🎓 Understanding Macronutrients

What Are Macronutrients?

Macronutrients (macros) are the three main categories of nutrients that provide energy and support bodily functions:

đŸĨŠ

Protein

4 calories per gram

  • Builds and repairs tissue
  • Maintains muscle mass
  • Supports immune function
  • Increases satiety
🌾

Carbohydrates

4 calories per gram

  • Primary energy source
  • Fuels brain and muscles
  • Supports recovery
  • Spares protein
đŸĨ‘

Fats

9 calories per gram

  • Hormone production
  • Nutrient absorption
  • Cell membrane structure
  • Long-term energy

Protein Requirements by Goal

Goal Protein per kg Protein per lb Notes
Sedentary adult 0.8-1.0g 0.36-0.45g Minimum for health
Recreational athlete 1.2-1.4g 0.54-0.64g Active lifestyle
Endurance athlete 1.2-1.6g 0.54-0.73g High training volume
Strength athlete 1.6-2.2g 0.73-1.0g Muscle building focus
Fat loss 2.0-2.6g 0.91-1.18g Preserve muscle in deficit

⏰ Macro Timing Strategies

🏋ī¸ Pre-Workout

  • Carbs: 15-30g for energy
  • Protein: 10-20g for muscle protection
  • Fats: Minimal (slow digestion)
  • Timing: 30-60 minutes before

🏆 Post-Workout

  • Carbs: 20-40g for recovery
  • Protein: 20-30g for muscle synthesis
  • Fats: 5-10g (don't avoid completely)
  • Timing: Within 2 hours

Common Macro Mistakes

⚠ī¸ Avoid These Pitfalls

  • Too low protein: Leads to muscle loss and poor recovery
  • Extreme approaches: Very low carb or fat diets are hard to sustain
  • Ignoring fiber: Aim for 25-35g daily from carb sources
  • All-or-nothing mindset: 80% consistency beats 100% for 2 weeks
  • Not adjusting for activity: Increase carbs on training days

💡 Pro Tip: Start with our calculated macros and track for 2-3 weeks. Adjust based on energy levels, performance, hunger, and body composition changes. The best macro split is the one you can stick to consistently while reaching your goals.

Frequently Asked Questions

Should I track macros or just calories?

For weight loss, calories matter most. However, tracking macros ensures adequate protein for muscle preservation, enough carbs for energy, and sufficient fats for hormones. It leads to better body composition and performance results.

What if I can't hit my macros perfectly?

Aim for Âą5g on protein and Âą10g on carbs/fats. Focus on hitting protein first, then distribute carbs and fats based on preference. Being 80-90% consistent is better than perfect for 2 weeks then quitting.

Do I need different macros on rest days?

You can keep macros the same for simplicity, or reduce carbs by 20-30% on rest days while keeping protein constant. Some prefer higher fats on rest days for satiety and hormone support.

What's the best macro ratio for fat loss?

There's no single best ratio. Higher protein (30-40%) helps preserve muscle and increases satiety. Whether you prefer lower carbs or lower fats depends on personal preference, training style, and adherence.

How often should I recalculate my macros?

Recalculate every 10-15 lbs of weight change, or if your activity level changes significantly. Most people benefit from small adjustments every 4-6 weeks based on progress and feedback.

Can I eat anything as long as it fits my macros (IIFYM)?

While IIFYM works for body composition, food quality matters for health, energy, and satiety. Aim for 80% whole foods and 20% flexibility for best results and sustainability.
