Introduction
“So, you’ve decided to try keto—awesome! But here’s the thing: To succeed, you need to nail your macros. What are macros, you ask? They’re the building blocks of your diet: fats, proteins, and carbs. Getting them right is the key to staying in ketosis and reaching your goals. In this guide, we’ll break down how to calculate your keto macros (with examples!) and even give you a free calculator to make it super easy. Let’s get started!”
Section 1: What Are Macros and Why Do They Matter?
Macronutrients (macros) are the three main nutrients your body needs in large amounts:
- Fats: Your primary energy source on keto (70-75% of calories).
- Proteins: Essential for muscle repair and maintenance (20-25% of calories).
- Carbs: Limited to 5-10% of calories to stay in ketosis.
Why Macros Matter:
- Too many carbs = kicked out of ketosis.
- Too much protein = converted to glucose (gluconeogenesis).
- Too little fat = low energy and hunger.
Pro Tip: “Tracking macros ensures you’re eating the right balance for ketosis.”
Section 2: How to Calculate Your Keto Macros
Here’s a step-by-step guide to calculating your keto macros:
Step 1: Determine Your Calorie Needs
- Use an online calculator or this formula:
- Men: BMR = 10 x weight (kg) + 6.25 x height (cm) – 5 x age (years) + 5
- Women: BMR = 10 x weight (kg) + 6.25 x height (cm) – 5 x age (years) – 161
- Multiply your BMR by your activity level:
- Sedentary: x 1.2
- Lightly active: x 1.375
- Moderately active: x 1.55
- Very active: x 1.725
Step 2: Set Your Macro Ratios
- Fat: 70-75% of calories
- Protein: 20-25% of calories
- Carbs: 5-10% of calories
Step 3: Convert Percentages to Grams
- Fat: 1g = 9 calories
- Protein: 1g = 4 calories
- Carbs: 1g = 4 calories
Example:
- Calories/day: 1,800
- Fat: 70% = 1,260 calories ÷ 9 = 140g
- Protein: 25% = 450 calories ÷ 4 = 113g
- Carbs: 5% = 90 calories ÷ 4 = 23g
Pro Tip: “Use apps like Carb Manager or MyFitnessPal to track macros effortlessly.”

Section 4: Example Macros for Different Goals
Here’s what macros might look like for different calorie levels and goals:
Weight Loss (1,500 Calories)
- Fat: 117g
- Protein: 94g
- Carbs: 19g
Maintenance (2,000 Calories)
- Fat: 156g
- Protein: 125g
- Carbs: 25g
Muscle Gain (2,500 Calories)
- Fat: 194g
- Protein: 156g
- Carbs: 31g
Pro Tip: “Adjust your calories based on progress. If you’re not losing weight, reduce by 100-200 calories/day.”
Section 5: Common Macro Mistakes (And How to Fix Them)
- Overeating Protein: Stick to 0.8-1.2g per pound of lean body mass.
- Skipping Fat: Fat keeps you full and energized—don’t fear it!
- Ignoring Net Carbs: Track net carbs (total carbs – fiber), not total carbs.
- Not Tracking: Use an app to log meals and stay on target.
Pro Tip: “Weigh your food with a kitchen scale for accuracy.”
FAQ Section
Q: Can I adjust my macros if I’m not losing weight?
A: Yes! Reduce calories by 100-200/day or increase activity levels.
Q: How often should I recalculate my macros?
A: Every 10-15 lbs of weight loss or if your activity level changes.
Q: Do I need to hit my macros exactly?
A: Aim to stay within 5-10g of your targets, especially for carbs.
