decide what you will eat. Include variety, but also repetitions, so you don't have to cook too many different things.
• Make a shopping list: Buy only what you need for your plan. This will save you money and reduce temptations.
• Choose a cooking day: Most people choose Sunday afternoon or evening. Set aside 2-3 hours.
• Cook in bulk: Cook large quantities of proteins (chicken breast, beef, fish), carbohydrates (rice, potatoes, quinoa), and vegetables.
• Portion into containers: Portion your food into individual reusable containers. This way, you'll have a ready-made meal for each day. Store in the refrigerator (for up to 4-5 days) or freezer.

Example of a meal prep menu: baked chicken breast, brown rice, and broccoli. Or turkey meatballs, sweet potatoes, and spinach. The variations are endless.

Reading Food Labels: Understand What You Eat

Food labels are your window into the content of products. Once you learn to read them, you will be able to make informed choices. Don't just trust the front of the package and the marketing messages.

Key things to look for:

• Serving size: This is the first and most important thing. All values on the label are per serving. Often, one package contains several servings.
• Calories: The total amount of energy.
• Macronutrients: Total fat, saturated fat, carbohydrates (of which sugars), protein. Pay attention to the sugar content—look for products with low added sugar.
• Fiber: Important for digestion and satiety. Aim for over 25 grams of fiber daily.
• Ingredients: The ingredient list is ordered by quantity from largest to smallest. Look for whole, unprocessed ingredients. Avoid long lists of unfamiliar terms, especially at the beginning of the list.
• Added sugar: Manufacturers often use different names for sugar (glucose syrup, corn syrup, dextrose, maltodextrin, etc.). Be careful.

With practice, you will be able to scan labels quickly and choose healthier options for yourself.
