Example

Suppose you have the following goal:

• Current weight: 70 kg
• Target weight: 75 kg
• Daily calorie intake: 2500 kcal
• Time frame: 60 days

Step 1: Calculate Total Weight Gain

75 kg – 70 kg = 5 kg

Step 2: Calculate Total Calories Needed

5 kg × 7700 calories = 38,500 calories

Step 3: Calculate Daily Calorie Surplus

38,500 ÷ 60 days = 642 extra calories per day
