What Are Macros? Understanding the Basics
Macronutrients (macros) are the three main nutrients that provide calories: protein, carbohydrates, and fats. Each plays a unique role in your body and has a different caloric value per gram.
Protein: The Building Block (4 calories per gram)
Protein is essential for muscle maintenance, immune function, and keeping you full. It has the highest thermic effect, meaning your body burns more calories digesting protein than other macros.
Primary Functions:
- · Builds and repairs muscle tissue
- · Supports immune system function
- · Creates enzymes and hormones
- · Provides satiety (keeps you full)
- · Preserves muscle during weight loss
Best Protein Sources:
- · Lean meats: Chicken, turkey, lean beef
- · Fish: Salmon, tuna, cod
- · Dairy: Greek yogurt, cottage cheese
- · Plant-based: Tofu, tempeh, legumes
- · Supplements: Whey or plant protein powder
Carbohydrates: The Primary Fuel (4 calories per gram)
Carbs are your body's preferred energy source, especially for your brain and during high-intensity exercise. They also play a crucial role in recovery and hormone production.
Carb Quality Matters
While all carbs provide 4 calories per gram, choosing nutrient-dense sources with fiber will improve satiety, energy levels, and overall health compared to refined sugars.
Primary Functions:
- · Provides quick energy for activities
- · Fuels brain function
- · Supports muscle glycogen storage
- · Aids in protein synthesis
- · Helps produce serotonin (mood regulation)
Quality Carb Sources:
- · Whole grains: Oats, quinoa, brown rice
- · Starchy vegetables: Sweet potatoes, squash
- · Fruits: Berries, apples, bananas
- · Legumes: Black beans, lentils, chickpeas
- · Vegetables: Broccoli, spinach, carrots
Fats: The Essential Nutrient (9 calories per gram)
Despite being the most calorie-dense macro, fats are essential for hormone production, nutrient absorption, and brain health. Quality matters more than quantity.
Primary Functions:
- · Produces hormones (including sex hormones)
- · Absorbs fat-soluble vitamins (A, D, E, K)
- · Provides sustained energy
- · Supports brain health and function
- · Reduces inflammation (omega-3s)
Healthy Fat Sources:
- · Monounsaturated: Olive oil, avocados, nuts
- · Polyunsaturated: Fatty fish, walnuts, flaxseeds
- · Saturated (moderate): Coconut oil, grass-fed butter
- · Omega-3 rich: Salmon, chia seeds, hemp seeds
How to Calculate Your Macro Needs
Calculating your macros involves determining your calorie needs first, then breaking those calories into appropriate percentages of each macronutrient based on your goals.
1
Calculate Your Calorie Needs
Start by determining your Total Daily Energy Expenditure (TDEE) using your basal metabolic rate and activity level.
Quick TDEE Formula:
Men: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age) + 5
Women: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age) - 161
Then multiply by activity factor:
Sedentary: × 1.2 | Lightly active: × 1.375 | Moderately active: × 1.55 | Very active: × 1.725
2
Adjust Calories for Your Goal
Modify your TDEE based on whether you want to lose weight, maintain, or gain muscle.
Fat Loss
TDEE - 300-500 calories
Moderate deficit preserves muscle
Maintenance
Eat at your TDEE
For body recomposition
Muscle Gain
TDEE + 200-500 calories
Controlled surplus for lean gains
3
Choose Your Macro Split
Select macro percentages based on your goals, preferences, and activity level.
Common Macro Splits by Goal:
Fat Loss
30-35%
35-40%
25-30%
Muscle Gain
25-30%
45-50%
20-25%
Endurance
15-20%
55-60%
20-25%
General Health
20-25%
45-50%
25-30%
4
Convert to Grams
Transform your percentages into trackable gram amounts for each macro.
Example Calculation:
2,000 calorie target with 30% protein, 40% carbs, 30% fat:
- • Protein: 2,000 × 0.30 = 600 calories ÷ 4 = 150g protein
- • Carbs: 2,000 × 0.40 = 800 calories ÷ 4 = 200g carbs
- • Fat: 2,000 × 0.30 = 600 calories ÷ 9 = 67g fat

Step-by-Step: How to Track Your Macros
Success with macro tracking comes down to consistency and accuracy. Follow this practical guide to master the basics.
1. Get the Right Tools
Essential Equipment:
- • Food scale: Digital, measures in grams (accuracy is key)
- • Measuring cups/spoons: For liquids and when scale isn't practical
- • Tracking app: Choose one from our comparison above
- • Body weight scale: For tracking progress (optional but helpful)
A food scale is the most important investment--eyeballing portions can be off by 50% or more. Get a scale that toggles between grams and ounces, has a tare function, and can handle at least 5kg.
2. Master the Weighing Process
Weighing Best Practices:
- • Weigh foods raw when possible (most accurate)
- • Use the tare function between ingredients
- • Weigh in grams for precision
- • Log as you cook, not after eating
- • Save frequent meals as recipes
Common Weighing Mistakes:
- • Not weighing calorie-dense foods (oils, nuts)
- • Using "servings" instead of weight
- • Forgetting cooking oils and condiments
- • Weighing cooked food with raw entries
- • Not accounting for food waste (bones, peels)
3. Build Your Tracking Routine
Daily Tracking Timeline:
Morning: Pre-log planned meals for the day
Before meals: Weigh ingredients as you cook
After meals: Adjust quantities if needed
Evening: Review macros and plan tomorrow
Pre-logging your day helps you hit targets without stress. You can always adjust quantities later, but having a plan prevents end-of-day macro tetris.
