Scientific Foundation

Evidence-Based Approach

Our nutrition calculator incorporates principles from peer-reviewed research in nutrition science, sports medicine, and metabolism. We combine established formulas with contemporary research findings to create recommendations that are both scientifically valid and practically applicable.

The calorie targets, macronutrient distributions, and meal timing strategies are derived from studies on energy balance, body composition, muscle protein synthesis, and hormonal responses to different dietary protocols.

Key Research Areas

  • Energy balance and metabolic adaptation
  • Protein requirements for muscle preservation and growth
  • Meal frequency and nutrient timing effects
  • Dietary adherence and behavior modification

Formulas & Calculations

Mifflin-St Jeor Equation (BMR)

Men: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age) + 5

Women: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age) - 161

Activity Multipliers (TDEE)

Sedentary: BMR × 1.2

Lightly Active: BMR × 1.375

Moderately Active: BMR × 1.55

Very Active: BMR × 1.725

Extremely Active: BMR × 1.9

Protein Requirements

General Health: 0.8-1.0g per kg of bodyweight

Active Individuals: 1.2-1.7g per kg of bodyweight

Weight Loss: 1.6-2.2g per kg of bodyweight

Muscle Building: 1.8-2.4g per kg of bodyweight

Caloric Adjustments

Moderate Fat Loss: TDEE - 500 calories (≈0.5kg/week)

Aggressive Fat Loss: TDEE - 1000 calories (≈1kg/week)

Maintenance: TDEE

Moderate Gain: TDEE + 250 calories (≈0.25kg/week)

Muscle Building: TDEE + 500 calories (≈0.5kg/week)
