Macros for Fat Loss: Cutting and Shredding Guide for Women
Getting lean and defined muscles isn't just about eating less. It's about eating smart.
Understanding macronutrients is your secret weapon for cutting off fat and showing off the lean physique you’ve worked hard to build.
Let's break down exactly how to use macronutrients to help you reach your body composition goals while keeping your energy levels high and your metabolism humming along.
The Role of Macros in Cutting and Shredding
When you're trying to get lean, each macronutrient plays a special part in the process. You can’t expect to lose weight or build muscles or do both if you’re just cutting out calories or adding intake without thinking about where your carbohydrates, protein, and fat are coming from. Your body needs the right kind of nutrients to function at its best.
Getting your macros right helps you burn fat while keeping your muscles fed, which is key to that toned, defined look you’re after.
But here’s the thing, you have different needs from others, especially men. Your body isn’t just a “smaller” version. You have different hormones, and your body handles nutrients differently. This means you need a special approach to macro planning—or your daily diet, in general— that works with your biology.
Ideal Macronutrient Ratios for Women’s Fat Loss
There are multiple macro ratio options available based on your age and what you’re trying to achieve. But for fat loss, specifically, you’ll want to get about 40% of your calories from protein, 30% from carbs, and 30% from fats. However, these numbers aren’t set in stone. They're more like guidelines you can tweak based on how your body responds.
Higher Protein for Muscle Preservation
When you're cutting fat, protein becomes your best friend. Many women often shy away from high protein intake, thinking that high-protein meals aren’t the way to go and protein doesn’t help with weight loss (hint: it does). Although protein is commonly associated with “bulking up,” you don’t get bulky just from eating more protein.
Here’s the truth: your muscles are metabolically active tissue, which means they help you burn more calories even when you’re just chilling on the couch.
So, if you have more muscles and less fat, you’re naturally burning more calories than someone with lesser muscle mass. And this doesn’t always show up as bulk. You can have a toned yet slender physique.
Now, just how much protein you should eat depends on what you want to achieve. If you want to tone your cut, shred, or tone your muscles, aim to eat between 1.6 to 2.0 grams of protein per kilogram of body weight.
So, weighing 60 kilograms means eating between 96 and 120 grams of protein daily. Initially, this might seem like a lot, but you can make it happen without living on protein shakes.
Balancing Carbs for Energy and Recovery
Carbohydrates get an undeserved bad reputation in fitness, but they aren’t the enemy. Your body needs them, especially when you’re working out hard. Finding the right amount that fuels your workouts without stopping fat loss is key.
Nobody wants to feel hangry while trying to get lean, but that’s exactly what’s going to happen if you deprive yourself of carbs. Aim for about 2 to 3 grams of carbs per kilogram of body weight on training days. You might go a bit lower on rest days, but don't cut them out.
Healthy Fats for Hormonal Balance
Cutting out calories is stressful, which affects your body’s hormone levels. Having enough healthy fats combats this, helping your body maintain proper hormone production for stable energy and muscle production.
Aim for at least 0.5 grams of fat per kilogram of body weight. This helps support hormone production without overdoing your total calories. Focus on getting these fats from avocados, nuts, olive oil, and fatty fish.
How to Calculate Your Macros for Cutting
Your journey to successful fat loss starts with understanding exactly how many calories and macronutrients your body needs.
Below, we’ll walk you through finding your perfect numbers.
Establishing a Calorie Deficit for Fat Loss
First, we need to figure out how many calories your body burns each day. This starts with your Basal Metabolic Rate (BMR) – the energy you burn to stay alive. We can calculate this using what's called the Mifflin-St Jeor formula. Don't worry, it's simpler than it sounds. We take your weight in kilograms, multiply it by 10, add 6.25 times your height in centimeters, subtract 5 times your age, and finally subtract 161.
Let's make this real with an example. Take Sarah, a 30-year-old woman who's 165 centimeters tall and weighs 70 kilograms. Her BMR calculation works out to 1,420 calories daily. But that's just the starting point.
Adjusting Macros Based on Activity Levels
Your total daily calorie burn depends on how active you are. Sarah works out four times a week, making her moderately active. We multiply her BMR by 1.55, giving her a total daily energy expenditure of 2,201 calories. Someone with a desk job and minimal exercise would multiply by 1.2, while a very active person might use 1.725.
For fat loss, you'll want to eat less than you burn. Eating 20-25% fewer calories than your total burn is a sweet spot. For Sarah, this means eating between 1,651 and 1,761 calories daily.
Now comes the important part: dividing those calories into proteins, carbohydrates, and fats.
Protein Goals for Shredding
When you're cutting fat, protein becomes your best friend. Research shows that women who are strength-training need between 2.3 and 3.1 grams of protein per kilogram of lean body mass. Your lean body mass is your weight minus your body fat. For Sarah, who has 25% body fat, her lean mass is 52.5 kilograms, meaning she needs between 121 and 163 grams of protein daily.
