Cutting Diet Calculator
What Is the Cutting Diet Calculator?
The Cutting Diet Calculator is an online tool that helps estimate how many calories you should consume daily during a cutting phase, along with the ideal grams of protein, fat, and carbohydrates to support fat loss while maintaining lean muscle. It takes into account your current weight, body fat percentage, and activity level to deliver tailored nutrition recommendations.
Unlike generic diet advice, this calculator factors in your unique body composition and lifestyle, making your cutting plan more effective and sustainable.
How to Use the Cutting Diet Calculator: Step-by-Step Guide
Step 1: Enter Your Weight
Input your current body weight in kilograms (kg). This is the starting point for determining your calorie needs.
Step 2: Input Your Body Fat Percentage
Provide your estimated body fat percentage (%). This helps the calculator determine your lean body mass, which is crucial for calculating calorie and macronutrient needs.
Step 3: Select Your Activity Level
Choose your typical daily activity level from the dropdown menu:
- Sedentary: Little or no exercise
- Lightly Active: Light exercise/sports 1-3 days per week
- Moderately Active: Moderate exercise/sports 3-5 days per week
- Very Active: Hard exercise/sports 6-7 days per week
- Extra Active: Very hard exercise & physical job or training twice a day
Step 4: Click “Calculate”
Press the Calculate button to generate your personalized cutting diet results.
Step 5: Review Your Results
The calculator will display:
- Calories Per Day: Your recommended daily calorie intake for cutting
- Protein (g): Amount of protein in grams to support muscle preservation
- Fat (g): Recommended grams of fat for hormone balance and energy
- Carbs (g): Remaining calories allotted to carbohydrates for fuel

Practical Example: Using the Cutting Diet Calculator
Let’s say you weigh 75 kg with 18% body fat and you are moderately active. Here’s how you’d use the calculator:
- Weight: 75 kg
- Body Fat %: 18%
- Activity Level: Moderately Active (1.55)
How the calculator works:
- Lean Mass = 75 * (1 – 0.18) = 61.5 kg
- Calories = 61.5 * 33 * 1.55 * 0.8 ≈ 2520 kcal (with approx. 20% deficit)
- Protein = 61.5 * 2.5 = 153.75 g
- Fat = 75 * 0.8 = 60 g
- Calories from fat = 60 * 9 = 540 kcal
- Calories from protein = 153.75 * 4 = 615 kcal
- Remaining calories for carbs = 2520 – (540 + 615) = 1365 kcal
- Carbs = 1365 / 4 = 341 g
These values guide you to eat approximately 2520 calories daily with 154 g protein, 60 g fat, and 341 g carbs — optimal for losing fat while keeping muscle mass intact.

Frequently Asked Questions (FAQs)
1. What is a cutting diet?
A cutting diet is a nutrition plan aimed at reducing body fat while preserving lean muscle mass, typically involving a calorie deficit and adequate protein intake.
2. Why do I need to know my body fat percentage?
Body fat percentage helps calculate lean mass, which is crucial for accurate calorie and macronutrient needs rather than just total weight.
3. How do I measure my body fat percentage?
Methods include skinfold calipers, bioelectrical impedance scales, DEXA scans, or professional assessments.
4. What does “activity level” mean in this calculator?
It reflects your daily physical activity and exercise frequency, impacting how many calories you burn.
5. Why is the calorie target multiplied by 0.8?
This factor applies a 20% calorie deficit, a common strategy for gradual and sustainable fat loss.
6. Can I use this calculator if I’m a beginner?
Yes, it’s designed for anyone wanting to optimize fat loss based on their personal stats.
7. How often should I recalculate my diet?
Every 4-6 weeks or after significant changes in weight or activity level.
8. What if my carbs value is low or zero?
That means your fat and protein needs fill most of your calories; you may need to increase calorie intake or adjust macros for energy.
9. Is fat intake important during cutting?
Yes, fat supports hormone production and overall health even during calorie deficits.
10. Why is protein intake set high (2.5 g per kg lean mass)?
Higher protein preserves muscle mass and supports recovery during fat loss.
11. Can I use pounds instead of kilograms?
This calculator uses kilograms; you can convert pounds to kilograms by dividing by 2.2046.
12. Does this calculator factor in metabolic rate?
It estimates calorie needs based on lean mass and activity level, which correlates closely with metabolic rate.
13. Can women use this calculator?
Absolutely, the calculator works for all genders as it uses lean body mass and activity to tailor recommendations.
14. What if I’m very overweight or obese?
For higher body fat percentages, consider consulting a healthcare professional alongside using this tool.
15. Can this calculator help with bulking?
It’s designed for cutting; bulking requires a different approach with a calorie surplus.
16. How important is meal timing in cutting?
Meal timing is less important than overall calorie and macro balance but can help manage hunger and performance.
17. Should I track my macros with an app?
Yes, apps help ensure you meet your calculated targets daily.
18. Can I adjust the fat and carbs ratio?
You can tweak your macros for personal preference, but it’s best to keep protein consistent.
19. What if I don’t exercise much?
Choose “Sedentary” activity level; this will lower calorie needs accordingly.
20. How accurate is this calculator?
It provides a strong estimate based on proven formulas but individual results may vary; track progress and adjust accordingly.
