Weight Gain Equations:
From: | To: |
The Weight Gain Calories And Protein calculation helps determine the optimal calorie surplus and protein intake needed for healthy weight gain and muscle building, based on your Total Daily Energy Expenditure (TDEE).
The calculator uses the following equations:
Where:
Explanation: A 500-calorie surplus above TDEE promotes steady weight gain of about 0.5kg per week, while 25% of calories from protein supports muscle growth and recovery.
Details: Proper calorie surplus ensures healthy weight gain without excessive fat accumulation, while adequate protein intake supports muscle synthesis, recovery, and overall body composition improvements.
Tips: Enter your accurate TDEE value in calories. The calculator will provide your daily calorie target for weight gain and the corresponding protein intake recommendation.
Q1: Why a 500-calorie surplus?
A: A 500-calorie surplus typically results in about 0.5kg weight gain per week, which is considered optimal for maximizing muscle growth while minimizing fat gain.
Q2: Why 25% of calories from protein?
A: This provides adequate protein for muscle synthesis (1.6-2.2g/kg body weight) while maintaining balanced macronutrient distribution for overall health.
Q3: How do I calculate my TDEE accurately?
A: Use online TDEE calculators, fitness trackers, or consult with a nutritionist. TDEE includes BMR plus activity calories.
Q4: Should I adjust these values over time?
A: Yes, as you gain weight, your TDEE increases. Recalculate every 4-6 weeks or after significant weight changes.
Q5: Are there other important nutrients for weight gain?
A: Yes, carbohydrates provide energy for workouts, and healthy fats support hormone production. Balance all macronutrients for optimal results.
