How to Calculate Macros for Cutting: A Simple Step-by-Step Guide 2026

• Eat less than you burn. That’s it. No magic.
• Prioritize protein. It preserves muscle.
• Adjust carbs and fats. Based on your energy levels and recovery.

The year I stopped skipping the hard stuff – the nutrition – my physique changed. Not just for show, but for performance. If you’re serious about stripping fat and keeping your hard-earned muscle, you need to know how to calculate macros for cutting. Forget the Instagram gurus selling magic pills. This is about numbers, consistency, and putting in the damn work. This isn’t about chasing a number on the scale; it’s about a sustainable deficit that fuels your workouts and reveals the muscle underneath. We’ve all been there, starving ourselves into oblivion and feeling like shit, only to gain it all back. That ends now. This is the simple, no-BS approach we’ve used to carve ourselves down, time and time again.

Why It Works

Cutting isn’t complicated. It’s a calorie deficit. Plain and simple. Your body needs energy. If you give it less energy than it burns, it has to get that energy from somewhere. Ideally, it taps into your stored body fat. This is the fundamental principle of fat loss. You can do all the cardio in the world, but if your calorie intake is still too high, you won’t see the cuts. The magic happens when you manipulate your macronutrients – protein, carbohydrates, and fats – within that deficit to ensure you’re burning fat, not muscle. Protein is king here. It’s thermogenic, meaning your body burns more calories digesting it. More importantly, it provides the building blocks for muscle repair and growth, signaling your body to hold onto that precious tissue while it digs into fat stores for fuel. Carbs provide energy for your workouts, keeping you from feeling like a limp noodle. Fats are essential for hormone production and overall health. Get these right, and the fat melts away.

Alright, let’s get down to the nitty-gritty. This isn’t a workout program; this is the nutrition framework. We’re talking about building your daily targets.

Here’s the breakdown:

1. Calculate Your Basal Metabolic Rate (BMR): This is the number of calories your body burns at rest. There are plenty of online calculators for this. They use your age, sex, weight, and height. Don’t overthink it; these are estimates.
2. Determine Your Total Daily Energy Expenditure (TDEE): This is your BMR multiplied by an activity factor.

• Sedentary (little to no exercise): BMR x 1.2
• Lightly active (exercise 1-3 days/week): BMR x 1.375
• Moderately active (exercise 3-5 days/week): BMR x 1.55
• Very active (exercise 6-7 days/week): BMR x 1.725
• Extra active (very intense exercise & physical job): BMR x 1.9

This TDEE is roughly how many calories you need to maintain your current weight.

3. Create a Deficit: To cut, you need to eat fewer calories than your TDEE. A safe and effective deficit is usually 15-20% below TDEE, or around 500 calories per day. This typically results in 1-2 pounds of fat loss per week. Too large a deficit, and you’ll feel like garbage, lose muscle, and your metabolism will slow down. We’re not trying to starve ourselves; we’re trying to get lean.

Example: If your TDEE is 2500 calories, a 20% deficit is 500 calories. Your target intake is 2000 calories per day.

4. Set Your Protein Intake: This is the most crucial macro for preserving muscle during a cut. We aim for 1 gram of protein per pound of bodyweight. If you weigh 200 lbs, that’s 200 grams of protein. Protein has 4 calories per gram. So, 200g x 4 calories/g = 800 calories from protein.

5. Set Your Fat Intake: Fats are essential. Don’t go too low. We aim for 0.3-0.4 grams of fat per pound of bodyweight. Let’s use 0.35g for a 200 lb individual. That’s 70 grams of fat. Fat has 9 calories per gram. So, 70g x 9 calories/g = 630 calories from fat.

6. Fill the Rest with Carbs: Now, subtract your protein and fat calories from your total daily calorie target.

• Total Calories: 2000
• Protein Calories: 800
• Fat Calories: 630
• Remaining Calories for Carbs: 2000 - 800 - 630 = 570 calories

Carbohydrates have 4 calories per gram. So, 570 calories / 4 calories/g = 142.5 grams of carbs.

Your daily macro targets for this example:

• Protein: 200g
• Fat: 70g
• Carbohydrates: 143g (rounded up)

This is your starting point. You’ll adjust based on how you feel and perform.

Progression

Progression on a cut isn’t about adding weight to the bar every single week like you would on a bulk. That’s a recipe for disaster. Your primary goal is fat loss while maintaining strength. The progression here is about consistency and adherence.

