Counting macros, short for macronutrients, is a popular method for tracking and managing your diet to achieve specific health and fitness goals. Macronutrients are the primary nutrients that provide energy to the body and include carbohydrates, proteins, and fats. This detailed beginner’s guide will walk you through the process of counting macros, including how to calculate your macronutrient needs, track your intake, and adjust your diet for optimal results.
Understanding Macronutrients
Before diving into how to count macros, it’s essential to understand what macronutrients are and their roles in the body.
- Carbohydrates:
- Role: Carbohydrates are the body’s primary source of energy. They are broken down into glucose, which is used to fuel physical activity and brain function.
- Sources: Found in foods like grains, fruits, vegetables, and sugars.
- Recommended Intake: Typically, 45-65% of daily caloric intake.
- Proteins:
- Role: Proteins are essential for building and repairing tissues, producing enzymes and hormones, and supporting immune function.
- Sources: Found in foods like meat, poultry, fish, eggs, dairy, legumes, and nuts.
- Recommended Intake: Typically, 10-35% of daily caloric intake.
- Fats:
- Role: Fats provide energy, support cell growth, protect organs, and are crucial for the absorption of fat-soluble vitamins.
- Sources: Found in foods like oils, butter, avocados, nuts, seeds, and fatty fish.
- Recommended Intake: Typically, 20-35% of daily caloric intake.
Calculating Your Macronutrient Needs
To count macros effectively, you first need to determine your daily caloric needs and the ideal macronutrient breakdown for your goals. Here’s a step-by-step guide to calculating your macronutrient needs:
- Determine Your Basal Metabolic Rate (BMR):
- BMR is the number of calories your body needs to perform basic functions at rest. You can calculate your BMR using the Mifflin-St. Jeor equation:
- For men: BMR = (10 × weight in kg) + (6.25 × height in cm) – (5 × age in years) + 5
- For women: BMR = (10 × weight in kg) + (6.25 × height in cm) – (5 × age in years) – 161
- BMR is the number of calories your body needs to perform basic functions at rest. You can calculate your BMR using the Mifflin-St. Jeor equation:
- Calculate Your Total Daily Energy Expenditure (TDEE):
- TDEE is the total number of calories you burn in a day, including physical activity. Multiply your BMR by an activity factor to estimate your TDEE:
- Sedentary (little to no exercise): BMR × 1.2
- Lightly active (light exercise/sports 1-3 days/week): BMR × 1.375
- Moderately active (moderate exercise/sports 3-5 days/week): BMR × 1.55
- Very active (hard exercise/sports 6-7 days a week): BMR × 1.725
- Extra active (very hard exercise/sports and physical job): BMR × 1.9
- TDEE is the total number of calories you burn in a day, including physical activity. Multiply your BMR by an activity factor to estimate your TDEE:
- Set Your Caloric Goals:
- Based on your fitness goals, adjust your TDEE to create a caloric deficit (for weight loss) or surplus (for weight gain):
- Weight loss: Subtract 300-500 calories from your TDEE.
- Weight gain: Add 300-500 calories to your TDEE.
- Based on your fitness goals, adjust your TDEE to create a caloric deficit (for weight loss) or surplus (for weight gain):
- Determine Your Macronutrient Breakdown:
- Choose a macronutrient breakdown that aligns with your goals. Here are some common macronutrient ratios:
- Balanced diet: 40% carbohydrates, 30% proteins, 30% fats.
- Low-carb diet: 20-30% carbohydrates, 30-40% proteins, 30-40% fats.
- High-protein diet: 30-40% carbohydrates, 40-50% proteins, 20-30% fats.
- Convert the percentages into grams based on your caloric goals:
- Carbohydrates: (Caloric goal × Carbohydrate percentage) / 4
- Proteins: (Caloric goal × Protein percentage) / 4
- Fats: (Caloric goal × Fat percentage) / 9
- Choose a macronutrient breakdown that aligns with your goals. Here are some common macronutrient ratios:
Example Calculation
Let’s walk through an example calculation for a 30-year-old woman who is 5’5″ (165 cm) tall, weighs 150 lbs (68 kg), and is moderately active. Her goal is to lose weight.
