This tool is especially useful for anyone who wants to:

• Avoid guesswork in diet planning
• Optimize nutrient intake for energy and performance

How to Use the Cutting Diet Calculator: Step-by-Step

Using this tool is straightforward. Here’s a step-by-step guide:

Step 1: Enter Your Weight

Input your weight in pounds (lbs). This is a key factor in calculating your lean body mass and total energy needs.

Step 2: Enter Your Body Fat Percentage

Provide your current body fat percentage. This allows the calculator to estimate your lean mass and determine accurate protein requirements.

Choose your daily activity level from the options:

• Sedentary (little to no exercise)
• Light (light exercise 1–3 days/week)
• Moderate (moderate exercise 3–5 days/week)
• Active (hard exercise 6–7 days/week)
• Very Active (intense daily training or manual labor)

Step 4: Input Calorie Deficit Percentage

Enter your desired calorie deficit (e.g., 20%) to create a fat loss plan. A safe deficit typically ranges from 15–25% to avoid muscle loss.

Step 5: Calculate

Click the Calculate button. The calculator will show a progress bar simulating the calculation, and within seconds, your personalized cutting plan will appear.

Step 6: Review Your Results

The tool provides a detailed breakdown including:

• Daily Calories

• Fats (g)

You can copy the results to your clipboard or share them directly on social media.

Practical Example

Let’s say you weigh 180 lbs, have a 20% body fat, are moderately active, and want a 20% calorie deficit.

1. Enter 180 in the weight field.
2. Enter 20 in the body fat percentage.