• Stick to your macros: Track your food intake diligently. Use a food scale – no more guessing. A good kitchen scale is non-negotiable. If you’re not weighing your food, you’re just guessing, and guessing doesn’t get you lean.
• Monitor your body weight: Weigh yourself daily, first thing in the morning, after using the restroom. Take a weekly average. If you’re losing 1-2 pounds per week consistently, you’re on the right track.
• Adjust calories based on results:
• Losing too fast (>2 lbs/week): You might be losing muscle. Increase calories by 100-200, primarily from carbs or fats.
• Not losing weight (<1 lb/week): You need a slightly larger deficit. Decrease calories by 100-200, primarily from carbs or fats.
• Feeling drained and performance is tanking: Your deficit might be too aggressive, or your carb intake is too low. Prioritize carbs around your workouts.
• Maintain training intensity: While you might not set new PRs every week, focus on hitting your target reps and sets with good form. Don’t suddenly drop weights because you’re in a deficit. Your training is what signals your body to keep that muscle. If your strength starts to significantly decline, your deficit is likely too large, or your protein intake is too low.

The key is patience. Fat loss takes time. Don’t make drastic changes. Small, consistent adjustments are the way to go.

Form Cues & Common Mistakes

This isn’t about lifting form; it’s about nutrition form. The mistakes here are just as costly as a rounded back on a deadlift.

• Mistake 1: Guessing your portions. This is the number one killer of cutting diets. You think you’re eating 2000 calories, but you’re actually eating 2800. That extra handful of nuts? Those three bites of your kid’s dinner? It adds up. Solution: Use a food scale. Every. Single. Time. Weigh your chicken, your rice, your peanut butter. Be brutal with yourself.
• Mistake 2: Cutting carbs too low, too soon. Bro-science often screams “low carb” for fat loss. While carbs are a negotiable macro, dropping them too drastically will kill your energy, your workouts, and your mood. You’ll feel like crap, and your performance will plummet, which can lead to muscle loss. Solution: Keep carbs at a reasonable level, especially around your workouts. Fuel your training, then let the deficit work.
• Mistake 3: Underestimating liquid calories. Sodas, juices, fancy coffees, alcohol. These are empty calories that don’t fill you up and can easily blow your deficit. You can drink your way out of a fat loss phase without even realizing it. Solution: Stick to water, black coffee, and unsweetened tea. If you’re going to have alcohol, factor it into your daily calories and understand its impact on recovery and appetite.
• Mistake 4: Not eating enough protein. We hammered this, but it bears repeating. If you’re not getting at least 1 gram per pound of bodyweight, you’re leaving muscle on the table. Your body will break down muscle for energy if it doesn’t have enough protein. Solution: Make protein your priority. Every meal should have a solid protein source. Eggs, chicken, fish, lean beef, protein powder – whatever it takes.
• Mistake 5: Giving up too soon. You’ll have days where the scale doesn’t move, or it goes up slightly. That’s normal. Water retention, sodium intake, and the menstrual cycle (for women) can all affect the scale temporarily. Don’t panic and don’t ditch the plan. Solution: Stick to your average weekly weight loss. Trust the process. Consistency over perfection.

FAQ

How do I adjust my macros if I feel too tired? If you’re consistently feeling drained and your workouts are suffering, your deficit might be too aggressive, or your carb intake is too low. Try adding 100-200 calories, primarily from carbohydrates, especially in the meals surrounding your training sessions. Ensure your protein intake remains high.

What’s a good protein powder for cutting? Any high-quality whey protein isolate or casein protein will work. The key is that it’s low in carbs and fats. We use whey protein isolate to hit our protein goals easily. It’s a convenient way to get protein on the go or after a tough workout.

How long should I stay in a cutting phase? This depends on your body fat percentage and goals. Generally, 8-16 weeks is a common timeframe. Going too long can lead to metabolic adaptation and burnout. It’s crucial to listen to your body and consider taking diet breaks or reverse dieting afterward to recover.

Is cardio essential for calculating macros for cutting? Cardio can help create a larger calorie deficit, allowing you to eat slightly more food while still losing fat, or speed up fat loss. However, it’s not strictly necessary if you can achieve your desired deficit through diet alone. Prioritize resistance training to preserve muscle.

What if my weight loss stalls after a few weeks? A plateau is normal. If your weight has stalled for 1-2 weeks despite adhering to your macros, it’s time for a small adjustment. Decrease your daily calorie intake by another 100-200 calories, or increase your activity slightly. Don’t make drastic changes; small tweaks are more sustainable.

Conclusion

Calculating your macros for cutting isn’t rocket science. It’s about understanding the fundamentals of energy balance and prioritizing protein. Stop chasing magic bullet solutions and focus on the numbers. Your TDEE, a sensible deficit, and hitting your protein target are the cornerstones of effective fat loss. Don’t let bro-science or ego lifting sabotage your progress. Today, your next step is simple: calculate your TDEE and set your initial macro targets. Use a reliable calculator, be honest about your activity level, and then commit to tracking your food intake for the next seven days. No excuses. This is the work. Get after it.