- Calculate BMR:
- BMR = (10 × 68 kg) + (6.25 × 165 cm) – (5 × 30 years) – 161 = 1,384 calories/day
- Calculate TDEE:
- TDEE = 1,384 calories/day × 1.55 (moderately active) = 2,143 calories/day
- Set Caloric Goal:
- Caloric goal for weight loss = 2,143 calories/day – 500 calories/day = 1,643 calories/day
- Determine Macronutrient Breakdown:
- Using a balanced diet ratio: 40% carbohydrates, 30% proteins, 30% fats
- Carbohydrates: (1,643 calories/day × 0.40) / 4 = 164 grams/day
- Proteins: (1,643 calories/day × 0.30) / 4 = 123 grams/day
- Fats: (1,643 calories/day × 0.30) / 9 = 55 grams/day
- Using a balanced diet ratio: 40% carbohydrates, 30% proteins, 30% fats
Tracking Your Macronutrient Intake
Once you’ve calculated your macronutrient needs, the next step is to track your intake to ensure you’re meeting your goals. Here are some tips and tools for tracking your macros:
- Use a Food Journal:
- Keep a detailed food journal to record everything you eat and drink throughout the day. Include the type of food, portion size, and macronutrient content.
- Utilize Macro Tracking Apps:
- There are numerous apps available to help you track your macros, such as MyFitnessPal, Cronometer, and MacroFactor. These apps allow you to input your food intake and automatically calculate your macronutrient totals.
- Read Nutrition Labels:
- Pay attention to nutrition labels on packaged foods to determine the macronutrient content. Look for the total grams of carbohydrates, proteins, and fats per serving.
- Weigh and Measure Your Food:
- Use a food scale and measuring cups to accurately portion your food and track your macros. This is especially important for high-calorie and high-macronutrient foods.
- Plan Your Meals:
- Plan your meals and snacks in advance to ensure you’re meeting your macronutrient goals. Prepping meals ahead of time can help you stay on track and avoid impulsive eating.
Adjusting Your Macros
As you progress towards your fitness goals, you may need to adjust your macros to continue seeing results. Here are some tips for adjusting your macros:
- Monitor Your Progress:
- Regularly track your weight, body measurements, and progress photos to assess your progress. If you’re not seeing the desired results, it may be time to adjust your macros.
- Reevaluate Your Caloric Needs:
- Recalculate your BMR and TDEE as your weight and activity level change. Adjust your caloric goals accordingly to maintain a deficit or surplus.
- Adjust Macronutrient Ratios:
- Experiment with different macronutrient ratios to find what works best for your body and goals. For example, you may need to increase your protein intake or reduce your carbohydrate intake to see further progress.
- Consider Cycling Macros:
- Macro cycling involves alternating your macronutrient intake based on your activity level and goals. For example, you may increase your carbohydrate intake on workout days and reduce it on rest days.
- Consult a Professional:
- If you’re struggling to see results or unsure how to adjust your macros, consider consulting a registered dietitian or nutrition coach. They can provide personalized guidance and support to help you achieve your goals.
Common Mistakes to Avoid
When counting macros, it’s essential to avoid common mistakes that can hinder your progress. Here are some mistakes to watch out for:
- Underestimating Portion Sizes:
- It’s easy to underestimate portion sizes, leading to inaccurate macro tracking. Use a food scale and measuring cups to ensure accurate portioning.
- Forgetting to Track Condiments and Sauces:
- Condiments, sauces, and dressings can add significant calories and macros to your meals. Be sure to track these items accurately.
- Not Accounting for Beverages:
- Beverages, including alcohol, soda, and fruit juices, can contribute to your daily caloric and macronutrient intake. Make sure to track these items as well.
- Ignoring Hidden Calories:
- Hidden calories can sneak into your diet through cooking oils, snacks, and mindless eating. Pay attention to these sources and track them accordingly.
- Being Too Restrictive:
- While it’s important to stay within your macronutrient goals, being too restrictive can lead to binge eating and feelings of deprivation. Allow for flexibility and occasional treats to maintain a balanced approach.