4. Handle Special Situations
Restaurant Meals:
- • Check online menus for nutrition info beforehand
- • Order simple preparations (grilled, steamed)
- • Ask for dressings and sauces on the side
- • Estimate using similar chain restaurant entries
- • Don't stress about perfect accuracy--do your best
Homemade Recipes:
- • Weigh all ingredients before cooking
- • Weigh the final dish
- • Create recipe in your app
- • Log by weight of your portion
- • Update recipe if you make changes
Macro Tracking for Different Goals
Macro Tracking for Weight Loss
The key to sustainable weight loss is maintaining a moderate calorie deficit while preserving muscle mass through adequate protein intake.
Weight Loss Macro Strategy:
- • Protein: 0.8-1g per lb body weight (preserves muscle)
- • Fat: 0.25-0.35g per lb (hormone support)
- • Carbs: Fill remaining calories (energy for workouts)
- • Deficit: 300-500 calories below TDEE
- • Rate: Aim for 0.5-1% body weight per week
Success Tips:
- • Focus on high-volume, low-calorie foods
- • Prioritize protein at every meal
- • Include fiber-rich carbs for satiety
- • Don't eliminate food groups
- • Plan for occasional treats within macros
- • Take diet breaks every 8-12 weeks
Macro Tracking for Muscle Gain
Building muscle requires a calorie surplus, adequate protein, and sufficient carbs to fuel intense training sessions.
Muscle Gain Macro Strategy:
- • Protein: 0.7-1g per lb body weight
- • Carbs: 1.5-2.5g per lb (fuel for training)
- • Fat: 0.3-0.4g per lb (hormone optimization)
- • Surplus: 200-500 calories above TDEE
- • Rate: 0.5-1 lb gain per month
Timing Considerations:
- • Pre-workout: Carbs + moderate protein
- • Post-workout: Protein + carbs within 2 hours
- • Spread protein across 4-6 meals
- • Higher carbs on training days
- • Don't fear healthy fats
- • Stay hydrated (affects performance)
Macro Tracking for Athletic Performance
Athletes need to fuel their sport-specific demands while maintaining optimal body composition and recovery.
Sport-Specific Needs:
Endurance Sports:
- • Higher carb needs (3-5g per lb)
- • Moderate protein (0.6-0.8g per lb)
- • Focus on workout nutrition
Power/Strength Sports:
- • Higher protein (0.8-1.2g per lb)
- • Moderate carbs (1.5-2.5g per lb)
- • Adequate fats for recovery
Common Macro Tracking Mistakes (And How to Fix Them)
❌ Top Tracking Mistakes
- Not weighing food: Eyeballing leads to 20-50% errors
- Ignoring liquid calories: Coffee drinks, alcohol add up
- Weekend amnesia: Not tracking Friday-Sunday
- Using generic entries: "Medium apple" varies widely
- Forgetting cooking oils: 1 tbsp = 120 calories
- Chasing perfection: 100% accuracy isn't necessary
- Not adjusting: Macros need updates as you change
✅ Tracking Best Practices
- Weigh everything: At least for first 2-4 weeks
- Be consistent: Track good and bad days equally
- Pre-log meals: Plan your day in advance
- Create recipes: Save time on repeat meals
- Track immediately: Don't rely on memory
- Allow flexibility: 80-90% accuracy works
- Review weekly: Adjust based on results
Advanced Macro Strategies
Carb Cycling
Alternating high and low carb days based on training schedule can optimize performance and body composition.
Example 3-Day Cycle:
- • High Day (training): 1.5-2g carbs per lb
- • Moderate Day: 0.75-1g carbs per lb
- • Low Day (rest): 0.3-0.5g carbs per lb
Keep protein consistent, adjust fats inversely to carbs
Refeed Days
Strategic high-carb days during extended dieting can boost metabolism and improve adherence.
- • Increase calories to maintenance or slightly above
- • Boost carbs by 50-100%, reduce fats
- • Schedule every 1-2 weeks during aggressive cuts
- • Time around intense training or social events
Macro Timing
While total daily macros matter most, strategic timing can enhance results.
Pre/Post Workout:
- • 20-40g protein around training
- • 30-60g carbs for intense sessions
- • Minimal fat near workouts
Daily Distribution:
- • Spread protein across 3-5 meals
- • Front-load carbs earlier in day
- • Include fats for satiety at meals

Frequently Asked Questions
Do I need to hit my macros exactly every day?
No! Aim for within 5-10g of your protein target and 5-10% of carb and fat targets. Your weekly average matters more than daily perfection. Some apps like MacroFactor even use rolling averages instead of daily targets.
What if I go over on one macro?
If you're still within your calorie target, don't stress. If you're over on calories, simply get back on track the next day. Don't try to "make up" for it by eating less--this can lead to binge/restrict cycles.
Should I track vegetables?
Yes, track everything for accuracy, but don't stress about going over your targets due to vegetables. The fiber and micronutrients are worth it, and the calorie impact is minimal for non-starchy vegetables.
How often should I adjust my macros?
Review your progress every 2-4 weeks. If you're not seeing expected results after 2-3 weeks of consistent tracking, consider adjusting. Major changes (10%+ of body weight) definitely warrant recalculation.
Is macro tracking safe for everyone?
While generally safe, those with a history of eating disorders should work with healthcare providers. Pregnant/nursing women, children, and those with medical conditions should consult doctors before starting any tracking regimen.
What's the difference between net carbs and total carbs?
Total carbs include all carbohydrates, while net carbs subtract fiber (and sugar alcohols). Most macro trackers use total carbs. Only use net carbs if following a ketogenic diet or if specifically advised by your healthcare provider.
