How the Meal Plan Calculator Works

The Meal Plan Calculator uses scientifically backed nutrition formulas to estimate your daily energy needs and distribute them into balanced meals.

Key Inputs Required:

To generate an accurate meal plan, users typically enter:

• Age
• Gender
• Weight
• Height
• Activity level
• Fitness goal (weight loss, gain, maintenance)
• Dietary preference (vegetarian, vegan, keto, etc.)
• Number of meals per day

Core Logic Behind the Tool:

1. Basal Metabolic Rate (BMR) Calculation
   Determines how many calories your body needs at rest.
2. Total Daily Energy Expenditure (TDEE)
   Adjusts calorie needs based on physical activity.
3. Goal-Based Adjustment
   • Weight loss → calorie deficit
   • Weight gain → calorie surplus
   • Maintenance → balanced intake
4. Macro Distribution
   Calories are divided into:
   • Proteins
   • Carbohydrates
   • Fats
5. Meal Splitting
   Daily calories are distributed across breakfast, lunch, dinner, and snacks.
