Understanding Macros

Macronutrients (macros) are the three main nutrients that provide energy to your body: protein, carbohydrates, and fat. Each plays a unique and important role in your health and fitness:

Protein (4 calories per gram)

Essential for building and repairing muscle tissue, immune function, and enzyme production. High protein foods include meat, fish, eggs, dairy, legumes, and protein supplements.

Fat (9 calories per gram)

Important for hormone production, brain health, and absorption of fat-soluble vitamins. Healthy sources include avocados, nuts, seeds, olive oil, and fatty fish.

Carbohydrates (4 calories per gram)

Your body's preferred energy source, especially for high-intensity activities. Found in grains, fruits, vegetables, legumes, and dairy.

Why Macro Ratios Matter

Different macro ratios can help you achieve different goals:

  • Higher protein helps preserve muscle during weight loss and supports muscle growth
  • Higher fat can improve satiety and works well for some people's metabolism
  • Higher carb can support intense training and athletic performance

The best macro ratio is ultimately the one that:

  1. Helps you achieve your fitness goals
  2. Keeps you feeling energized and satisfied
  3. You can maintain consistently

Important Note

While tracking macros can be very effective, remember that food quality matters too. Focus on nutrient-dense whole foods for the majority of your intake for optimal health and results.
