Macro Calculator

Protein (4 calories per gram)

• Essential for muscle protein synthesis and repair
• Helps maintain muscle mass during weight loss
• Has the highest thermic effect (burns calories to digest)
• Promotes satiety and helps control hunger
• Sources: meat, fish, eggs, dairy, legumes, protein powder

Carbohydrates (4 calories per gram)

• Primary energy source for high-intensity exercise
• Fuels brain function and central nervous system
• Helps with muscle recovery and glycogen replenishment
• Supports intense training and athletic performance
• Sources: grains, fruits, vegetables, legumes, dairy

Fats (9 calories per gram)

• Essential for hormone production (testosterone, estrogen)
• Supports absorption of fat-soluble vitamins (A, D, E, K)
• Provides sustained energy for low-intensity activities
• Important for brain health and cognitive function
• Sources: oils, nuts, seeds, avocado, fatty fish

Balanced (25/45/30)

A well-rounded approach suitable for most people. Provides adequate protein for muscle maintenance, sufficient carbs for energy and performance, and healthy fats for hormone production. Great starting point for beginners.

High Protein (35/35/30)

Emphasizes protein intake for muscle building, fat loss, and satiety. Moderate carbs support training while higher protein helps preserve muscle during caloric deficits. Popular for body recomposition goals.

Low Carb (30/20/50)

Reduces carbohydrates while increasing fats. Can help with fat loss and may improve insulin sensitivity. Requires adaptation period. Not ideal for high-intensity training or athletes.

Ketogenic (25/5/70)

Very low carb, high fat approach that aims to induce ketosis. Body burns fat and ketones for fuel instead of glucose. Requires strict adherence and medical supervision. Not suitable for everyone.

High Carb (20/60/20)

Emphasizes carbohydrates for fuel-dependent activities. Great for endurance athletes, high-volume training, or those who perform better on higher carbs. Lower fat intake requires careful planning.

Bodybuilding (40/40/20)

Very high protein for maximum muscle protein synthesis. Moderate carbs support training. Lower fat but still adequate for health. Used by physique competitors and serious bodybuilders.

Fat Loss

• Protein: 1.2-1.6g per kg body weight (higher end in deficit)
• Fat: 0.8-1.2g per kg body weight (minimum for health)
• Carbs: Fill remaining calories, adjust based on training needs
• Priority: High protein to preserve muscle, moderate fats for hormones

Muscle Building

• Protein: 1.6-2.2g per kg body weight for optimal MPS
• Carbs: 4-6g per kg body weight to fuel training
• Fat: 0.8-1.2g per kg body weight for hormone production
• Priority: Adequate calories with sufficient protein and carbs

Athletic Performance

• Carbs: 5-10g per kg body weight depending on training volume
• Protein: 1.4-2.0g per kg body weight for recovery
• Fat: 1.0-1.5g per kg body weight for health and satiety
• Priority: Carbs for performance, protein for recovery

General Health

• Protein: 0.8-1.2g per kg body weight (RDA and above)
• Carbs: 45-65% of calories from quality sources
• Fat: 20-35% of calories, emphasizing unsaturated fats
• Priority: Balanced approach with whole foods

Getting Started

• Start with a balanced approach and adjust based on results
• Track food intake for 1-2 weeks to understand current patterns
• Focus on whole, minimally processed foods first
• Don't obsess over exact numbers - consistency matters more

Meal Timing and Distribution

• Spread protein evenly throughout the day (20-40g per meal)
• Time carbs around workouts for better performance and recovery
• Include some fat with each meal for satiety and nutrient absorption
• Post-workout meals can be higher in protein and carbs

Tracking and Adjustments

• Use a food tracking app for accuracy in the beginning
• Weigh foods when possible, especially calorie-dense items
• Adjust macros based on progress, energy levels, and performance
• Allow for flexibility and don't stress over perfect adherence

Quality Matters

• Choose lean proteins, complex carbs, and healthy fats
• Include plenty of fruits and vegetables for micronutrients
• Stay hydrated - often overlooked but crucial for performance
• Consider nutrient timing around training for optimal results
