In chicken breast, protein makes up ~75% of calories. This is an ideal food for muscle mass growth (bulking) and fat loss (cutting). One 200 g portion provides 62 g of protein — more than half the daily requirement for an 80 kg athlete.
Chicken contains all EAAs (essential amino acids), including leucine — the main trigger of muscle protein synthesis. A 200 g portion of chicken provides ~5 g of leucine, which exceeds the 'leucine threshold' (2.5–3 g) for maximal stimulation of muscle synthesis.
Due to its exceptionally high protein density and low calorie content, chicken provides a feeling of fullness with minimal calories. This helps maintain a calorie deficit without hunger and protects muscle mass during weight loss.
Chicken can be fried, boiled, stewed, grilled, baked in the oven, or cooked in a slow cooker. It is suitable for salads, sandwiches, soups, and wraps. For meal prep — it keeps in the refrigerator for 4 days.
💡 Professional tip: Marinate chicken in Greek yogurt with seasonings for 2–4 hours before baking. The yogurt acid tenderizes the meat, and the protein from the yogurt enriches the dish. The chicken will be juicier even if slightly overcooked.
Breast has more protein and less fat (31 g protein, 3.6 g fat). Thighs have slightly more fat (8 g) but are juicier and cheaper. Both options are suitable — choose according to your calorie goals.
Yes, chicken is safe for daily consumption. However, dietary variety is important — alternate it with fish, eggs, beef, and legumes to get a broader range of micronutrients.
It depends on your weight and goals. An 80 kg athlete needs ~130–175 g of protein per day, so 300–400 g of chicken breast per day (divided into 2–3 portions) is a reasonable amount together with other sources.
Baked in the oven, grilled, or steamed — yes. Fried in oil in a deep fryer — avoid. The best methods: oven, grill, steam, stewing. Use seasonings, lemon juice, and garlic for flavor without extra calories.
Consume 1.6–2.2 g/kg body weight per day for muscle growth and recovery. Distribute protein evenly across 3–5 meals.
The main energy source for intense training. 3–7 g/kg depending on the sport and intensity.
Healthy fats from nuts, fish, avocados — for hormone production and joint health. 0.8–1.2 g/kg per day.
Drink 30–40 ml of water per 1 kg of body weight. During training, additionally 500–1000 ml per hour with electrolytes.