Setting Carb Intake for Fat Loss
For Sarah’s carbohydrate needs, she’ll want 2-3 grams of carbs per kilogram of lean mass. For her, that's between 105 and 158 grams. On rest days, she can cut this by 30-50%, but should never go below 50 grams to keep her brain happy.
Optimizing Fat Intake
Fat intake comes last. Take your remaining calories after protein and carbs, and divide by 9 to get your fat grams. For Sarah's 1,651-calorie plan, after setting aside calories for 140 grams of protein and 144 grams of carbs, she has room for 57 grams of fat.
This might seem like a lot of math at first, but these calculations set the foundation for your entire fat loss journey. Take time to get them right, and you'll have a clear roadmap to follow toward your goals.

Remember to adjust portion sizes based on your personal calorie and macro targets. You can scale these up or down while maintaining their protein-focused, nutrient-dense nature.
Common Mistakes to Avoid While Cutting
Over-Restricting Calories
Severe calorie restriction sabotages fat loss efforts. When calorie intake drops too low, your metabolism slows down to conserve energy. Your body also breaks down muscle tissue for fuel, which is exactly what we don't want during cutting.
Your body needs at least 1,500 calories daily during a cut. Dropping below this threshold triggers metabolic adaptations that make fat loss harder. Instead of dramatic cuts, reduce calories gradually by 20-25% from maintenance level.
Neglecting Protein Intake
Many women focus solely on calories while cutting, overlooking protein needs. Without adequate protein, you'll lose muscle along with fat. This reduces your metabolic rate and leaves you with a softer appearance, even at a lower weight.
Track protein intake first, aiming for 2.3-3.1 grams per kilogram of lean mass. Split this across 4-5 meals daily. When calories decrease, maintain or increase protein intake to preserve muscle tissue.
Inconsistent Tracking of Macros
Inaccurate eyeballing portions, especially when you’re new and frequent weekend diet breaks derail progress.
Worse still are minor tracking errors. These can and will accumulate, creating a much smaller deficit than planned. Common mistakes include forgetting cooking oils, not weighing meat when raw, and underestimating portion sizes.
Use a food scale and track everything, including sauces and oils. Plan ahead for social events, vacations, and holidays, and more importantly, prepare healthy backup options for busy days.
Tips for Successful Fat Loss and Shredding
The Importance of Strength Training
Strength training prevents muscle loss during cutting. Focus on compound movements like squats, deadlifts, bench presses, and rows, or more intensive forms of certain exercises like Reformer Pilates.
Train each muscle group twice every week and track your lifts so you know that you’re not stagnating. If you’re not lifting more or struggling or plateauing, take a close look at your calorie intake and recovery meals to see if you are feeding your body enough.
Staying Hydrated and Managing Stress
Dehydration mimics hunger and reduces workout performance. Drink water consistently throughout the day and add electrolytes during intense training sessions.
High stress levels increase cortisol, promoting muscle breakdown and fat storage. Prioritize sleep quality, aiming for 7-9 hours nightly. Include recovery activities like walking, stretching, or meditation.
Adjusting Macros as Progress is Made
Monitor progress through weekly weight averages and monthly measurements. When fat loss stalls for two consecutive weeks, make adjustments.
First, reduce carbs by 10%, maintaining protein and fat levels. If progress continues to stall after two more weeks, reduce fat intake. You should only decrease your total daily calorie intake as a last resort.
Recap: Achieving Fat Loss Through Tailored Macros for Women
Like macros for uilding muscles, success in cutting fat and developing a toned physique requires precise macro calculations, consistent tracking, and strategic adjustments. Start with a moderate calorie deficit of 20-25%. Prioritize protein intake while balancing carbs and fats for energy and hormonal health.
Use these guidelines to create a sustainable approach that works for your body and lifestyle. Feel free to adjust them based on your findings. But make sure that you stay consistent for lasting results.
FAQs
What are macros for fat loss, and why are they important?
Macros, short for macronutrients, are protein, carbohydrates, and fats. For fat loss, tracking macros helps you consume the right balance to create a calorie deficit while preserving muscle mass and supporting overall health.
How can I calculate my macros for shredding?
To calculate your macros, determine your total daily calorie needs based on your basal metabolic rate (BMR) and activity level. Then divide your calories into protein, carbs, and fats based on your chosen macro ratio. Tools like macro calculators or apps can simplify this process.
Should women eat fewer carbs when cutting fat?
Not necessarily. Carbs are essential for energy, especially if you are active or strength training. The key is to focus on complex carbohydrates like whole grains, fruits, and vegetables while staying within your macro target.
How often should I adjust my macros during a fat loss phase?
Adjust your macros every few weeks based on your progress. If weight loss stalls or you experience low energy, you may need to lower calories slightly or modify your macro ratio. Tracking consistently helps you identify when changes are needed.
What is the best macro split for cutting fat while maintaining muscle?
A common macro split for fat loss is 40% protein, 30% carbohydrates, and 30% fats. However, the ideal ratio can vary based on individual goals, activity level, and metabolism. Adjusting the balance as needed is key to achieving optimal results.
