How much protein should I eat per day?

Protein needs vary by activity level and goals. Generally, sedentary adults need 0.8g per kg of body weight, while active individuals may need 1.2-2.2g per kg. Athletes and those building muscle typically require 1.6-2.2g per kg of body weight.

What are the best macro ratios for weight loss?

For weight loss, a moderate approach is 40% carbs, 30% protein, and 30% fat. Higher protein (40%) can help preserve muscle mass during caloric restriction, while lower carbs (30%) may improve fat loss for some individuals.

How do I calculate macros for muscle gain?

For muscle gain, aim for higher protein (25-35% of calories), moderate carbs (35-45%), and adequate fats (20-30%). Protein should be 1.6-2.2g per kg body weight, with sufficient calories above maintenance to support muscle growth.

What are keto macro ratios?

Standard ketogenic diet macros are approximately 70-80% fat, 15-25% protein, and 5-10% carbohydrates. This typically means less than 20-50g of net carbs per day to maintain ketosis.

Should I track net carbs or total carbs?

Net carbs (total carbs minus fiber) are often more relevant for blood sugar impact and ketosis. However, total carbs matter for overall calorie counting. Our calculator shows both to help you make informed decisions.

Complete Macronutrient Guide: Optimizing Your Diet

🥩 Understanding Macronutrients

Macronutrients are the three main nutrient categories your body needs in large amounts to function properly and achieve your fitness goals.

Protein - Building Blocks

• Calories: 4 calories per gram
• Function: Muscle repair, enzyme production, immunity
• Daily Need: 1.6-2.2g per kg for athletes, 0.8g minimum
• Sources: Chicken, fish, eggs, Greek yogurt, tofu

Carbohydrates - Energy Source

• Calories: 4 calories per gram
• Function: Primary energy, brain fuel, glycogen storage
• Daily Need: 3-7g per kg depending on activity
• Sources: Rice, oats, sweet potatoes, fruits, quinoa

Fats - Hormones & Absorption

• Calories: 9 calories per gram
• Function: Hormone production, vitamin absorption, satiety
• Daily Need: 0.8-1.2g per kg body weight
• Sources: Avocado, nuts, olive oil, salmon, eggs

🎯 Goal-Specific Macro Ratios

⚖️ Weight Loss (Fat Loss)

• Protein: 30-40% (high for muscle preservation)
• Carbs: 25-35% (moderate, timing matters)
• Fat: 30-35% (adequate for hormones)
• Strategy: High protein prevents muscle loss in deficit

💪 Muscle Gain (Bulking)

• Protein: 25-30% (adequate for growth)
• Carbs: 45-55% (fuel for training)
• Fat: 20-25% (hormone support)
• Strategy: Higher carbs support intense training

🔄 Maintenance (Recomp)

• Protein: 25-30% (maintain muscle mass)
• Carbs: 40-50% (energy balance)
• Fat: 25-30% (optimal health)
• Strategy: Balanced approach for long-term health

Goal	Protein %	Carbs %	Fat %
Fat Loss	35%	30%	35%
Maintenance	30%	40%	30%
Muscle Gain	25%	50%	25%

Meal Timing & Nutrient Timing Strategies

⏰ Optimal Meal Timing

🌅 Pre-Workout Nutrition

• Timing: 1-3 hours before training
• Focus: Carbs for energy, moderate protein
• Example: Oatmeal + banana + protein shake
• Purpose: Fuel workout, prevent muscle breakdown

💪 Post-Workout Nutrition

• Timing: Within 2 hours post-workout
• Focus: Fast carbs + protein (3:1 or 2:1 ratio)
• Example: Rice + chicken, or recovery shake
• Purpose: Glycogen replenishment, muscle repair

🌙 Evening Nutrition

• Timing: 2-3 hours before bed
• Focus: Slow-digesting protein, moderate carbs
• Example: Greek yogurt, cottage cheese, casein
• Purpose: Overnight muscle recovery

🍽️ Meal Frequency Strategies

3 Meals Per Day

• Best For: Simplicity, busy schedules
• Pros: Less meal prep, natural eating pattern
• Distribution: 30% / 35% / 35% calories

5-6 Small Meals

• Best For: Bodybuilders, appetite control
• Pros: Stable blood sugar, constant energy
• Distribution: Even 15-20% per meal

Intermittent Fasting (16:8)

• Best For: Fat loss, metabolic health
• Pros: Autophagy, insulin sensitivity, simplicity
• Window: All calories in 8-hour window

💡 Key Insight

Total daily macro intake matters more than meal frequency. Choose the eating pattern that fits your lifestyle and helps you consistently hit your macro targets.

Frequently Asked Questions

Q: Do I need to hit my macros exactly every day?

A: Focus on weekly averages rather than daily perfection. Being within 5-10g of your targets is generally sufficient. Consistency over weeks and months matters more than hitting exact numbers daily. Track trends, not individual days.

Q: Which macro is most important for fat loss?

A: Protein is crucial during fat loss to preserve muscle mass. Aim for 1.6-2.2g per kg body weight. Total calorie deficit drives fat loss, but adequate protein ensures you lose fat, not muscle. Carbs and fats can be adjusted based on preference and performance needs.

Q: Should I adjust macros on rest days vs training days?

A: Advanced strategy: reduce carbs slightly on rest days and increase on training days (carb cycling). Beginners: keep macros consistent daily for simplicity. Protein should stay constant regardless. The key is weekly total intake, not daily variation.

Q: How long until I see results tracking macros?

A: Give any macro strategy 3-4 weeks before judging results. Weight can fluctuate daily due to water, glycogen, and digestion. Track weekly averages and progress photos. If no change after 4 weeks, adjust total calories by 10-15% while maintaining macro ratios.
