The best macro ratio for a female doing a body recomposition is high protein (1.8-2.2g per kg of bodyweight), moderate fat (20-30% of total calories), and the rest from carbohydrates. This approach works best when total calories are set at or very close to your maintenance level.
This isn't a magic formula but a reliable starting point. It ensures your body has enough protein to build new muscle tissue while providing enough energy from carbs and fats to fuel workouts and support hormonal health. This method is for women who consistently lift weights and want to change their body composition without extreme dieting.
It is not for complete beginners who may see results with less precision or for advanced athletes preparing for a competition who need more specific protocols. For most women looking to get stronger and leaner, this framework is the most effective path. Here's why this works.
Many people get lost debating the perfect carbohydrate to fat ratio. This is a common mistake. The two most important factors for recomposition are hitting your total calorie and protein targets. As long as you meet those numbers, the exact split between carbs and fats is far less critical for your results.
The mechanism is simple. Adequate protein provides the building blocks for muscle repair and growth, which is triggered by your resistance training. Eating at maintenance calories gives your body the energy it needs to fuel this muscle-building process without storing significant excess fat. If you cut calories too low, you rob your body of the energy needed to build muscle, effectively stopping recomp in its tracks.
Furthermore, protein has the highest Thermic Effect of Food (TEF) of all macronutrients. This means your body burns more calories digesting and processing protein (20-30% of its calories) compared to carbs (5-10%) and fats (0-3%). While not a magic bullet, this gives a high-protein diet a slight metabolic advantage, further supporting the recomposition process.
Think of it like building a house. Protein is the bricks. Calories are the workers' wages. You need enough bricks (protein) and you need to pay the workers (calories) for the house to be built. Arguing about whether the workers should eat sandwiches or pizza for lunch (carbs vs. fats) is secondary as long as they are fed and have bricks to lay. Here's exactly how to do it.
Follow these three steps to find your personal starting point. You will need your bodyweight and a calculator. The goal is to establish a baseline you can adjust over time.
First, estimate your total daily energy expenditure or maintenance calories. This is the amount of energy you need to maintain your current weight. A simple and effective formula is to multiply your bodyweight in pounds by 14-16. Use the lower end (14) if you are less active and the higher end (16) if you are more active.
For example, a 140 lb woman who works out 3-4 times per week would calculate 140 x 15 = 2100 calories. This is her starting point for recomp.
Next, calculate your daily protein goal. This is the most important macro for recomposition. Aim for 1.8 to 2.2 grams of protein per kilogram of bodyweight. To convert pounds to kilograms, divide your weight in pounds by 2.2.
For our 140 lb woman (63.6 kg), the calculation is 63.6 kg x 2.0g/kg = 127g of protein per day. Since protein has 4 calories per gram, this accounts for 127 x 4 = 508 calories.
Now, set your fat intake. Fat is crucial for hormone function. A good range is 20-30% of your total daily calories. Let's use 25% for our example.
For 2100 calories, fat intake would be 2100 x 0.25 = 525 calories. Since fat has 9 calories per gram, this is 525 / 9 = 58g of fat.
Finally, fill the remaining calories with carbohydrates. To find this, subtract your protein and fat calories from your total calories. 2100 (total) - 508 (protein) - 525 (fat) = 1067 calories from carbs. Since carbs have 4 calories per gram, this is 1067 / 4 = 267g of carbs.
So, her starting macros are 127g Protein, 267g Carbs, and 58g Fat. You can track this using a spreadsheet. Or, to make it faster, you can use an app like Mofilo. It lets you scan barcodes, snap photos of food, or search its database of 2.8M verified foods. Logging a meal takes 20 seconds instead of 5 minutes of manual entry.
Your initial macro calculation is a starting point, not a permanent prescription. Your body adapts, so your numbers will need to change. The key is to make small, data-driven adjustments. Track your progress for at least 3-4 weeks before changing anything. Look at strength in the gym, body measurements, and progress photos-not just the scale.
Here’s how to troubleshoot common scenarios:
Scenario 1: Strength is stalling and you feel fatigued.
If your lifts haven't improved for 2-3 consecutive weeks and you feel constantly run down, you're likely under-recovering. Your body needs more energy.
Scenario 2: You're not getting leaner, but strength is good.
If your measurements and photos show no change for a month but your gym performance is solid, your calories may be slightly too high.
Scenario 3: The scale is dropping too fast (more than 1% of body weight per week).
Rapid weight loss during recomp is a red flag for muscle loss. You're in too large of a deficit.
Body recomposition is a slow process. Do not expect dramatic changes in the first few weeks. The scale may not move much at all because you are losing a small amount of fat while gaining a small amount of muscle. This is normal and a sign the process is working.
Typically, you might start noticing visual changes like clothes fitting better or muscles looking fuller within 4 to 8 weeks. However, significant and obvious changes in body composition often take 6 months or more of consistent effort in both training and nutrition. Progress is not linear. Some weeks you will feel strong and lean, other weeks you may feel bloated or flat.
To accurately gauge progress, rely on a combination of metrics. First, take progress photos every 4 weeks in the same lighting and poses. Second, take body measurements (waist, hips, arms, thighs) every 2-4 weeks. Third, track your gym performance meticulously. Are you lifting more weight or doing more reps for the same weight? This is a direct sign of muscle gain. These objective data points are far more reliable than the day-to-day fluctuations of the bathroom scale.
For true body recomposition, you should eat at or very close to your maintenance calories. A large deficit prevents muscle gain, and a large surplus causes excess fat gain. The goal is to give your body just enough energy to build muscle.
It is absolutely essential. Nutrition provides the building blocks, but intense resistance training provides the stimulus for your muscles to grow. Without a challenging lifting program, your body has no reason to build muscle.
It is very difficult. Recomposition requires hitting a specific protein target consistently. Without tracking, it is almost impossible to know if you are eating enough protein to support muscle growth, making your efforts in the gym less effective.
Focus on lean, high-quality protein sources to hit your target without adding excessive fat. Excellent choices include chicken breast, turkey breast, lean beef (93/7 or leaner), fish (like cod, tuna, and salmon), eggs/egg whites, Greek yogurt, cottage cheese, and high-quality whey or casein protein powder.
The menstrual cycle can significantly impact weight, energy, and hunger. In the week leading up to your period (luteal phase), it's common to see water retention cause a 2-5 lb increase on the scale and experience increased cravings. This is temporary. Don't panic and slash your calories. Stick to your plan, understand it's hormonal, and wait for your cycle to start. Your weight will typically return to normal afterward. Listening to your body and perhaps planning for slightly higher carbs during this time can help manage cravings without derailing progress.
