🥗 What are Macronutrients?

Macronutrients are the nutrients your body needs in large amounts: protein, fats, and carbohydrates. Each macronutrient plays a unique role in your body:

Protein (4 cal/g): Builds and repairs muscle, produces enzymes and hormones, supports immune function.
Fats (9 cal/g): Provides energy, supports cell growth, protects organs, helps absorb fat-soluble vitamins.
Carbohydrates (4 cal/g): Primary energy source for your brain and body, especially during exercise.

📊 Understanding Macro Ratios

Balanced (30/30/40): Good for general health and maintenance. Suitable for most people.
High Protein (40/25/35): Ideal for muscle building, fat loss, and athletes. Helps preserve muscle during calorie deficit.
Low Carb / Keto (25/40/35): Popular for weight loss and metabolic health. Limits carbs to encourage fat burning.
High Carb (20/20/60): For endurance athletes or those with high energy demands.

💡 Tips for Tracking Macros

Use a food tracking app like MyFitnessPal or Cronometer
Weigh and measure your food for accuracy
Prioritize whole foods over processed options
Adjust macros based on your progress (every 4-6 weeks)
Stay hydrated and get adequate sleep for best results

❓ Frequently Asked Questions (FAQ)

What is the best macro ratio for weight loss?

A high protein ratio (40% protein, 30% fat, 30% carbs) is often best for weight loss. Protein increases satiety, preserves muscle mass, and has a higher thermic effect of food (burns more calories during digestion).

Do I need to count macros to lose weight?

Not necessarily. Calorie deficit is what matters for weight loss. However, tracking macros helps ensure you're getting adequate protein to preserve muscle and enough carbs for energy.

How much protein do I need for muscle gain?

For muscle gain, aim for 1.6-2.2 grams of protein per kilogram of body weight (0.7-1.0 g per lb). Our high protein ratio (40%) is designed to meet this requirement.

What is IIFYM (If It Fits Your Macros)?

IIFYM is a flexible dieting approach where you can eat any foods as long as you hit your daily macro targets. While flexible, prioritizing nutrient-dense whole foods is still recommended for health.

Should I adjust macros on rest days vs workout days?

Some people reduce carbs on rest days since energy demands are lower. This is optional. A simpler approach is to keep macros consistent daily unless you're an advanced athlete.

How often should I recalculate my macros?

Every 4-6 weeks or after losing/gaining 5-10 lbs. As your weight changes, your calorie needs change. Our calculator helps you adjust accordingly.
