Cutting Phase Formula:
From: | To: |
The Calories And Protein Calculator For Cutting helps determine optimal protein intake and calorie targets during a weight loss phase. It calculates protein needs based on body weight and establishes appropriate calorie deficit for effective fat loss while preserving muscle mass.
The calculator uses the cutting phase formulas:
Where:
Explanation: Higher protein intake during cutting helps preserve lean muscle mass while creating a calorie deficit promotes fat loss.
Details: Adequate protein intake is crucial during calorie restriction to prevent muscle loss, maintain metabolic rate, and support recovery. The appropriate calorie deficit ensures sustainable weight loss without excessive muscle catabolism.
Tips: Enter your current weight in kg, select protein factor (1.6-2.2 g/kg), input your TDEE, and set an appropriate calorie deficit (typically 300-500 kcal for moderate cutting).
Q1: Why use 1.6-2.2 g/kg protein during cutting?
A: Higher protein intake helps preserve muscle mass, increases satiety, and has a higher thermic effect compared to other macronutrients during calorie restriction.
Q2: What is an appropriate calorie deficit?
A: A deficit of 300-500 calories per day is generally recommended for sustainable fat loss of 0.5-1 kg per week while minimizing muscle loss.
Q3: How do I calculate my TDEE?
A: TDEE can be estimated using online calculators that consider age, weight, height, gender, and activity level, or by tracking intake and weight changes over time.
Q4: Should protein intake change during cutting vs maintenance?
A: Yes, protein intake should typically be higher during cutting phases to protect against muscle loss that can occur with calorie restriction.
Q5: How often should I recalculate my needs?
A: Recalculate every 4-6 weeks or after significant weight loss (2-3 kg) to adjust for changes in metabolic rate and body composition.
