Understanding Macronutrients

Macronutrients are the three main nutrients your body needs in large amounts: carbohydrates, proteins, and fats. Each plays a crucial role in your health and fitness goals.

🍞 Carbohydrates (4 cal/g)

Your body's primary energy source. Essential for brain function and high-intensity exercise. Found in grains, fruits, vegetables, and legumes.

🥩 Protein (4 cal/g)

Building blocks for muscle, skin, and organs. Critical for muscle growth and repair. Found in meat, fish, eggs, dairy, and plant sources.

🥑 Fats (9 cal/g)

Essential for hormone production and nutrient absorption. Provides long-lasting energy. Found in oils, nuts, seeds, and fatty fish.

⚖️ Balanced (40/30/30)

Great for general fitness and health maintenance. Provides steady energy and supports muscle growth while allowing dietary flexibility.

🥩 Low-Carb (20/40/40)

Effective for weight loss and blood sugar control. Higher protein supports muscle preservation during calorie restriction.

🍝 High-Carb (60/20/20)

Ideal for endurance athletes and those with high activity levels. Maximizes glycogen stores for sustained energy.

🧈 Keto (5/20/75)

Promotes ketosis for rapid fat loss. Very low carbs force the body to use fat as its primary energy source.
