However, calorie requirements vary for each individual, so it's essential to focus on healthy eating habits rather than just numbers.

A balanced diet is more important than calorie count! Here’s how to nourish your body for optimal growth and energy.

1️⃣ Fruits & Vegetables 🥦🍓

✔ Essential for vitamins, antioxidants, and fiber.

✔ Helps with digestion, immunity, and overall health.

✔ Aim for at least 5 servings per day.

2️⃣ Whole Grains 🍞🍚

✔ Provides sustained energy for school, sports, and activities.

✔ Includes brown rice, oats, quinoa, whole-wheat bread & pasta.

✔ Low-glycemic index grains help keep you full longer.

3️⃣ Lean Proteins 🥩🐟

✔ Supports muscle growth and development.

✔ Includes chicken, fish, eggs, beans, lentils, tofu, nuts, and dairy.

✔ Essential for building strong bones & repairing tissues.

4️⃣ Dairy & Dairy Alternatives 🥛🧀

✔ Provides calcium for strong bones and teeth.

✔ Includes milk, yogurt, cheese, or plant-based alternatives like almond milk.

✔ Teens need extra calcium to build bone mass for adulthood.

5️⃣ Healthy Fats 🥑🥜

✔ Supports brain function and hormone production.

✔ Found in avocados, nuts, seeds, olive oil, and fatty fish (like salmon).

✔ Avoid processed and trans fats (found in fried & packaged foods).

📌 Pro Tip:Limit sugary drinks & processed snacks—they add empty calories without real nutrition.

✔ To lose weight safely, a 500-calorie deficit per day is recommended.

✔ This helps burn fat gradually without harming growth or metabolism.

✔ Example: If a teen usually eats 2,400 calories per day, they should aim for 1,900 calories instead.

📌 Important:Teenagers should NOT follow extreme diets. Instead, focus on:

✔ Balanced meals with more protein & fiber.

✔ Reducing sugary drinks & junk food.

✔ Staying active with exercise or sports.

The more active a teen is, the more calories they need!

📌 Example: A 15-year-old basketball player training 5+ days a week may need 3,500+ calories per day to maintain energy levels and muscle mass.
